Rising NOx levels and volatile gases in the air, primarily from vehicles, form the recipe for ozone finds this analysis by Centre for Science and Environment (CSE). Read this CSE analysis and find more in this package. Summer pollution curve takes an ugly turn as ground-level ozone, a highly reactive …
This special package consists of selected documents, reports and studies on air quality and urban mobility in Delhi. See also Delhi http://www.environmentportal.in/category/4546/thesaurus/delhi/ Air Pollution http://www.environmentportal.in/category/36/thesaurus/air-pollution/
HERBICIDES atrazine and metolachlor, commonly used to remove weeds and pests from crop fields were until now labelled nonvolatile. It was thought that most environmental risk from these pesticides comes from surface runoff—water from rain, snowmelt and other sources that flows over the land surface. But the US Department of …
Global leaders are preparing to meet in New York on September 19 and 20 to chart the way forward to tackle noncommunicable diseases, the number one killer in the world. On the stealth, the pharma and food industries and some rich countries are also at work to weaken the initiative. …
EXPOSURE to organic pollutants can disrupt the formation of nervous system in a foetus. This in turn may lead to neural tube defects. The disease affects over 320,000 infants worldwide every year. Earlier studies have linked organic pollutants like polycyclic aromatic hydrocarbons (PAHs), from indoor coal stoves, smoking and vehicle …
A recent paper of the Union Ministry of Environment and Forests (MoEF), Towards an Emission Trading Scheme for Air Pollutants in India, explores the possibility of introducing a permit and trading system for air pollutants from industrial sources. The scheme operates along the lines of the cap-and-trade mechanism for greenhouse …
MONITORING air pollution just got simpler. A handy and low-cost instrument has been developed for researchers to measure and analyse soot level in the air. Soot, or black carbon, is the second biggest contributor to global warming after carbon dioxide. It is released in the air by incomplete combustion of …
HOLDING a thermal power station in Chandrapur city in Maharashtra responsible for polluting a river, the state pollution control board has ordered forfeiture of its bank guarantee of Rs 5 lakh. Toxins released by the station killed thousands of fish in the Irai river, on whose bank it is located. …
VEHICLES and fuels must be seen as a system and not in isolation. Even a clean fuel like CNG may emit high air pollutants if the vehicle engine technology is inefficient to burn the fuel. This is the message from the first detailed testing of CNG three-wheelers in Delhi by …

A recent study by the Central Pollution Control Board has exonerated vehicles of being the worst polluters in Delhi and Mumbai. Instead, it has pinned down liquefied petroleum gas (LPG) as the biggest source of fine pollutants. Experts have contested the study, saying the findings are unsubstantiated and scientifically untenable. …
With citizens and government bodies looking to promote bicycles, a city-based engineer has claimed to have invented a solar-motor pedi-cab, (a tricycle of sorts) that could potentially replace the traditional auto rickshaw. Chunabhatti-based PK Pillai has now sent the designs to IIT-Bombay for comments are looking for funding to promote …
This report contains studies in Chennai and Delhi led by Dr. Kalpana Balakrishnan and Dr. Uma Rajarathnam, respectively. These time-series studies of air pollution and mortality in India were funded under HEI's PAPA Program to provide information to inform regulatory and other decisions that would be relevant to local populations, …
THE Asian Development Bank (ADB) has withdrawn from the Rs 200-crore wasteto- energy project at Okhla in south Delhi. The bank had promised about Rs 10 crore to the plant under the Asia Pacific Carbon Fund. ADB has not specified any reason for withdrawing from the project. Residents of Sukhdev …
This is a critical analysis by CSE of the new six-city study on air pollution sources released by Central Pollution Control Board. Says that auto industry is misusing the study to derail tighter emissions standards and encourage polluting diesel cars. Centre for Science and Environment (CSE) has pressed the alarm …
Sometime in June 2009, the West Bengal chief minister’s office forwarded a complaint to the state pollution control board (SPCB) about three sponge iron factories in West Medinipur district. A team was dispatched to Jhargram subdivision. It found a thick layer of grey dust coating trees and pathways, and noted …
