Low levels of persistent organic pollutants raise concerns for future generations.
Bans and regulation in many countries have reduced the environmental levels of many persistent organic pollutants (POPs). Despite these declines, there is still evidence of exposures in a range associated with adverse health effects. This seeming paradox is a result of the realisation that levels once presumed safe can cause subtle but important health effects. For example, levels of PCBs now s...
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 کاملChapter 8 Persistent Organic Pollutants
The rapid growth in chemical and agrochemical industries during the last century have resulted in the environmental releases of a large number of new chemical compounds into the environment. According to the OECD, the daily use of chemicals includes about 70,000 mainly organic synthetic chemicals, and the number increases continuously (Schwarzenbach et al. 1993). Over the last decades, there ha...
