David Alvarez, PhD
Dr. Dave Alvarez is a Supervisory Research Chemist at the Columbia Environmental Research Center.
His focus is on the development of innovative methodologies for passive sampler design and complex mixture analysis of various environmental matrices. Research is conducted on emerging and historic contaminants; assessment of the exposure of aquatic and terrestrial organisms and humans to anthropogenic chemicals; and identification of chemicals and their potential sources. The link between chemical occurrence and biological effects are investigated using passive samplers as surrogate biological organisms and screening sampler extracts with in vitro and in vivo tests for estrogenicity, acute toxicity, reproductive and developmental abnormalities. The research is designed to expand the understanding of the roles of physicochemical parameters and environmental factors on the uptake mechanisms of passive samplers. Through our experience and expertise, this research group is recognized as an international leader in the field of passive sampling technologies.
