Diwali is likely to push up toxicity in Kolkata's air to an unprecedented high early next month.

The most polluted city among the metros being crowned the country’s lung cancer capital is no coincidence, but Calcutta failed — or rather refused — to see it coming.

Honeybees utilise floral odours when foraging for flowers; we investigated whether diesel exhaust pollution could interrupt these floral odour stimuli. A synthetic blend of eight floral chemicals, identified from oilseed rape, was exposed to diesel exhaust pollution. Within one minute of exposure the abundances of four of the chemicals were significantly lowered, with two components rendered undetectable.

"Climate Change 2013: The Physical Science Basis" is the contribution of Working Group I to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. This comprehensive assessment of

Bus ridership in Delhi has dropped from 60% in 2000 to 41% now. Every year, Delhi needs an area the size of 310 football fields for parking its vehicles. And Delhi has one of the highest particulate matter (PM10) levels in South Asia.

These are some of the findings of a recent Centre for Science and Environment (CSE) assessment of air pollution and policies of different cities in dealing with it. That gives you a comprehensive picture of the growing vehicular population and the resultant pollution.

Conclave of change makers for clean air and sustainable mobility - a presentation by Dr. B. Nagappa at STEPPING TOGETHER: A Conclave of Changemakers for Clean Air and Sustainable Mobility held in New Delhi from September 26-27, 2013.

Govt Fails To Save Riverine Ecosystem; Also Unable To Improve Air Quality, Contain Private Vehicle Surge

If the Congress government’s performance were measured on the yardstick of urban ecology, it would fail miserably at least on one count—the Yamuna.
Despite repeated promises of cleaning up, the river’s condition has been deteriorating by the day. However,the issue is not entirely of pollution—the flow of water in the Delhi stretch of the river is not adequate.

South Asia is extremely vulnerable, it needs to act urgently to negotiate the climate deal said Sunita Narain, Director General, CSE in this presentation at the CSE Annual South Asian Media Briefing Workshop on Climate Change, 2013 being held in New Delhi from September 18-19, 2013.

Environmental determinants of appendicitis are poorly understood. Past work suggests that air pollution may increase the risk of appendicitis. The researchers investigated whether ambient ground-level ozone (O3) concentrations were associated with appendicitis and whether these associations varied between perforated and nonperforated
appendicitis.

Agriculture is one of the largest contributors of the anthropogenic greenhouse gases (GHGs) responsible for global warming. Measurements of gas fluxes from dung pats suggest that dung is a source of GHGs, but whether these emissions are modified by arthropods has not been studied. A closed chamber system was used to measure the fluxes of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) from dung pats with and without dung beetles on a grass sward. The presence of dung beetles significantly affected the fluxes of GHGs from dung pats.
