CTEH^® scientists have a broad range of toxicological experiences, including critique and evaluation of proposed regulations relating to chemicals in air, water, or foods; review and evaluation of animal toxicity testing studies; development of Reference Dose values for chemicals and proposal of revisions to existing values based on new toxicological data; critical evaluation of corporate health and safety plans; evaluation and coordination of the results of employee health monitoring and training programs; review and summarization of corporate Material Safety Data Sheets; and, evaluation of scientific literature for strengths and weaknesses for use in human health toxicity evaluation and risk assessment. In addition, CTEH^® toxicologists routinely assess human exposure to chemicals in the environment due to exposure to affected soil, water, or air, and evaluate potential health risks associated with the assessed exposures.
