CO OZNACZA SŁOWO DIELDRIN
Dieldryna
Dieldryna jest chlorowanym węglowodorem pierwotnie wyprodukowanym w 1948 r. Przez J. Hyman \u0026 Co, Denver, jako insektycyd. Dieldryna jest ściśle związana z aldryną, która reaguje dalej w celu utworzenia dieldryny. Aldryna nie jest toksyczna dla owadów; jest on utleniany w owad, tworząc dieldrynę, która jest związkiem czynnym. Zarówno dieldryna jak i aldryna są nazwane po reakcji Diels-Alder, która jest stosowana do tworzenia aldryny z mieszaniny norbornadienu i heksachlorocyklopentadienu. Pierwotnie rozwinięty w latach 40. XX w. Jako alternatywa dla DDT, dieldryna okazała się wysoce skutecznym środkiem owadobójczym i była szeroko stosowana w latach pięćdziesiątych do wczesnych lat 70. XX wieku. Endryna jest stereoizomerem dieldryny. Jest to jednak bardzo trwały zanieczyszczenie organiczne; to nie łatwo zerwać. Ponadto wykazuje tendencję do biomagnify w miarę przenoszenia łańcucha pokarmowego. Długotrwała ekspozycja okazała się toksyczna dla bardzo szerokiego kręgu zwierząt, w tym ludzi, znacznie większych niż oryginalne cele owadów. Z tego powodu jest ona obecnie zakazana w większości krajów świata. Jest to związane z problemami zdrowotnymi, takimi jak choroba Parkinsona, rak piersi i uszkodzenie układu odpornościowego, rozrodczego i nerwowego.
