Dr. Fedoruk holds subspecialty board certification in Medical Toxicology and primary board certification in Occupational Medicine from the American Board of Preventive Medicine. There are fewer than 40 physicians in the U.S. who hold both these certifications. He is also a Diplomate of the American Board of Toxicology (DABT) and is also certified by the American Board of Industrial Hygiene as a Certified Industrial Hygienist (CIH).

Dr. Fedoruk maintains an active clinical practice and is engaged in teaching and research at the University of California, Irvine, where he is Clinical Professor of Health Sciences and Senior Physician at the UCI Center for Occupational and Environmental Health Clinic.

Dr. Fedoruk has extensive experience in the assessment of exposure and related health effects for a broad range of chemical and biological hazards. His 25-year experience involves evaluating health significance from environmental, occupational, and product related exposures. His assessments have involved mercury, lead, arsenic, cadmium, nickel, polychlorinated biphenyl (PCBs), benzene, volatile organic hydrocarbons, isocyanates, pesticides, combustion products, talc, silica, and other dusts. He has designed, developed, and implemented medical monitoring programs for workers in several industries including hazardous waste, energy, asbestos, and electronics, and directed a course on medical surveillance. He performed an assessment of health needs for military and civilian personal involved in chemical weapons destruction in Johnson Atoll, in Micronesia. His work has involved assessment of air quality problems in homes, offices, schools, and work environments including assessments for microbial hazards.

Dr. Fedoruk has served as an advisor on occupational and environmental health matters to both government and industry. He served as a member of an expert panel convened by EPA and the U.S. Department of Labor to develop national priorities for educating health care providers about the adverse health effects of pesticides. Dr. Fedoruk has served as an advisor to NFPA for developing medical guidelines for the Nation’s firefighters. He has assisted health and fire departments in evaluating public health impacts associated with accidental chemical releases. He has also been involved in developing occupational medical programs and guidelines for several jurisdictions, including the City of New York.

Dr. Fedoruk has conducted studies and published articles in the areas of occupational and environmental medicine. He authored chapters in several books, including the World Health Organization’s Encyclopedia of Occupational Safety and Health, the Encyclopedia of Toxicology, and textbooks in occupational lung diseases and thoracic oncology. He was most recently designated as a Fellow of the American College of Medical Toxicology, the society for board certified medical subspecialists.
