In September 2017, China’s Ministry of Environmental Protection issued the first national standard for portable emission measurement system (PEMS) testing of heavy-duty vehicles (HDVs).

Poor air quality is one of the leading five health risks worldwide, along with high blood pressure, tobacco smoking, diabetes and being overweight. In 2015, it contributed to nearly 8% of all deaths worldwide. Long-term exposure to polluted air has been linked to respiratory infections, chronic obstructive pulmonary disease, stroke, heart attack and lung cancer. It is justifiably called ‘passive outdoor smoking’.

While parts of North India battle the life-threatening smog, there is some good news and some bad news.

MANGALURU: ASSOCHAM has advocated giving adequate time to the industrial consumers to migrate from the furnace oil and pet coke to gas-base to save the livelihood of over 25 lakh workers in the nat

In response to global warming, the Brewer–Dobson circulation in the stratosphere is expected to accelerate and the mean transport time of air along this circulation to decrease. This would imply a negative stratospheric age of air trend, i.e. an air parcel would need less time to travel from the tropopause to any point in the stratosphere. Age of air as inferred from tracer observations, however, shows zero to positive trends in the northern mid-latitude stratosphere and zonally asymmetric patterns.

Noting that air pollution has reached crisis level in Northern India, government think-tank Niti Aayog has recommended a slew of measures like imposing higher taxes on petrol in and around the more

Green activist Sunita Narain on Thursday said the Environment Pollution Control Authority, of which she is a member, is determined to get a ban on petcoke import as the country should not become a

Nowadays, most of the research on air pollution and its adverse effects on public health in China has focused on megacities and heavily-polluted regions. Fewer studies have focused on cities that are slightly polluted. Shenzhen used to have a favorable air environment, but its air quality has deteriorated gradually as a result of development in recent years. So far, no systematic investigations have been conducted on the adverse effects of air pollution on public health in Shenzhen.

Scientists have developed a catalyst that can curb emissions of nitrogen oxides from diesel-powered vehicles, an advance that may help reduce air pollution and smog.
