Humans can be exposed to organohalogens through dietary intake, inhalation, and dermal contact. The primary route of exposure is through the consumption of contaminated food, particularly fish, meat, and dairy products, which are high in fat where these compounds accumulate. Occupational exposure is also a concern for individuals working in industries that produce or use organohalogens. Additionally, these compounds can be released into the air and water during manufacturing processes, leading to environmental exposure.
