2006年11月-2007年11月在河北省扇贝养殖区水域设置了9个监测站位进行了7个航次的监测;于2007年5月和2007年8月,在相关7条河流入海河口处设立监测站位,对水和沉积物中油类含量进行了监测.结果表明;河北省扇贝养殖区水域油类污染物的含量范围在0.011～0.520 mg/L,平均值为0.118 mg/L.油类污染的指数范围为0.22～10.4,在对9个站位进行的7航次监测中,71%的站位污染指数大于1.0,尤其是对扇贝生长影响较为关键的月份(2008年5月-2008年10月),所有监测站位的污染指数全部大于1.0;扇贝养殖区7条主要入海河流河口区域油类含量均超过标准.枯水期平均超标指数为10.2,丰水期平均超标指数为18.8;河口区域沉积物中枯水期油类含量均值为777,高于国家标准1.55倍,枯水期油类含量均值为473,低于国家标准浓度限值.大陆径流是造成河北省扇贝养殖区油类污染的主要因素.

Nine inspecting stations were set up in scallop cultivating sea area and inspections of seven sailing-times were made in Hebei Province from November,2006 to November,2007. In May,2007 and August,2007,inspecting stations were set up at the estuary of seven related rivers in order to inspect the oil content of the water and deposit. The results show that the oil content of the water and deposit ranges from 0.011 mg/L to 0.520 mg/L,the average is 0.118 mg/L,the pollution index of the oil ranges from 0.22 to 10.4,and the pollution index of the oil is higher than 1.0 in 71 percent of the inspecting stations,especially in the crucial months when scallops grow rapidly. From May,2007 to October,2007,the pollution index of the oil content is higher than 1.0 in all of the inspecting stations,and oil content at the estuary of seven main rivers in scallop cultivating sea area exceeds the national standard. The average index of exceeding standard in the low-water season is 10.2,and that in high-water period is 18.8. The oil content of the deposit at the estuary in the high-water period averages 777,which is 1.55 times higher than the national standard. In contrast,that in the low-water period is 473,which is lower than the national standard. The land river is one of the main factors to result in the oil pollution in scallop cultivating sea area in Hebei Province.
