The pollution watchdog’s study on emissions provides a database that could be used to give a policy message. It declared CNG to …
CSE comments on CPCB's recently released Study of Exhaust Gases from Different Fuel-based Vehicles for Carbonyls and Methane Emissions. Urges CPCB to recall and urgently review this study to make it more scientifically tenable. CPCB has made a valuable effort to generate emissions data on unregulated toxic emissions as well …
GAUGING a river’s health need not be complex. Taxonomists can make the job very simple. These biologists, who have specialised in the classification of organisms, can determine a river’s health with the unaided eye by simply studying the organisms present.
