摘要
根据调查分析了渤海海域石油烃污染状况,建立了渤海石油烃多介质动力学模型,估算了渤海海域石油烃污染物环境容量和剩余环境容量.结果表明,调查海域石油烃平均浓度为(25.7±13.6)mg/m3,变化范围为4.4～64.8 mg/m3,其中,莱州湾,渤海湾等近岸海域污染较严重.在一、二类国家海水水质标准下,渤海海域石油烃污染物环境容量(ECo)为29 169 t/a,在三类国家海水水质标准下ECo为177 306 t/a,在四类国家海水水质标准下ECo为298 446 t/a,各海域在一、二类国家海水水质标准下石油烃污染物环境容量分别为,渤海湾5 255 t/a,辽东湾8 869 t/a,莱州湾4 889t/a,渤海中部10 156t/a.
The pollution condition with respect to petroleum hydrocarbon associated with oil pollutant (PHAOs) is summarized in Bohai Sea in this paper. The results show that the mean concentration of PHAOs is (25 .7 ± 13.6)mg/m , varying from 4.4 to 64.8 mg/m in the survey sea area. Laizhou Bay and Bohai Bay were contaminated badly in shore. The dynamic model for distribution of marine PHAOs among multimedia environment in Bohai Sea has been established. The environmental capacities ( ECo) and surplus environment capacities ( SECo)of water with respect to marine PHAOs has been estimated in Bohai Sea according to the dynamic model. The results show that the ECo separately are 29 169 t/ a, 177 306 t/a and 298 446 t/a for the first,second and third , fourth seawater class quality standards. And the ECo of Bohai Bay, Liaodong Bay, Laizhou Bay and Central Bohai Sea are 5 255 t/a, 8 869 t/a, 4 889 t/a and 10 156 t/a respectively for the first and second seawater class quality standards.
