Human health and nano-fertilizers – where is the safety clothing?

Published

By Chandre Dharmawardana,

The rationale for banning agro-chemicals in May 2021 and “going all organic” was mostly the claimed (but false) “poisoning of the food chain” by “chemicals”. It was well known that organic farming even at its best can only supply a tiny fraction of any nation’s food requirements, unless drastic steps are taken (like halving the population and forcing all to be vegetarians; see https://www.dh-web.org/green/CD-Mueller-OrganicL.pdf). Today, having realized the impossibility of providing the vast amount of “organic fertilizer” needed even to get minimal harvests and avert famine, the government has done a knee-jerk purchase of nano-fertilizer from India.

A government working in the crisis mode has NOT asked if nano-urea can be a health hazard to farming communities, and instead accepted what the Indians say. The product was launched only on 31st May 2021 and sells in India at about $3-4 for a 500ml bottle. It is claimed that 11,000 farm trials were conducted by the Indian National Agriculture Research System in the preceding years. Looking at the published materiel I suspect that these only looked at yields and did NOT monitor the health of the farming communities. The preceding years even overlapped with the pandemic when health chaos prevailed.

Whether with DDT, thalidomide, glyphosate or nuclear waste, the impact on human health requires studies over several generations. With conventional materials, tests on micro-organisms and smaller animals with short life spans provide useful information. But this is not true for nanoparticles as their toxico-kinetic pathways are still quite unknown. Although the Indians say that the nano-urea has been tested for bio-safety and toxicity following Indian government guidelines as well as OECD “international guidelines”, no details have been published. It is an open secret that there are no accepted OECD guidelines for the toxicity of various nanomaterials. The earliest nanourea declared nearly two decades ago in the CN1269774C Chinese patent, other products like the hydroxy-apatite nanourea from SJP university which is a few years old, or the Indian product which is only a few months old, have not been adequately investigated for their environmental and health impact.

The claim by the Indians that their product is “eco-friendly” and safe to humans is an unsubstantiated statement, very likely to be false.

Nanoparticles are ultra-small. Their size is that of Covid-19 Corona virus particles. Being ultra-small, nanoparticles penetrate into foliage, roots or soil extremely efficiently. These materials, especially when sprayed, can get into human skin, eyes, ears, lungs, intestines etc., and instantly penetrate through epithelial layers into every organ and cell, womb and fetus, brain and neuron, chromosome and gene. They will act with high efficiency becoming hundreds of times more toxic than the parent substance from which the nanomaterial was manufactured. While the nanoparticle penetrates the foliage like a “magic bullet”, their action on soil and leaf organisms, and pollinating insects can be akin to a “cluster bomb” that destroys indiscriminately.

Lung inflammation, granuloma, and focal emphysema are found in studies on SiO2 nanoparticles. Gold nanoparticles are used in food technology and found to cause chromatin changes in the nucleus of human lung fibroblasts, making changes in gene expression in mouse fetus leading to lung cancers. Silver nanoparticles enter the intestinal mucus barrier and increase oxidative stress, damaging cell membranes, DNA, and chromosomes as well. Even at low concentrations, the toxicological effects of silver nanoparticles become evident, while abnormal cell damage, shrinkage, apoptosis, and skin cancers occur at higher concentrations.

Use of nanofertilizers creates a sophisticated agricultural industry that is the future. Nanofertilizers will increase yields, but they should be deployed with highly sophisticated safety clothing and usage protocols. Full-face masks and overalls should be unpenetrable to nanoparticles. The nanomaterials must be applied by trained farm technicians with the discipline of semi-conductor “clean-room” technicians who engage in the fabrication of nanomaterials.

My research on nanomaterials at the National Research Council of Canada since the 1980s have been for optical and electronic technologies where sealed fabrication plants are used in manufacturing. Similarly, in the context of agriculture, I have long advocated that the steps beyond the green revolution are these sophisticated technologies, but deployed within “sky-scraper” grow towers sealed from the environment, thereby freeing up farmland for reforestation. The alternative of using these technologies in the unprotected environment is like releasing synthetic viruses (nanoparticles) into ecosystems whose evolutionary tools have no defense against them.

Let us forget about the environment for the short term and ask about human safety. Where is the necessary nano-impregnable clothes and masks for the 1.2 million farmers who spray the nanourea? Furthermore, Nanourea should be sprayed so that the flora and fauna other than the targeted plants are spared. The long-term effects of such exposure are UNKNOWN at present.

In contrast to nanomaterials, conventional agrochemicals have been used for many decades. Substances like glyphosate or DDT have faced large-scale studies and periodic reviews sinCe the 1970s. The large-scale health study of the US government on Glyphosate with its adjuvents involved monitoring some 54,000 farming families over nearly a quarter century, ended in 2018 and established its safety. There had been many in-depth studies on most agrochemcials, and in many countries. In contrast, nanofertilizers have been available for a very short time, and we do not have reliable health-safety guidelines for these new materials.

The agricultural policies of the present government, or the previous government had been increasingly set by pseudoscience activists mesmerized by elite-class propaganda about creating toxin-free environments for themselves. They get their cues from wealthy environmental NGOs in California and Europe that list genetically engineered food as “Franken-food”. The local movement was strengthened by nationalists who equated traditional agriculture to “organic farming”, and by leftists who “heroically” target multinationals like Bayer-Monsanto.

So an unlikely combination of Colombo-7 tree-saving (“Ruk-Raekaganno”) types, Buddhist monks like Ven. Ratana, Marxist-inspired MONLAR activists, “Nath Deviyo” inspired shamans like the late Ms. Senanayaka of “Helasuvaya”, misguided academics like Dr. Nalin de Silva and their acolytes, lined up with medical doctors like Anurddha Padeniya of the GMOA, and Sanath Gunatilleke of California inspired by figures like Stephanie Seneff and “Dr”. Mercola.

Their band wagon blamed every non-communicable disease on agrochemicals. The rise of an unusual form of Kidney disease, now believed by many researchers to be caused by geologically polluted water containing fluorides and other salts was a trump card for them. A staunch supporter of traditional agriculture (and traditional medicine) could write (quite incorrectly) that “Paddy and other cultivations have been done in this country for thousands of years without chemical fertilizer. During these times there were no serious CKD problems. Started using Chemical Fertilizer from 1950s and after about 20 – 30 years serious CKD problems arose”.

Meanwhile scientists themselves had rightly begun to express serious concern over the excessive use of agrochemicals and the degradation of the soil and environment. This had begun to occur after the arrival of an uncontrolled “free” market, further primed by subsidized fertilizers.

So, the stage was set for tighter restrictions on agrochemicals. Instead, the Toxin-Free bandwagon set the pace. First came a ban on the popular herbicide “RoundUp” by the Sirisena government. Ven. Ratana was Sirisena’s prime mover in agriculture. This debilitated all agricultural sectors, causing a loss of at least three times the bond scam, and created the prospect of a collapse of tea exports. However, ideologically driven movements do not learn from evidence, and the present government decided to outsmart not only the Srisena government, but all other nations, by becoming the first to “go 100% organic” by banning all agrochemicals.

That ban was imposed like a bolt from the blue in May 2021. Even the military was diverted to making compost, while shipments of “chemical” fertilizers and pesticides were turned away. That it was impossible to generate enough organic fertilizer, containing at most a mere 2% of nitrogen to replace urea fertilizer with 46% N dawned on the government planners only when their yeoman efforts failed. This had been predicted in our earlier articles, already during the Sirisena era when the threat of the so-called “toxin-free” agriculture had loomed over the country.

So, in trying to create a “toxin-Free nation” based on 100% organic, a desperate government has come to its very antithesis, i.e., very high technology that deals only with artificial materials that are beyond anything organic or inorganic. It plans to explode a cluster bomb of nanoparticles on a fragile ecosystem and an unsuspecting citizenry.

Sections of US media looking power straight in the eye

Published

on

President Trump addressing the media at the White House.(BBC)

Some fundamental freedoms seen to be at the heart of democracy in the US – religion, speech, the press, assembly and the right to petition the government – are at risk of being undermined at present by the country’s Executive President. However, the latter is being legally challenged on this score by some sections of the US media and the citizenry of the country could take heart from this notable defense of media freedom.

In fact this is good news for the world of democracy. The push back is coming from organizations such as CNN, ABC, CBS, Fox, NBC who constitute the nucleus as it were of the US media and their solidarity no less than their resourcefulness calls for commendation.

Following a recent White House decision to suspend CNN from what was referred to as ‘participation in presidential pool coverages’, the other media organizations mentioned refused to replace it in the pool. Their position was that the public had a right to receive ‘accurate and independent information about the government.’

Earlier, the White House decided to bar MS NOW and Politico from entering its premises following the restrictions imposed on CNN. The organizations were accused of publishing “FAKE NEWS’ , ‘Fiction’ and ‘lies’ in respect of the administration. These organizations lost no time in initiating a federal lawsuit accusing the central administration of violating their rights guaranteed by the First Amendment.

However, the latter litigating organizations could now consider themselves as having been vindicated because the federal court hearing their case has ordered the Trump administration to temporarily restore White House press access to journalists from the mentioned media institutions. Notably, the court has declared that the ban is ‘likely unconstitutional’. The case is proceeding.

The mass media of the most vibrant democracies of the West ought to be no strangers to such inspirational acts of solidarity and exemplifications of independence but there are lessons here for the democracies of the South that could stand them in good stead. Minus the right of a people to be informed, the rest of fundamental rights featuring in Southern Bills of Rights and legislation of the kind are bereft of substance and meaning.

It is informed decision-making on the part of a citizenry that makes for democratic vibrancy and on this score many a Southern democracy fails. While Southern publics generally demand of their governments continuous economic well being and substantive material benefits they are not equally desirous of being informed and knowledgeable.

This lacuna in the consciousness of many Southern publics enables their governments ‘to get off the hook’, so to speak and govern, or more often misgovern, their countries with impunity. Among other factors, this species of mass ignorance makes it possible for governments to dismantle democracy and rule in perpetuity.

Accordingly, an educated and constantly informed public is an essential precondition for the flourishing of democracy and independent media are integral to this process. Minus an independent mass media sector that meets the knowledge needs of the people responsibly, democracy is as good as dead.

Needless to say, those sections of the US media that are currently taking the Trump administration to task over its media curbs are acutely aware of the cruciality of these fundamental knowledge requirements.

The hope of democratic opinion worldwide and locally is likely to be that media independence would thrive in the manner in which it is flourishing in the most vibrant and accountable democracies of the West.

Southern countries such as Sri Lanka that lay claim to democratic credentials, but are democracy-deficient in many ways, need to be particularly cognizant of these requirements. The publics of these countries need to go the extra mile to ensure the thriving of an independent but responsible mass media sector.

In fact it is veritably a matter of life and death. It is only an independent media sector that could, while ensuring the existence of an informed public, impress on the latter the need to protect and perpetuate its fundamental rights. In the absence of these campaigns, such publics could be eventually having on their hands governments that boast of ruling in perpetuity.

Taking a leaf from the sections of the US media referred to independent media organizations in Southern states need to act in solidarity as well. They would need to act on the basis of the principle that acts of victimization suffered by members in their fold at the hands of governments, for instance, are in fact inimical acts directed at their collectivity and which call for united remedial action. In short, no independent mass media institution could see itself as ‘an island’.

Besides some general guidance on the importance of media independence and solidarity, the message coming from the US with regard to media praxis is that power must be stood-up to unblinkingly. The mentioned sections of the US media are primarily in a struggle to ward off encroachments on their independence in the areas of policy and practice by the political executive, that is the President.

The latter would ride rough-shod over the media in the absence of robust opposition by the media itself to inimical executive action of this kind.

While media independence needs to be seen as crucial to democratic development, an obligation is cast on the media to ensure that it uses such independence responsibly and constructively.

The worst that could afflict a media sector is for it to fall prey to the clichetic ‘freedom of the wild ass’. In fact recurring irresponsibility on the part of the media could lend credence to the perception that a tightly regulated media is best for a country. It is a short step from this misguided view to the position that political authoritarianism is best for a state. That turn of events would be of course catastrophic for a democracy.

The issues discussed thus far point to the need for a broad discourse among Southern democracies in particular on what is best for them in this connection. Given the risks underscored earlier for Southern countries in particular a broad discussion on the matters at hand, which includes the public, emerges as a must for Sri Lanka. Besides, media solidarity within democratic countries and internationally is a must.

What lessons can be learned to improve quality of Sri Lanka’s Grade 6 syllabus

Published

on

Prime Minister Dr. Harini Amarasuriya

by Prof. M. W. Amarasiri de Silva

Following public controversy over an inappropriate web link found in an English study module, the Sri Lankan government formally deferred the full rollout of the Grade 6 curriculum reforms to January 2027. In the interim, state schools will maintain the existing syllabus, reverting to standard eight-period daily timetables and previous textbooks to ensure uninterrupted instruction. Prime Minister and Minister of Education Dr. Harini Amarasuriya emphasized that this temporary pause allows the Education Ministry to thoroughly review all instructional materials, fix editorial flaws, and conduct scientific impact assessments across pilot schools prior to nation-wide implementation.

To address the oversight, an expert committee evaluated the flawed materials, completed necessary amendments, and finalised discussions to resubmit corrected modules for printing. Beyond revising written texts, the Ministry established a broader preparation roadmap—allocating funds for extensive teacher training programs set to begin mid-year, alongside scheduled informational briefings for parents, teachers, and students. Prime Minister Amarasuriya reaffirmed that none of the valid first-term modules were completely discarded or scrapped, preserving state resources while systematically rebuilding public trust and strengthening quality assurance protocols.

In this respect, this article reviews the current grade 6 syllabus comparing it with similar syllabi of India and the USA, with a view to make recommendations for the upcoming grade 6 syllabus revision.

Architecture of nation’s future

Education is the quiet architecture of a nation’s future. It is the unseen scaffolding upon which generations build their character, their intellect, and their capacity to contribute meaningfully to society. In Sri Lanka, the Grade 6 syllabus occupies a particularly important place in this architecture. It is the bridge between primary learning and the more demanding intellectual terrain of secondary education. It is the moment when children begin to move from learning basic facts to understanding concepts, from memorising information to applying knowledge, and from passive reception to active engagement. Yet, despite its importance, the Grade 6 curriculum in Sri Lanka has long struggled with issues of breadth, depth, relevance, and pedagogy. As global education systems evolve, Sri Lanka must examine what lessons can be learned from international models—particularly India and the United States—to strengthen its own curriculum and prepare students for a rapidly changing world.

The first lesson Sri Lanka can learn is the value of conceptual clarity. India’s NCERT curriculum, especially in Mathematics and Science, is globally respected for its logical progression and conceptual depth. Indian students are introduced early to the idea that mathematics is not merely a set of procedures but a language of reasoning. They learn why a ratio works, not just how to compute one. They understand the structure of an equation, not merely the steps to solve it. In Science, they explore the properties of materials, the structure of plants, and the principles of motion with a clarity that encourages curiosity rather than rote memorisation.

Sri Lanka’s Grade 6 syllabus, while competency-based, often leans heavily toward content coverage. Students are expected to learn many topics, but the time allocated for each is limited, and the teaching culture often emphasizes memorisation over understanding. If Sri Lanka wishes to improve the quality of its syllabus, it must embrace the idea that fewer topics taught well are better than many topics taught superficially. Conceptual mastery builds confidence, and confidence builds lifelong learners.

Lesson from the US

A second lesson comes from the United States, where the curriculum is built around skills rather than content. American students in Grade 6 are expected to read complex texts, analyse arguments, write essays supported by evidence, conduct experiments, and engage in collaborative projects. The emphasis is not on how much they know but on what they can do with what they know. This skills-based approach encourages critical thinking, creativity, and independence—qualities essential for success in the modern world.

Sri Lanka’s syllabus, by contrast, often rewards students for reproducing information rather than interpreting it. The exam culture reinforces this tendency, as students are assessed primarily through written tests that measure recall. To improve the syllabus, Sri Lanka must integrate more opportunities for students to think, question, debate, and create. The classroom should become a space where students learn to solve problems, not just memorize solutions.

Another important lesson comes from the breadth of Sri Lanka’s own curriculum. One of the strengths of the Sri Lankan system is its inclusion of cultural and religious education. Subjects such as Buddhism, Hinduism, Islam, and Christianity provide moral grounding and cultural identity. Art, Music, Drama, and Health contribute to holistic development. These subjects remind students that education is not merely about academic achievement but about becoming a balanced human being. However, breadth without depth can become burdensome. Grade 6 students in Sri Lanka often juggle more than ten subjects, each with its own textbook, competencies, and assessments. This creates pressure not only for students but also for teachers, who must rush through content to meet syllabus requirements. The lesson here is not to reduce cultural subjects but to integrate them more meaningfully. Religious education can be taught through ethical discussions, community projects, and reflective writing. Art and Music can be connected to history, literature, and social studies. Health can be linked to science and physical education. Integration reduces overload while enriching learning.

Another lesson from India

India offers another valuable lesson in the form of standardised textbooks. NCERT books are used across the country, ensuring consistency in quality and content. They are written by subject experts, reviewed rigorously, and updated periodically. Sri Lanka’s textbooks, while generally well-structured, vary in quality and often lag behind modern pedagogical standards. Some are dense, text-heavy, and lacking in visual aids or real-world examples. To improve the syllabus, Sri Lanka must invest in high-quality textbooks that are engaging, accessible, and aligned with contemporary educational research. Textbooks should not merely transmit information; they should inspire curiosity. They should include stories, diagrams, experiments, and activities that make learning enjoyable and meaningful.

The United States provides a lesson in inquiry-based science education. American students conduct experiments, build models, observe natural phenomena, and engage in engineering design challenges. They learn science not as a set of facts but as a process of discovery. Sri Lanka’s science curriculum includes experiments, but many schools lack the resources, laboratory facilities, or teacher training to implement them effectively. Improving the syllabus requires improving the ecosystem around it. Schools need laboratories, equipment, and teacher development programs that empower educators to teach science through inquiry. A syllabus is only as strong as the environment in which it is taught. ***

International models

Another area where Sri Lanka can learn from international models is language education. In India, students often learn three languages—English, Hindi, and Sanskrit or Urdu. This heavy language load has its challenges, but it also produces students with strong linguistic skills. In the United States, English Language Arts emphasises reading complex texts, writing arguments, and analysing literature. Sri Lanka’s English curriculum, while improving, still struggles with uneven implementation across schools. Many students reach secondary school without adequate proficiency in English, limiting their access to global knowledge. To improve the syllabus, Sri Lanka must strengthen English instruction through better teacher training, more reading opportunities, and a shift from grammar-heavy teaching to communication-focused learning. At the same time, Sinhala and Tamil instruction should be modernised to include creative writing, literature appreciation, and critical reading.

Social Studies is another area ripe for improvement. Sri Lanka’s curriculum includes History, Geography, and Civics, but the teaching often emphasises memorization of dates, definitions, and facts. India’s Social Science curriculum, while also content-heavy, provides clearer conceptual frameworks. The United States, however, excels in teaching civics and citizenship. American students learn how governments function, how laws are made, how communities solve problems, and how citizens participate in democracy. Sri Lanka can strengthen its Civics curriculum by incorporating more discussions on governance, rights, responsibilities, and community engagement. Students should learn not only the structure of government but also the values that sustain it—justice, equality, and participation.

One of the most important lessons Sri Lanka can learn is the value of reducing exam pressure. In both India and Sri Lanka, exams dominate the educational landscape. Students are judged primarily by their ability to perform on written tests. The United States, while not free from assessment challenges, uses a wider range of evaluation methods—projects, presentations, portfolios, and continuous assessment. These methods allow students to demonstrate learning in diverse ways. Sri Lanka should consider adopting a more balanced assessment system that values creativity, collaboration, and practical skills alongside academic knowledge.

Technology integration is another area where Sri Lanka can improve. The United States incorporates digital literacy, coding, online research, and digital citizenship into the curriculum. Sri Lanka’s ICT syllabus is well-structured, but implementation varies widely. Many schools lack computers, internet access, or trained ICT teachers. Improving the syllabus requires improving infrastructure. Students must learn to navigate the digital world safely and effectively. They must learn coding not as a luxury but as a basic skill. They must learn to evaluate online information critically, a skill essential in an era of misinformation.

Teacher training

Teacher training is perhaps the most critical lesson of all. A syllabus is only as effective as the teachers who deliver it. India invests heavily in teacher training through national programs, workshops, and online platforms. The United States emphasises professional development, peer collaboration, and instructional coaching. Sri Lanka must strengthen its teacher training programmes, ensuring that educators understand not only what to teach but how to teach it. Teachers should be trained in inquiry-based learning, differentiated instruction, formative assessment, and classroom management. They should be empowered to adapt the syllabus to the needs of their students rather than follow it mechanically.

Sri Lanka must learn the lesson of relevance. A syllabus must prepare students not only for exams but for life. It must teach them how to think, how to communicate, how to solve problems, and how to work with others. It must prepare them for a world where knowledge is abundant, but wisdom is scarce. It must help them navigate a future shaped by technology, globalisation, environmental challenges, and social change. To improve the syllabus, Sri Lanka must ask: What kind of citizens do we want to produce? What kind of thinkers? What kind of leaders? The answers to these questions should shape the curriculum.

Lastly, improving the quality of Sri Lanka’s Grade 6 syllabus requires learning from both international models and local strengths. From India, Sri Lanka can learn the value of conceptual clarity and standardised textbooks. From the United States, it can learn the importance of skills, inquiry, and creativity. From its own traditions, it can preserve cultural education, moral development, and holistic learning. The goal is not to copy another country’s system but to build a uniquely Sri Lankan curriculum that is modern, relevant, and empowering. A curriculum that honours the past while preparing students for the future. A curriculum that nurtures thinkers, creators, and compassionate citizens. A curriculum worthy of a nation with immense potential and a proud educational heritage. If Sri Lanka embraces these lessons, the Grade 6 syllabus can become not just a bridge to secondary education but a foundation for national progress.
