Persistent organic pollutants in food supplies.
Persistent organic pollutants (POPs) in various food supplies have important health impacts, but are not as devastating as malnutrition and, perhaps, obesity. POPs should be controlled and the Stockholm Convention is having an accelerating effect on the global decline of POP manufacture and use. Reservoirs from previous misuses are much larger than current manufacture and efforts should be dire...
متن کاملPersistent organic pollutants in food: public health implications.
Persistent organic pollutants are a heterogeneous group of chemicals sharing a number a common properties, including long term persistence and diffusion in the environment, and bioaccumulation through the food chain. Animal experiments and epidemiological studies suggest that the most sensitive adverse effects, such as disturbances on metabolism, development, and reproductive system, may occur ...
متن کاملPersistent Organic Pollutants ("POPs")
Strictly speaking, all toxins entering the environment can be regarded as environmental poisons. Certain pollutants can, acting over long periods, harm living organisms even in low concentrations. This means that pollutants that are stable and thus persistent have a great ability to act as environmental poisons. Their stability means not only that their effects are long-lasting, but also that t...
متن کاملSerum Persistent Organic Pollutants
Persistent organic pollutants (POPs) are manmade organic chemicals that remain in the environment for years or decades. POPs are of special concern because they often remain toxic for decades or longer after release to the environment. The more persistent a toxic chemical is, the greater the probability for human exposure over time. Because they circulate globally long after being released into...
متن کاملFood web-specific biomagnification of persistent organic pollutants.
Substances that accumulate to hazardous levels in living organisms pose environmental and human-health risks, which governments seek to reduce or eliminate. Regulatory authorities identify bioaccumulative substances as hydrophobic, fat-soluble chemicals having high octanol-water partition coefficients (K(OW))(>/=100,000). Here we show that poorly metabolizable, moderately hydrophobic substances...
