Soil pollution has become a worldwide problem. The soil pollution problem in China is serious, and according to preliminary statistics, at least 1300-1600 ten thousand hectares of farmland in China are polluted by some compounds such as pesticides. The grain yield is reduced by 1000 ten thousand tons per year due to soil pollution, and various agricultural economic losses caused by soil pollution amount to about 200 hundred million yuan. Residues of some Persistent Organic Pollutants (POPs) are eventually also transmitted to humans through the food chain. The internationally specified 12 POPs include the acronyms, dieldrin, isodieldrin, driers (DDT), chlordane, hexachlorobenzene, benomyl, toxafen, heptachloride, polychlorinated biphenyls (PCBs), dioxins, and benzofurans.
