Linking River Health with Urban Drains: the Swan-Canning River Case Study

西澳州Swan-Canning河口的持续恶化引发了识别慢性污染对生物群影响的需要。污染物进入河流的入口已被确定为城市排水沟和赫勒拿河。这项研究的目的是将在“排水鱼”中观察到的影响与在“河流鱼”中观察到的影响联系起来。鱼类健康的生物标志物，如EROD和ECOD活性、DNA损伤、应激蛋白、胆道代谢物等将在排水沟和河流鱼之间进行比较。污染物的化学分析将补充生物标志物的测定。研究结果将适用于整个澳大利亚，并为更好地管理城市排水系统提供信息，以减少其对本地生物群的影响。

The continuous deterioration of the Swan-Canning estuary in WA has triggered the need to identify the effects of chronic contamination on biota. Contaminant entry points into the river have been identified as being urban drains and the Helena river. The aim of this research is to relate effects observed in 'drain fish' to effects observed in 'river fish'. Biomarkers of fish health such as EROD and ECOD activities, DNA damage, stress proteins, biliary metabolites, etc. will be compared between drain and river fishes. Chemical analysis of contaminants will complement biomarker determinations. The outcomes will be applicable Australia wide, and provide information to better manage urban drain systems to reduce their impacts on native biota.
