What Is Toxicology?
Toxicology is the study of the adverse effects of chemicals on
living organisms. A toxicologist is trained to examine the nature
of those effects and assess the probability of their
occurrence.
Toxicology is used to help the TCEQ make scientifically sound
decisions when developing environmental regulations and policy.
TCEQ toxicologists help by identifying chemical hazards, evaluating
potential exposures, and assessing risks.
What Do TCEQ Toxicologists Do?
TCEQ toxicologists provide toxicological support for a broad
range of agency activities. They assist with stakeholder meetings
and drafting rules, as well as making technical recommendations
regarding agency permitting, monitoring, and enforcement.
For example, TCEQ toxicologists:
- Conduct the toxicological evaluations of
air permit applications;
- Develop
Effects Screening Levels;
- Evaluate environmental data collected from the air, water, and
soil;
- Contribute toxicological expertise to agency enforcement and
emergency-response activities;
- Coordinate all agency activities that assess risks to human
health;
- Notify private drinking-water well owners of potential
groundwater contamination as required by new legislation in Texas
Water Code 26.408;
- Stay abreast of environmental-health issues and initiatives
emerging nationally; and
- Review Baseline Risk Assessments and various other
remediation-related documents submitted under the Texas
Risk Reduction Program and the Risk
Reduction Rules for state and federal Superfund sites.
In all areas of responsibility, the section strives to ensure
consistency of reviews across the agency.
