A study of soil in China shows that about one-fifth of the country's land has been contaminated, and that about 1 million square kilometers of farmland needs about $ 1 trillion to repair.
The latest 8-year survey showed that 19.4 percent of China's agricultural land was polluted as "a major threat to China's food security," said the official Xinhua news agency, adding that the cost of repairing the contaminated land would reach 6 trillion yuan At least, "according to the agency.
According to the April 17 report, 19.4 percent of China's total land area was polluted, compared to 10 percent for forest land and 10.4 percent for soils.
China began to explore the conditions of its soil since 2005, and completed the mission, the first of its kind in the country by the end of 2013
The survey was conducted on 6.3 million square kilometers of mainland land except Hong Kong, Macao and Taiwan. This means that over one million square kilometers of Chinese soil has been contaminated.
The results of the survey showed that the soil of the southern regions of China suffer from greater pollution compared to the northern regions, and the extent of pollution caused by cadmium, one of the types of heavy metals, in a comprehensive manner in the country.
It is noted that the main cereal producing areas have also been exposed to soil contamination, which is of great concern at the national level, "where the proportion of heavy metals in the grain grown in these areas exceeded the reasonable level." The agency quoted the official report as saying.
"Soil pollution will negatively affect the production and quality of agricultural products," experts said, with serious damage to human health.
In order to deal with this serious situation, China is busy preparing a special program to address soil pollution, as well as speeding up the enactment of a Soil Protection Act.
