新乡市两县农村环境土壤卫生监测分析

Analysis on rural environment soil health monitoring in two counties in Xinxiang

目的了解新乡市农村土壤中铅、镉含量,评价农村环境卫生状况,为制定政策措施提供依据和基础资料。方法随机选取两个县40个行政村,每村采集土壤一份,进行土壤颜色、PH值、根系和蛔虫卵等基本卫生学检查,并进行重金属铅和镉的检测。结果两县土壤样本中铅含量均未超过一级土壤标准限值(铅≤35 mg/kg)。土壤中大多数(95%)镉未超过土壤二级标准。但是A县铅、镉含量显著高于B县。在两个县仅仅在一份样本检测到蛔虫卵。结论本次调查两县土壤铅、镉含量未超过国家标准,虽然没有发现明显的污染,但是应该注:意监控。

objective To learn the level of lead,cadmium concentration in soil of rural in Henan Province,and evaluate the rural environmental sanitation,provide the basic data for the policies and measures making.Methods 40 administrative villages in two counties were randomly selected.One soil samples were collected in each village,and the color,pH value,root and ascarid eggs were detected,and the lead and cadmium in soil were detected.Results the lead concentration in all soil samples were less than the first class of soil county standard level（Pb≤35mg/kg）.Most（95%） of cadmium in soils did not exceed the second class of soil level standard.But the lead and cadmium concentration in one country were significantly higher than the other.Just a sample were detected the egg of ascaris lumbricoides.Conclusions Discussion The soil lead and cadmium concentration did not exceed national standards,and there were no obvious contamination.It should be taken care to prevent pollution.
