The primary extreme smog episode has hit Delhi and the Nationwide Capital Area (NCR) and is predicted to final for an additional two days, inexperienced think-tank Centre for Science and Surroundings (CSE) stated right this moment. Regardless that the seasonal smog in Delhi is intense, the common every day contribution of smoke from farm fires from the center of October to November eight has been the bottom in final 4 years, it stated. “Predictably, the season’s first episode has been triggered by the mixed impact of unfavourable climate situations (cool and calm winds and inversion), stubble burning and firecrackers,” stated Anumita Roychowdhury, government director, analysis and advocacy, CSE. In comparison with the primary smog episode of earlier 4 years, the present smog has matched the period of the primary smog of 2018 and 2020 season — each lasted six days. If situations do not enhance, it would overtake the 2019 smog that lasted eight days, the CSE stated. The common depth of the smog this 12 months to this point is 329 microgram per cubic metre per day, which is decrease than that of the 2020 smog (by 7 per cent) and 2019 smog (by three per cent). It’s extra intense than the 2018 smog (about 9 per cent). Lingering on of this 12 months’s smog for longer period regardless of comparatively windier native situations may be because of the lack of air pollution management measures within the metropolis, the inexperienced assume tank stated. “Whereas very excessive concentrations of PM2.5 have hogged consideration, the degrees of gases – ozone, CO or NO2 — have remained elevated throughout this smog episode. Additionally, the ratio of SO2 to NO2 elevated on Diwali evening indicating elevated air pollution load from firecrackers. The PM2.5 focus on Diwali evening (eight pm to eight am) has been probably the most intense since 2017,” stated Avikal Somvanshi, programme supervisor, City Lab, CSE. This evaluation is predicated on the actual time knowledge out there from the present working air high quality monitoring stations in Delhi-NCR and the bigger Indo-Gangetic Plain. “On a median, contribution of smoke to Delhi’s every day PM2.5 throughout center of October to November eight has been the bottom within the final 4 years. Thus far, it has recorded on a median 12 per cent per day in distinction to 17 per cent per day in 2020, 14 per cent per day in 2019, and 16 per cent per day in 2018 (as reported by SAFAR),” the CSE stated. “If transformed to absolute concentrations, the per day contribution of smoke stood at 26 microgram per cubic metre this 12 months to this point in comparison with 35 microgram per cubic metre in 2020, 40 microgram per cubic metre in 2019, and 31 microgram per cubic metre in 2018,” it stated. Nonetheless, the height contribution of smoke to Delhi’s PM degree was recorded on seventh November when it hit 48 per cent. This the second highest every day contribution proportion recorded since such estimation was began by SAFAR in 2018. The best single day contribution proportion has been 58 per cent recorded on November 5, 2018.

Delhi in grip of season"s first smog episode, likely to be longest in 4 yrs: CSE

The first severe smog episode has hit Delhi and the National Capital Region (NCR) and is expected to last for another two days, green think-tank Centre for Science and Environment (CSE) said on Wednesday. Even though the seasonal smog in Delhi is intense, the average daily contribution of smoke from farm fires from the middle of October to November 8 has been the lowest in last four years, it said. “Predictably, the season"s first episode has been triggered by the combined effect of unfavourable weather conditions (cool and calm winds and inversion), stubble burning and firecrackers,” said Anumita Roychowdhury, executive director, research and advocacy, CSE. Compared to the first smog episode of previous four years, the current smog has matched the duration of the first smog of 2018 and 2020 season -- both lasted six days. If conditions don"t improve, it might overtake the 2019 smog that lasted eight days, the CSE said.The average intensity of the smog this year so far is 329 microgram per cubic metre per day, which is lower than that of the 2020 smog (by 7 per cent) and 2019 smog (by 3 per cent). It is more intense than the 2018 smog (about 9 per cent).Lingering on of this year"s smog for longer duration despite relatively windier local conditions might be due to the lack of pollution control measures in the city, the green think tank said.“While very high concentrations of PM2.5 have hogged attention, the levels of gases – ozone, CO or NO2 -- have remained elevated during this smog episode. Also, the ratio of SO2 to NO2 increased on Diwali night indicating increased pollution load from firecrackers.

First severe smog episode hits Delhi, may be longest in 4 years: Report

The average intensity of smog in Delhi so far is 329 micrograms per cubic meter per day. Green think-tank Center for Science and Environment (CSE) today said that the first severe smog episode has affected Delhi and National Capital Region (NCR) and is expected to last for the next two days. Although the seasonal haze in Delhi is intense, the average daily contribution of smoke from farm fires from mid-October to November 8 has been the lowest in the past four years. “Presumably, the first episode of the season has started with a combined effect of adverse weather conditions (cold and calm winds and inversion), stubble burning and firecrackers,” said Anumita Roychowdhury, executive director (research and advocacy), CSE. Compared to the first smog episode of the previous four years, the current smog corresponds to the first smog period of the 2018 and 2020 seasons – both lasting six days. The CSE said that if the situation does not improve, it may go beyond the eight-day haze of 2019. The average smog intensity so far this year is 329 micrograms per cubic meter per day, which is lower than the 2020 smog (7%) and 2019 smog (3%). It is more intense than the 2018 smog (around 9 per cent). The green think tank said this year’s haze could be prolonged despite relatively windy local conditions, due to a lack of pollution control measures in the city. “While very high concentrations of PM2.5 have attracted attention, levels of gases – ozone, CO or NO2 – remain elevated during this smog episode. Also, the ratio of SO2 to NO2 increased on Diwali night This indicates an increase in pollution load. Firecrackers.

Delhi in grip of season’s 1st smog episode, could be longest in 4 yrs: Report

New Delhi: The first severe smog episode has hit Delhi and the National Capital Region (NCR) and is expected to last for another two days, green think-tank Centre for Science and Environment (CSE) said on Wednesday.

This the second highest daily contribution percentage recorded since such estimation was started by SAFAR in 2018. The highest single day contribution percentage has been 58 per cent recorded on November 5, 2018. “The ongoing smog episode is a public health emergency. This requires urgent emergency action on key combustion sources (vehicles, industry, waste burning) and dust sources (construction and roads) to prevent further trapping of pollution when there is no wind to blow this away. We need pollution-source-wise and hotspot-wise status of action,” Roychowdhury said.

Delhi-NCR Gripped by Season’s First Smog Episode, Could be Longest in 4 Years: CSE Report

Lingering on of this year's smog for longer duration despite relatively windier local conditions might be due to the lack of pollution control measures in the city, the green think tank said. New Delhi: Raising major concerns about the overall health and well-being of residents, the first severe smog episode has hit Delhi and the National Capital Region (NCR) and is expected to last for another two days, green think-tank Centre for Science and Environment (CSE) said on Wednesday. Though the seasonal smog in Delhi is intense, the average daily contribution of smoke from farm fires from the middle of October to November 8 has been the lowest in last four years, it said.Also Read - Air Pollution Crisis : Expert Tips to Protect Yourself From Unhealthy Air | Watch Video Compared to the first smog episode of previous four years, the current one has matched the duration of the first smog of 2018 and 2020 season — both lasted six days. If conditions don’t improve, it might overtake the 2019 smog that lasted eight days, the CSE said. The average intensity of the smog this year so far is 329 microgram per cubic metre per day, which is lower than that of the 2020 smog (by 7 per cent) and 2019 smog (by 3 per cent). It is more intense than the 2018 smog (about 9 per cent).

Delhi in grip of first smog episode of season may be longest in 4 years: Report

New Delhi: Green think-tank Center for Science and Environment (CSE) on Wednesday said the first severe smog episode has affected Delhi and the National Capital Region (NCR) and is expected to last for the next two days. Although the seasonal haze in Delhi is intense, the average daily contribution of smoke from farm fires from mid-October to November 8 has been the lowest in the past four years. CSE’s executive director (research and advocacy) Anumita Roychowdhury said, “Presumably, the first episode of the season has started with a combined effect of adverse weather conditions (cold and calm winds and inversion), stubble burning and firecrackers.” Compared to the first smog episode of the previous four years, the current smog corresponds to the first smog period of the 2018 and 2020 seasons – both lasting six days. The CSE said that if the situation does not improve, it may go beyond the eight-day haze of 2019. The average smog intensity so far this year is 329 micrograms per cubic meter per day, which is lower than the 2020 smog (7%) and 2019 smog (3%). It is more intense than the 2018 smog (around 9 per cent). The green think tank said this year’s haze could be prolonged despite relatively windy local conditions, due to a lack of pollution control measures in the city. “While very high concentrations of PM2.5 have attracted attention, levels of gases – ozone, CO or NO2 – remained elevated during this smog episode. Also, the ratio of SO2 to NO2 increased on Diwali night , which reflects the increasing pollution load from firecrackers. The concentration of PM2.5 on Diwali night (8 pm to 8 am) has been highest since 2017. The analysis is based on real-time data available from currently operational air quality monitoring stations in Delhi-NCR and the larger Indo-Gangetic plain. “On an average, the contribution of smoke to Delhi’s daily PM2.5 during mid-October to November 8 has been the lowest in the last four years. So far, it has been recorded at an average of 12 per cent per day, as against 17 per cent per day in 2020, 14 per cent per day in 2019 and 16 per cent per day in 2018 (as reported by SAFAR). CSE said. “If converted into absolute concentrations, the per day contribution of smoke so far this year was 26 micrograms per cubic meter as compared to 35 micrograms per cubic meter in 2020, 40 micrograms per cubic meter in 2019 and 31 micrograms per cubic meter in 2018. meter was ,” it said. However, the peak contribution of smoke to Delhi’s PM level was recorded on November 7, when it reached 48 per cent. This is the second highest daily contribution percentage recorded since such an estimate was introduced by SAFAR in 2018. The highest single day contribution percentage has been recorded at 58 percent as on November 5, 2018. “The ongoing smog episode is a public health emergency. This requires immediate emergency action on major combustion sources (vehicles, industry, waste burning) and dust sources (construction and roads) to prevent further trapping of pollution when there is no air to remove it. We need a situation of pollution-source-wise and hotspot-wise action,” Roychowdhury said.
