Air pollution has become a major problem in China, and poses a threat to Chinese public health,including Acid RainOzone Depletionand Smog.A recent study by a Chinese research institute found that 400,000 premature deaths are caused every year in China by diseases linked to air pollution. And Chinas Ministry of Science and Technology reports that 50,000 newborn babies are killed by air pollution a year.Acid Rain is the result of the emissions of sulfate and nitrates into the atmosphere from the burning coal to produce electricity and deposited to the earths surfaces as an acid.Scientists have discovered a hole over the Antarctic and some mid-altitude regions over Chile in South America. The Mapuche Nation lives under one of these holes in the ozone and they have seen an increased number of skin cancer and blindness among their people.Thick smog has shrouded central and northern parts of China. Hebei and Henan provinces are among the most polluted areas. But the most polluted major city has been the capital, Beijing. Visibility is down to 100 meters in Beijing, and drivers have turned on their lights during the day time.Beijing is on its sixth day of an orange smog alert - the second-highest on the scale - with the air tasting gritty and visibility down to a few hundred metres. The choking smog has seen sales of anti-pollution products boom and online face-mask stores were struggling to meet demand. 1.what is smog?Smog is a type of air pollutant. It is a type of air pollution derived from vehicular emission from internal combustion engines and industrial fumes that react in the atmosphere with sunlight to form secondary pollutants that also combine with the primary emissions to form photochemical smog.Coal combustion generates particulate matter also known as PM. Currently Beijing is suffering from PM2.5, which is a particulate matter with diameter of 2.5 micrometers or less.2.causeCoal fires, used to heat individual buildings or in a power-producing plant, can emit s
