Pollution Situation Assessment of Heavy Metal in Part of Leaf Vegetables in the Area around Poyang Lake
摘要
Abstract
[Objective] The aim was to evaluate the heavy metal pollution to some vegetables and plants in Poyang lake and also to analyze the causes. [Method] By determining the heavy metal content in Pb,Cd,Cr,Cu,Zn in the vegetable bases in eleven counties and three kinds of vegetables in farmland,the pollution of heavy metal was illustrated. The causes of heavy metal pollution in Poyang Lake were further discussed through comparing two sources of vegetable in Poyang Lake. [ Result] Results showed that 2/3 of leaf vegetable samples in Poyang Lake area of heavy metals exceeding the rate was over 50%. Pb in cabbage exceeded the most seriously with excessive rate 85.2%. Single - factor pollution index showed that the degree of pollution of the vegetables in the Poyang Lake area was low,of which 66.9% were safe and fine . Celery was contaminated in the greatest extent by Cr、Pb. In both cropping patterns,the level of heavy -metal contamination of vegetables in vegetable base was higher than farms. [ Conclusion] Heavy metal pollution in vegetables had initially caused by the strong development of industrial and traffic of economic zone of Poyang Lake. Residents around Poyang Lake were suggested to reduce consumption of celery and vegetables of base or in an appropriate amount to decrease the health risks.关键词
