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 …
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 …
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 …
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 …
HONG KONG: Environmentalists on Wednesday expressed disappointment at new clean-air targets for Hong Kong, as research showed pollution-related illnesses killed more than 3,000 residents a year. In the face of mounting public criticism and allegations that it is soft on polluting industry, the government on Tuesday announced its first revision …
Tropospheric ozone and black carbon (BC) contribute to both degraded air quality and global warming. We considered ~400 emission control measures to reduce these pollutants by using current technology and experience. We identified 14 measures targeting methane and BC emissions that reduce projected global mean warming ~0.5°C by 2050. This …
This study under the SIM-air program was initiated with support from the Shakti Sustainable Energy Foundation (New Delhi, India) to better understand the sources of air pollution in the Pune city and to support an integrated dialogue between local pollution management and climate policy in a co-benefits framework. The main …
Ambient air pollution is associated with numerous adverse health impacts. Previous assessments of global attributable disease burden have been limited to urban areas or by coarse spatial resolution of concentration estimates. Recent developments in remote sensing, global chemical-transport models, and improvements in coverage of surface measurements facilitate virtually complete spatially …
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 …
As part of the System of Air quality Forecasting and Research (SAFAR) project developed for air quality forecasting during the Commonwealth Games (CWG) – 2010, a high resolution Emission Inventory (EI) of PM10 and PM2.5 has been developed for the metropolitan city Delhi for the year 2010. The comprehensive inventory …
This paper reports the atmospheric concentrations of PM2.5 and PM1 mass, water soluble inorganic components and their seasonal variations measured between the period of July 2009 and June 2010 in Durg city (20°23' to 22°02'N and 80°46' to 81°58'E), India.
The database contains results of urban outdoor air pollution monitoring from almost 1100 cities in 91 countries. Air quality is represented by annual mean concentration of fine particulate matter (PM10 and PM2.5, i.e. particles smaller than 10 or 2.5 microns). The database covers the period from 2003 to 2010, with …
An Autoricshaw ride in Delhi comes at a great cost, and not just for your pocket. A recent study conducted by Joshua Apte, a PhD candidate from the University of Berkeley, has found that a single trip in an autorickshaw in Delhi could expose you to levels of air pollution …
New Delhi: Ten years after the city’s public transport switched to CNG, air pollution has again become a major threat to public health in Delhi, say environmentalists. With 69 lakh vehicles plying on city roads, a growth of about 60 lakh in 20 years, experts say oxides of nitrogen (NOx) …
Centre for Science and Environment joined hands with Indian Council for Medical Research and Indian Medical Association to organize a dialogue with the noted doctors – (respiratory physicians, cardiologists, pediatricians, oncologists), the air quality regulators, and health experts to track the newer concerns over health risks of polluted air. Source: …
Concentrations of air pollutants from vehicles are elevated along roadways, indicating that human exposure in transportation microenvironments may not be adequately characterized by centrally located monitors. We report results from w180 h of real-time measurements of fine particle and black carbon mass concentration (PM2.5, BC) and ultrafine particle number concentration …
The main objectives of the study were to measure the indoor air quality in hospital with special emphasis on particulate matter (PM10, PM2.5 and PM1.0).
