“Ni dj vu byongeye kuba.” Mu kinyamakuru Horticulture and Home Pest News, ku ya 3 Mata 1991, twashyizemo inkuru ivuga ku ngaruka zo gukoresha “ingwa y’udukoko” itemewe mu kurwanya udukoko two mu ngo. Ikibazo kiracyari hanze, nk’uko bigaragara muri iyi nkuru y’ikigo gishinzwe kurengera ibidukikije cya California (yahinduwe).

UMUBURO WATANZWE KU BICURASI BYA “ICYAMA”: AKAGA KU BANA

Ishami rishinzwe kugenzura imiti yica udukoko muri California n’ibikorwa by’ubuzima uyu munsi ryaburiye abaguzi kwirinda gukoresha ingwa itemewe n’amategeko. “Ibi bicuruzwa ni bibi cyane. Abana bashobora kubyitiranya n’ingwa isanzwe yo mu rugo,” uyu ni James Stratton, MD, MPH, Umuyobozi Mukuru w’Ubuzima muri Leta, “Abaguzi bagomba kubyirinda.” “Birumvikana ko gutuma umuti wica udukoko usa n’igikinisho ari bibi – ndetse n’amategeko,” uyu ni Jean-Mari Peltier, Umuyobozi Mukuru Wungirije wa DPR.”

Ibicuruzwa — bigurishwa mu mazina atandukanye y’ubucuruzi harimo Pretty Baby Chalk, na Miraculous Insecticide Chalk — ni bibi kubera impamvu ebyiri. Iya mbere, bishobora kuba kandi byaratekerejweho nk'ingwa isanzwe yo mu rugo kandi bikaba byaribwa n'abana, bigatera indwara nyinshi. Iya kabiri, ibicuruzwa ntibirandikishwa, kandi ibikoresho n'ibipfunyika nta mategeko abigenga.

Ikigo gishinzwe kurengera ibidukikije muri Amerika cyafatiye ingamba umwe mu bacuruza ibi bicuruzwa ndetse gitanga itegeko kuri Pretty Baby Co., i Pomona, muri Calif., ryo “kureka kugurisha ibicuruzwa bitaranditswe byangiza ubuzima rusange.” Pretty Baby icuruza ibicuruzwa byayo bitaranditswe ku bakiriya n’amashuri kuri interineti no mu binyamakuru.

“Ibicuruzwa nk'ibi bishobora guteza akaga gakomeye,” Peltier yagize ati. “Uwabikoze ashobora — kandi arabikora — guhindura formula kuva ku itsinda rimwe ajya ku rindi.” Urugero, ingero eshatu z'ibicuruzwa byanditseho “Ishaki y'insecticide itekse” zasesenguwe na DPR mu kwezi gushize. Ebyiri byarimo deltamethrin y'insecticide; iya gatatu yarimo cypermethrin y'insecticide.

Deltamethrin na cypermethrin ni imiti ikomoka kuri pyrethroids. Kuyikoresha cyane bishobora kugira ingaruka zikomeye ku buzima, harimo kuruka, kubabara mu nda, kuribwa mu nda, guhinda umushyitsi, kugwa muri koma no gupfa bitewe no kunanirwa guhumeka. Hari n'ingaruka zikomeye ku barwayi ba ubwivumbure.

Udusanduku tw'amabara menshi dukoreshwa kuri ibi bicuruzwa byagaragaye ko turimo urugero rwinshi rw'ubutare n'ibindi byuma biremereye mu ipaki. Ibi bishobora kuba ikibazo iyo abana bashyize agasanduku mu kanwa kabo cyangwa bagafata udusanduku maze bagashyira ibisigazwa by'icyuma mu kanwa kabo.

Raporo z’indwara zandura ku bana zagaragaye ko ziterwa no kurya cyangwa gufata ingwa. Indwara ikomeye cyane yabaye mu 1994, ubwo umwana wo muri San Diego yajyanwaga mu bitaro nyuma yo kurya ingwa yica udukoko.

Abaguzi baguze ibi bicuruzwa bitemewe n'amategeko ntibagomba kubikoresha. Shyira ibyo bicuruzwa ahantu hateje akaga mu ngo zabo.
