Toxicology is the scientific study of adverse effects that may result from exposure to chemical, biological, or radiological agents that may be present in consumer and industrial products, in the workplace, or in the environment. Toxicology involves characterizing and quantifying the association from exposure to a substance and the magnitude of effects on human health and/or the environment. The need for scientifically robust assessments of toxicological information arises in numerous contexts relevant to our clients.
