bifenili policlorurați, estimarea riscului, impact asupra organismelorRezumat
În lucrare sunt prezentate rezultatele studiului privind conținutul de bifenili policlorurați în probele de sol și sedimente prelevate de la stația de transformatoare de putere mare din orașul Ciadâr-Lunga, precum și impactul acestor contaminanți asupra diferitor organisme. Prin analiza cromatografică s-a stabilit prezența bifenililor policlorurați în toate probele analizate, ΣBPC variind de la 143,6 mg/kg până la 1671,3 mg/kg. Bifenilii policlorurați prezintă diverse efecte adverse asupra organismelor testate: de la neobservabile (speciile Eisenia fetida și Helix pomatia) până la letale (speciile: Daphnia magna și Phyllobius urticae).
