Detailed explanation-1: -POPs (such as dioxins) can build up in animal tissues over time through a process called bioaccumulation. This means that older animals tend to have higher levels of POPs than younger animals.
Detailed explanation-2: -PFAS are highly persistent in the environment and, according to studies conducted by the CDC, several PFAS are present in the blood of virtually everyone in the general population. They also bioaccumulate in people and wildlife.
Detailed explanation-3: -Dioxin is a highly toxic and persistent substance that is the unintentional by-product of medical waste incineration and PVC plastic production. Other sources of dioxin include paper and pulp mills, municipal incinerators, cement kilns that burn chemical waste, and the manufacturing of some chlorinated pesticides.
Detailed explanation-4: -Dioxins are toxic byproducts of industrial incineration, combustion and chemical manufacturing. Dioxins have been linked to an increased risk of breast cancer.
