Dioxins and dioxin-like compounds
Dioxins and Dioxin-like Compounds
Dioxins and dioxin-like compounds (DLCs) are a group of chemical compounds that are highly toxic environmental pollutants. They are mostly by-products of various industrial processes - notably incineration of chemical and hospital waste, and steel manufacturing.
Pronunciation
- Dioxins: /ˈdaɪ.ɒksɪn/
- Dioxin-like Compounds: /ˈdaɪ.ɒksɪn laɪk ˈkɒmpaʊnd/
Etymology
The term "dioxin" is derived from the chemical structure of the simplest member of the class, which consists of two oxygen atoms (di-) linked together (-oxin).
Related Terms

- Polychlorinated dibenzofurans (PCDFs)
- Certain polychlorinated biphenyls (PCBs)
- Persistent organic pollutants (POPs)
Description
Dioxins and dioxin-like compounds are members of the Persistent Organic Pollutants (POPs) group. They are known for their persistence in the environment and their ability to accumulate in the food chain, leading to significant environmental health risks.
Dioxins are highly toxic and can cause reproductive and developmental problems, damage the immune system, interfere with hormones and also cause cancer.
Exposure and Health Effects
Human exposure to dioxins and dioxin-like compounds can occur through the ingestion of contaminated food, inhalation of contaminated air and dust, and skin contact with contaminated soil or dust.
The health effects of dioxins and dioxin-like compounds are diverse, ranging from skin disorders, such as chloracne, to altered liver function, impairment of the immune system, nervous system, endocrine system and reproductive functions.
Prevention and Control
Prevention and control of dioxin and dioxin-like compound exposure involves reducing or eliminating their production, promoting their safe disposal, and monitoring their presence in the environment and food chain.
