kemikalien
Kemikalien are substances with a defined composition that can be elements or compounds. They may occur naturally, such as minerals and atmospheric gases, or be manufactured synthetically for a wide range of applications. In everyday use the term covers simple substances as well as complex mixtures and polymers. The study of kemikalien includes their structure, properties, reactions, and how they interact with living systems and the environment.
Chemically, kemikalien are broadly divided into inorganic and organic groups. Inorganic examples include minerals, metals, salts,
The production and use of kemikalien are central to the chemical industry, which provides substances for manufacturing,
Safety and regulation govern their handling. Labels and safety data sheets provide hazard information, and international
Environmental and health considerations include toxicity, exposure, and pollution. Responsible use emphasizes risk assessment, substitution of
