Controlling smog and soot is the classic win-win situation, so it's great that the world is finally waking up to the idea, says Drew Shindell.

This work presents an estimate of the air pollution from municipal solid waste transport haulage sector for the city of Kolkata. About 3000 MT/day of solid waste are generated in the city presuming generation rate of 450-500 gm/capita resident/day. On an average, 205 private carriers transport 60% of daily generated garbage (responsible for 44% of total air pollutants from municipal solid waste transport), while around 109 nos. of departmental vehicles transport the remaining 40% of waste (responsible for 56% of total pollution emission from waste transport).

The seasonal variability of biomass open burning activities in the Greater Mekong sub-region (GMS) with focus on carbon monoxide (CO) and total particulate matter or aerosol (TPM) emissions was investigated in order to document the characteristics of this significant source of air pollutants in the region.

Air pollution has long been a problem in the industrial nations of the West. It has now become an increasing source of environmental degradation in the developing nations of east Asia. China in particular, because of its rapid push to industrialize, is experiencing dramatic levels of aerosol pollution over a large portion of the country. India’s air pollution, because it is also rich in black carbon, has reached the point where scientists fear it may have already altered the seasonal climate cycle of the monsoons.

Residents living near a coal-fired thermal power plant project in southernmost Burma are growing more concerned over health issues associated with the power plant, which could begin operations in April, local media report said.
The power plant, north of Kawthaung about 800 kilometres from Rangoon, is located 50 feet from residential areas and its chimney is about 40-foot high, residents said.
A reservoir that provides drinking water to Kawthaung is about 450 yards from the plant and local people fear the water will be polluted by the plant's emissions.

The air was monitored for two consecutive periods, in the dry and the rainy seasons (2009-2010) at 40 petroleum-filling stations in the Indian capital, Delhi, to assess variations in carbon monoxide, nitrogen dioxide, PM10, PM2.5, benzene, toluene and xylene content. PM10 and PM2.5 concentrations exceeded the national ambient air quality standards at all the monitoring locations with maximum values of 1105 and 625 μg m−3, respectively, in the dry season.

The Department of Environment (DoE) yesterday fined an illegal steel re-rolling mill Tk 15 lakh for polluting air with toxic smoke at Rupganj in Narayanganj.

DoE Director M Munir Chowdhury fined AK Majumder Steel Mills Ltd and ordered its closure as per the environment preservation law, says a press release.

The factory, which had been operating without environmental clearance for the last one and a half years, emitted toxic smoke containing metal elements including sulphur dioxide, carbon dioxide and carbon monoxide.

Traffic congestion in the capital and smoke from brick kilns are the main reasons for air pollution in Dhaka city, according to the World Bank and the Bangladesh government.

The Ministry of Environment and Forests says that vehicles in Dhaka move 14kmph on an average, which is very slow and causes them to burn more fuel and contribute to air pollution. They say the average speed could come down to 4kmph by 2025 if things do not improve.

Public awareness campaigns about pollution seems to have paid off as the City recorded a decrease in pollution levels during Deepavali celebrations compared to last year. However, the number of firecracker-related accidents has increased.

Karnataka State Pollution Control Board chairperson A S Sadashivaiah on Friday revealed the noise and air pollution readings recorded during the three days of Deepavali celebrations.

CPCB figures indicate lesser pollution, govt claims it is due to anti-cracker campaign
Increased awareness and favourable meteorological factors have led to a decrease in overall air pollution this Diwali compared to last year’s figures, the Central Pollution Control Board (CPCB) has said.
