Health Hazards: Criteria for classifying substances that pose risks to human health, such as carcinogenicity, mutagenicity, reproductive toxicity, and specific target organ toxicity. Environmental Hazards: Criteria for substances that pose risks to the environment, including aquatic toxicity, ozone layer hazards, and persistence. Physical Hazards: Criteria for substances that present physical risks, such as explosiveness, flammability, and oxidizing properties.
These elements are critical for a comprehensive assessment of how chemicals interact with biological systems and ecosystems.
