Plants spell out air pollution in Varanasi researchers at Benaras Hindu University (bhu) have used plants to study the impact of air pollution at the genetic level, the first-time ever, in Varanasi. They placed a locally available plant, Tradescantia pallida, at four locations, of which three were highly polluted.
victoria hospital in Bangalore is the most polluted of all areas recently studied in several cities of Karnataka. The 2007-08 report of Karnataka State Pollution Control Board (kspcb) described air pollution in the hospital area from
The present study gives an idea of changes taking place in pollen characteristics of Delonix regia and Peltophorum inerme under the influence of air pollution. Pollen germination, viability, size and pollen tube length were the parameters studied. The reduction in pollen viability and pollen tube length was more significant in …
The simultaneous determination of heavy metals associated with airborne particulate matter in the atmosphere of the city of Isfahan (Iran) was performed by inductively coupled plasma atomic emission spectrometry (ICP-AES) after pre-concentration with sodium diethyldithiocarbamate. The pre concentration procedure developed found instrumental to determine the trace heavy metals associated with …
Between 2001 and 2003, public transport vehicles in New Delhi were required to switch their fuel to natural gas in an attempt to reduce their air pollution impacts. This study examines the climatic impacts of New Delhi’s fuel switching policy, and outlines implications for such efforts in rapidly industrializing countries. …
The sulphur content of diesel in India is 350 particles per million, twenty times that of the United States. Diesel exhaust is far more hazardous than petrol exhaust. Yet, diesel cars in Indian cities are rising with the association of automobile manufacturers pushing hard for it.
MPCB"s new consent conditions • Dow to issue an undertaking that it would not use any chemicals banned by the Indian government • Install three ambient air quality monitoring stations • On monthly basis monitor ground water quality within the vicinity of the five-kilometre area of its proposed plant • …
Beijing will close factories and force 19 heavy polluters to reduce emissions by 30 per cent for two months around the Olympics and Paralympics to improve air quality for athletes, a Beijing official said yesterday. The measures, from July 20 to September 20, are an attempt to fulfill the city's …

The global motor vehicle population has grown very rapidly in the past half century and is expected to continue to grow rapidly for the next several decades, especially in developing countries. As a result, vehicles are a major source of urban air pollution in many cities and are the fastest-growing …
Concerned over the rise in pollution levels in the city along with soil and water contamination, the Delhi government has awarded a project to the Delhi University for mapping the soil, water and air pollutants district wise. The project, spanning 18 months, will help the government's action plan to control …
Air quality crisis in cities is attributable mainly to vehicular emissions. Transportation systems are expanding everywhere. This paper examines the pollutant emissions from automobiles and identifies that the capacity of routine monitoring networks and impact assessment in India is usually limited to criteria pollutants.
Hydroxyl radicals are often called the "detergent" of the atmosphere because they control the atmosphere's capacity to cleanse itself of pollutants. In this article the researchers show that the reaction of electronically excited nitrogen dioxide with water can be an important source of tropospheric hydroxyl radicals.
More than a hundred people live in cities that fail to meet international standards for air quality. Efforts to improve conditions in these urban areas have usually focussed on reducing emissions of reactive hydrocarbons, nitrogen oxide free radicals and primary and secondary sources of particulate matter.
A case study is done in Salem City, India for ambient air quality for major air pollutants for a period of one year from Oct 2003 to Sep 2004 at the six selected stations. (2007)
Chennai Metropolitan Area extends over 1180 sq. km and has a population of more than 8.5 million. Rapid increase in urbanization with vehicle congestion has increased menacingly on the roads of Chennai. As a result of this, gaseous pollutants and respirable and suspended particulate matter pollutants are continuously increasing in …
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). One of the key factors in …
Foggy conditions during winters in Delhi have increased drastically over the past decade.
