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.

西澳斯旺坎宁河口的持续恶化引发了确定慢性污染对生物群影响的需要。已确定污染物进入河流的点是城市排水沟和海伦娜河。本研究的目的是将“排水鱼”中观察到的影响与“河鱼”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、胆汁代谢物等，将在排水系统和河流鱼类之间进行比较。污染物的化学分析将补充生物标志物的测定。研究结果将适用于澳大利亚全境，并提供信息以更好地管理城市排水系统，以减少其对本地生物群的影响。
