Dioxin refers to a group of chemically-related compounds that are highly toxic and can cause serious health issues. These compounds are often byproducts of industrial processes, such as the production of herbicides and the burning of waste. Dioxins can accumulate in the food chain, particularly in fatty tissues of animals, leading to increased exposure for humans who consume contaminated food. Exposure to dioxins can result in various health problems, including immune system damage, reproductive issues, and an increased risk of certain cancers. The most well-known dioxin is TCDD, which is often associated with the herbicide Agent Orange used during the Vietnam War. Efforts to reduce dioxin emissions and contamination are ongoing in many countries.
