英文摘要Research of surface sediments from intertidal zone of Dagu estuary in Qingdao was carried on at the end of October in 2014 and the end of July in 2015. The content of mercury and arsenic of 15 surface sediments in dry season and 45 surface sediments in wet season was determined,and the contamination assessment was conducted. Results showed that the content of arsenic in dry season satisified Class Ⅱ of Marine Sediment Standard,while the content of arsenic in wet season satisfied the Class I. The content of mercury satisified the Class I of Marine Sediment Standard both in dry and wet seasons. The contamination assessment was conducted with geoaccumulation index (I_(geo))and potential ecological risk index (E_r~i). Results demonstrated that the arsenic of surface sediment in dry season was mild to moderate polluted,and the mercury was unpolluted to mild polluted. The arsenic of surface sediment in wet season was unpolluted,and the mercury was also unpolluted to moderate polluted. The potential ecological risk level of arsenic in dry season was mild to moderate,while that in wet season was mild. The potential ecological risk level of mercury was mild to high in both seasons.
中文摘要2014年10月底和2015年7月底对青岛大沽河口潮间带表层沉积物进行了2个航次的调查,测定了15个枯季表层沉积物样品和45个洪季表层沉积物样品中砷和汞的含量,并进行了污染评价分析。结果表明,枯季表层沉积物中砷含量基本都超过第一类海洋沉积物质量标准,符合第一类海洋沉积物质量标准,而洪季表层沉积物中砷含量符合第一类海洋沉积物质量标准。枯季和洪季表层沉积物中的汞含量均符合第一类海洋沉积物质量标准。采用地累积指数法(I_(geo))和潜在生态危机指数法(E_r~i)对该区域表层沉积物中的砷和汞进行污染评价。结果表明,枯季表层沉积物中砷属于轻度~偏中度污染,汞属于无污染~轻度污染;洪季沉积物中砷基本无污染,汞属于无污染~偏中度污染。枯季表层沉积物中砷的潜在生态危害程度为轻微~中等水平,汞的潜在生态危害程度为轻微~较强水平;洪季表层沉积物中砷的潜在生态危害程度为轻微水平,汞的潜在生态危害程度为轻微~较强水平。
