What's in our water ? Bioanalytical tools for assessment of micropollutants, mixtures and transformation products

Motivated by the experience with the mixtures we propose an algorithm to derive effect based trigger values for diverse types of water. The trigger values are based on existing individual chemical’s water quality guideline values and if the numerical values exceed the set values for each type of water, then further investigations using other endpoints or chemical analysis are prompted. These proposed trigger values account for mixture effects and large numbers of chemicals in a water sample. There is not a single trigger value but for each mode of action and associated endpoint, a trigger value must be derived.
