摘　　要：为研究敌草隆、石油烃对舟山近岸海域生态系统的影响,调查分析了2011-2013年舟山主岛西部近岸海水中敌草隆的含量,同时调查分析了2011年至2012年间该海域中表层海水中石油烃的含量。结果表明,调查海域海水中敌草隆检出浓度范围为<3～52.1 ng/L,平均浓度为<11.1 ng/L。表层海水中石油烃检出浓度范围为0.019～0.244 mg/L,平均含量为0.066 mg/L,未超海水水质四类标准,符合海洋功能区划要求。连续3年调查结果表明,调查海域中敌草隆的含量呈现缓缓上升趋势,对调查海域生态系统的潜在风险有增长的趋势。The diuron pollution level and contents of petroleum hydrocarbons were investigated in seawaters from the west coastal sea area of Zhoushan island from 2011 to 20t3 and from 2011 to 2012, respectively. The results showed that the concentration of diuron in seawaters varies from less than 3 to 52.1 ng/L, the average level of less than 11.1 ng/L. The annual average content were less than 7.9 ng/L in 2011, 13.9 ng/L in 2012, 12.3 ng/L in 2013, respectively. And the concentrations of petroleum hydrocarbon in surface seawaters varied from 0.019-0.244 mg/L, with average concentration of 0.066 mg/L, less than the national Category IV of the seawater quality standard for harbors and marinas. Diuron accumulation in seawaters may present a potential undetermined risk for marine ecosystem in investigated sea aera.
