Pollutim Evaluation of Heavy Metals in Soil of Tea Plantations and Tea at Emeishan and Jiajiang
摘要
Abstract
Objective] The aim was to study heavy metal content in soil of tea plantations and tea at Emeishan and Jiajiang ,and evaluate the pollution degree.[ Method] Thecontent of Cu,Cr,Pb,Cd,As and Hg were determined by atomic absorption spectrophotometry and atomic fluo-rescence spectrometry,based on “GB15618 -1995” of “soil environmental quality standard”, the single factor pollution index and compre-hensive pollution index were used to evaluate the soil samples in tea plantation.[Result] The results showed that the average content of Cu, Cr, Cd, Pb, As,Hg were 30.59、67.08、0.35、24.15、13.32 and 0.13mg /kg in soils of the tea plantations, according to the national stand-ard GB15618 -1995 soil environmental quality secondary standard values, Cd in a critical level, and the single pollution index of Cu, Cr, Pb, Hg, as were less than 1.0, it belongs to the level of security.Based on GB2762-2012/NY659-2003 /NY/T288-2012 , the contentof Cu, Cr, Cd, Pb, As, Hg of tea samples of raw materialswere obtained in the five sampling point .The contents were much lower than the na-tional standard or issued by the Department of the highest content limit.[Conclusion]The heavy metals content of Emeishan city and jiajiang county are safe and accord with national standard.关键词
