Experience Summary: Dr. Sidney J. Marlborough III, is a Senior Environmental Health and Safety Manager with Continental Carbon Company in Katy, Texas. He is responsible for the corporate chemical stewardship program and is responsible for the risk evaluation of new products for oil and gas exploration and production. He has over 20 years of experience in environmental risk management, toxicology, risk assessment, litigation, and research. He has worked for state government, academia, private consulting, and chemical industry. He has developed numerous human health and ecological risk assessments for expert reports and remedial cleanup requirements. He has studied the toxicity of metals, chlorinated solvents, endocrine disruptors, poly-aromatic hydrocarbons, and pesticides in both human and ecological receptors. Dr. Marlborough has developed an uptake kinetic model simulating the phytoremediation of arsenic with various plant species. He has developed formulas for the extrapolation of toxicity of arsenate and arsenite as part of ecological risk assessment. He has conducted published research in the areas of marine toxicity to benthic invertebrates, arsenic speciation toxicity in ecological receptors, TNT exposure to benthic fish, phytoremediation of metals, and microsatellite instability in squamous cell carcinoma.
