青堆子湾海水石油类污染物的时空分布及其影响因子
|
摘要
分析青堆子湾及其池塘养殖区石油类污染物季节变化、污染水平及水平分布,探究石油类污染物变化与叶绿素a含量及总溶解无机氮的关系。根据2011年10月至2012年12月4个季度青堆子湾池塘养殖区海域石油类污染物含量的调查结果,对该海域石油类污染物水平进行了评估。结果表明:该海域的石油类污染物含量季节性变化和水平分布变化显著,主要受地表径流和渔船油类排放影响。石油类污染物季节变化与水体总溶解无机氮含量成极显著负相关。整体来看,该海域的石油类污染程度较轻,水质处于国家一类标准。
The seasonal change,pollution level and horizontal distribution of petroleum hydrocarbon in the Qingduizi Bay and its pond aquaculture sea area were investigated and analyzed in this paper,the relationships between petroleum hydrocarbon and chlorophyll a,as well as dissolved inorganic nitrogen were also studied. Based on the investigation results carried out in pond aquaculture sea area of Qingduizi Bay from October,2011 to December,2012,the pollution levels of petroleum hydrocarbon in this sea area were evaluated. The results showed that the seasonal change and horizontal distribution change of petroleum hydrocarbon in this sea area were significant,which were mainly affected by direct surface runoff and oil-discharge of fishing-boat.There was a significant negative correlation between petroleum hydrocarbon and dissolved inorganic nitrogen.Overall,the quality of seawater is in good condition in the studying sea area,which can reach national top-grade level.
