China – January 10th, 2013

A dense haze would hit many provinces in China, including Hebei, Shandong, Zhejiang, Hubei and Sichuan, reducing visibility to less than 1,000 meters. In some areas, a blanket of snow can be seen through the haze.

The haze is likely caused by a combination of fog, smoke and pollutants. China’s economy has skyrocketed, but at a price. Power plants, factories and heavy industries are all belching out black, dirty air, at the cost of our health and our environment.¬†Millions of people in China and Hong Kong are breathing a hazardous cocktail of chemicals every day. These chemicals are caused by coal-fired power plants, factories and vehicles, and are responsible for heart disease, stroke, respiratory illnesses, birth defects and cancer.¬†According to the World Health Organization, in China more than 650,000 people die each year from diseases related to air pollution.

China – January 6th, 2013

Thick fog and haze shrouded central and northern parts of China in early January. Hebei and Henan provinces (visible here west and southwest of the Bohai Gulf, respectively) were listed among the most polluted areas, monitoring data showed. An air quality report from the Ministry of Environmental Protection ranked Handan, Baoding and Shijiazhuang in Hebei and Zhengzhou in Henan as the top four most-polluted cities among 120 monitored nationwide.

Around the time this image was captured, the Air Pollution Index in the four cities reached 500, the maximum on the index. An API reading below 50 indicates excellent air quality, 50 to 100 indicates healthy air, and readings above 100 mean polluted air. Experts and residents in the worst-hit areas are becoming increasingly worried about the air pollution brought by frequent winter haze. Greenpeace warned that wsall particles in the air can cause heart disease, stroke, respiratory illness, birth defects and cancer.

China - October 29th, 2011

Haze or smoke over eastern China rests near the foot of the Taihang Mountains, a range running down the eastern edge of the Loess Plateau in Henan, Shanxi and Hebei provinces.

The range extends over 400 km from north to south and has an average elevation of 1,500 to 2,000 meters. The principal peak is Xiao Wutaishan (2,882 metres). Cangyan Shan in Hebei forms the eastern tip of the Taihang range.

Dust Storm in China - March 22nd, 2010

Beijing has been shrouded in orange dust as a strong sandstorm blew hundreds of miles from drought-struck northern China to the nation’s capital. Authorities have issued a level-five pollution warning and urged people to stay indoors.

Here, the dust can be seen veiling mainland China, while offshore thick sediments are released into the Bohai Sea (above) and the Yellow Sea (below).

The storm has already caused havoc in Xinjiang, Shanxi, Shaanxi and Hebei regions and is heading to South Korea (visible to the right upon opening the full image). Residents of the South Korean capital, Seoul, as well as those in central and western regions, have been advised to stay indoors.

By Saturday, the storm had spread over an area of 810,000 sq km (313,000 sq miles) with a population of 250 million, state news agency Xinhua reported. It was expected to last until Monday, the meteorological agency said in a statement on its website.

The head of Beijing’s meteorological agency said the storm came from the deserts of Inner Mongolia. Beijing has long-suffered from sandstorms – experts say the storms are, in part, caused by deforestation and the rapid expansion of urban areas in recent decades.

Some sediments are present along the west coast of the Korean Peninsula (lower right quadrant), mainly by South Korea, and along the coast of the Bohai Sea (lower left edge) and Shandong Peninsula (bottom left) in northeast China.

The sediments appear most concentrated in Liaodong Bay, one of the three bays forming the Bohai Sea. It borders Hebei province and Tianjin Municipality. Most of these sediments are flowing forth from the Daliao River, which has its estuary on the shores of the bay.
