What are chronic toxicity tests primarily conducted to determine?

Chronic toxicity tests are primarily conducted to determine the long-term effects of exposure to a substance, particularly focusing on potential carcinogenic (cancer-causing) and teratogenic (developmental harm to embryos or fetuses) effects. These tests assess how prolonged exposure to a chemical may impact health over time, including any risks of cancer development or developmental abnormalities that might arise from continued exposure to toxic substances.

The focus on these longer-term health effects sets chronic toxicity tests apart from other types of testing that may investigate immediate reactions or short-term consequences. This specificity is crucial in risk assessment and regulatory processes, helping to establish guidelines and safety measures for the use of chemicals that might pose serious long-term health risks.
