As the world population and economic development and people's living standards improve, the environment, the type and quantity of pollutants, more and more, especially organic pollutants in the environment. Organic water pollution has become a global issue, not only makes the problem more serious water security, but also on human health poses a serious risk. In environmental monitoring of various chemical substances rapid and sensitive detection for the protection of the environment has a very important significance. At present, China has become the organic contaminants much concern. In this paper, tetracyclines and polybrominated diphenyl ethers in two categories for the study of organic pollutants: (a) establishes a rapid determination of environmental water samples tetracyclines approach. Using ionic liquid [Bmim] PF6 extraction agent, lanthanum rare earth metal ions as a chelating agent, with the temperature as the driving force, liquid-liquid dispersion microextraction, high pressure liquid chromatography and UV detection for quantification. Under optimized conditions obtained wide linear range, low detection limit and good correlation coefficients, and in this section on the basis of the environment in Beijing were detected in water samples. (Two) studied the Zhejiang Taizhou dismantling of scrap electronic equipment to the surrounding crowd breast milk, maternal and infant cord blood PBDEs content and distribution, research whether placental homologue of PBDEs through selective action. The results show that Zhejiang Taizhou breast milk, maternal and infant umbilical cord blood levels of PBDEs in the arithmetic average of 14.05ng / g 1w, PBDEs content level higher than the level reported in Europe (5ng / g 1w), but far lower than the data reported by the United States (35ng / g 1w). The results also show that the baby's umbilical cord blood in the lower brominated diphenyl ethers in maternal blood is higher than, lower than the median of the high maternal bromide, indicating that high-brominated diphenyl ethers difficult to reach the baby through the placenta. Volunteers in the analyzed samples, PBDEs congeners in breast milk, maternal and cord blood in the distribution is different. PBDEs congeners BDE-209 is based, indicating that it can bio-accumulate in the human body. The main ΣPBDEs sample order: ΣPBDEs breast gt; ΣPBDEs maternal gt; ΣPBDEs cord blood. In all samples, BDE-154 and BDE-100 and BDE-99 there is a strong correlation; BDE-153 and BDE-100, BDE-99 and BDE-154 there is a strong correlation; BDE-183 and BDE -153, BDE-154, BDE-100 and BDE-99 there is a good correlation; BDE-183 and BDE-100, BDE-99, BDE-153 and BDE-154 there is a strong correlation; BDE-197 and BDE-100, BDE-99, BDE-153, BDE154 and BDE-183 there is a strong correlation, indicating that human exposure to PBDEs homologues of each route may be the same. Studies have shown that e-waste recycling on the local environment has caused serious pollution of PBDEs, and has affected the entire Taizhou region. If you do not take timely measures, the consequences would be fatal.
