The concentrations of heavy metals and their associated structural deformities in the gills, muscles and hepatopancreas of Scylla serrata from Pulicat Lake were determined and compared with crabs live along Kovalam coast. The concentrations of metals were high in the hepatopancreas and gills of crab from Pulicat Lake, whereas, low in crab from the Kovalam coast. Data were visualized using a principal component analysis (PCA). Significant differences were found for all variables at the plot scale; however, the overall variation was relatively low for muscle tissues in both stations. The structural deformities observed in the gills, hepatopancreas and muscle was due to metal toxicity, and the degree of damage was correlated with the elevated metal concentration. The results showed significant metal accumulation and histo-cytological lesions in the crabs from Pulicat Lake. The results suggest that these biomarkers are useful for assessing the impact of metal pollution in the coastal environments.
测定了普利卡特湖锯缘青蟹鳃、肌肉和肝胰腺中重金属的浓度及其相关的结构畸形，并与科瓦拉姆海岸的活蟹进行了比较。普利卡特湖蟹的肝胰腺和鳃中金属浓度较高，而科瓦拉姆海岸蟹的金属浓度较低。数据通过主成分分析（PCA）进行可视化。在样地尺度上，所有变量均存在显著差异；然而，两个站点肌肉组织的总体变异相对较低。在鳃、肝胰腺和肌肉中观察到的结构畸形是由金属毒性引起的，损伤程度与金属浓度升高相关。结果表明，普利卡特湖蟹体内存在显著的金属积累和组织细胞病变。结果表明，这些生物标志物可用于评估沿海环境中金属污染的影响。
