Background technology
From the 50's of 20th century since Kumamoto County, Japan finds the first methylmercuric poisoning event, different research fields
Scholar all give highest attention to mercury pollution problem.Mainly there are three aspects in the source of mercury in soils: 1) the natural of hydrargyrum is released
Put, including volcano and geothermal activity, the transpiration of soil, natural water and plant surface, forest fire and rock decay
Deng.The mercury pollution that this natural cause causes generally accounts for the 1/4 of mercury emissions total amount.2) artificial pollution, mostlys come from sewage and fills
Irrigate, hydrargyrum smeltery and the discharge of mercurial factory (chlorine industry, electrical equipment, instrument)；Unreasonable in agricultural tilling use mercurous fertilizer
Material and pesticide etc..3) dried wet deposition, in air, mercurous waste gas is deposited to soil, is also an important sources of Mercury in Soil.Hg
Bio-toxicity more significant, its heavy metal ion will produce toxicity when mass concentration is 0.001 ~ 0.01mg/L.
Soil around hydrargyrum smeltery and mercurial factory etc., due in the waste gas of the discharge such as hydrargyrum smeltery and mercurial factory
Containing a large amount of hydrargyrum, waste gas runs into rainwater and is deposited to ground, causes Soil Mercury Pollution serious.
One bio-engineering research team of university of Pan American Puerto Rico of the U.S. injects two in a kind of angstrom Xi Shi escherichia coli
Plant " parent's hydrargyrum " gene.This transgenic escherichia coli has extraordinary effect to the process of hydrargyrum.At present, by microbial immobilized
Technology obtains paying close attention to widely, such as Patent No. both at home and abroad: describe a kind of fixing in 200910056687.X patent specification
Changing microorganism preparation method, immobilized microorganism is mainly characterized by Microorganism incubation and becomes a kind of solid-state, is placed in sewage and has
