Most ofthese studies are conducted to assess the degree to which substances are toxic (poisonous)for humans, animals or the environment, to investigate the mechanism of toxic chemicals, orto develop new or improved tests for specific types of chemically induced effects. We beginby explaining the scientific rationale behind important types of studies. These include:examination of adverse effects that may occur on first exposure to a single dose of asubstance (acute toxicity studies), studies that seek to assess the potential of substances tointeract with genetic material (genotoxicity), tests that aim to identify whether toxicityoccurs after continuous exposure to a substance (r)
