Inspection And Evaluation On Huat'an Agricuiture Environment Condition And Agriculture Products Quality

In order to developthe production of none-polluted agricultural products,green food and organic food,in 2002 and 2003,we have evaluated the quality of seven agricultural main water sources (such as Hongze Lake etc.)in Huai'an villages and towns;the heavy metal content and pesticide remainder of 53 soil samples in seventeen Huai'an villages and towns and of 51 samples of rice , wheat, vegetable,melon,fruit and bean as well.To compare the evaluation results with national/international standards: GB15618-1995, DB32/T343-1999, NY/391-2000 and NY/T271-1955, the conclusion is as following:1 The water quantity analysis of Huai'an agriculture water sources shows that the hydrargyrum, cadmium , lead, six valence chrome and chlorid content in the water are equal or lower than that of national third scale standard for surface water.2 The analysis of agricultural irrigation water quality shows that the content of hydrargyrum,cadmium,lead,six valence chrome and chlorid in the water agrees with the requirement of DB32/T343-1999 for agriculture irrigation water.3 Except the two sides of Qingan River,the soil is in good condition with integrate pollution index lower than 1. If operate as per production regulation,qualified non-polluted agricultural products can be produced.4 The detection rate of r-BHC (benxene hexachloride) in the grain is 24.0%,which is within the range of standard,other BHC isomers are not detected;No BHC in vegetables;No DDT in grain and vegetables;The total detection rate of 4 types of organic phosphor pesticides is 31% in the grain and vegetables,within which the content of dichlo rovinyldimethy 1 phosphate and dimethoate is a little bit higher than the standard,but the content of Baytex and Sunithion is lower than the staneard.5 The heavy metal detection rate in the grain and vegetables are stated respectively as following:Arsenic:none,none; Chrome:8%,72.4%; Lead:6%,13%;Cadmium:none,none; Hydrargyrum :none,none.The content of heavy metal in agricultural products agrees with the requirement for non-polluted food.
