Persistent organic pollutants and their effects on Arctic seabirds
Persistent organic pollutants (POPs) and their degradation and metabolic byproducts have been found in high levels in blood and tissues of several Arctic seabirdand mammal species (Glaucous gull (Larus hyperboreus), Ivory gull (Pagophila eburnea), Great skua (Stercorarius skua), Arctic fox (Alopex lagopus) and Polar bear (Ursus maritimus). The POPs include both old (PCBs, DDTs and CHLs) and new...
متن کاملContamination of an arctic terrestrial food web with marine-derived persistent organic pollutants transported by breeding seabirds.
At Cape Vera, Devon Island (Nunavut, Canada), a colony of northern fulmars (Fulmarus glacialis) concentrates and releases contaminants through their guano to the environment. We determined whether persistent organic pollutants (POPs) from seabirds were transferred to coastal food webs. Snow buntings (Plectrophenax nivalis) were the most contaminated species, with ∑PCB and ∑DDT (mean: 168, 106 n...
متن کاملPersistent organic pollutants: potential health effects?
It is not a point of debate that the Stockholm Convention for the prevention of further accumulation of persistent organic pollutants (POPs) should be ratified and implemented by all countries. However, in their article, Schafer and Kegley present an unbalanced "worst case scenario". Approximately 20% of the food supply of the US is contaminated with POPs at extremely low levels; these levels a...
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...
