Characteristics of heavy metals and their influential factors between sediments and water in summer of the Pearl River Estuary

  • 摘要: 珠江口受复杂径-潮动力耦合作用的影响,河口重金属迁移转化机制复杂多变。本文基于2018年夏季珠江口及其邻近海域海水和沉积物的调查资料,研究了珠江河口多动力因子驱动下7种重金属元素汞、砷、锌、镉、铅、铜和铬的沉积、迁移和积累机制。结果表明:相比于溶解态重金属(水体中)的赋存状况,吸附态重金属(沉积物中)更稳定,污染也更严重;采用皮尔逊相关分析和主成分分析计算出重金属元素与环境因子之间的响应关系,溶解态重金属主要以稀释混合过程为主,吸附态重金属受有机碳和氧化还原作用的影响较大;沉积物-水界面重金属的分配系数显示出铅和铬易被吸附在颗粒物上,而镉和汞易溶解在水体中,揭示了河口复杂动力影响下元素在不同介质的形态转换特征;除了镉-铬、镉-铜和铬-砷这3组元素间不显著相关,其他元素间的显著相关性表明了重金属元素具有相似的来源,并采用主成分分析探讨了重金属元素的潜在来源,主要来源为工业废水,农业和大气沉降次之。研究结果可为有效控制重金属的排放和河口污染治理提供重要支撑。
