摘要
Inductively coupled plasma mass spectrometry is used to detect Cdforbenthos in the artificial reef .The results show that： Cd of benthos is varied from0.011μg/L to 0.541 μg/L, and averages 0.188 ± 0.220 μg/L. The distribution of Cddecreased in the order： gonads〉 gills〉 muscle in different tissues. The enrichmentregalurity in muscle Cd of different benthos was Oratosquilla, crab, fish, shrimp,ocellatus. Its health risk factor is far less than 1, indicating that Cd hasn’t obvious healthrishks on exposure population.
采用电感耦合等离子体质谱法检测人工鱼礁区内底栖生物体内Cd的含量。结果表明:底栖动物Cd的含量为0.011-0.541μg/L,平均值为0.188±0.220μg/L。Cd在不同生物组织器官中的分布按顺序依次为:性腺>鳃>肌肉。不同生态位底栖生物肌肉中Cd的富集规律为:口虾蛄,蟹类,蝦虎鱼类,虾类,头足类。其健康风险因子远小于1,表明镉对接触人群没有明显的健康风险。
