Reply by the Central Pollution Control Board (CPCB) in compliance to the National Green Tribunal (NGT) order dated January 21, 2024 in the matter of ‘News item titled “Feeling anxious? Toxic air could be to blame” appearing in Times of India dated 10.10.2023’. NGT had directed CPCB to file a …
Mitsui & Co, Japan has admitted that it obtained an approval to sell its Diesel Particulate Filter ( dpf ) by using falsified tests results. dpf are after-treatment exhaust devices, that provide more than 90 per cent control of diesel particulate matter (pm). False data was included in the certification …
Frenzied developments on the energy front in India are indicative of the domestic automobile industry chasing us President George W Bush's hydrogen economy dream, which is thought to be more of a chimera. The industry, in collaboration with India's Union ministry of non-conventional energy sources (mnes), is planning to put …
When Faridabad resident Rajendra Dhankar's eight-month-old Santro began to belch white smoke like a run-down truck, he rushed to the vehicle's manufacturer, Hyundai. What had caused the engine to so wheeze was heavily adulterated fuel. The company replaced the piston and the ring. Dhankar's car was as good as new …
A wide variety of low priced fuels and solvents in the market are an immediate enticement to greed. High taxes on petrol make it vulnerable to adulteration with cheap solvents and naphtha. Diesel is easily mixed with subsidised kerosene and cheaper LDO. Says Rita Pandey, Fellow, National Institute of Public …
Towards the end of 2001, as part of an ongoing public interest litigation on air pollution in Delhi, the apex court took notice of the ugly business of adulteration. It has repeatedly pointed out the merit of the CNG programme in culling this menace. But the Union of India, in …
The Western world has come a long way in its drive to reduce air pollution from vehicles. Just over a decade back, the focus was on total suspended particulate matter (which includes natural dust too) and the black smoke vehicles emitted. Epidemiological evidence made governments shift the focus to respirable …
Research on nanoparticle emissions from vehicles is still in the academic domain. This is largely because the uncertainty over formation of nanoparticles and their measurement methods. As a spillover, regulatory mechanisms are not yet able to take into account this new science. They still use mass of emitted particles
Improved engine technology and fuel quality has thus created a new debate. “Ironically, particle control regulations may have made the situation worse,” points out Wexler, referring to increased nanoparticle emissions. Andreas Mayer, an engineering consultant based in Switzerland, does not quite agree. “Engine development does reduce the number of the …
The alternative energy industry is stepping on the gas. Top automakers have joined hands to deve-lop fuel cell technology for cars, enabling them to cover similar distances as gasoline-run cars. The Japan-based effort has brought together Toyota Motor, Nissan Motor, Daimler-Chry-sler ag, Ford Motor and several other automobile and component …
