“Sekuyi-dj vu futhi.” Ku-Horticulture and Home Pest News, mhla zi-3 kuMbasa 1991, sifake isihloko mayelana nezingozi zokusebenzisa “itshoko yezinambuzane” engekho emthethweni ukulawula izinambuzane zasekhaya. Inkinga isekhona, njengoba kuboniswe kulokhu okushiwo yi-California Environmental Protection Agency (eguquliwe).

ISEXWAYISO ESIKHISHWE NGOMBUYISI WEZILWANE “WE-CHALK”: INGOZI EZINGANENI

UMnyango Wezokulawulwa Kwezibulala-zinambuzane waseCalifornia kanye Nezinsizakalo Zezempilo namuhla uxwayise abathengi ngokusebenzisa ishoki yokubulala izinambuzane engekho emthethweni. “Le mikhiqizo iyingozi ngendlela ekhohlisayo. Izingane zingayithatha kalula njengeshoki evamile yasekhaya,” kusho isikhulu sezempilo sikahulumeni uJames Stratton, MD, MPH, “Abathengi kufanele bayigweme.” “Kusobala ukuthi ukwenza isibulala-zinambuzane sibukeke njengethoyizi kuyingozi – futhi akuvumelekile,” kusho iPhini likaMqondisi oyiNhloko ye-DPR uJean-Mari Peltier.”

Imikhiqizo — ethengiswa ngamagama ahlukahlukene okuhweba okubalwa kuwo i-Pretty Baby Chalk, kanye ne-Miraculous Insecticide Chalk — iyingozi ngezizathu ezimbili. Okokuqala, ingaba futhi iphazanyiswe njenge-common household chalk futhi idliwe yizingane, okubangela izifo eziningana. Okwesibili, imikhiqizo ayibhalisiwe, kanti izithako kanye nokupakishwa akukalawulwa.

I-US Environmental Protection Agency ithathe isinyathelo ngokumelene nomunye wabasabalalisi futhi ikhiphe umyalelo ku-Pretty Baby Co., ePomona, eCalif., wokuba “iyeke ukuthengisa umkhiqizo ongabhalisiwe oyingozi empilweni yomphakathi.” I-Pretty Baby imaketha ngenkuthalo umkhiqizo wayo ongabhalisiwe kubathengi nasezikoleni ku-inthanethi nasezikhangisweni zamaphephandaba.

“Imikhiqizo efana nale ingaba yingozi kakhulu,” kusho uPeltier. “Umenzi angashintsha ifomula kusuka kwelinye ibhetshi aye kwelinye futhi uyayishintsha.” Isibonelo, amasampula amathathu omkhiqizo obhalwe ukuthi “Miraculous Insecticide Chalk” ahlaziywa yi-DPR ngenyanga edlule. Amabili aqukethe i-deltamethrin yezinambuzane; eyesithathu yayiqukethe i-cypermethrin yezinambuzane.

I-Deltamethrin kanye ne-cypermethrin yi-pyrethroids yokwenziwa. Ukuchayeka ngokweqile kungadala imiphumela emibi yezempilo, okuhlanganisa ukuhlanza, ubuhlungu besisu, ukudlikizela, ukuthuthumela, i-coma, kanye nokufa ngenxa yokwehluleka ukuphefumula. Ukusabela okukhulu kokungezwani komzimba nakho kungenzeka.

Amabhokisi anemibala avame ukusetshenziswa kule mikhiqizo atholakale equkethe amazinga aphezulu e-lead kanye nezinye izinsimbi ezisindayo emaphaketheni. Lokhu kungaba yinkinga uma izingane zibeka ibhokisi emilonyeni yazo noma ziphatha amabhokisi bese zidlulisela insalela yensimbi emilonyeni yazo.

Imibiko yezifo ezingavamile ezinganeni ihlotshaniswa nokugwinya noma ukuphatha ishoki. Okubi kakhulu kwenzeka ngo-1994, lapho ingane yaseSan Diego ilaliswa esibhedlela ngemuva kokudla ishoki ebulala izinambuzane.

Abathengi abathenge le mikhiqizo engekho emthethweni akufanele bayisebenzise. Lahla umkhiqizo ezindaweni zokulahla imfucuza eyingozi yasekhaya.
