Unformatted text preview: future. Then for toxicity assessment you would evaluate how badly the chemicals you think will affect those populations based upon the likelihood of transport through the environmental pathways and exposure frequency evaluated in the previous step. Finally, you will combine the data to determine how much of a risk each one of those chemicals would pose to the populations. Ideally your site should have properties such as a low water table, which would make it harder for the chemicals to move from the site and therefore lowering the risk that it will affect populations. 14-13 Background risk is the risk that someone is exposed to in the absence of the particular variable causing risk being studied. Incremental risk is increase in risk caused by the variable of interest. The total risk is the sum of the background and incremental risk....
