摘要
采用GC/MS测定了福建集美养殖区非繁殖期翡翠贻贝(Pernaviridis)体内的16种多环芳烃(PAHs),分析了不同生长期(个体大小不同)翡翠贻贝不同组织中PAHs的蓄积特征。结果表明,翡翠贻贝对PAHs的蓄积量(∑PAHs)为短生长期>中生长期>长生长期;外套膜>内脏团,鳃组织中PAHs波动较大。贻贝易蓄积低环低分子量的PAHs,且随个体增大,各组织中低分子量的PAHs含量逐渐降低,高分子量的略有增加。
The composition and content of PAHs in different tissues and growth stages （different size） of mussels were studied. Sixteen polycyclic aromatic hydrocarbons in green mussels （ Perna Viridis） were detected. The results showed that the some of PAHs （∑PAHs） in green mussles significantly affected on the growth rate （mussels size） and type of tissues： small mussels 〉 middle mussels 〉 big mussels; mantle 〉 visceral mass, while the content of PAHs in gill varied widely. Mussels easier concentrate the low molecular weight of PAHs. With mussels growing, the contents of the low molecular weight of PAHs were decreased, while the contents of the high molecular weight of PAHs were increased slightly.
