Dioxins: source, origin and toxicity assessment
Dioxins: source, origin and toxicity assessment is a scholarly work, published in 2018 in ''Biodiversity International Journal''. The main subjects of the publication include genotoxicity, persistent organic pollutant, toxicity, environmental science, bioremediation, and environmental chemistry. Persistent, bioaccumulative and toxic chemicals (PBTs) are substances that can build up to levels that can be harmful to human and ecological health.These contaminants may travel long distances in the atmosphere and can move readily from land to air and water.The accumulation of such chemicals in organisms from the surrounding environment through absorption, ingestion and inhalation may cause severe health issues.Dioxin is formed as an unintentional by-product of many industrial processes involving chlorine such as waste incineration, chemical and pesticide manufacturing, treatment of hazardous material and pulp and paper bleaching.The potential for health risks due to the cancer-promoting, immunomodulating and teratogenic activities of dioxins in rodents has raised concerns over their presence in the human food chain.There is an urgent need of taking attention on sources of emission of dioxin and its mitigation measures.In this chapter, the sources, its origin and toxicity assessment of dioxin has been presented along with 3 case studies.
