lolembedwa ndi Donald Lewis, Dipatimenti ya Zachilengedwe

“Ndi dj vu kachiwiri.” Mu Horticulture and Home Pest News, pa Epulo 3, 1991, tinaphatikizapo nkhani yokhudza kuopsa kogwiritsa ntchito “choko chophera tizilombo” chosaloledwa poletsa tizilombo m'nyumba. Vutoli likadalipobe, monga momwe zasonyezedwera mu nkhani ya California Environmental Protection Agency (yosinthidwa).

CHENJEZO LOPEREKEDWA PA MANKHWALA OPHERA POIPA “CHOKO”: NGOZI KWA ANA

Dipatimenti Yoona za Mankhwala Ophera Tizilombo ku California lero yachenjeza ogula kuti asagwiritse ntchito choko chosaloledwa cha mankhwala ophera tizilombo. "Zogulitsazi ndi zoopsa kwambiri. Ana angaganize kuti ndi choko wamba wapakhomo," adatero Mkulu wa Zaumoyo wa Boma James Stratton, MD, MPH, "Ogula ayenera kuzipewa." "Mwachionekere, kupangitsa mankhwala ophera tizilombo kuoneka ngati chidole n'koopsa - komanso kosaloledwa," adatero Wachiwiri kwa Mtsogoleri wa DPR Jean-Mari Peltier."

Zinthuzi — zomwe zimagulitsidwa m'maina osiyanasiyana ogulitsa kuphatikizapo Pretty Baby Chalk, ndi Miraculous Insecticide Chalk — ndi zoopsa pazifukwa ziwiri. Choyamba, zitha kusokonezedwa ndi choko wamba wapakhomo ndipo zimadyedwa ndi ana, zomwe zimayambitsa matenda angapo. Chachiwiri, zinthuzi sizinalembetsedwe, ndipo zosakaniza ndi ma CD ake sizololedwa.

Bungwe la US Environmental Protection Agency lachitapo kanthu motsutsana ndi m'modzi mwa ogulitsa ndipo lapereka lamulo ku Pretty Baby Co., ku Pomona, Calif., kuti "asiye kugulitsa chinthu chosalembetsedwa chomwe chili chovulaza thanzi la anthu." Pretty Baby imagulitsa mwachangu chinthu chake chosalembetsedwa kwa ogula ndi masukulu pa intaneti komanso m'manyuzipepala.

“Zinthu ngati izi zitha kukhala zoopsa kwambiri,” anatero Peltier. “Wopanga akhoza — ndipo amachitadi — kusintha njira yopangira mankhwala kuchokera ku gulu limodzi kupita ku lina.” Mwachitsanzo, zitsanzo zitatu za mankhwala olembedwa kuti “Miraculous Insecticide Chalk” zinafufuzidwa ndi DPR mwezi watha. Ziwiri zinali ndi mankhwala ophera tizilombo otchedwa deltamethrin; chachitatu chinali ndi mankhwala ophera tizilombo otchedwa cypermethrin.

Deltamethrin ndi cypermethrin ndi mankhwala opangidwa ndi pyrethroids. Kumwa mowa mopitirira muyeso kungayambitse mavuto aakulu pa thanzi, kuphatikizapo kusanza, kupweteka m'mimba, kugwedezeka, kunjenjemera, komanso kufa chifukwa cha kulephera kupuma. Matenda oopsa a ziwengo amathanso kuchitika.

Mabokosi okongola omwe amagwiritsidwa ntchito popanga zinthuzi apezeka kuti ali ndi lead wambiri ndi zitsulo zina zolemera m'mabokosi. Izi zitha kukhala vuto ngati ana ayika bokosi mkamwa mwawo kapena kugwira mabokosiwo ndikusamutsa zotsalira zachitsulozo mkamwa mwawo.

Malipoti a matenda omwe ana amadwala okhawokha akhala akugwirizana ndi kumwa kapena kugwira choko. Choopsa kwambiri chinachitika mu 1994, pamene mwana wa ku San Diego anagonekedwa m'chipatala atadya choko chopha tizilombo.

Ogula omwe agula zinthu zosaloledwazi sayenera kuzigwiritsa ntchito. Tayani zinthuzo pamalo otayira zinyalala zoopsa zapakhomo.
