摘要
采用气相色谱-质谱联用仪（GC-MS）对2009年4月从天津临港工业区周围海域获得的生物样品进行了测试,研究了该区生物体内DDTs和HCHs含量及分布特征。结果表明,该海域生物体中DDTs的含量相对较高,范围为1.15~25.79 ng.g-1（湿质量）,HCHs含量较低,范围为0~7.86 ng.g-1（湿质量）。异构体分析显示有新的DDTs和HCHs源输入,生物体内DDTs和HCHs含量均未超过海洋生物质量国家标准,但生物样品中DDTs组份都已超过USEPA制订的野生动物质量基准,要严格控制三氯杀螨醇和林丹的使用,保护该海域生态环境。
Concentrations and distributions of DDTs and HCHs in organisms from Tianjin harbor industrial park in Bohai Bay in April,2009,were quantitatively analyzed by GC-MS.The results showed that the content of DDTs in organisms from Bohai Bay was greater than HCHs and the concentrations were in the range of 1.15-25.79 ng·g-1（ww） and 0-7.86 ng·g-1（ww）.The isomer analysis showed that there were new sources of DDTs and HCHs.The content of DDTs and HCHs in organisms is not exceed the national standard,but the content of DDTs in organisms exceeded the corresponding quality control standards of USEPA.The usage of dicofol and lindane should be strictly controlled to protect from ecological environment in Bohai.
