TCEQ Toxicity Factors and Protection of Human Health

Questions and answers about TCEQ derived toxicity factors and how they are used to protect public health.

NEW The TCEQ Environmental Health Update (TCEQ publication GI-450) has been posted

Extremely! The TCEQ’s toxicology staff consists of nine Ph.D.- and four master’s- level scientists, including one certified by the American Board of Toxicology. Two are also OSHA HAZWOPER certified.
The Toxicology staff collectively has over 150 years of scientific experience.
TCEQ toxicologists are active in several professional societies including the American Conference of Governmental Industrial Hygienists, the American Public Health Association, Dose Response Advisory Committee, the Alliance for Risk Assessment, the Society for Risk Analysis, and the Society of Toxicology.
The Toxicology Division has been awarded multiple grants and participated in several collaborative research projects:
◦Hillcrest Community Environmental Investigation — A two-year environmental investigation of ambient air, soil, and groundwater designed in collaboration with the local community to address its concerns about neighboring petroleum refineries, October 2012.
Midlothian, TX Ambient Air Collection and Analytical Chemical Analysis — A year-long ambient-air-monitoring study designed in collaboration with the local community to address its concerns about neighboring point sources, July 2010.
Houston Exposure to Air Toxics (HEATS) — Collaborative research among the TCEQ ($400K from a U.S. EPA grant awarded to the TCEQ, $476K from the TCEQ), the Mickey Leland National Urban Air Toxics Research Center ($275K), the Texas Environmental Research Consortium ($50K), and the East Harris County Manufacturers’ Association ($50K); a research grant awarded to the University of Texas School of Public Health for a two-year air-toxics personal-exposure study, October 2009.
Houston Air Toxics Biomarkers of Exposure Study — Research grant ($100K) awarded to Texas A&M University for a year-long study designed to examine the utility of biomarker concentrations as an indication of ambient exposure to compounds of concern as well as correlate biomarker levels observed to levels measured in the ambient air, December 2009.
Air Pollutant Concentrations Near Texas Roadways — Research grant ($250K) awarded to the University of Texas Department of Chemical Engineering to measure both gas- and particle-phase contaminants from four sites, with each site representing a different traffic scenario, August 2007.
TCEQ toxicologists often participate in national workshops and serve on expert panels and are often invited to present at well-respected conferences and events.
Several TCEQ toxicologists have received prestigious awards and honors throughout their careers.
TCEQ toxicologists have written and cowritten research articles on a wide variety of toxicological subjects in a number of scientific journals. Complete list of research articles written and cowritten by TCEQ toxicologists.
