Research activities in recent years include: natural and anthropogenic sources of trace metals at the local, regional and global scales; potential impacts of global change on metal cycles; processes and mechanisms of cycling of pollutants (especially heavy metals) in air, water and soil leading to human exposure; biomarkers of exposure and effects of metals from analysis of body fluid and tissue samples; trace metals in human oral environment; water quality issues in the Great Lakes; behavior of metal ions and oxyanions in water treatment systems; environmental risk factors for asthma; environmental justice within the community-based research framework; lead pollution and lead poisoning in communities in various parts of the world; chemistry of arsenic in groundwater; dermal and carcinogenic effects of exposure to arsenic in drinking water. Some of the research has been conducted in the developing countries.
