渤海湾天津海域贝体调查与评价

Investigation and assessment on seashells of Tianjin nearshore waters in the Bohai Gulf in China

对2012年10月至2013年10月期间,在渤海湾天津海域采集的毛蚶(Scapharca subcrenata)、菲律宾蛤仔(Ruditapes philippinarum)、缢蛏(Sinonovacula constricta)、脉红螺(Rapana venosa)、文蛤(Meretrix meretrix)、牡蛎(Ostrea cucullata)、四角蛤蜊(Mactra veneriformis)和扁玉螺(Neverita didyma)等常见贝类样品生物类、石油类、重金属污染状况进行调查及初步评价。结果表明,化学污染因子石油烃、Cu、Zn、Pb、Cd、Hg、无机As均有残存,生物污染因子粪大肠菌群、腹泻性贝类毒素也均有检出,但含量值较低。总体来看渤海湾天津海域常见贝体没有受到明显污染。

Biological ,petroleum ,heavy matel were investigated in shellfish samples which collected from Oct 2012 to Oct 2013 in Tianjin nearshore waters in the Bohai Gulf in China ,which including Scapharca subcrenata ,Ruditapes philippinarum ,Sinonovacula constricta ,Rapana venosa ,Meretrix meretrix ,Ostrea cucullata ,Mactra veneriformis ,Neverita didyma .The preliminary assessment on the pollution situation of the seashells was made .The results showed that petroleum ,Cu ,Zn ,Pb ,Cd ,Hg , As of chemical pollution factors were tested .Fecal coliform and DSP of biological pollution factors were also positive but the level not high .Generally ,seashells of Tianjin nearshore waters in the Bohai Gulf were not obviously contaminated.
