Absurd standardss on Cadmium and Lead in fertilizers
An opposition member of parliament, Dr Harsha De Silva raised the issue of “contaminated” fertilizer stocks in the House. News reports and social media state that fertilizers “Laced with Unsafe Levels” of Lead and Cadmium have been released in Sri Lanka. Exposure to even small amounts of these heavy metals over time, mainly through the food chain, or by smoking, causes kidney, liver, bone and neurological damage in humans, leading to a variety of chronic diseases.
According to the news reports “The SLSI had suspended the release of the TSP consignment after it found that Lead and Cadmium in the imported fertilizer were higher than the maximum levels for toxic elements based on Sri Lanka standards specifications……However, following a meeting at the Presidential Secretariat, Director Senaratne authorized the release of the consignment into the market, on a strictly conditional basis, considering the food security of the country”.
Anyone reading the news would be justifiably alarmed, as both cadmium and lead are toxic substances that should not get into the food chain, even in small concentrations. However, we point out here that the fault is not in the imported fertilizer, but in the ridiculous standards stipulated by those who wrote Sri Lanka’s standards for heavy metal residues in fertilizers. This is a topic that I have addressed in newspaper articles as well as in technical studies [e.g., Dharma-wardana, Environmental Geochemistry and Health volume 40, pages 2739–2759 (2018) ].
This report must be taken in the backdrop of news about toxins in coconut oil, as well as the attempt of a TV-media host to make the SL Standards Institute (SLSI) Director Dr. Senaratne to reveal names of companies alleged to have imported contaminated coconut oil. She quite correctly stood her ground and declined to reveal names and make public accusations.
The Director of a scientific laboratory is not mandated to act as a public prosecutor. However, her answer showed that scientists are not media savvy and may give totally inappropriate answers that media outlets seek to create media hype. The fact that media hosts should try to destroy due process, and create “instant exposés” in an inappropriate manner, show the extent of the decline in public standards of justice and fair play in the country.
However, let us use this opportunity to educate ourselves regarding toxic substances in general, and heavy metals in fertilizers, in particular. Due to lack of space, here we examine only the case of cadmium, whose Sri Lankan standards are stated in SLS-812-standard-1988, amended and re-approved in 2008. This says that a kilo of TPS fertilizer cannot contain more than 5 mg of cadmium (or 10.9 mg per kg of P2O5). This is an absurd specification, which is impossibly LOW, such that there are very few mineral sources that conform to such a specification.
Let us look at this in comparison with the standards required by other countries for cadmium in fertilizer.
Each country, and sometimes each state or province of a country, sets its standards based on the naturally existing cadmium levels in its soil. Most parts of the UK have very high cadmium levels in its soil, and so inputs of Cd via fertilizers make little difference. Some parts of Western Europe (e.g, Brittany, in France, or parts of Holland) have low natural levels, while Belgium is as contaminated as the UK. So the European Union, as a whole, hopes to gradually tighten its standards and move to 20 mg/kg by 2040. But Sri Lanka has already, in 1988 itself, set its Cd limit at the impossibly low value of 5 mg/kg !
Was this very low limit set already in 1988 so as to disallow every imported batch of fertilizer, so that it can be allowed only when the right pockets are filled? Did the ring of racketeers with greased palms get broken, or did it not change with the change of government, and was this the reason why this matter had to go right up to the top for the “approval” of a perfectly safe and fine fertilizer? The fertilizer has been “condemned” as being “laced with cadmium” and other heavy metals using deliberately contrived specifications ?
How clean the food you eat depends fundamentally on the cleanliness and ecology of the soil to start with. It is only secondarily dependent on the purity of fertilizers in regard to trace metals, or the presence of traces of pesticides; even though a very different hype has been developed in the media for the consumption of a public frightened for its health and ready to even believe people like Dr. Mercola (see:
http://www.dailynews.lk/2018/11/07/features/167704/toxic-cocktail-myth-and-truth) or even “Dr”. Dhammika Bandara inspired by Kaali Amma.
All soils have a certain amount of naturally occurring toxins, as well as toxins from human activity, e.g, earth works, mining, farming, burning of fossil fuels or forests that cause acid rain and noxious fumes, and poor disposal of garbage. Even organic farming, often believed to be clean and “natural”, produces toxins similar to those in mineral fertilizers, as composting plant matter leads to the cyclic accumulation of heavy metals like cadmium and lead found naturally in the soil, and re-concentrated in plant matter used for composting.
Mineral fertilizers like triphosphate (TPS) are mined from the ground, usually from desert locations (e.g., in Morocco, Nauri Islands in New Zealand). These mineral deposits are becoming increasingly scarce and phosphates are a threatened commodity. Mineral fertilizers applied to the soil also contribute some cadmium (and other trace metals) to the soil.
Let us take an “extremely polluted sample” of fertilizer by Sri Lanka’s specification, e.g. Nauru phosphate which has some 90 mg/kg of cadmium, i.e., 15 times more than that specified by the current absurd SL standard. We have shown (e.g., https://doi.org/10.1007/s10653-018-0140-x)
that it will still take many centuries to modify the cadmium levels in, say, Sri Lankan soil significantly by such fertilizer additions. Hence even such a so-called “bad” fertilizer, but used in Australia and New Zealand, would be perfectly safe for use in Sri Lanka too.
Sri Lanka has a deposit of phosphate minerals at Eppawala. While it is quite high in its arsenic contamination, it has very low cadmium contamination. Some people have urged the government to exploit the Eppawala deposits. I have opposed this as the conversion of the rock phosphate to usable TPS etc., is a highly polluting process that is best done far away from human habitations – i.e., unsuitable for Sri Lanka. In any case, a local production will also cost three to ten times more than what is available in the international market. Given the increasing scarcity of phosphate, the local deposit should be regarded as a national treasure that must be conserved for future use, until cleaner nano-technological methods for mineral exploitation become available.
Hence, I urge the government to change the cadmium and other heavy metal specifications used in Sri Lanka to conform to modern scientific knowledge, and align its standards with values used internationally. Having looked at the level of cadmium in Sri Lankan soils, I believe that an appropriate standard for Sri Lanka is to set its upper level for cadmium to be about 100-150 mg per kg of Phosphate, instead the current absurdly low value.

Disasters do not destroy nations; the refusal to change does
Sri Lanka has endured both kinds of catastrophe that a nation can face, those caused by nature and those created by human hands. A thirty-year civil war tore apart the social fabric, deepening mistrust between communities and leaving lasting psychological wounds, particularly among those who lived through displacement, loss, and fear. The 2004 tsunami, by contrast, arrived without warning, erasing entire coastal communities within minutes and reminding us of our vulnerability to forces beyond human control.
These two disasters posed the same question in different forms: did we learn, and did we change? After the war ended, did we invest seriously in repairing relationships between Sinhalese and Tamil communities, or did we equate peace with silence and infrastructure alone? Were collective efforts made to heal trauma and restore dignity, or were psychological wounds left to be carried privately, generation after generation? After the tsunami, did we fundamentally rethink how and where we build, how we plan settlements, and how we prepare for future risks, or did we rebuild quickly, gratefully, and then forget?
Years later, as Sri Lanka confronts economic collapse and climate-driven disasters, the uncomfortable truth emerges. we survived these catastrophes, but we did not allow them to transform us. Survival became the goal; change was postponed.
History offers rare moments when societies stand at a crossroads, able either to restore what was lost or to reimagine what could be built on stronger foundations. One such moment occurred in Lisbon in 1755. On 1 November 1755, Lisbon-one of the most prosperous cities in the world, was almost completely erased. A massive earthquake, estimated between magnitude 8.5 and 9.0, was followed by a tsunami and raging fires. Churches collapsed during Mass, tens of thousands died, and the royal court was left stunned. Clergy quickly declared the catastrophe a punishment from God, urging repentance rather than reconstruction.
One man refused to accept paralysis as destiny. Sebastião José de Carvalho e Melo, later known as the Marquês de Pombal, responded with cold clarity. His famous instruction, “Bury the dead and feed the living,” was not heartless; it was revolutionary. While others searched for divine meaning, Pombal focused on human responsibility. Relief efforts were organised immediately, disease was prevented, and plans for rebuilding began almost at once.
Pombal did not seek to restore medieval Lisbon. He saw its narrow streets and crumbling buildings as symbols of an outdated order. Under his leadership, Lisbon was rebuilt with wide avenues, rational urban planning, and some of the world’s earliest earthquake-resistant architecture. Moreover, his vision extended far beyond stone and mortar. He reformed trade, reduced dependence on colonial wealth, encouraged local industries, modernised education, and challenged the long-standing dominance of aristocracy and the Church. Lisbon became a living expression of Enlightenment values, reason, science, and progress.
Back in Sri Lanka, this failure is no longer a matter of opinion. it is documented evidence. An initial assessment by the United Nations Development Programme (UNDP) following Cyclone Ditwah revealed that more than half of those affected by flooding were already living in households facing multiple vulnerabilities before the cyclone struck, including unstable incomes, high debt, and limited capacity to cope with disasters (UNDP, 2025). The disaster did not create poverty; it magnified it. Physical damage was only the visible layer. Beneath it lay deep social and economic fragility, ensuring that for many communities, recovery would be slow, uneven, and uncertain.
The world today offers Sri Lanka another lesson Lisbon understood centuries ago: risk is systemic, and resilience cannot be improvised, it must be planned. Modern climate science shows that weather systems are deeply interconnected; rising ocean temperatures, changing wind patterns, and global emissions influence extreme weather far beyond their points of origin. Floods, landslides, and cyclones affecting Sri Lanka are no longer isolated events, but part of a broader climatic shift. Rebuilding without adapting construction methods, land-use planning, and infrastructure to these realities is not resilience, it is denial. In this context, resilience also depends on Sri Lanka’s willingness to learn from other countries, adopt proven technologies, and collaborate across borders, recognising that effective solutions to global risks cannot be developed in isolation.
A deeper problem is how we respond to disasters: we often explain destruction without seriously asking why it happened or how it could have been prevented. Time and again, devastation is framed through religion, fate, karma, or divine will. While faith can bring comfort in moments of loss, it cannot replace responsibility, foresight, or reform. After major disasters, public attention often focuses on stories of isolated religious statues or buildings that remain undamaged, interpreted as signs of protection or blessing, while far less attention is paid to understanding environmental exposure, construction quality, and settlement planning, the factors that determine survival. Similarly, when a single house survives a landslide, it is often described as a miracle rather than an opportunity to study soil conditions, building practices, and land-use decisions. While such interpretations may provide emotional reassurance, they risk obscuring the scientific understanding needed to reduce future loss.
The lesson from Lisbon is clear: rebuilding a nation requires the courage to question tradition, the discipline to act rationally, and leadership willing to choose long-term progress over short-term comfort. Until Sri Lanka learns to rebuild not only roads and buildings, but relationships, institutions, and ways of thinking, we will remain a country trapped in recovery, never truly reborn.

A wise Christmas
Important events in the Christian calendar are to be regurlarly reviewed if they are to impact on the lives of people and communities. This is certainly true of Christmas.
Community integrity
Years ago a modest rural community did exactly this, urging a pre-Christmas probe of the events around Jesus’ birth. From the outset, the wisemen aroused curiosity. Who were these visitors? Were they Jews? No. were they Christians? Of course not. As they probed the text, the representative character of those around the baby, became starkly clear. Apart from family, the local shepherds and the stabled animals, the only others present that first Christmas, were sages from distant religious cultures.
With time, the celebration of Christmas saw a sharp reversal. The church claimed exclusive ownership of an inclusive gift and deftly excluded ‘outsiders’ from full participation.
But the Biblical version of the ‘wise outsiders’ remained. It affirmed that the birth of Jesus inspired the wise to initiate a meeting space for diverse religious cultures, notwithstanding the long and ardous journey such initiatives entail. Far from exclusion, Jesus’ birth narratives, announced the real presence of the ‘outsider’ when the ‘Word became Flesh’.
The wise recognise the gift of life as an invitation to integrate sincere explanations of life; true religion. Religion gone bad, stalls these values and distorts history.
There is more to the visit of these sages.
Empire- When Jesus was born, Palestine was forcefully occcupied by the Roman empire. Then as now, empire did not take kindly to other persons or forces that promised dignity and well being. So, when rumours of a coming Kingdom of truth, justice and peace, associated with the new born baby reached the local empire agent, a self appointed king; he had to deliver. Information on the wherabouts of the baby would be diplomatically gleaned from the visiting sages.
But the sages did not only read the stars. They also read the signs of the times. Unlike the local religious authorities who cultivated dubious relations with a brutal regime hated by the people, the wise outsiders by-pass the waiting king.
The boycott of empire; refusal to co-operate with those who take what it wills, eliminate those it dislikes and dare those bullied to retaliate, is characteristic of the wise.
Gifts of the earth
A largely unanswered question has to do with the gifts offered by the wise. What happened to these gifts of the earth? Silent records allow context and reason to speak.
News of impending threats to the most vulnerable in the family received the urgent attention of his anxious parent-carers. Then as it is now, chances of survival under oppressive regimes, lay beyond borders. As if by anticipation, resources for the journey for asylum in neighbouring Egypt, had been provided by the wise. The parent-carers quietly out smart empire and save the saviour to be.
Wise carers consider the gifts of the earth as resources for life; its protection and nourishment. But, when plundered and hoarded, resources for all, become ‘wealth’ for a few; a condition that attempts to own the seas and the stars.
Wise choices
A wise christmas requires that the sages be brought into the centre of the discourse. This is how it was meant to be. These visitors did not turn up by chance. They were sent by the wisdom of the ages to highlight wise choices.
At the centre, the sages facilitate a preview of the prophetic wisdom of the man the baby becomes.The choice to appropriate this prophetic wisdom has ever since summed up Christmas for those unable to remain neutral when neighbour and nature are violated.
Wise carers
The wisdom of the sages also throws light on the life of our nation, hard pressed by the dual crises of debt repayment and post cyclonic reconstruction. In such unrelenting circumstances, those in civil governance take on an additional role as national carers.
The most humane priority of the national carer is to ensure the protection and dignity of the most vulnerable among us, immersed in crisis before the crises. Better opportunities, monitored and sustained through conversations are to gradually enhance the humanity of these equal citizens.
Nations in economic crises are nevertheless compelled to turn to global organisations like the IMF for direction and reconstruction. Since most who have been there, seldom stand on their own feet, wise national carers may not approach the negotiating table, uncritically. The suspicion, that such organisations eventually ‘grow’ ailing nations into feeder forces for empire economics, is not unfounded.
The recent cyclone gave us a nasty taste of these realities. Repeatedly declared a natural disaster, this is not the whole truth. Empire economics which indiscriminately vandalise our earth, had already set the stage for the ravage of our land and the loss of loved ones and possessions. As always, those affected first and most, were the least among us.
Unless we learn to manouvre our dealings for recovery wisely; mindful of our responsibilities by those relegated to the margins as well as the relentles violence and greed of empire, we are likely to end up drafted collaborators of the relentless havoc against neighbour and nature.
If on the other hand the recent and previous disasters are properly assessed by competent persons, reconstruction will be seen as yet another opportunity for stabilising content and integrated life styles for all Lankans, in some harmony with what is left of our dangerously threatened eco-system. We might then even stand up to empire and its wily agents, present everywhere. Who knows?
With peace and blessings to all!

Ranwala crash: Govt. lays bare its true face
The NPP government is apparently sinking into a pit dug by the one of its members, ‘Dr’ Asoka Ranwala; perhaps a golden pit (Ran Wala) staying true to his name! Some may accuse me of being unpatriotic by criticising a government facing the uphill task of rebuilding the country after an unprecedented catastrophe. Whilst respecting their sentiment, I cannot help but point out that it is the totally unwarranted actions of the government that is earning much warranted criticism, as well stated in the editorial “Smell of Power” (The Island, 15 December). Cartoonist Jeffrey, in his brilliance, has gone a step further by depicting Asoka Ranwala as a giant tsunami wave rushing to engulf the tiny NPP house in the shore, AKD is trying to protect. (The Island, 18 December).
The fact that Asoka Ranwala is very important to the JVP, for whatever reason, became evident when he was elected the Speaker of Parliament despite his lack of any parliamentary experience. When questions were raised about his doctorate in Parliament, Ranwala fiercely defended his position, ably supported by fellow MPs. When the Opposition kept on piling pressure, producing evidence to the contrary, Ranwala stepped aside, claiming that he had misplaced the certificate but would stage a comeback, once found. A year has passed and he is yet to procure a copy of the certificate, or even a confirmatory letter from the Japanese university!
The fact that AKD did not ask Ranwala to give up his parliamentary seat, a decision he may well be regretting now following recent events, shows that either AKD is not a strong leader who can be trusted to translate his words to action or that Ranwala is too important to be got rid of. In fact, AKD should have put his foot down, as it was revealed that Ranwala was a hypocrite, even if not a liar. Ranwala led the campaign to dismantle the private medical school set up by Dr Neville Fernando, which was earning foreign exchange for the country by recruiting foreign students, in addition to saving the outflow of funds for educating Sri Lankan medical graduates abroad. He headed the organisation of parents of state medical students, claiming that they would be adversely affected, and some of the photographs of the protests he led refer to him as Professor Ranwala! Whilst leading the battle against private medical education, Ranwala claims to have obtained his PhD from a private university in Japan. Is this not the height of hypocrisy?
The recent road traffic accident he was involved in would have been inconsequential had Ranwala been decent enough to leave his parliamentary seat or, at least, being humble enough to offer an apology for his exaggerated academic qualifications. After all, he is not the only person to have been caught in the act of embellishing a CV. As far as the road traffic accident is concerned, too, it may not be his entire responsibility. Considering the chaotic traffic, in and around Colombo, coupled with awful driving standards dictated by lack of patience and consideration, it is a surprise that more accidents do not happen in Sri Lanka. Following the accident, may be to exonerate from the first count, a campaign was launched by NPP supporters stating that a man should be judged on his achievements, not qualifications, further implying that he does not have the certificate because he got it in a different name!
What went wrong was not the accident, but the way it was handled. Onlookers claim that Ranwala was smelling of alcohol but there is no proof yet. He could have admitted it even if he had taken any alcohol, which many do and continue to drive in Sri Lanka. After all, the Secretary to the Ministry overseeing the Police was able to get the charge dropped after causing multiple accidents while driving under the influence of liquor! He, with another former police officer, sensing the way the wind was blowing formed a retired police collective to support the NPP and were adequately rewarded by being given top jobs, despite a cloud hanging over them of neglect of duty during the Easter Sunday attacks. This naïve political act brought the integrity of the police into question. The way the police behaved after Ranwala’s accident confirmed the fears in the minds of right-thinking Sri Lankans.
In the euphoria of the success of a party promising a new dawn, unfortunately, many political commentators kept silent but it is becoming pretty obvious that most are awaking to the reality of a false dawn. It could not have come at a worse time for the NPP: in spite of the initial failures to act on the warnings regarding the devastating effects of Ditwah, the government was making good progress in sorting problems out, when Ranwala met with an accident.
The excuses given by the police for not doing a breathalyser test, or blood alcohol levels, promptly, are simply pathetic. Half-life of alcohol is around 4-5 hours and unless Ranwala was dead drunk, it is extremely unlikely any significant amounts of alcohol would be detected in a blood sample taken after 24 hours. Maybe the knowledge of this that made government Spokesmen to claim boldly that proper action would be taken irrespective of the position held. Now that the Government Analyst has not found any alcohol in the blood, no action is needed! Instead, the government seems to have got the IGP to investigate the police. Would any police officers suffer for doing a favour to the government? That is the million-dollar question!
Unfortunately, all this woke up a sleeping giant; a problem that the government hoped would be solved by the passage of time. If the government is hoping that the dishonesty of one of its prominent members would be forgotten with the passage of time, it will be in for a rude shock. When questioned by journalists repeated, the Cabinet spokesman had to say action would be taken if the claim of the doctorate was false. However, he added that the party has not decided what that action would be! What about the promise to rid Parliament of crooks?
It is now clear that the NPP government is not any different from the predecessors and that Sri Lankan voters are forced to contend with yet another false dawn!
