湄洲湾海域贝类重金属污染状况及健康风险评价
Heavy Metal Pollution and Health Risk Assessment of Shellfish along the Coast of Meizhou Bay
摘要
Abstract
[Objective]To investigate heavy metal pollution situation of shellfish and assess the health risk to people after shellfish consumption.[Method]Pb, Cd, As, Cr, Hg, Cu contents in Crassostrea gigas,Sinonovacula constricta,Ruditapes philippinarum,Scapharca subcrenata and Meretrix meretrix from Meizhou Bay were measured. A pearson correlation analysis on different heavy metals against different shellfishes was implemented based on the analysis data. Single pollution index and comprehensive pollution index were adopted to evaluate the health risk of five shellfish.[Result]There was distinct positive correlation between Hg and Cu (P<0.05) with a correlation coefficient of 0.923, while there was no significant correlation among the other elements. All the contents of Pb, Cd, inorganic As, Cr, Hg, Cu did not exceed the corresponding limit values of food. The comprehensive pollution indexes in five kinds of farmed shellfish were in the range of 0.28-0.35. The TTHQ values were in the range of 0.370-0.532, less than 1.[Conclusion]The five kinds of shellfish had not been polluted by heavy metal. Their consumption should pose a low health risk for heavy metal exposure.关键词
