CRIER, a relative analysis tool for preliminary screening of complex industrial waste and effluents
- Concordia Univ., Montreal, Quebec (Canada). Ecotoxicology Program
CRIER (Chemrisk, a Relative Index for Evaluating Risk), a Windows{trademark}-based program for the preliminary screening of potential risk to aquatic ecosystems, has been developed at the Center of Environmental Chemistry and Ecotoxicology (CECE) in Concordia. This tool, originally designed for environmental management government bodies, was designed to screen chemical compounds found in industrial aqueous effluents, for their potential to cause harm to some selected target species such as the rainbow trout (Oncorhynchus mykiss). This revised model will be applicable in both regulatory and industrial managements as an expert system that provides an assessment based on the most up-to-date toxicological information regarding each compound. Some major characteristics include the consideration of partitioning, plume effect, bioavailability and bioconcentration capacity in producing an evaluation of potential for harm to freshwater species. When parameters are empirically unavailable from the diverse databases, QSARs are used to produce theoretical preliminary estimates of the missing values. one aspect of the model allows consideration of the combined toxicity of organic congeners. Case studies are used in demonstrating the capacities of this model.
