I-EPA ivumela ukusetyenziswa okuqhubekayo kwe-chlorpyrifos, i-malathion kunye ne-diazinon kuzo zonke izihlandlo kunye nokukhusela okutsha kwilebula.Esi sigqibo sokugqibela sisekelwe kuluvo lokugqibela lwebhayoloji yeNkonzo yeeNtlanzi kunye neZilwanyana zasendle.Eli ziko lifumanise ukuba izoyikiso ezinokuthi zibe kho kwizilwanyana ezisengozini zinokuthotywa ngothintelo olongezelelweyo.

"La manyathelo awakhuseli kuphela iintlobo ezikhuselweyo ezidweliswe, kodwa zinciphisa ukuvezwa okunokwenzeka kunye neempembelelo zendalo kule mimandla xa kusetyenziswa i-malathion, i-chlorpyrifos kunye ne-diazinon," i-arhente yatsho ekukhululweni.Ukuvunywa kweleyibhile ehlaziyiweyo kubanini bemveliso yobhaliso kuya kuthatha malunga neenyanga ezili-18.

Abalimi kunye nabanye abasebenzisi basebenzisa le michiza ye-organophosphorus ukulawula iintlobo ezininzi zezinambuzane kwizityalo ezahlukeneyo.I-EPA yavala ukusetyenziswa kwe-chlorpyrifos kwizityalo zokutya ngoFebruwari ngenxa yokudibanisa nokulimala kwengqondo ebantwaneni, kodwa isavumela ukuba isetyenziswe kwezinye izinto, kubandakanywa nokulawulwa kweengcongconi.

Zonke izitshabalalisi zithathwa njengetyhefu kakhulu kwizilwanyana ezanyisayo, iintlanzi kunye nezilwanyana ezingenamqolo yi-US Fish and Wildlife Service kunye ne-NOAA Fisheries Division.Njengoko kufunwa ngumthetho wobumbano, i-EPA yabonisana neearhente ezimbini malunga noluvo lwebhayoloji.

Ngaphantsi kwezithintelo ezintsha, i-diazinon akufanele itshizwe emoyeni, kwaye i-chlorpyrifos ayinakusetyenziswa kwiindawo ezinkulu ukulawula iimbovane, phakathi kwezinye izinto.

Olunye ukhuselo lujolise ekuthinteleni amayeza okubulala izitshabalalisi ekungeneni emanzini nasekuqinisekiseni ukuba wonke umthwalo weekhemikhali uyancitshiswa.

I-NOAA Fisheries Division yaqaphela ukuba ngaphandle kwemiqathango eyongezelelweyo, iikhemikhali ziza kubangela ingozi kwiintlobo kunye neendawo zazo zokuhlala.
