PM2.5 pollution

The British government has published the data of a research that it has conducted by examining 50,000 homes, of which it has detected the emissions of pollutants, and the results speak very clearly: wood stoves commonly used in the home contribute much more to pollution than do not do road traffic.

The percentages leave no room for doubt: 17% of the polluting particles in the air come from household heating, a figure that significantly exceeds the 13% represented by pollution from from cars, although a clear improvement compared to 38% of previous research, while one of the major contributions to air pollution comes from industry, which accounts for 27%.

The question of wood stoves is really delicate: in recent years the diffusion of this type of stove has been really widespread, even if in 95% of cases the stoves are found in homes that also have other sources of heating. All this also translates into direct exposure to PM2.5 by those who use these stoves routinely in their homes, with possible damage to health, even very serious: this particulate has in fact the ability to deposit in human organs, even reaching to cause tumors.

For this reason and for many others, there are various groups of ecologists who have long been asking for a ban on wood stoves, or at least for the interruption of the sale of new models - which despite being improved from the point of view of emissions they are still enormously more polluting than a latest generation truck: the quantity of polluting particles emitted by a modern stove exceeds by 750 times those emitted by a transport truck.

Deaths linked to PM2.5 pollution in India increased by 2.5 times in 2 decades: Report

Deaths linked to PM2.5 pollution in India increased by 2.5 times in 2 decades: ReportDeaths attributable to PM2.5 pollution in India have increased by 2.5 times over the last two decades, according to a new report by the Centre for Science and Environment.

The report released by Union Environment Minister Bhupender Yadav on Tuesday said India accounted for one out of every four deaths due to air pollution in 2019.

Data collated by green think-tank Centre for Science and Environment (CSE), and represented in its 'State of India's Environment Report', showed that 6.67 million people died due to air pollution in the world.

Of these, 1.67 million deaths occurred in India. China saw 1.85 million deaths due to air pollution.

The report said 4,76,000 infants died globally in their first month of life from health effects associated with air pollution exposure in 2019. Of these, 1,16,000 deaths occurred in India.

Poor air quality was the fourth leading risk factor for early death worldwide in 2019, surpassed only by high blood pressure, tobacco use and poor diet.

'Over the last two decades, deaths attributable to ambient PM2.5 in India has increased by 2.5 times -- from 2,79,500 in 1990 to 9,79,900 in 2019,' the report read.

PM2.5 refers to fine particles which penetrate deep into the body and fuel inflammation in the lungs and respiratory tract, leading to the risk of cardiovascular and respiratory problems, including a weak immune system.

Deaths attributable to ozone in India has increased by 2.9 times -- from 43,200 in 1990 to 1,68,000 in 2019, it said.

However, deaths due to household air pollution in the country decreased by over 40 per cent -- from 10,41,000 in 1990 to 6,06,900 in 2019, the data showed.
