Limit number of vehicles per family to curb air pollution, say experts

Rise in air pollution is linked to growing respiratory ailments in India, experts have said and urged the government to bring a policy limiting the number of cars per family and restricting the number of vehicles plying on roads at a time. On the sidelines of the 25th National Conference on Pulmonary Diseases (NAPCON-2023), organised by the Indian Chest Society here, Dr Rakesh K Chawla, the chairman of Pulmonology and Critical Care at Jaipur Golden Hospital, said air pollution has short-term as well as long-term effects on health. "The immediate effects are in the form of irritation in the eyes and throat. Also, there is an increase in the severity of asthma attacks," said Dr Chawla, who is also the organising chairman of NAPCON-2023. The conference was organised to discuss air pollution and diseases caused by it as well as the advancements in the field of pulmonology. Dr Chawla said the long-term effects of air pollution include respiratory diseases and lung cancer, and the worst

Illegal dyeing units in Delhi: NGT seeks report within 5 weeks from DPCC

The National Green Tribunal has sought a "fresh report" within five weeks from the Delhi Pollution Control Committee regarding the illegal operation of several dyeing units in the national capital. The tribunal was hearing a petition, which alleged that dyeing units in Bindapur, Matiala, Ranhola, Khyala, Meethapur, Badarpur, Mukundpur and Kirar are violating provisions of the Water (Prevention and Control of Pollution) Act and the Air (Prevention and Control of Pollution) Act. A bench of Chairperson Justice Prakash Shrivastava noted the report of an earlier panel and said most of the dyeing units were not inspected on the plea that they were found to be locked. The bench noted the Delhi Pollution Control Committee counsel's submission that inspection teams visited 50 of the total 70 dyeing units. However, as several of these factories were found to be locked, these required re-inspection. The tribunal, in an order passed on October 4, noted that the committee's counsel had sought f

Delhi most polluted city in past year, Mizoram sustains cleanest air: Study

Although its air quality improved marginally, Delhi remained the most polluted city in the year ending September 30, with a PM2.5 concentration of 100.1 micrograms per cubic metre, which is three times the government's safe limit, according to a new analysis. The analysis conducted by independent think tank Climate Trends and tech firm Respirer Living Sciences, that manufactures real-time IoT-based air quality monitoring devices, showed that Aizawl and Mizoram have India's cleanest air with a PM2.5 level of only 11.1 micrograms per cubic metre. Four more cities from the National Capital Region -- Faridabad (89 micrograms per cubic metre), Noida (79.1 micrograms per cubic metre), Ghaziabad (78.3 micrograms per cubic metre) and Meerut (76.9 micrograms per cubic metre) -- also feature among the top 10 most polluted cities. The report is based on the analysis of the government's PM2.5 data from October 1, 2022, to September 30, 2023, and focuses on the cities covered under the National

Nanoparticle emissions from vehicles in Delhi pose health risks: Study

Delhi has been experiencing hazardous levels of nanoparticles in urban air, especially in the roadside environment, directly related to vehicular engine exhaust, raising pubic health concerns, according to a study. Nanoparticles are minuscule particles, often measuring between 10 to 1000 nanometers (nm) in diameter, making them invisible to the naked eye. These particles are more dangerous to human health due to their much smaller size compared to PM 2.5 or PM 10. Being 600 times smaller than a human hair, they can penetrate deep into our lungs, bloodstream, and even the brain. The study, published in the journal Urban Climate, was conducted on Bawana Road in northwest Delhi, connecting Delhi to Rohtak in Haryana. The monitoring location is surrounded by educational institutions, households, and commercial areas where the dominant source of pollution is vehicular, the researchers said. Other sources include biomass burning, fuel used for residential heating in winter, and firework

Centre's action plan to check air pollution in Delhi takes effect

The Graded Response Action Plan -- a set of anti-air pollution measures implemented in Delhi-NCR during the winter -- came into effect on Sunday. The Commission for Air Quality Management (CAQM), an autonomous body tasked with improving the air quality in Delhi and its adjoining areas, made crucial changes to the Graded Response Action Plan (GRAP) last year and again in July. The new changes include strict restrictions on the plying of overage vehicles and a complete ban on the use of coal and firewood in eateries, restaurants and hotels when the Air Quality Index (AQI) breaches the 200-mark. BS-III petrol and BS-IV diesel four-wheelers will be immediately banned in Delhi and Gurugram, Faridabad, Ghaziabad and Gautam Buddh Nagar if the AQI crosses the 400-mark. The CAQM, a statutory body formed under an Act in 2021, amended the GRAP in 2022 to ensure proactive implementation of anti-air pollution steps based on forecasts up to three days in advance. Earlier, the authorities would

Delhi residents on track to lose 11.9 years of life to pollution: Study

Delhi has emerged as the world's most polluted city in a new study which has also found that its residents are on track to lose 11.9 years of life if the current levels of pollution persist. The Air Quality Life Index (AQLI) released by the Energy Policy Institute at the University of Chicago also showed that all of India's 1.3 billion people live in areas where the annual average particulate pollution level exceeds the 5 g/m3 limit set by World Health Organization (WHO). It also found that 67.4 per cent of the country's population lives in areas that exceed the country's own national air quality standard of 40 g/m3. The study said fine particulate air pollution (PM2.5) shortens an average Indian's life expectancy by 5.3 years, relative to what it would be if the 5 g/m3 pollution limit set by (WHO) was met. The AQLI said that Delhi is the most polluted city in the world with its 18 million residents on track to lose 11.9 years of life expectancy on average relative to the WHO limit

Yamuna shows signs of improvement with dip in biochemical oxygen demand

The BOD levels in the Najafgarh drain here have reduced by 33 per cent compared to last year, improving the overall health of the Yamuna river, according to Delhi Pollution Control Committee (DPCC) data. The drain accounts for around 70 per cent of the wastewater being discharged into the Yamuna. Biochemical oxygen demand (BOD), an important parameter to assess water quality, is the amount of oxygen required by aerobic microorganisms to decompose organic material present in a water body. A BOD level of less than 3 milligrams per litre is considered good. The DPCC data was shared during a high-level committee meeting headed by Lieutenant Governor V K Saxena on Friday. According to a statement from the LG secretariat, a month-wise comparison of the DPCC data shows a "consistent improvement" in the water quality of the Najafgarh drain and the Yamuna. The DPCC data showed the BOD level in the Najafgarh drain this January was 53 mg/l, an improvement from 80 mg/l recorded in January las
