Definition
HCB, or hexachlorobenzene, is a persistent organic pollutant that is formed as a byproduct of various industrial processes. It is highly toxic and can bioaccumulate in the environment.
Dioxins are a group of highly toxic chemicals that are also persistent organic pollutants. They are formed as byproducts of certain industrial activities and can have serious health effects on humans and wildlife.
Furans are another group of toxic chemicals that are similar to dioxins. They are also formed as byproducts of industrial processes and can pose significant risks to human health and the environment.
Bioaccumulation refers to the process where substances, such as HCB, build up in the tissues of organisms over time. This can lead to higher concentrations of toxins in organisms higher up in the food chain.
