Over the past decade there has been mounting evidence that ambient air pollution during pregnancy influences fetal growth. This study was designed to examine possible associations between fetal ultrasonic measurements collected from 15,623 scans (13

Major sources of air pollution in urban areas include combustion processes (e.g., including the burning of fossil fuels for steam and power generation, heating and household cooking, waste burning, and gasoline and diesel-fueled engine combustion) and various non-combustion industrial processes (e.g., solvent extraction processes).

Air quality in Europe has declined in recent years, according to a report from the European Topic Centre on Air and Climate Change (ETC/ACC), which also cautions that the short time period involved makes it difficult to draw reliable conclusions. March 2008

Residue burning practice is followed in major Indian states of Uttar Pradesh and Punjab. Agricultural residue burning in the fields and used otherwise for rural domestic needs is responsible for a large number of toxic emissions, which are a health hazard.

Crop residue burning results in the emission of many a toxic pollutants. These emissions can travel long distances affecting thereby the entire region. Due to these emissions the air quality of the region worsens, which results in nose and throat itching and burning, and irritation of the airway tract.

To alleviate traffic congestion in Central London, the Mayor introduced the Congestion Charging Scheme (CCS) in February 2003.

The major objectives of this study are: assessment of air pollution concentrations at different locations with varying number of anthropogenic sources of pollution; to study the temporal and diurnal variation in pollutants concentration along with traffic activities; to assess the status of air pollution to adjudge the effectiveness of air pollution control strategies and long term management of air pollution; and to formulate further preventive and control measures for abatement of air pollution.

Building an effective air quality management system (AQMS) requires a process of continual improvement, and the source apportionment techniques described in this report can contribute in a cost effective manner to improving existing systems or

Air pollution continued to challenge the nation in 2004, 2005, and 2006. Some cities

The present study deals with the assessment of ambient air quality with respect to respirable suspended particulate matter (RSPM or PM10 <10
m) and trace metals (Fe, Zn, Cu, Cr, Ni, Cd, Mn and Pb) concentrations in RSPM at five locations of Renukoot, an industrial area of Eastern Uttar Pradesh.
