Abstract
Information on organism and population effects was then expanded through the use of toxicity and population modeling. Several toxicity models were evaluated against organism effects of single and multiple exposures and appropriate models were used to expand the analysis of organism effects to additional exposure scenarios. Ceriodaphnia dubia and fish population models were used to evaluate population level and even community level responses to intermittent disturbances. Effects at the population level showed the interaction between species life history and the timing and frequency of disturbance events. Finally, the information from organism testing and population modeling was incorporated into guidance and recommendations for the environmental management and monitoring of episodic pollution events. This guidance included recommendations for the sampling and testing of episodic pollution events. A timescale perspective for selecting exposure appropriate testing methods was proposed, as well a protocol and testing method specifically designed for episodic pollution event analysis.
