It is reported ' Reporter Wang XueFei) Dioxin, kill the intersection of ant and clever many chlorine unite benzene,etc. have a common name - -Permanent organic pollution (POPs) ,It is the biggest kind of pollutant to human survival threat at present. Release recently according to the Science Fundation " Eleven five " The great project guide of the national natural science fund, our country plans to invest 10 million yuan, subsidize the scientist to further investigate environmental course and toxicological effect of the permanent organic pollution in 4 years, offer the basis for the control standard of making relevant pollutant, offer technical support for fulfilling the convention of Stockholm in the country. The permanent organic pollution is that one kind has very strong toxicity, it is difficult to degrade in the environment, can transmit remotely, and accumulate in animal and the human body with the food chain, enlarged pollutant. They not only have the higher one carcinogenic and causing lopsidedly and causing the mutation effect but also can lead to the fact the organism endocrine is disorderly, reproduction, immune dysfunction and other organ pathological changes. The danger of POPs has disguise and sudden, once the great contamination accident happens or crowd's pathological change appears, will produce the calamitous consequence. May 25, 2001, in Stockholm of Sweden, 151 countries including our country have signed " convention of Stockholm regarding permanent organic pollution " together, involve, forbid permanent the intersection of organic pollution and organic the intersection of chlorine and insecticide that use and produce ' DDT, chlorine are red, kill ants efficaciously) , industrial chemical( Six chlorine benzene, much chlorine unite benzene) Burn by product that emerge or with industrial production process ' Dioxin, furan) 12 varieties of 3 kinds. It is reported, will study 4 respect contents in great project entitled environmental course and toxicological effect of the permanent organic pollution of the model: First, study the different kinds of environmental interfaces of permanent organic pollution, especially the absorption, transformation, shape on the little interface change and course dynamics. Second, study absorption in organism it, collect and distribute, can expound permanent the intersection of organic pollution and validity and living beings in the organism utilizing while being rich. Third, transform products as the focal point with model permanent organic pollution and main environment, research pollutant and oxidizing under different conditions of supersession product, reducing, hydrolyze, combine and dynamics course. Fourth, study the union function of low dosage effect and many kinds of pollutant of the permanent organic pollution, adopt various establish the intersection of pollutant and dosage - toxic the intersection of effect and relation,etc. from body and intravital method of testing.
