Bungwe la US Environmental Protection Agency likupereka lingaliro loletsa kugwiritsa ntchito methylene chloride, mankhwala omwe likunena kuti angayambitse zoopsa paumoyo komanso imfa, pofuna kuteteza thanzi la anthu.
Lingaliroli liletsa kugwiritsa ntchito methylene chloride m'malo onse ogwiritsidwa ntchito ndi anthu komanso m'mafakitale ndi m'mabizinesi. Methylene chloride imagwiritsidwa ntchito mu aerosol degreasers, mu utoto ndi zotsukira maburashi, zomatira zamalonda ndi zomatira, komanso popanga mankhwala ena m'mafakitale.
Kuletsa kumeneku kunaperekedwa ngati gawo la Toxic Substances Control Act, yomwe, pakati pa zoletsa zina, imapatsa Environmental Protection Agency mphamvu zokakamiza malipoti, kusunga zolemba ndi kuyezetsa. Mu 2019, Environmental Protection Agency inaletsa wogula m'modzi kugwiritsa ntchito methylene chloride poichotsa pa utoto.
Anthu osachepera 85 afa chifukwa chogwiritsa ntchito mankhwala kuyambira mu 1980, malinga ndi bungwe la US Environmental Protection Agency. Bungwe la EPA linati milandu yambiri imakhudza ogwira ntchito omwe ali ndi mapangano okonza nyumba. Bungweli linati pali milandu "yatsopano" ya anthu omwe akuvutika ndi mavuto aakulu komanso okhalitsa atatha kugwiritsa ntchito methylene chloride. Bungwe la Environmental Protection Agency lapezanso zotsatirapo zoyipa pa thanzi chifukwa chopuma mpweya ndi kukhudzana ndi khungu, kuphatikizapo poizoni wa mitsempha, zotsatira za chiwindi, ndi khansa.
Bungweli linapeza kuti methylene chloride “imayambitsa chiopsezo chachikulu cha kuvulaza thanzi la anthu omwe akugwiritsa ntchito mankhwalawo” chifukwa cha zoopsa zomwe zingachitike kwa ogwira ntchito omwe akhudzidwa mwachindunji kapena mwanjira ina ndi mankhwalawo, ogula omwe amagwiritsa ntchito mankhwalawo, ndi anthu omwe akhudzidwa ndi mankhwalawo.
"Sayansi ya methylene chloride ndi yomveka bwino, ndipo kukhudzana ndi methylene chloride kungayambitse mavuto aakulu pa thanzi komanso imfa," adatero Woyang'anira EPA Michael S. Regan m'nkhani yofalitsa nkhani. Izi ndi zoona kwa mabanja ambiri omwe ataya okondedwa awo chifukwa cha poizoni woopsa," akutero pempholi. "Ndicho chifukwa chake bungwe la Environmental Protection Agency likuchitapo kanthu popereka lingaliro loletsa kugwiritsa ntchito mankhwala ambiriwa ndikugwiritsa ntchito njira zowongolera zolimba m'malo ogwirira ntchito kuti ateteze thanzi la ogwira ntchito ndikuchepetsa kukhudzana ndi mankhwala m'malo ena onse."
Cholinga cha chiletso chomwe chikuperekedwachi ndikuteteza anthu ku zoopsa ndikuchepetsa kufalikira kwa methylene chloride polola kugwiritsa ntchito methylene chloride pokhapokha ngati zinthu zili bwino m'malo ogwirira ntchito, malinga ndi bungwe la Environmental Protection Agency. Kupanga, kukonza ndi kufalitsa methylene chloride kudzatha m'miyezi 15 ikubwerayi. Ngati lingaliro laletsa mankhwalawo, kusanthula kwa EPA kunapeza kuti "zinthu zina zotsika mtengo komanso zogwira mtima zofanana ... nthawi zambiri zimapezeka."
"Kuletsa kumeneku komwe kwaperekedwa kale kukuwonetsa kupita patsogolo kwakukulu komwe tapanga pakukhazikitsa chitetezo chatsopano cha mankhwala ndikuchitapo kanthu mochedwa kuti titeteze bwino thanzi la anthu," adatero Regan.
Kerry Breen ndi mkonzi wa nkhani komanso mtolankhani wa CBS News. Malipoti ake amayang'ana kwambiri zochitika zaposachedwa, nkhani zatsopano komanso kugwiritsa ntchito mankhwala osokoneza bongo.
