Air Pollution and Your Health -

· PM accounts for most health effects due to air pollution in the Volatile organic compounds (VOC) vaporize at or near room temperature—hence, the designation volatile. They are called organic because they contain carbon. VOCs are given off by paints, cleaning supplies, pesticides, some furnishings, and even craft materials like glue. Gasoline and natural gas are major sources of …

Ambient (outdoor) air pollution

The Air Quality Index is based on measurement of particulate matter (PM and PM 10), Ozone (O 3), Nitrogen Dioxide (NO 2), Sulfur Dioxide (SO 2) and Carbon Monoxide (CO) emissions. Most of the stations on the map are monitoring both PM and PM 10 data, but there are few exceptions where only PM 10 is available. All measurements are based on hourly readings: For instance, an AQI reported ...

European Air Quality Index

The relative risk of exposure to PM is taken as basis for driving the index, specifically the increase in the risk of mortality per 10 µg/m 3 increase in the daily mean concentration of PM Assuming linearity across the relative risks functions for O 3 and NO 2 , we calculate the concentrations of these pollutants that pose an equivalent relative risk to a 10 µg/m 3 increase in the ...

COVID-19 lockdowns cause global air pollution declines | PNAS

· This timing was strongly evident for PM in China (decline of 16 µg⋅m −3) and India (decline of 15 µg⋅m −3), but less so for PM over European countries. This may be because PM is significantly influenced by long-distance atmospheric transport, and, therefore, the local effects of economic activity over Europe may have been diluted or even counteracted ( 17 ).
