I-United States Environmental Protection Agency (i-EPA) ishicilele ukuhlaziywa kwayo kokuqala kwe imiphumela yezibulala-zinambuzane ezintathu ezivamile—I-Clorpyrifos, i-diazinon, ne-malathion - ezinhlotsheni zezilwane ezisengozini nezisongelwa kuzwelonke ezinendawo yazo zisesimweni esibucayi.
Iqiniso ukuthi izibulala-zinambuzane ziyesabeka kubo. Ngokusho kombiko, i-malathion ne-chlorpyrifos kuyalimaza amaphesenti angama-97 asabekayo ezilwaneni nezitshalo eziyi-1.782 ezivikelwe ngaphansi koMthetho Wezinhlobo Ezisengozini Yokushabalala. IDiazinon yehla lelo phesenti laya kumaphesenti angama-79.
IMalathion evame ukusetshenziselwa izithelo, imifino nezitshalo zezinambuzane, kanye nokuqeda imikhaza ezifuyweni. AmaChlorpyrifos asetshenziselwa ukubulala umuhlwa, omiyane nezibungu. IDiazinon yenzelwe amaphela nezintuthwane.
Izinhlobo ezintathu zamakhemikhali kungenzeka ithinte kabi lezo zinhlobo, i-EPA ithole futhi ithi uLori Ann Burd, umqondisi wezempilo kwezemvelo eCentre for Biological Diversity:
Ngokokuqala ngqaEkugcineni, sinemininingwane ekhombisa ukuthi iyinhlekelele kanjani le mibulala-zinambuzane yezinhlobo ezisengozini yokuqothulwa, kusukela ezinyonini kuya kumasele nakwezinhlanzi kuya ezitshalweni. Lezo zibulala-zinambuzane eziyingozi zisetshenziswe ngaphandle kokuhlolwa okufanele amashumi eminyaka futhi manje yisikhathi sokuthatha lolu lwazi olusha futhi senze izindlela ezinengqondo zokuvikela izitshalo, izilwane nabantu kulawo makhemikhali.
I-EPA ivumele izinkampani zamakhemikhali bhalisa ngaphezu kwe-16.000 yezibulala-zinambuzane ngaphandle kokubheka kahle imithelela yayo. Lokhu kufanele kume. Lokho kuhlolwa kuyisinyathelo esikhulu sokuya phambili se-EPA. Manje njengoba sesibazi ubukhulu bengcuphe ebangwa yilezi zibulala-zinambuzane, kusobala ukuthi kudingeka sithathe izinyathelo. I-EPA kumele iqhubekele phambili nokuhlola ezinye izibulala-zinambuzane eziyingozi futhi isebenzise ngokushesha imizamo yokuvimbela ukuqothulwa kwezilwane zasendle eziyivelakancane nezingafani nalezi zibulala-zinambuzane.
Kukhona umbhalo etholakala kusuka kulesi sixhumanisi.
