中文摘要:

      目的 掌握辽宁省某市河蟹养殖环境污染情况并提出安全预警。方法 监测某市河蟹养殖环境和河蟹产品中石油烃含量, 剖析石油烃污染来源并提出治理措施。结果 水质中石油烃总平均值为0.056 mg/L,底质中石油烃总平均值为19.59 mg/kg, 河蟹中石油烃总体均值为7.27 mg/kg, 超标率为4.9%。结论 河蟹养殖水质总体上已受到石油烃污染, 底质也对石油烃有一定的蓄积, 环境中石油烃污染对河蟹产品已产生一定的影响。政府有关部门可以通过切断石油烃污染来源, 加强监管等措施来减轻石油污染, 减少对河蟹养殖环境和河蟹产品的影响。

英文摘要:

      Objective To master the pollution situation of the crab breeding environment in a city of Liaoning province and put forward the safety warning. Methods Petroleum hydrocarbon content was determined in crab breeding environment and river crab products from the city. The sources of petroleum hydrocarbon pollution were analyzed and the control measures were put forward. Results The general average value of petroleum hydrocarbon in water was 0.056 mg/L, and the total mean of petroleum hydrocarbon in the sediment was 19.59 mg/kg. The total mean value of petroleum hydrocarbon in the river crab was 7.27 mg/kg, and the exceeding standard rate was 4.9%.Conclusion In general, the water quality of river crab breeding has been polluted by petroleum hydrocarbon, and the sediment also has a certain accumulation of petroleum hydrocarbon. The pollution of petroleum hydrocarbon in the environment has had a certain effect on the river crab products. The government departments can reduce the oil pollution by cutting off the sources of oil pollution and strengthening supervision, so as to reduce the impacts on the river crab breeding environment and the river crab products.
