“Sekuphinde kwaba ngu-dj vu.”Kuyi-Horticulture and Home Pest News, ka-April 3, 1991, sahlanganisa nesihloko esiphathelene nezingozi zokusebenzisa “ushoki wezibulala-zinambuzane” ongekho emthethweni ekulawuleni izinambuzane zasendlini.Inkinga isekhona, njengoba kukhonjisiwe kulokhu kukhishwa kwezindaba kwe-California Environmental Protection Agency (okulungisiwe).

ISEXWAYISO SIKHISHWE NGESITHI “CHALK”:INGOZI EZINGANE

I-California Departments of Pesticide Regulation and Health Services namuhla ixwayise abathengi ngokusebenzisa ushoki wokubulala izinambuzane ongekho emthethweni.“Le mikhiqizo iyingozi ngendlela ekhohlisayo.Izingane zingaziphambanisa kalula njengoshoki ovamile wasendlini,” kusho iSikhulu Sezempilo Sombuso uJames Stratton, MD, MPH, “Abathengi kufanele bazigweme.”"Ngokusobala, ukwenza isibulala-zinambuzane sibukeke njengethoyizi kuyingozi-futhi akukho emthethweni," kusho iPhini Lomqondisi Omkhulu we-DPR uJean-Mari Peltier.

Imikhiqizo - ethengiswa ngamagama ahlukene okuhweba okuhlanganisa i-Pretty Baby Chalk, ne-Miraculous Insecticide Chalk - iyingozi ngenxa yezizathu ezimbili.Okokuqala, bangaba futhi baye baphambanisa njengoshoki ovamile wasendlini futhi badliwe yizingane, okubangela izifo eziningana.Okwesibili, imikhiqizo ayibhalisiwe, futhi izithako kanye nokupakishwa akulawulwa.

I-US Environmental Protection Agency ithathele izinyathelo omunye wabasabalalisi futhi yakhipha umyalo kuPretty Baby Co., ePomona, Calif., ukuthi "bayeke ukuthengisa umkhiqizo ongabhalisiwe oyingozi empilweni yomphakathi."I-Pretty Baby imaketha ngenkuthalo umkhiqizo wayo ongabhalisiwe kubathengi nasezikoleni ku-inthanethi nasezikhangisweni zamaphephandaba.

“Imikhiqizo efana nalena ingaba yingozi kakhulu,” kusho uPeltier."Umkhiqizi angakwazi - futhi uyakwenza-ukushintsha ifomula isuka kuqeqebana elilodwa iye kwelandelayo."Isibonelo, amasampula amathathu omkhiqizo obhalwe ukuthi “I-Miraculous Insecticide Chalk” ahlaziywa yi-DPR ngenyanga edlule.Ezimbili zaziqukethe isibulala-zinambuzane i-deltamethrin;eyesithathu yayinesibulala-zinambuzane i-cypermethrin.

I-Deltamethrin ne-cypermethrin yi-synthetic pyrethroids.Ukuchayeka ngokweqile kungadala imiphumela emibi kakhulu yezempilo, ehlanganisa ukuhlanza, izinhlungu zesisu, ukudlikizela, ukuvevezela, ukuquleka, nokufa ngenxa yokwehluleka ukuphefumula.Ukungezwani okukhulu komzimba nakho kungenzeka.

Amabhokisi anemibala ngokuvamile asetshenziselwa le mikhiqizo atholakale equkethe amazinga aphezulu omthofu nezinye izinsimbi ezisindayo ephaketheni.Lokhu kungaba yinkinga uma izingane zibeka ibhokisi emilonyeni yazo noma zibambe amabhokisi bese zidlulisela izinsalela zensimbi emilonyeni yazo.

Imibiko yezifo ezingazodwa ezinganeni iye yaxhunyaniswa nokuwudla noma ukuphatha ushoki.Okubi kakhulu kwenzeka ngo-1994, lapho ingane yaseSan Diego ilaliswa esibhedlela ngemva kokudla ushoki wokubulala izinambuzane.

Abathengi abathenge le mikhiqizo engekho emthethweni akufanele bayisebenzise.Lahla umkhiqizo endaweni yendawo yemfucuza eyingozi.
