Major domestic pollutants contain 17% of carbon dioxide, 13% of carbon monoxide, 6% of nitrogen monoxide, polycyclic aromatic hydrocarbons, and fine and ultrafine particles. [16] In the United Kingdom domestic combustion is the largest single source of PM2.5 annually.
Air pollution is among the biggest health problems of modern industrial society and is responsible for more than 10 percent of all deaths worldwide (nearly 4.5 million premature deaths in 2019), according to The Lancet. Air pollution can affect nearly every organ and system of the body, negatively affecting nature and humans alike.
The main goal of the plan is to reduce coal consumption by closing polluting mills, factories, and smelters and switching to other eco-friendly energy sources. [73] These policies have been taking effect, and in 2015, the average PM2.5 in 74 key cities under the monitoring system was 55 μg/m 3, showing a 23.6% decrease as of 2013. [75]
Major sources are defined as sources that emit 10 or more tons per year of any of the listed toxic air pollutants, or 25 or more tons per year of a mixture of air toxics. These sources may release air toxics from fugitive emissions (equipment leaks), when materials are transferred from one location to another, or during discharge through ...
Approximately ten government departments and ministries under the State Council monitor food safety in China. [15] These include the Ministry of Health, the State Food and Drug Administration, and the Ministry of Agriculture, the State Administration for Industry and Commerce, the General Administration of Quality Supervision, Inspection, and Quarantine, the Ministry of Commerce, the Ministry ...
On 8 March 2012, the department started reporting data on fine suspended particulates in the air on an hourly basis, that are a leading component of smog. It began regular monitoring of PM2.5 levels, which measure 2.5 micrometres in diameter or less, at three stations since 2005, but the data were never publicised. [5]

The country implemented a clean air policy to reduce the road transport sector, which is responsible for 85% of particulate matter of less than 2.5 microns (PM2.5) total emissions and 72% of particulate matter of less than 10 microns (PM10) [38] Most successful policies were: Improving fuel quality by reducing the sulfur content in diesel
