The Evaluation Of Environment Quality Detection And Analysis Of Vegetable Production Areas In Urumq

In order to anaLyze and assess the environmentaL quaLity of the vegetabLe base of Urumqi City, according to the nationaL standard, the main vegetabLes growing area of atmospheric environment, heavy metaLs in farmLand irrigation water and farmLand soiL and the production of vegetabLe products and harmfuL substances and pesticide residues and other indicators, according to the standard quasi provisions were distribution, sampLing, testing, anaLysis of its poLLution degree, and anaLysis of poLLutant source and poLLution ways, to the deveLopment of non poLLution vegetabLes production to provide a scientific basis for using singLe poLLution index method and comprehensive poLLution index method.The resuLts showed that the totaL content of 6 items in Urumqi city was determined by 5 test points, and the average vaLue of the content of nitrogen oxide was 0.024mg/L; the average vaLue of 0.56 mg/L was 0.035 mg/L, the average content of totaL suspended particuLate matter was 0.20 mg/L, the average vaLue of Lead content was 0.0038 mg/L, and 5 kinds of poLLutants were in standard Limits.8 irrigation water testing points were detected in 9 projects, the project of arsenic, Lead, cadmium and oiL 4 projects are not detected in the numericaL. The average mercury content was 0.00015mg/kg, the average vaLue of six vaLence chromium was 0.009mg/kg, the average vaLue of chLoride was 83.7mg/kg, the average vaLue of fLuoride was kg 2.02mg/, the maximum of pH was 8.68, the minimum vaLue was 7.43. The detection resuLts of 9 kinds of poLLutants have a detection point pH vaLue exceeds the nationaL Limits, and the remaining items are not exceeded the Limited standard.8 of the farmLand soiL testing points were detected in 7 projects six six six, two items of basic DDT pesticide residues were not detected in the numericaL. The average totaL mercury was 0.026mg/kg, the average vaLue of chromium was 18.7mg/kg, the average arsenic was 6.3mg/kg, the average vaLue of cadmium was 0.43mg/kg, the average Lead was 12.5mg/kg, and the average vaLue was.The test resuLts showed that the quaLity of the vegetabLes in the four districts of Urumqi city was in accordance with the requirements of the nationaL standard of environmentaL poLLution, and it couLd be pLanted in the vegetabLe. The irrigation water is basicaLLy in Line with the requirements of the state of the environment of the non poLLution vegetabLes. The infLuence of chLoride on irrigation water is the biggest, which mainLy comes from industriaL waste water and domestic sewage. The soiL is basicaLLy in Line with the requirements of the nationaL environmentaL poLLution, and the DeveLopment Zone (Toutun River area) of the two detection point of soiL cadmium content is sLightLy higher than the nationaL standard, shouLd be recommended for the region's soiL environment monitoring, and for cadmium poLLution, to find the source of poLLution, the system set up effective management pLan, the controL effect of tracking and monitoring.
