YAMBIRO YAPUTSWA PAMUSORO PEMUDZIYO WE "CHOK": NGOZI KUVANA

Dhipatimendi reCalifornia reMishonga Yezvipembenene neHutano nhasi rayambira vatengi kuti vasashandise choko yezvipembenene zvisiri pamutemo. "Zvigadzirwa izvi zvine njodzi zvikuru. Vana vanogona kuzvifungidzira sechoko yemumba," akadaro State Health Officer James Stratton, MD, MPH, "Vatengi vanofanira kuzvidzivisa." "Zviri pachena kuti, kuita kuti mushonga wezvipembenene utaridzike sechitoyi kune njodzi - pamwe nekusatenderwa," akadaro DPR Chief Deputy Director Jean-Mari Peltier.

Zvigadzirwa izvi — zvinotengeswa nemazita akasiyana-siyana ekutengeserana anosanganisira Pretty Baby Chalk, uye Miraculous Insecticide Chalk — zvine njodzi nekuda kwezvikonzero zviviri. Chekutanga, zvinogona kunge zvakatorwa sechoko yemumba uye zvakadyiwa nevana, zvichikonzera zvirwere zvakasiyana-siyana. Chechipiri, zvigadzirwa izvi hazvina kunyoreswa, uye zvinoshandiswa uye kurongedza hazvina kudzorwa.

Sangano reUS Environmental Protection Agency rakatora matanho kune mumwe wevanopa zvinhu izvi uye rakapa murairo kuPretty Baby Co., iri muPomona, Calif., wekuti "irege kutengesa chigadzirwa chisina kunyoreswa chinokuvadza hutano hwevanhu." Pretty Baby iri kushambadzira chigadzirwa chayo chisina kunyoreswa kuvatengi nezvikoro paInternet uye mukushambadzira mumapepanhau.

“Zvigadzirwa zvakaita seizvi zvinogona kuva nengozi zvikuru,” akadaro Peltier. “Mugadziri anogona — uye anoita — kuchinja fomura kubva pane imwe batch kuenda kune inotevera.” Semuenzaniso, sampuro nhatu dzechigadzirwa chakanyorwa kuti “Miraculous Insecticide Chalk” dzakaongororwa neDPR mwedzi wapera. Mbiri dzacho dzaiva ne deltamethrin yezvipembenene; yechitatu yaiva ne cypermethrin yezvipembenene.

Deltamethrin ne cypermethrin mishonga inogadzirwa inonzi pyrethroids. Kugara uchinyanya kushandisa mishonga iyi kunogona kukonzera matambudziko makuru pahutano, kusanganisira kurutsa, kurwadziwa mudumbu, kugwinha, kudedera, kufinha, uye kufa nekuda kwekutadza kufema. Zvinogonawo kukonzera allergy.

Mabhokisi ane mavara anowanzo shandiswa pakugadzira zvinhu izvi akawanikwa aine simbi dzakawanda dzesimbi dzinorema mupakeji. Izvi zvinogona kuva dambudziko kana vana vakaisa bhokisi mumuromo mavo kana kubata mabhokisi acho voendesa zvasara zvesimbi kumuromo mavo.

Mishumo yezvirwere zvevana zvakapararira yakabatana nekumedzwa kana kubata choko. Chakakomba zvikuru chakaitika muna 1994, apo mwana wekuSan Diego akaiswa muchipatara mushure mekudya choko inouraya zvipembenene.

Vatengi vakatenga zvinhu izvi zvisiri pamutemo havafanirwe kuzvishandisa. Rasa chigadzirwa ichi munzvimbo dzinorasirwa marara ane njodzi mudzimba dzemunharaunda.
