摘要:
采用超高效液相色谱-串联质谱法, 对山东东营潮河入海口邻近海域海水、沉积物及贝类体内氨基脲污染状况进行了调查研究。结果表明, 潮河入海口邻近海域海水中氨基脲的浓度为0.18—70.6μg/L, 沉积物中浓度为0.26—18.9μg/kg, 生物体内含量为0.82—6.46μg/kg, 与作者调查的其它海域相比, 污染最为严重。氨基脲在潮河口邻近海域海水、沉积物和生物体内浓度都沿潮河向下呈放射性递减分布, 说明潮河是污染的主要来源。本研究同时对不同品种生物体对氨基脲富集差异进行了比较, 发现不同品种生物体对氨基脲的富集能力不尽相同。

Abstract:
Semicarbazide in coastal waters adjacent to the Chaohe River estuary was analyzed in our work. The concentration of semicarbazide is 0.18—70.6μg/L in seawater, 0.26—18.9μg/kg in sediments and 0.82—6.46μg/kg in marine organisms. The levels of semicarbazide in coastal waters adjacent to the Chaohe River estuary are quite higher than those of other locations. The concentrations of semicarbazide in seawaters, sediments, and seashells decreased gradually and present radial distributions along the Chaohe River, indicating that the Chaohe River is the main pollution source. We also studied accumulation of semicarbazide in different kinds of seashells.
