Management of Toxic and Concern Chemicals

• Toxic Chemical Substances (referred to as "toxicants"): Refers to chemical substances intentionally produced or unintentionally derived during the manufacturing process, as determined by the Ministry of Environment, based on the toxicity classification criteria. The classification is as follows:
  (1) Class 1 Toxic Chemical Substances: Substances that do not easily decompose in the environment or cause pollution to the environment or harm to human health due to bioaccumulation, biomagnification, or biotransformation.
  (2) Class 2 Toxic Chemical Substances: Substances that have carcinogenic, reproductive toxicity, teratogenic, mutagenic, or other chronic effects.
  (3) Class 3 Toxic Chemical Substances: Substances that, upon exposure, immediately endanger human health or biological life.
  (4) Class 4 Toxic Chemical Substances: Substances that have endocrine-disrupting characteristics or pollute the environment, causing harm to human health.
• Concerned Chemical Substances (referred to as "toxicants"): Refers to chemical substances other than toxic chemical substances that, based on their characteristics or issues of concern domestically and internationally, are determined by the Ministry of Environment to pose a risk of environmental pollution or harm to human health, and are announced accordingly.
• According to the "Management of Toxic and Concerned Chemical Substances Act," the announced substances are classified and managed based on the principles of quantity control. The management includes prohibition, restriction, permission, approval, and registration, aiming to enhance management efficiency.
• To strengthen the assessment and preventive measures against the hazards of toxic substances and prevent toxic disasters, in addition to reporting and submitting reduction plans for the release of toxic substances, those using or storing toxic chemical substances must register and obtain approval from the local environmental protection agency before operation.

Information for Chemicals Administration

The use of chemical substances is widespread in daily life, and most of them are safe. However, certain substances, intentionally produced or unintentionally derived during manufacturing processes, can pose environmental hazards or harm human health. Prolonged exposure to these chemicals in the environment may lead to pathological changes in the human body. In order to facilitate teaching and research, laboratories often need to use toxic substances. To prevent potential harm to human health and the environment due to negligence in the management of toxic substances, it is essential to establish a robust management system, implement appropriate education and training, and take necessary measures for handling and protection.
