Otherwise, just place your mouse cursor over the steps listed below for more detailed information. This is not an updated version of this page but it will give the user a general idea of its function. A project is an individual site-specific assessment. In the WCEM, all wildlife and contaminant scenarios in a particular assessment are accessed and linked via the Project Manager. The species selected may represent an important role in the community structure, be more likely to contact the contaminant because of diet, habitat preferences or behaviour or be a species of concern in the assessment area.
Weight varies with season, gender, age and health of an individual.
Therefore it is important to choose a weight representative of assessment concerns. The diet represents wildlife exposure via the food chain. It is important that the diet be tailored to the site and the requirements of the assessment. The WCEM converts daily energy requirements based on weight to grams of each diet component. Step 5 Exposure routes considered include inhalation and ingestion of water, food, soil and sediment.
