Delhiites more exposed to black carbon than Americans

London, Jul 11: Travelling by car in Delhi exposes people to black carbon levels five times higher than Europe and America, say scientists who found that Asian residents are exposed to nine times more air pollution than their Western counterparts.

According to the World Health Organisation (WHO), about 88 per cent of premature deaths in low- and middle-income countries in Asia can be attributed to air pollution.

The number of road vehicles in Beijing increased from 1.5 million in 2000 to more than 5 million in 2014 and the number in Delhi is expected to increase from 4.7 million in 2010 to 25.6 million by 2030.

In a study published in the journal Atmospheric Environment, researchers looked at studies of pollution exposure and concentration levels in Asian transport microenvironments (walking, driving, cycling, motorbike riding and bus riding).

Researchers from the University of Surrey in the UK focused on the levels of fine particles, black carbon produced by carbon-rich fuels such as gasoline and diesel fuel, and ultrafine particles (UFP) small enough to travel deep into a citizen's lungs.

The study found evidence that pedestrians walking along busy roadsides in Asian cities are exposed to up to 1.6 times higher fine particle levels than people in European and American cities.

Car drivers in Asia are exposed to up to nine times more pollution than Europeans and Americans, while black carbon levels were seven times higher for Asian pedestrians than Americans.

The study reported that in Hong Kong, UFP levels were up to four times higher than in cities in Europe. In New Delhi, average black carbon concentration in cars was up to five times higher compared to Europe or North America.

"Care should be taken in directly comparing and contrasting the results of different studies due to varying amounts of information available on personal exposure in studied regions," said Prashant Kumar, Director of the Global Centre for Clean Air Research at the University of Surrey.

However, there is compelling evidence that people travelling in urban areas in Asian cities are being exposed to a significantly higher level of air pollution.

"A noticeable gap still exists in studies that focus on the Asian population living in rural, semi-rural or smaller cities, where pollution exposure could be as harmful as in urban areas owing to several unattended sources," said Kumar.

"There were rare data on cyclist and motorcyclist exposure despite substantial use in Asian cities; studies were limited for other transport modes too," he said.

"It is important that this knowledge gap is filled if we are to get a complete picture of the pollution exposure challenge that the Asian population faces," he added.

"There are increasing efforts in Asia to install properly designed and calibrated portable monitoring systems to measure actual exposures, using the data to better understand why high exposures occur and how to prevent them," said Chris Frey of North Carolina State University in the US.

"These measurements of personal exposures will help individuals, businesses, and governments to develop and implement strategies to reduce such exposures," said Frey.

New Delhi: School-going children are picking up drug and smoking habits and engaging in consumption of alcohol, with the average age of introduction to such harmful substances found to be around 13 years, suggesting a need for earlier interventions as early as primary school, a multi-city survey by AIIMS-Delhi said.

The findings also showed substance use increased in higher grades, with grade XI/XII students two times more likely to report use of substances when compared with grade VIII students. This emphasised the importance of continued prevention and intervention through middle and high school.

The study led by Dr Anju Dhawan of AIIMS's National Drug Dependence Treatment Centre, published in the National Medical Journal of India this month, looks at adolescent substance use across diverse regions.

The survey included 5,920 students from classes 8, 9, 11 and 12 in urban government, private and rural schools across 10 cities -- Bengaluru, Chandigarh, Delhi, Dibrugarh, Hyderabad, Imphal, Jammu, Lucknow, Mumbai, and Ranchi. The data were collected between May 2018 and June 2019.

The average age of initiation for any substance was 12.9 (2.8) years. It was lowest for inhalants (11.3 years) followed by heroin (12.3 years) and opioid pharmaceuticals (without prescription; 12.5 years).

Overall, 15.1 per cent of participants reported lifetime use, 10.3 per cent reported past year use, and 7.2 per cent reported use in the past month of any substance, the study found.

The most common substances used in the past year, after tobacco (4 per cent) and alcohol (3.8 per cent), were opioids (2.8 per cent), followed by cannabis (2 per cent) and inhalants (1.9 per cent). Use of non-prescribed pharmaceutical opioids was most common among opioid users (90.2 per cent).

On being asked, 'Do you think this substance is easily available for a person of your age' separately for each substance category, nearly half the students (46.3 per cent) endorsed that tobacco products and more than one-third of the students (36.5 per cent) agreed that a person of their age can easily procure alcohol products.

Similarly, for Bhang (21.9 per cent), ganja/charas (16.1 per cent), inhalants (15.2 per cent), sedatives (13.7 per cent), opium and heroin (10 per cent each), the students endorsed that these can be easily procured.

About 95 per cent of the children, irrespective of their grade, agreed with the statement that 'drug use is harmful'.

The rates of substance use (any) among boys were significantly higher than those of girls for substance use (ever), use in the past year and use in the past 30 days. Compared to grade VIII students, grade IX students were more likely, and grade XI/XII students were twice as likely to have used any substance (ever).

The likelihood of past-year use of any substance was also higher for grade IX students and for grade XI/XII students as compared to grade VIII students.

About 40 per cent of students mentioned that they had a family member who used tobacco or alcohol each. The use of cannabis (any product) and opioid (any product) by a family member was reported by 8.2 per cent and 3.9 per cent of students, respectively, while the use of other substances, such as inhalants/sedatives by family was 2-3 per cent, the study found.

A relatively smaller percentage of students reported use of tobacco or alcohol among peers as compared to among family members, while a higher percentage reported inhalants, sedatives, cannabis or opioid use among peers.

Children using substances (past year) compared to non-users reported significantly higher any substance use by their family members and peers.

There were 25.7 per cent students who replied 'yes' to the question 'conflicts/fights often occur in your family'. Most students also replied affirmatively to 'family members are aware of how their time is being spent' and 'damily members are aware of with whom they spend their time'.

Invoking the teachings of Prophet Muhammad—“pay the worker before his sweat dries”—the Madras High Court has directed a municipal corporation to settle long-pending legal dues owed to a former counsel. The court observed that this principle reflects basic fairness and applies equally to labour and service-related disputes.

Justice G. R. Swaminathan made the observation while hearing a petition filed by advocate P. Thirumalai, who claimed that the Madurai City Municipal Corporation failed to pay him legal fees amounting to ₹13.05 lakh. Earlier, the High Court had asked the corporation to consider his representation. However, a later order rejected a major portion of his claim, prompting the present petition.

The court allowed Thirumalai to approach the District Legal Services Authority (DLSA) and submit a list of cases in which he had appeared. It also directed the corporation to settle the verified fee bills within two months, without interest. The court noted that the petitioner had waited nearly 18 years before challenging the non-payment and that the corporation could not be fully blamed, as the fee bills were not submitted properly.

‘A Matter of Embarrassment’

Justice Swaminathan described it as a “matter of embarrassment” that the State has nearly a dozen Additional Advocate Generals. He observed that appointing too many law officers often leads to unnecessary allocation of work and frequent adjournments, as government counsel claim that senior officers are engaged elsewhere.

He expressed hope that such practices would end at least in the Madurai Bench of the High Court and added that Additional Advocate Generals should “turn a new leaf” from 2026 onwards.

‘Scandalously High Amounts’

While stating that the court cannot examine the exact fees paid to senior counsel or law officers, Justice Swaminathan stressed that good governance requires public funds to be used prudently. He expressed concern over the “scandalously high amounts” paid by government and quasi-government bodies to a few favoured law officers.

In contrast, the court noted that Thirumalai’s total claim was “a pittance” considering the large number of cases he had handled.

Background

Thirumalai served as the standing counsel for the Madurai City Municipal Corporation for more than 14 years, from 1992 to 2006. During this period, he represented the corporation in about 818 cases before the Madurai District Courts.

As the former counsel was unable to hire a clerk to obtain certified copies of judgments in all 818 cases, the court directed the District Legal Services Authority to collect the certified copies within two months. The court further ordered the corporation to bear the cost incurred by the DLSA and deduct that amount from the final settlement payable to the petitioner.

Mangaluru: Public transport in Mangaluru is set for a state-led transformation as the government moves to deploy 100 new electric govt buses to replace unreliable private services. The initiative aims to provide a dependable alternative to private operators who have been frequently "cutting trips," leaving thousands of commuters stranded.

The announcement was made by Deputy Commissioner and MCC Administrator Darshan HV during a public phone-in session. The move specifically targets routes where private bus service has become erratic, ensuring that citizens no longer have to rely on a fluctuating private sector for their daily commute.

Restoring the Govt Presence

The transport crisis was brought to the forefront by Ramayya, a resident of Bajal, who highlighted a growing trend of private buses skipping morning and night trips. With the previous KSRTC (govt) services discontinued, residents have been left without a fallback option.

To fix this, the DC confirmed that the PM-eBus Sewa Scheme will bring 100 government-owned electric buses to the city:

•    Phased Deployment: The first 50 of the new 100 government buses are scheduled to arrive by March 2026.

•    State Infrastructure: Two new government depots, including one at Mudipu, are being prepared for operations.

•    Recruitment: The state has already begun training a new batch of government bus drivers to ensure the fleet is operational the moment it arrives.
