摘要
对湛江湾陆源入海排污口海域多环芳烃（PAHs）浓度水平、成分组成、空间分布及来源方面的特征差异进行了研究。结果表明,共15种PAHs单体被检出,3、4环检出率均达100%,其中Ace、Fle、Ant为主要成份。3环单体含量以养殖与农业性质排污口海域最高,工业与商业排污口海域次之,生活与休闲排污口海域最小;4、5环含量表现为工业与商业排污口海域〉生活与休闲排污口海域〉养殖与农业排污口海域,有71.4%工业与商业性质排污口海域有6环单体检出,而ΣPAHs则表现为工业与商业排污口海域〉养殖与农业排污口海域〉生活与休闲排污口海域;聚类分析表明,各排污口海域PAHs有明显差异性。3-5环单体及ΣPAHs的含量与各项环境参数值的Spearman相关性分析结果显示均不存在显著相关。PAHs特征比值显示湛江湾陆源入海排污口海域PAHs来源于石油、石化燃料和植物性燃料的混合源。
The concentration levels,spatial distribution and sources of PAHs in sea water of the land-based outlet of Zhanjiang Bay were studied. The result showed that 15 PAHs were detected,with the ratios of 3-ring and 4-ring PAHs being reached 100%,and the major compounds were Ace,Fle and Ant. Because of the different sewage,in 3-ring PAHs,the outlet in farming agricultural areas had the most content,and the industrial commercial areas and living leisure areas were 2^ndand 3^rdrespectively; As to the 4-ring 5-ring PAHs,the contents of there areas were showed that industrial commercial areas 〉living＆ leisure areas〉 farming agricultural areas. 6-ring PAHs were detected in 71. 4% of the outlets which belong to the industrial commercial areas. The cluster showed that the PAHs concentrations of all the outlets had obvious differences in the nature of the sewage. The Spearman correlation analysis between the concentration of 3 - 5 rings PAHs or ΣPAHs and the environmental parameter values showed not significantly. The characteristic ratios of some certain PAHs suggested that oil,fossil fuels and plant fuels were the dominant sources of PAHs in sea water of the land-based outlet of Zhanjiang Bay.
