Soil is contaminated, plant root is damaged, hinders the breathing and absorption of root, cause Plant death；Arene material is to people and animal
Toxicity is larger, if contacted through long period larger concentration, can cause the symptoms such as nausea, headache, dizziness；In addition, in oil
Multiring aromatic hydrocarbon substance has strong three-induced effect.The hydrocarbons such as the crude oil of leakage such as naked light, can cause fire incident；
If the hydro carbons of leakage enters in restricted clearance, VOC reaches LEL, easily explodes, or even causes the dead group's wound of group
Catastrophic failure occurs.Soils and sediments be hydrocarbons pollutant absorb, the main medium of migration and accumulation, in water body, air
Hydrocarbons pollutant can by different approaches enter soils and sediments in, the hydro carbons in soils and sediments can also pass through the earth
Chemical cycle enters in water body and air and causes secondary pollution.
In addition, with the development of recent decades process of industrialization, various industry are such as the institute such as mining industry, Metallurgy Industry, chemical industry
Caused waste water and the leachate of solid waste are directly entered water body, enter soil with the distribution of water system, cause soil weight
Metallic pollution is in increased trend, heavy metal pollution of soil not only bring huge economy because directly contributing grain drop in production year by year
Loss, and be finally detrimental to health through the media such as water, air, plant or food chain.More seriously heavy metal-polluted soil
Pollution has chronicity, disguise and irreversibility, and therefore, the reparation to heavy metal pollution of soil is extremely urgent.
