Reuters reported that China is awash in “out of control” acid rain. Acid rain fell on more than 250 cities nationwide and caused direct annual economic losses of 110 billion yuan. The rapidly growing number of cars and increasing consumption of cheap, abundant coal are the main causes of the acid rain in China, as the country is struggling to meet the energy demand.
BEIJING (Reuters) – China’s explosive economic growth is outpacing environmental protection efforts, leaving the country awash in “out of control” acid rain, the China Daily said Tuesday.
Acid rain fell on more than 250 cities nationwide and caused direct annual economic losses of 110 billion yuan ($13.3 billion), equal to nearly three percent of the country’s gross domestic product, the state-run newspaper said.
“The regional acid rain pollution is still out of control and even worse in some southern cities,” Wang Jian, an official with the State Environmental Protection Administration, was quoted as saying.
Two major causes were the rapidly growing number of cars and increasing consumption of cheap, abundant coal as the country struggles to cope with energy shortages and meet power demand.
China is the world’s largest source of soot and sulphur dioxide (SO2) emissions from coal, which fires three-quarters of the country’s power plants.
More than 21 tons of SO2 were discharged in China in 2003, up 12 percent from the year earlier, the paper said.
“It is estimated that the country will consume more than 1.8 billion tons of coal in 2005, emitting an additional six million tons of SO2,” Wang said. The paper said the government was planning steps to rein in the problem, including setting quotas for SO2 emissions from thermal power plants and urging them to install desulphurization facilities, through Wang admitted earlier efforts had led to no obvious improvements.
China has already banned the use of coal in some areas most severely affected by SO2 emissions, but sulphur is not the only enemy in the fight against acid rain.
“The amazing growth of nitrates, thanks to a swift rise of automobile and coal consumption plus overuse of fertilizers, is playing an increasing role in the country’s acid rain pollution,” Tang Dagang, director of the Chinese Research Academy of Environmental Sciences, was quoted as saying.
A government official told the paper that China had yet to set special regulations to control nitric acid.
