为研究敌草隆对舟山近岸海域生态系统的影响,自2011年至2013年对舟山主岛西部近岸海域沉积物中敌草隆的含量进行了调查。对30个沉积物样品进行分析检测,调查海域沉积物中敌草隆的含量(干重)范围为未检出~3.9×10-9,平均含量为1.13×10-9,大部分样品含量低于1.43×10-9(占总样品量的86.7%)。其中,年均含量分别为2011年0.851×10-9,2012年1.328×10-9,2013年1.202×10-9。沉积物中敌草隆的含量呈现缓慢上升趋势,表明敌草隆对调查海域的生态系统存在潜在的风险。
In order to study the influence of diuron on the ecosystem of Zhoushan coastal waters, the content of diuron in the sediments of the western coast of the main island of Zhoushan from 2011 to 2013 was investigated. Thirty sediment samples were analyzed for detection. The contents of diuron (dry weight) in the sediments from the survey area ranged from undetected to ~ 3.9 × 10-9 with an average content of 1.13 × 10-9. Most samples were low in content At 1.43 × 10-9 (86.7% of the total sample size). Among them, the average annual contents were 0.851 × 10 - 9 in 2011, 1.28 × 10 - 9 in 2012 and 1.202 × 10-9 in 2013 respectively. The diuron content in sediments showed a slowly increasing trend, indicating that Diuron potential risk to the ecosystem of the surveyed waters.
