What foods have persistent organic pollutants?
The dietary exposure of OCPs is mainly from contaminated fatty foods including foods of animal origin such as eggs, dairy product and meat and foods of plant origin such as rice, fruit, vegetables and vegetable oil.
What are persistent environmental pollutants?
Persistent organic pollutants (POPs) are toxic chemicals that adversely affect human health and the environment around the world. They persist for long periods of time in the environment and can accumulate and pass from one species to the next through the food chain.
Where are persistent organic pollutants stored?
Humans are exposed to POPs through external exposure sources such as POPs-contaminated food. However, once POPs enter the body, they are primarily stored in adipose tissue and slowly released into the circulation to be eliminated over several years (12).
What causes persistent organic pollutants?
Persistent Organic Pollutants (POPs) are toxic substances composed of organic (carbon-based) chemical compounds and mixtures. They include industrial chemicals like PCBs and pesticides like DDT. They are primarily products and by-products from industrial processes, chemical manufacturing and resulting wastes.
How can we prevent persistent organic pollutants?
Purchase organic foods whenever possible. If you do eat non-organic meat and fish, avoid the fat and skin, as persistent organic pollutants — chemical substances that are harmful, persist in the environment for long periods of time, and biomagnify as they move up the food chain — concentrate there.
What are some examples of organic pollutants?
Organic pollutants includes phenols, chlorinated phenols, endocrine disrupting chemicals, azo dyes, polyaromatic hydrocarbons, polychlorinated biphenyls, pesticides, etc., whereas inorganic pollutants includes a variety of toxic heavy metals such as cadmium (Cd), chromium (Cr), arsenic (As), lead (Pb), mercury (Hg).
How do persistent organic pollutants affect humans?
Persistent organic pollutants cause a variety of adverse health effects, including cancer, immune system suppression, decrements in cognitive and neurobehavioral function, disruption of sex steroid and thyroid function, and at least some of them increase the risk of chronic diseases, such as hypertension.
What is a persistent organic pollutant examples?
Examples of persistent organic pollutants include:
What are the organic water pollutants?
3 Organic Contaminants. Organic contaminants including dye, humic substances, phenolic compounds, petroleum, surfactants, pesticides, and pharmaceuticals are important pollutants in wastewaters. The presence of organic contaminants in water may produce toxic chemicals during disinfection.
