I-EPA ivumela ukusetshenziswa okuqhubekayo kwe-chlorpyrifos, i-malathion ne-diazinon ngazo zonke izikhathi ngokuvikela okusha kulebula.Lesi sinqumo sokugcina sisekelwe embonweni wokugcina wezinto eziphilayo we-Fish and Wildlife Service.Ihhovisi lithole ukuthi izinsongo ezingaba khona ezilwaneni ezisengozini zingancishiswa ngemikhawulo eyengeziwe.

"Lezi zinyathelo azigcini nje ngokuvikela izinhlobo ezisohlwini oluvikelekile, kodwa futhi zinciphisa ukuchayeka okungenzeka kanye nomthelela wemvelo kulezi zindawo lapho kusetshenziswa i-malathion, i-chlorpyrifos ne-diazinon," kusho le nhlangano ekukhululweni kwayo.Ukugunyazwa kwelebula ebuyekeziwe yabanikazi bokubhaliswa komkhiqizo kuzothatha cishe izinyanga eziyi-18.

Abalimi nabanye abasebenzisi basebenzisa la makhemikhali e-organophosphorus ukulawula izinhlobonhlobo zezinambuzane ezitshalweni ezihlukahlukene.I-EPA yavala ukusetshenziswa kwe-chlorpyrifos ezitshalweni zokudla ngoFebhuwari ngenxa yezixhumanisi zokulimala kwengqondo ezinganeni, kodwa isakuvumela ukuthi isetshenziselwe okunye ukusetshenziswa, okuhlanganisa nokulawula omiyane.

Zonke izibulala-zinambuzane zibhekwa njengobuthi obukhulu ezilwaneni ezincelisayo, izinhlanzi kanye nezilwane ezingenamgogodla zasemanzini yi-US Fish and Wildlife Service kanye ne-NOAA Fisheries Division.Njengoba kudingwa umthetho wobumbano, i-EPA yaxoxisana nama-ejensi amabili mayelana nombono webhayoloji.

Ngaphansi kwemikhawulo emisha, i-diazinon akufanele ifuthwe emoyeni, futhi i-chlorpyrifos ayikwazi ukusetshenziswa ezindaweni ezinkulu ukulawula izintuthwane, phakathi kwezinye izinto.

Okunye ukuvikela kuhloswe ngayo ukuvimbela izibulala-zinambuzane ukuthi zingangeni emanzini kanye nokuqinisekisa ukuthi wonke umthwalo wamakhemikhali uyancishiswa.

I-NOAA Fisheries Division yaphawula ukuthi ngaphandle kwemingcele eyengeziwe, amakhemikhali angaba yingozi ezilwaneni nasezindaweni zazo.
