  1. A framework for assessing public health risks of pesticide-contaminated groundwater.

    Article - En anglais

    The long-term health risk assessments for three commonly used pesticides are presented in this paper.

    These pesticides, alachlor, lindane, and parathion, have been detected in groundwater monitoring wells and are suspected carcinogens.

    A multimedia transport model is employed to predict the long-term fate of these chemicals in the environment.

    Concentrations in each environmental compartment are calculated and wed to determine the dominant exposure pathways and, hence, the dose rate. the public health risk is then quantified using a modified time averaged cancer potency factor.

    The effect of wing the average dose rate over a lifetime (steady-state) as a representative measure of exposure to carcinogens is investigated by comparing the multistage time-dependent low dose excess risk to the constant dose lifetime risk.
