Regulation of toxic materials is crucial to protect public health and the environment. Governments worldwide have established various laws and guidelines to control the use, storage, and disposal of hazardous substances. Agencies such as the Environmental Protection Agency (EPA) in the United States or the European Chemicals Agency (ECHA) in Europe set limits on exposure and conduct risk assessments to ensure safety. Regulations also require manufacturers to perform toxicity testing and disclose potential risks associated with their products.
