Air pollution leads people to be exposed to fine particles in polluted air that penetrate deep into the lungs and cardiovascular system, causing diseases including stroke, heart disease, lung cancer, chronic obstructive pulmonary diseases and respiratory infections. Industry, transportation, coal power plants and household solid fuel usage are ...
Air quality improved by 35% in the highly polluted northern Chinese cities between 2013 and 2017. This represented significant progress, but China still has a considerable problem with its air quality today. The annual average concentration of fine particulate matter (PM2.5) across China was 57 micrograms per metre cubed in 2017, nearly six ...
Air pollution in China has gone beyond pre-crisis levels for a 30-day period from mid-April. Polluting industries are seeing a spike in activity. Recent studies suggest a correlation between air pollution levels and deaths from coronavirus. Air pollution in China has risen above levels seen before the coronavirus pandemic for the first time.
Rob Smith. Scientists at China’s Institute of Earth Environment have constructed what they say is the world’s largest air purifier in the northern city of Xian. The experimental smog-sucking tower stands at over 100 metres tall and is designed to improve air quality in the city, where standards regularly fall short of expectations set by ...
Exposure to higher levels of pollution caused by burning free coal for winter fuel. So discovered Professor Guojun He and his colleagues when they looked at the health impact of China’s Huai River Policy, which, since the 1950s, has been giving free or subsidized coal to residents living north of the river.
Air pollution is contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere. Household combustion devices, motor vehicles, industrial facilities and forest fires are common sources of air pollution. Pollutants of major public health concern include ...
Ambient (outdoor) air pollution is estimated to have caused 4.2 million premature deaths worldwide in 2019. Some 89% of those premature deaths occurred in low- and middle-income countries, and the greatest number in the WHO South-East Asia and Western Pacific Regions. Policies and investments supporting cleaner transport, energy efficient homes ...
Household air pollution was responsible for an estimated 3.2 million deaths per year in 2020, including over 237 000 deaths of children under the age of 5. The combined effects of ambient air pollution and household air pollution are associated with 6.7 million premature deaths annually. Household air pollution exposure leads to noncommunicable ...
WHO's air quality database compiles data on ground measurements of annual mean concentrations of particulate matter of a diameter equal to or smaller than 10 μm (PM10) or equal to or smaller than 2.5 μm (PM2.5) which aim at representing an average for the city or town as a whole, rather than for individual stations. The database currently hosts 4300 human settlements in 108 countries and is ...
A new report released by the World Health Organization (WHO) in Geneva shows that air pollution levels remain dangerously high in many parts of the world, including China. New data contained in the report shows that 9 out of 10 people worldwide breathe air containing high levels of pollutants. Updated estimations reveal an alarming global death toll of 7 million people in 2016 caused by both ...
