Goal: To quantify the levels of speciated ambient Hg and Hg deposition (wet and dry) at two sites: Chicago, IL and Holland, MI; to investigate the transport, transformation and deposition of Hg from an urban source region to downwind receptor locations across southern Lake Michigan; to determine the spatial and temporal scales for speciated ambient Hg transport and chemistry downwind from an urban.. >> more

Lead exposure poses a major environmental health problem in India. No direct studies have yet been performed in India to investigate the impact of lead exposure on outcomes such as neurobehavioral development. We propose to build upon a collaborative effort initiated during the proposed PI's work as a Senior Fulbright Scholar and work with colleagues at the Sri Ramachandra Medical College and Research.. >> more

Creation of an adaptive multimedia model determining intake fractions at local (1km grid around the emission source), regional (200km grid within the continent of emission) and continental (world divided in continents) levels. Special emphasis is given to further develop modeling of exposure in the food chain linked to highest intake fractions and high level of uncertainties. This research builds up.. >> more

This project first seeks to characterize the different redox environments that are established and maintained within the intact rat and mouse conceptus (embryo proper and associated extraembryonic membranes). Concentrations, redox potentials, and flux for redox couples that make up the major redox circuits such as glutathione (GSH)/glutathione disulfide (GSSG), cysteine (cys)/cystine (cySS), and thioredoxin-reduced.. >> more

The burden of childhood asthma disproportionately affects children living in poverty and in urban centers, many of whom are minority ethnic groups. For those living in urban environments with high traffic densities, there is increasing concern about potential adverse respiratory health effects of exposure to diesel and other vehicular exhaust. Epidemiologic studies have shown associations between.. >> more

Leader: Jerome Nriagu (Ph.D., D.Sc.)
Prof. Nriagu's research and teaching programs center around three main issues: (i) sources, behavior, fate and effects of metals in the natural and contaminated environments; (ii) environmental justice and disproportionate exposure of communities to environmental pollutants; and (iii) environmental health problems in the developing countries. His work includes applied laboratory and field studies and.. >> more
