China has been racing to meet the objectives set in its revised air quality standards, including promoting the use of an index for PM2.5, or fine particulate matter 2.5 microns or less in diameter. A total of 138 monitoring stations in 74 cities across the country have begun publishing data …
The average concentration of PM 2.5 in Beijing's air over the past 24 hours has exceeded the limits for "air with acceptable quality", as defined by the Ministry of Environmental Protection's air quality standards. PM 2.5 refers to particles in the air with less than 2.5 micrometers in diameter, which …
Beijing plans to finish building its PM2.5 monitor network across the city by the end of September, according to the official website of Beijing Municipal Environmental Protection Bureau. PM2.5 refers to particulate matter with a diameter of 2.5 micrometers or less. These air pollutant particles can invade even the smallest …
New Delhi:Delhi government’s environment department is set to commission IIT Kanpur to study its problem of air pollution. The government has already devised a master plan to deal with the issue and its implementation should start by next year. “The master plan is quite comprehensive but we still felt the …
Human exposure to particulate matter (PM) was determined in Urban Environment of Delhi, India. Samples were collected using eight stages impactor (Marple Cascade Impactor) at five sites during August to October 2011. Three samples were collected from each site; samples were analyzed in eight size ranges gravimetrically and chemically (for …
China's national lawmakers are debating to what extent the public should be allowed to participate in, and how much negotiating power the public should have, in environmental issues set by the government. With increasing numbers of protests against controversial government projects in China, members of the National People's Congress (NPC) …
What is the world wide trend in air pollution? On the surface North America and Europe have been gradually improving. However, that is due to often moving industry to other countries such as China or India where air pollution is a bit more of a problem. Most of the world's …
Olympic runners, cyclists, swimmers and even sailors arriving in London on Monday could be taken ill or see their performances impaired by air pollution, health experts have warned. According to Keith Prowse, respiratory consultant and medical adviser to the British Lung Foundation, a summer smog like any of the five …
Shanghai started to post readings of PM2.5 to the public from 10 monitoring stations around the city on Wednesday. PM2.5 stands for particulate matter with a diameter of 2.5 micrometers or less. These air pollutant particles can invade even the smallest airways. In the past, readings from only two control …
Authorities with Shanghai's environmental protection bureau said on Friday afternoon that it's illegal for the US consulate in Shanghai to publish assessments of air quality to the general public. Zhang Quan, director of the Shanghai Environmental Protection Bureau, said at a media conference that the consulate cannot legally reveal data …
This report presents the results of a systematic review of evidence of the health effects of black carbon (BC). Short-term epidemiological studies provide sufficient evidence of an association of daily variations in BC concentrations with short-term changes in health (all-cause and cardiovascular mortality, and cardiopulmonary hospital admissions). Cohort studies provide …
The study was carried out during the months of March-May, 2012 to see the status of air quality by monitoring and assessment of some selected air pollutants namely Respirable Particulate Matter (RSPM or PM10), Fine Particulates (PM2.5), Sulphur dioxide(SO2), Nitrogen dioxide (NO2), and Trace metals- Iron (Fe ), Nickel (Ni), …
Few cohort studies have evaluated the risk of mortality associated with long-term exposure to fine particulate matter [≤ 2.5 μm in aerodynamic diameter (PM2.5)]. This is the first national-level cohort study to investigate these risks in Canada. The authors investigated the association between long-term exposure to ambient PM2.5 and cardiovascular …
Many epidemiological studies have linked daily counts of hospital admissions to particulate matter (PM) with an aerodynamic diameter ≤ 10 μm (PM10) and ≤ 2.5 μm (PM2.5), but relatively few have investigated the relationship of hospital admissions with coarse PM (PMc; 2.5–10 μm aerodynamic diameter). The researchers conducted this study …
This report assesses the environmental, energy and financial performance of brick production in Indis and provides short-term recommendations to improve brick kiln technologies.
This paper present results of a bottom-up emissions inventory, an analysis of source-receptor relationships for PM10 and PM 2.5 for residential and industrial areas in Delhi NCR, and implications of sector based interventions on air pollution control policy. This paper present results of a bottom‐up emissions inventory, an analysis of …
Accelerating growth in the transport sector, a booming construction industry, and a growing industrial sector are responsible for worsening air pollution in Indian cities. While estimates of health impacts are effective in raising overall concern about air quality, they do not specifically answer the question of what are the sources …
Measuring the oxidative potential of airborne particulate matter (PM) may provide a more health-based exposure measure by integrating various biologically relevant properties of PM into a single predictor of biological activity. The authors aimed to assess the contrast in oxidative potential of PM collected at major urban streets and background …
The city along with winter chill in January also witnessed high concentration of fine particulate matter less than 2.5 microns which crossed permissible levels, say scientists from the Indian Institute of Tropical Meteorology (IITM). They said the quality of air is very poor. Levels of PM 2.5 have touched 135 …
There are currently around 90 cities that India's Central Pollution Control Board (CPCB) identified as critically polluted. Particulate matter (PM), especially fine particulate matter (PM2.5), dominates the concern. Other air pollutants such as NO2, ozone (O3), and air toxics are also problematic. The health problems caused by these pollutants are …
