摘    要:为了解深圳地区贝类麻痹性贝类毒素(paralytic shellfish poison,PSP)染毒情况,对深圳地区主要贝类养殖海域养殖的10种贝类麻痹性贝类毒素染毒情况进行调查。筛选并确定PSP监测指示贝种,进而测定不同养殖海区PSP污染情况。采用AOAC发布的生物法测定麻痹性贝类毒素含量。华贵栉孔扇贝(Chalmys nobilis)和翡翠贻贝(Perna viridis)对PSP蓄积能力强,华贵栉孔扇贝的PSP含量较翡翠贻贝高。确定深圳贝类养殖海域PSP监测指示贝种为华贵栉孔扇贝和翡翠贻贝,全年对两种贝类的PSP监测结果表明PSP含量超过有关标准规定的安全限量的情况时有发生。本研究为实施有效的监测预警管理制度提供了科学依据。

关 键 词:麻痹  贝类  海生毒素类  华贵栉孔扇贝  翡翠贻贝

Abstract:The study was to investigate the poisoned situation of accumulation of paralytic shellfish poison of 10 species of shellfish bred in the coastal water of Shenzhen so as to identify the indicator species of shellfish whose content of the poison can indicate the situation of pollution of water by the poison.Using the biological method(AOAC,15th Ed.,1990),the content of the poison in the samples was determined.Chalmys nobilis and Perna viridis were found to have relatively stronger capability of accumulating PSP than other 8 species of shellfish and Chalmys nobilis accumulated more PSP than Perna viridis.The investigation suggests that the indicator species of PSP in Shenzhen are Chalmys nobilis and Perna viridis,and sometimes the content of PSP in them exceeds the safety limit of related standard within a year.This research provides scientific basis for the effective supervision and management.
Keywords:Paralysis  Shellfish  Marine Toxins  Chalmys nobilis  Perna viridis
