Environmental Toxicology

PBS&J’s environmental toxicology laboratory has been in continuous operation since 1978, and is located in state-of-the-art facilities in Houston, Texas. The laboratory is accredited by the State of Florida under the National Environmental Laboratory Accreditation Program (NELAP). PBS&J provides a wide range of testing services for both marine and freshwater environments, including effluent biomonitoring using acute and short-term chronic whole effluent toxicity (WET) tests, toxicity reduction evaluations (TRE), sediment toxicity characterizations, and product toxicity testing for evaluation of chemicals and product mixtures used in the environment.

As part of our commitment to client service, PBS&J offers door-to-door sample handling and transport (including sample collection, where needed), custom reporting, and computer-based information management tools for tracking of permit requirements to assure compliance with testing schedules. We maintain an extensive culture facility for the production of test organisms routinely used in the laboratory. Our experienced toxicologists, chemists, and environmental engineers investigate and identify the causes and sources of toxicity and provide cost-effective solutions for compliance with permit requirements. Programs support material testing for open-water or confined disposal sites conducted in accordance with USEPA, USACOE, or regional guidelines.
