摘要
根据2011年5月(春)和8月(夏)福建省东山湾海洋生态环境的调查数据,研究了海水中溶解态重金属(Cu、Pb、Zn、Cd和Cr_((T)))的平面分布特征及其影响机镧,结果表明:(1)海水中溶解态重金属含量平面分布呈在西南部形成"点源汇集状高值区"且自西向东逐渐递减趋势;除锌元素外,重金属含量季节变化趋势均为夏季>春季。(2)20世纪80年代以来,除海水中Zn含量逐年增加外,Cu、Pb和Cd等污染物含量的变化趋势基本符合倒"U"形环境库兹涅茨曲线。(3)采用数理统计软件分析各溶解态重金属含量之间相关性,春季海水中重金属含量除总铬外,其余4种重金属含量两两呈显著正相关;夏季海水中重金属含量仅Cu-Cd和Cd-Cr_((T))相关性较好。(4)温度、盐度、pH值、化学需氧量、溶解氧、营养盐和生物效应是海水中溶解态重金属含量变化重要的影响因子。
Base on the investigation of Dongshan Bay in May(spring) and August(summer) 2011,the horizontal distribution and its influencing mechanism of dissolved heavy metals(Cu,Pb,Zn,Cd and Cr(T)) in seawater were analyzed.The results indicated that:(1) The distribution of the heavy metals tended to be a peak source in the southwest sea areas and gradually decreased from west to east* whereas the trend of seasonal variation showed that the heavy metal contents in summer were higher than those in spring except Zn.(2) Since 1980 s,changing trend of Cu,Pb and Cd contamination basically showed inverse "U" pattern conforming to environmental Kuznets curves while the content of Zn in seawater increased year after year.(3)The correlations between the dissolved heave metals were analyzed using the ma thematic statistic method.It showed that except Cr_((T)),among the rest 4 heavy metals,each two had a significant positive correlation in spring,while in summer,only Cu-Cd and Cd-Cr_((T)) had a positive correlation.(4) Temperature,salinity,pH,COD,DO,nutrient and the biological effects were the main affecting factors for the variation of dissolved heavy metal contents in seawater.
