五垒岛湾海域石油烃分布特征

摘要

This paper researched the distribution characteristics of Petroleum Hydrocarbons (PHs) in Wuleidao Bay ,based on the results of three cruises from May to October in 2014 .The results showed that the range of petroleum hydrocarbon content in surfer water was from0 .012 to 0 .030 mg/L ,with an average value of 0 .021 mg/L ,ranked the Class I water quality according to the standard establish in 1998 .The concentration of petroleum hydrocarbon increased quarter by quarter ,the horizontal distri‐bution has an obvious seasonal characteristic .Compared with historical data found that petroleum hy‐drocarbon concentration was lower than compare area ,to a lesser contaminated .%根据2014年5月、8月和10月3个航次的调查结果，对五垒岛湾海域石油烃污染物的时空分布特征经行了分析。结果表明：该海域石油烃浓度三个季度介于0．012～0．030 m g／L ，平均值为0．021 m g／L ，均达到了一类海水水质标准。石油烃浓度表现出逐季增加的趋势，平面分布具有明显的季节特征。与历史资料对比发现，调查海域石油烃浓度低于比较海域，受污染较轻。
