Rising air pollution levels threaten health

Published

on

Public concern is increasing about the high levels of air pollution in Sri Lanka, where the air is described as unhealthy for the general population. This assessment is based on the air quality data expressed as an Air Quality Index for a number of cities of Sri Lanka. Just three days ago, Jaffna recorded the highest degree of air pollution with a value of 294, followed by Kurunegala, Anuradhapura, Kandy and Colombo. From November onwards, air quality levels in Colombo have exceeded the 150 value (which is considered as the safe level) and which can be classified as “unhealthy”. By contrast, New Delhi, which has the highest level of air pollution in the world, typically has values of around 350 and the air is classified as “hazardous”.

These values are based on the levels of fine particles, which we call PM2.5, composed of particles with a diameter less than 2.5 microns. A micron is one millionth of a metre and such small particles are invisible to the naked eye. They are generated primarily from motor vehicle exhaust fumes, industrial activities, biomass burning and coal burning power plants. In India, the ever increasing number of motor vehicles, traffic congestion, are the contributing factors; and the air pollution level further deteriorates every fall, as farmers in nearby states burn crop stubble to prepare fields for the next planting season. These pollution clouds generated in India can travel thousands of kilometres to Sri Lanka during the north-east (NE) monsoon. This is what is referred to as transboundary air pollution.

My own research carried out from 1996-2003, showed that acid rain occurs in places like Anuradhapura and Mahailluppalama during the NE monsoon. We were not able to get any data for Jaffna at that time owing to the war situation. These results are further confirmed by the current air pollution episodes, where Jaffna recorded the highest values on certain days earlier this week. Jaffna, which is the major city closest to India, gets a high dose of pollution from the Indian subcontinent. The highest recorded value in Jaffna on December 6th was 294, while it was 220 in Colombo and 262 in Kandy. These values are in a very unhealthy region.

When we breathe air particles enter our respiratory system. Out of these, the larger particles are filtered due to movement of hair and cilia along the upper respiratory tract, but particles with diameters less than 10 microns (PM10) enter the lung, where they get lodged to the alveolar tissues of the lung. Particles disrupt the protective mucus layer of the alveolar tissues, and viruses and bacteria can readily enter the respiratory system through the ruptured mucus. Much smaller particles such as the PM2.5 can even enter the bloodstream. Particles in the category of PM10 cause blood vessel narrowing, increases stickiness of blood, increases clot formation and makes the heart beat irregularly. This results in an increase of the risk of coronary heart disease, and a previous study by the WHO reported that around 8000 deaths due to heart diseases are due to air pollution in Sri Lanka.

Particles are considered as the most dangerous air pollutant. Fine carbon particles, in addition, have polyaromatic compounds such as carcinogenic benzopyrenes attached to them, and since these are well known to cause cancer and prolonged exposure may cause lung cancer. These can lead to respiratory diseases such as bronchitis, pneumonia, chronic obstructive pulmonary disease and exacerbate asthma. Other milder symptoms such as sore throat and breathing difficulties may also appear.

Air quality data, taken from December 6th till now, indicate that air pollution is high in relatively less congested places like Hambantota and Mullativu. Local traffic and other pollution sources are minimal in these two towns and transboundary air pollution has made the air unhealthy. Therefore, it is essential for the authorities to regularly inform the public on the degree of air pollution for all localities of Sri Lanka. My own research several years ago confirmed that Kandy is far more polluted than Colombo, and a lot of people were sceptical about my proposition at that time; but the current data indicate that on several occasions AQI for Kandy exceeded that of Colombo.

The current unhealthy trend in air quality is likely to continue till February next year, which is the end of the north-east monsoon. People should wear face masks whenever they move out of the house, and doors and windows kept closed at all times. Vigorous exercise and outdoor activities such as walking and jogging should be avoided. Transboundary air pollution is a global phenomenon, and while we have signed the Male declaration on the prevention of transboundary air pollution in south-east Asia, no effective action has been taken by any of the signatories to this declaration.

Is AKD following LKY?

Published

on

by Chula Goonasekera
Rev. Dato’ (Sir) Sumana Siri

We, the citizens of Sri Lanka, have already witnessed significant reforms in governance under AKD’s leadership. This personally led process must continue consistently, free of bias, and within the framework of the law to ensure sustainable governance by the State, not the individual. Such efforts will help minimise the waste of public funds and lay a strong foundation for the nation’s development in the long term. We often look to Lee Kuan Yew (LKY), Singapore’s founding father, as an example of transformative leadership. He united three diverse ethnic groups—Chinese, Malay, and Indian—under the principle of honesty. Today, Sri Lanka faces profound challenges from past political corruption, economic instability, and social divisions. LKY’s leadership serves as a reminder that integrity, accountability, and a commitment to the greater good can redefine a nation’s destiny, regardless of its size or resources, similar to Singapore.

When Singapore gained independence in 1965, it was a small, resource-scarce nation facing political unrest and ethnic divisions. Yet, within one generation, it became a global financial hub and a first-world country. LKY’s leadership was pivotal, centred on three core principles: meritocracy, integrity, and pragmatic governance. He prioritised national security, social cohesion, and economic growth. His efforts to foster ethnic harmony included implementing bilingual education policies and enforcing anti-discrimination laws. Similarly, AKD should consider enacting legislation to prevent racially motivated demands, i.e. anti-discrimination laws, to safeguard the government from evil, selfish minds trying to destabilise the government’s commitment to equality. Such legislation will stop this burden falling on the leadership case by case.

LKY’s policies, though sometimes harsh, were rooted in practicality and long-term thinking. The Internal Security Act ensured peace and stability during critical years. Likewise, his investments in education and infrastructure established a foundation for sustained growth. His focus on political stability, a robust legal system, and zero tolerance for corruption inspired investor confidence. Singapore’s Corrupt Practices Investigation Bureau (CPIB) was empowered to tackle corruption at all levels. Sri Lanka must adopt a similar mindset to revitalise the Bribery and Corruption Commission, moving away from populism and short-term fixes in favour of strategic, future-oriented policies.

AKD’s primary election theme was anti-corruption, reflecting a key aspect of LKY’s leadership. His unwavering stance against corruption defined LKY’s pragmatic governance. He held public officials to the highest accountability standards, ensuring that anyone guilty of corruption faced severe consequences, including dismissal, public exposure, and prosecution. By rooting out corruption, Singapore built domestic credibility and attracted global investment. We in Sri Lanka need such legislation at the earliest opportunity to deal with various kinds of corruption that are appearing again and involving many public officials.

In Sri Lanka, corruption has long undermined public trust in institutions and stifled economic growth. With overwhelming public support, AKD is well-positioned to deliver on his promise to combat corruption. However, this needs to be done early before the government gets entangled with controversy over its own ‘tiered’ standards. Through comprehensive legislative measures, Sri Lanka can rebuild its institutions, restore public confidence, and chart a course toward sustainable development.

LKY was considered “cruel” by some because he treated all races equally without favouring any. AKD shares a similar stance. One of the hallmarks of LKY’s leadership was his unwavering commitment to meritocracy. This created a culture of excellence where the best and brightest minds were responsible for leading the country. In Singapore, recruitment and promotions across all sectors were strictly based on merit—capabilities, skill sets, and abilities—not on connections, nepotism, racial considerations, or personal favouritism. Although challenging to implement, meritocracy can be implemented with the open advertisement of qualifications needed, a transparent appointment process, strict job plans with annual reviews linked to customer feedback, and personal development strategies that are considered a necessity to continue. This approach will foster a culture of excellence and innovation, like Singapore, ensuring that the most capable individuals propel the country forward.

Sri Lanka must break free from the grip of favouritism and focus on nurturing talent through equal opportunities for all citizens, regardless of ethnicity or social background. Early signs of this approach are visible under AKD’s leadership. LKY understood that for a nation to progress, its institutions must be led by those who are truly capable, irrespective of their background. By adopting meritocracy, Sri Lanka could break the cycle of favouritism, nepotism, and ethnic division that has often hindered its development. Establishing a system where opportunities are based on ability and performance could unlock the full potential of Sri Lanka’s people, fostering a culture of innovation, growth, and national unity.

After gaining independence in 1965, during Singapore’s formative years, LKY focused on eliminating corruption, gang activities, and communist threats to create a peaceful and secure nation. The Internal Security Act (ISA) granted his administration discretionary powers to arrest and detain individuals without trial, when necessary, to prevent actions deemed harmful to Singapore’s security, public order, or essential services.

The ISA allowed preventive detention, suppression of subversion, and countering of organised violence against persons and property. Sri Lanka urgently needs a similar act to ensure that politicians and public officials comply with legally binding measures. With its Parliament still in its formative stages, we hope Sri Lanka will soon establish a comparable Internal Security Act. By eliminating corruption at all levels, as LKY did, Sri Lanka can inspire public trust and attract international investors who view stability and a corruption-free environment as prerequisites for investment. This approach could transform Sri Lanka into a manufacturing, business, and financial hub for the Indian Ocean region.

Under LKY’s leadership—often described as strict—Singapore transformed from a third-world nation into a first-world country. Sri Lanka has the potential to achieve even more, given its abundant natural resources, strategic location, and educated population that can be developed into a skilled workforce. With its prime position in the Indian Ocean, Sri Lanka could become a regional economic powerhouse—provided it fosters a stable and investor-friendly environment. Like Singapore, Sri Lanka should adhere to a non-aligned foreign policy to emerge as a crucial node in global trade and finance, maintaining friendly ties with Eastern, Western, and Asian powers while leveraging its strategic location.

While some label LKY’s methods as “cruel,” his leadership was not about oppression but discipline and fairness. Whether these policies were “cruel” or benevolent is debatable, but their results speak for themselves. He treated all races equally, fostering harmony in a diverse society by ensuring everyone felt they had a stake in Singapore’s future. Moreover, LKY’s economic policies were marked by simplicity and foresight. Low personal income taxes, the absence of capital gains and inheritance taxes, and a business-friendly environment encouraged reinvestment and entrepreneurship. By positioning Singapore as a global trade and financial hub, LKY ensured its economic resilience. Sri Lanka, too, must prioritise national unity. Divisive politics and ethnic biases must be curtailed to build a shared vision of prosperity and peace, as AKD is striving to do.

LKY’s leadership was built on three core tenets relevant to Sri Lanka today: meritocracy, integrity, and pragmatism. Encouragingly, AKD appears to be moving in a similar direction. One of LKY’s greatest strengths was his pragmatic, long-term approach to governance. He maintained tight control over domestic finances, preventing the internationalisation of the Singapore dollar and limiting the operations of foreign banks. This created an environment that attracted international firms eager to establish themselves in Singapore. Sound financial policies, a corruption-free environment, and a focus on technological advancement helped Singapore become a hub for multinational companies like General Electric. State-owned enterprises like Temasek Holdings and Singapore Airlines were run with business efficiency, often outperforming private sector competitors. Sri Lanka could adopt a similar model to enhance the performance of its state-owned enterprises and boost economic growth.

Singapore adopted a two-pronged financial strategy: becoming an international financial hub while ensuring its financial sector supported key domestic industries like manufacturing and shipping. Additionally, integrating foreign and local talent fuelled decades of sustained economic growth. LKY’s focus on economic development, making Singapore an attractive investment destination, and drawing world-class manpower offer valuable lessons for Sri Lanka.

To replicate such success, Sri Lanka must invest in state-of-the-art infrastructure, establish excellent air and sea linkages, and maintain a low and transparent tax regime.

Clean and efficient bureaucracy, a strong regulatory and legal framework, and a neutral diplomatic policy—balancing relations with global powers like the US and China—are critical. Developing clean, green cities powered by sustainable energy will also be key to achieving remarkable economic success akin to Singapore’s.

‘A degree is not a title’ – a response

Published

on

Reference the above-captioned letter in The Island of 16 Decembe, its writer, Philosophiae Doctor (PD), he is incorrect in his analysis of a Ph. D degree as a title. As Dr. Upul Wijewardena has said, only a Ph. D holder who can use the title ‘Dr’. However, the tradition is for those who have a medical degree to be called Dr. PD has written about the history of universities and quoted chapter and verse about the origin of degrees. We are now in the twenty first century and most universities have their own system of awarding Ph. Ds. For instance, British universities award Ph. Ds based on 100 per cent research whereas in American universities Ph. D degrees are awarded on the basis of 50 per cent research and 50 per cent course work. The research degree is given more weight at interviews.

PD has also said that a Masters’ Degree (MA) is essential to teach in a university.  Many universities including universities in Sri Lanka offer Assistant Lecturer positions to those who have first degrees with classes. Some time ago, the Dean of the faculty of Arts at Otago university, New Zealand had only a B.A. He was appointed Professor because of his publications. In American universities lecturers with a Ph. D are addressed as Assistant Professor. Then a Professor after retirement has to get permission from his university to use the title as Professor (Emeritus). There is no such requirement for a person with a Ph. D to use the title Dr.  Modern universities do not follow procedures that were adopted in old Europe mentioned by PD.

Electricity tariffs cannot be reduced due to CEB Mafia

Published

on

Ceylon Electricity Board (CEB) has apparently become a law unto itself; it is increasing the salaries and other perks for senior staff at their will. There are 26,131 employees of CEB and its monthly salary bill is around Rs. 3,000 million, out of which 600 million goes for the salaries of engineers. A special grade engineer’s monthly take-home salary is reportedly about Rs. 919, 432 while an E1 grade engineer draws around Rs. 694,240 a month. These include a vehicle allowance of Rs. 250,000 and other benefits. The CEB has thought it is fit to regularly increase the salaries at the insistence of the powerful engineers’ union every three years without getting the approval of the cabinet or the public accounts committee of the finance ministry.

Out of the total number of employees at least 50% are political appointees recrutied by successive ministers of the power and energy ministry. Even the salary of a meter reader is Rs. 54,420 and it comes to around Rs. 125,000 a month. This is far higher and about 100% more than a graduate teacher. With such an excessive workforce earning exorbitant salaries no wonder that the CEB cannot reduce the electricity bills of consumers. There are 6.29 employees for every megawatt (MW) of power generated by CEB while the Malaysian Electricity Board generates six times more power and has only 1.15 employees for one MW of power generated!

PAYE tax should be borne by the employee and it is against the Inland Revenue Act for an institution to pay the PAYE tax due from its employees.  It has been revealed before the COPE (the Committee on Public Enterprises) that Rs. 5 billion has been paid by the CEB as PAYE tax to its employees during the period 2010-2019 in contravention of a Cabinet decision on 13 December 2007. This, the CEB has been doing at the expense of consumers, who have to pay higher tariffs.

Verite Research has revealed that Sri Lankan households pay 2.5 to 3 times more for electricity than the average cost to their counterparts in South Asian countries. Our rates are much higher than in Bangladesh and Afghanistan. For instance, a consumer using 300 units of electricity has to pay an electricity bill of Rs. 21,860 while the average equivalent rate in South Asia is only Rs. 7,340. This shows how our professional engineers have managed the CEB power generation so inefficiently over the years.

 The reason for this inefficiency is due to the neglect of renewable energies in Sri Lanka. The CEB engineers have always advocated for more and more coal-powered plants. They have deliberately blocked renewable energy projects for obvious reasons.  The Supreme Court has found the CEB guilty of blocking a proposal by Vavuniya Solar Power Private limited for a solar energy plant and ordered it to pay Rs 01 million rupees as damages. This, too, would have been paid from CEB funds and those who took such corrupt decisions have got off scot-free. The technical officers of CEB allege that CEB management has purchased power from private power plants despite an increase in hydro power generation. In case hydropower is insufficient to meet the demand another idling turbine at Norochcholai could have been put into operation. There are serious allegations that CEB engineers are intimately connected to such private power plants and even own all or part of them. The new government should appoint an independent commission to investigate allegations against the CEB.
