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.

西澳天鹅-坎宁河口的持续恶化引发了确定慢性污染对生物群的影响的必要性。污染物进入河流的入口点已被确定为城市排水沟和海伦娜河。这项研究的目的是将在“排干鱼”中观察到的效果与在“河鱼”中观察到的效果联系起来。鱼类健康的生物标志物，如EROD和ECOD活性、DNA损伤、应激蛋白、胆汁代谢产物等，将在流水鱼和河鱼之间进行比较。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以减少其对原生生物群的影响提供信息。
