Heavy metals including mercury, lead, cadmium, copper, nickel, chromium, and zinc in the contaminated soil have adverse health effects in human metabolism. Ingestion, contact through skin, diet through the soil-food chain, respiratory intake, and oral intake can deliver the toxic substances to human beings.
Background[ edit ] In JanuaryChina experienced massive fog and haze outbreak affecting about million people and covering seventeen Chinas smog paper, municipalities and autonomous regions, a fourth of China's territory.
Addressing Climate Change ". It stated that the fog and smog in China had increased in the past 50 years with the number of fog-free days significantly reduced, while that of the smog days were significantly increasing with the phenomenon of persisting smog days.
The fastest growing fog and smog days occurred in the Pearl and Yangtze River Delta regions, which are the most industrialized areas.
The report also indicated that the main reason of increased fog and smog days is the yearly increase in fossil fuel consumption in China. The report calls for urgent implementation of regional joint prevention and control measures to effectively solve the air pollution crisis.
The National Meteorological Center NMC issued yellow alert for smog and fog, the third most serious alert in China's four-tiered system. Embassy categorizes air quality readings over as hazardous to all humans, not just those with heart or lung ailments. Causes[ edit ] Coal burning is a primary source of fine particle air pollution.
It increased as the weather worsened during winter months and residents burned more coal to keep warm. This increased the amount of sulphate and nitrate results of coal combustingwhich led to higher PM2.
JiangsuAnhui, ShandongHenan and many eastern provinces are heavy coal-burning regions. Research shows that prevailing winds blew low-hanging air masses of factory emissions mostly SO2 towards the east coast of China. The State Environmental Protection Administration investigates tens of thousands of polluters every year, shutting down thousands of the worse offenders, but has failed to reach its target of reducing emissions by 2 percent.
With such a high concentration of air pollutants, government authorities warned residents of health symptoms, such as coughing and headaches. Citizens were advised to wear protective masks and use air purifiers. Many sanitation workers were required to wear dust masks during work early in the morning.
Schools were closed as the government ordered children to stay indoors, and reduce outdoor activities as much as possible. Construction work was halted and authorities pulled nearly one-third of government vehicles from the roads. A majority of inbound flights were cancelled and more than 50 flights were diverted at Shanghai Pudong International Airport.
PM10 also went over at times. Experts say these figures indicate high levels of dust on construction sites. Many highways in East China's Jiangxi province were closed. On 12 FebruaryChina's cabinet announced that government will implement a series of measures aimed at shifting the primary energy source from coal to natural gas and renewables.
Pricing mechanisms will be used to favor cleaner alternatives to coal. Financial incentives will be offered to encourage green energy companies. The government will place tougher controls over emissions and better support for developing clean technologies.
Small particles can be suspended in the air for long periods of time due to their low masses. While some particles such as large-size carbon may be seen as soot and smoke, most of them can only be detected with a microscope.
The Chinese Academy of Sciences indicated that smog in Beijing is a combination of both artificial factors and natural factors. While various causes such as coal burning and car emissions come from human activity, natural causes such as the humid weather and a lack of wind also contributed to the smog.
Automobile exhaust also significantly contributed to the smog problem. While these particles, along with other ozone-related chemicals, can be carried up to 30, feet above the ground, researchers in the United States predict that these pollutants may play a bigger role in the near future.Schools in Beijing are closed and outdoor construction halted as the Chinese capital's first ever pollution "red alert" comes into effect over smog levels.
This research paper should write about the causes of smog in China. The impact of Smog, for example, what disease does it bring and what damage it has to human living environment? Whether the effective control of this phenomenon of . China has stopped accepting shiploads of other countries’ plastic and paper trash, a response to public concern over pollution and a decreased need for scrap materials.

Smyth Honors English II (2) January 3, China’s Smog Epidemic Ever since the Industrial revolution, society has been advancing in many ways and the earth has been slowly getting more and more polluted.
The Eastern China smog was a severe air pollution episode that affected East China, including all or parts of the municipalities of Shanghai and Tianjin, and the provinces of Hebei, Shandong, Jiangsu, Anhui, Henan, and .
Aug 14, · The paper maps the geographic sources of China’s toxic air and concludes that much of the smog that routinely shrouds Beijing comes from emissions in a distant industrial zone, a finding that.
