Abstract:
Objective To investigate the organic pollutants in the contaminated water irrigation area soil and to study the lipid peroxidation effect of the pollutants on mouse. Methods The organic pollutants of the polluted irrigation soil and control soil were extracted using the supersonic oscillator. The ingredients of the organic pollutants were measured by the GC-MS spectrum. The 40 sanitary Kunming mice were randomly divided into five groups: the dimethylsulfoxide control group,low dose group of control soil,high dose group of control soil,low dose group of polluted soil,high dose group of polluted soil. The administered doses of the low and high dose groups were 25.5 g dry soil/kg body weight per day by oral for two weeks. The activities of T-SOD,GSH-Px and the content of MDA in serum of mice were determined. Results Phenanthrene,yrene,diphenyl,fluorene,naphthalene,dimethyl-naphthalene,2,3,6-trimethyl-naphthalene,anthracene,dimethyl-anthracene,1,4-dimethyl-anthracene,fluoranthene,4-methyl-pyrene,dibenzothiophen,4-methyl-dibenzofuran,dibenzofuran,butylated-hydroxytoluene,dodecane,neopentyl-cyclohexane,trimethyl-heptane,1,2-dimethyl-cyclohexanimine,butethal were detected in the polluted irrigation soil and their levels were 14.3,2.1,1.3,1.1,0.8,1.3,0.4,2.9,7.2,2.3,9.1,0.2,0.4,1.4,1.7,0.37,0.9,0.11,0.02,0.02 and 0.13 mg/kg respectively in the polluted irrigation soil. Trimethyl-heptane,dimethyl-heptane and 1,2-dimethyl-cyclohexanimine were detected,and their levels were all 0.01 mg/kg in control soil. Compared with the solvent of dimethylsulfoxide group,the activities of T-SOD and GSH-Px of the high dose group of control soil and two dose groups of polluted soil all decreased,the differences were all significant(P0.05). Conclusion The soil has been contaminated with organic pollutants in the investigated area and the soil extract may produce a certain effect on lipid peroxidation in mice.
