Human health and ecological risk assessment of soil-borne arsenic and lead: A site-specific risk assessment
- Proctor and Redfern Ltd., Don Mills, Ontario (Canada)
- McMaster Univ., Hamilton, Ontario (Canada)
Screening level site specific human health and ecological risk assessments (ERA) were conducted at a historical (1908--1921) smelting and refining site in the Niagara Region, Ontario in accordance with the recently released provincial and federal risk assessment guidelines. The purpose of the assessment was to evaluate the risk associated with elevated levels of arsenic and lead in surface soils, and to assess alternative remediation options, prior to property transfer. Future intended land use will be parkland and for the site to remain forested. The identification of potential receptors, exposure pathways, and end-points was conducted at the biological community-level. The ERA involved a toxic cue inventory of the core smelting and refining site, adjacent lands and a reference site. Development of remediation options was based on hazard assessment and the prediction of risks associated with arsenic contamination. An evaluation of remediation options and the selection of a preferred option are discussed.
