摘要
探讨了若干人为因子对长江河口水环境的影响及水生生物资源对水质的指示作用。研究表明,尽管从有关化学指标来看,人为因子对长江河口水质的影响尚限于局部,但许多化合物和潜在的污染物质所产生的有害生物效应浓度往往低于现有的分析能力,因此,必须将污染物、水质、生物诸因素综合考虑,特别注意水生生物本身对水环境变化的响应,才能为水环境保护提供更有效、科学的管理信息。
Possibility of some anthropogenic factors on aquatic environment and bio-monitoring of water quality in Yangtze River Estuary were presented in this study. Based of chemical index, anthropogenic factors influencing water quality was limited. However, the concentrations of many chemical compounds and pollutants are below detection limits of present method. In order to provide appropriate manage information for water conservation, attention must be paid on the effects of aquatic life themselves on the change of environment.
