Pollution Evaluation of Heavy Metals in Tea and Soil of Tea Plantations in Jinghong City
摘要
Abstract
The contents of As, Pb, Cr, Hg and Cd of tea and soil were studied by methods of field survey from,tea plantation in Jinghong laboratory analysis. Combining with the health quality standard of the tea and soil of tea plantation, the pollution indices were used to evaluate the pollution situation. The results showed that the average contents of the heavy metals were low from tea plantation in Jinghong. Tea heavy metals were lower than the threshold limit value. And heavy metals in the soil reached national secondary standard. The indices were less than 0.6 in single factor pollution index and comprehensive pollution index of tea heavy metals. The tea quality reached national primary standard.Besides the comprehensive pollution index of As was 1.11, the others were all less than 1. 0. The soil was in the safe class or warning class.The soil environmental quality was in clean level or still clean level. It was suggested that tea bases should be selected properly in future when planing non-polluted tea plantation on the whole.关键词
