Prop. 65 Technical Support

Solar Collection Facilities, Various Sites, California
Iris Environmental conducted a human health risk evaluation on behalf of a manufacturer of cadmium telluride thin film photovoltaic cells.

Iris Environmental developed a conceptual site model (CSM) of potential release mechanisms of cadmium and tellurium from the photovoltaic cells, transport mechanisms, and potential human exposure routes over the entire life cycle of the photovoltaic cells, including in small-scale residential and large-scale commercial installations. Iris Environmental quantified potential chemical exposures in the context of Proposition 65 safe harbor levels, and quantified cancer risks and noncancer hazards in the context of a human health risk assessment.
