Abstract

Postojane organske onečišćujuće tvari (POPs) su organski spojevi koji su otporni na fotolitičku, biološku i kemijsku razgradnju te se akumuliraju u živim organizmima i lako se prenose na velike udaljenosti. POPs obuhvaća veliki broj spojeva, a mogu se razvrstati u četiri velike skupine. To su pesticidi, dioksini i furani, poliklorirani bifenili (PCB-i) i policiklički aromatski ugljikovodici (PAH). Toksični su i imaju negativan učinak na okoliš dugi niz godina. Prepoznajući opasnost za ljude i okoliš, proizvodnja POPs-a počela se ograničavati, a sve je na kraju potvrđeno Stochlomskom konvencijom potpisanom 22. svibnja 2001. godine.

Abstract (english)

Persistent organic pollutants (POPs) are organic chemical substances that are resistant to environmental degradation through chemical, biological, and photolytic processes. There are four groups of POPs: pesticides, dioxins and furans, polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAH). Once introduced into the environment, POPs are persistent, retain their toxicity and degrade after decades. Recognizing the dangers of POPs, countries began limiting their production. These efforts culminated in the Stockholm Convention of 22 May 2001.
