Mu malamulo omwe adaperekedwa omwe adasindikizidwa pa Meyi 3, bungwe la US Environmental Protection Agency likupereka lingaliro loletsa kugwiritsa ntchito dichloromethane, yomwe imadziwikanso kuti dichloromethane, chosungunulira chofala komanso chothandizira kukonza. Imagwiritsidwa ntchito m'njira zosiyanasiyana zogulira ndi zamalonda, kuphatikizapo zomatira ndi zotsekera, zinthu zamagalimoto, ndi zochotsa utoto ndi zokutira. Mankhwalawa amapangidwa mochuluka - pakati pa £100 miliyoni ndi £500 miliyoni kuyambira 2016 mpaka 2019, malinga ndi Chemical Data Report (CDR) - kotero chiletsochi, ngati chitavomerezedwa, chingakhudze kwambiri mafakitale ambiri.
Cholinga cha EPA chikukhudza "chiwopsezo chosafunikira pa thanzi la anthu chomwe dichloromethane imabweretsa malinga ndi momwe igwiritsidwira ntchito, monga momwe zalembedwera mu matanthauzidwe a chiopsezo cha EPA pansi pa Toxic Substances Control Act (TSCA)". Kuwunika chiopsezo cha TSCA ndikugwiritsa ntchito zofunikira mpaka pamlingo wofunikira kuti zitsimikizire kuti mankhwalawo sakubweretsanso chiopsezo chosafunikira.
Kuphatikiza apo, lamulo lomwe laperekedwa ndi EPA likufuna Ndondomeko Yoteteza Malo Ogwirira Ntchito ya Chemical (WCPP), yomwe ikuphatikizapo zofunikira pakutsata malire a kukhudzidwa ndi mpweya komanso kuyang'anira kukhudzidwa ndi kugwiritsa ntchito methylene chloride mosalekeza. Idzakhazikitsanso zofunikira zosungira zolemba ndi zidziwitso zamtsogolo pazifukwa zingapo zogwiritsira ntchito ndikupereka zochotsera zina za nthawi yogwiritsira ntchito zomwe zingayambitse kuvulaza kwakukulu chitetezo cha dziko ndi zomangamanga zofunika.
Makampani omwe amapanga, kutumiza kunja, kukonza, kugawa malonda, kugwiritsa ntchito kapena kutaya methylene chloride kapena zinthu zomwe zili ndi methylene chloride akhoza kukhudzidwa ndi lamulo lomwe likuperekedwali. Lamulo lomwe likuperekedwali likutchula mitundu yoposa 40 ya mafakitale omwe angakhudzidwe ndi lamuloli, kuphatikizapo: kugulitsa mankhwala ambiri, malo osungira mafuta ndi malo osungira mafuta, kupanga mankhwala oyambira achilengedwe ndi osapangidwa, kutaya zinyalala zoopsa, kubwezeretsanso zinthu, opanga utoto ndi utoto; makontrakitala a mapaipi ndi mpweya wozizira; makontrakitala opaka utoto ndi mapepala ophimba mapepala; masitolo ogulitsa zida zamagalimoto ndi zowonjezera; kupanga zida zamagetsi ndi zigawo zake; kupanga zida zosungunulira; ogulitsa magalimoto atsopano ndi ogwiritsidwa ntchito; ntchito zotsukira ndi kuchapa zovala; kupanga zidole, zoseweretsa ndi masewera.
Lamulo lomwe likuperekedwali likunena kuti "Pafupifupi 35 peresenti ya kupanga methylene chloride pachaka imagwiritsidwa ntchito pazifukwa zamankhwala zomwe sizili pansi pa TSCA ndipo sizili pansi pa lamuloli." zomwe sizikuphatikizidwa mu tanthauzo la "mankhwala" m'magawo (B)(ii) mpaka (vi). Zopanda izi "zikuphatikizapo ... chakudya chilichonse, chowonjezera pazakudya, mankhwala, zodzoladzola, kapena chipangizo, monga momwe zafotokozedwera mu Gawo 201 la Federal Food, Drug, and Cosmetic Act, ikapangidwa, kukonzedwa, kapena kugawidwa m'mabizinesi kuti igwiritsidwe ntchito ngati mankhwala. , zodzoladzola kapena zipangizo…"
Kwa mafakitale omwe adzakhudzidwa ndi chiletsochi, ndikofunikira kuyamba kufunafuna njira zina. Kuwunika kwa EPA kwa njira zina m'malo mwa methylene chloride kunapeza njira zina zogwiritsira ntchito zosiyanasiyana monga zomatira, zotsekera, zochotsera mafuta, zochotsa utoto ndi zokutira, zotsekera, ndi zodzoladzola ndi mafuta. Komabe, ndikofunikira kudziwa kuti palibe njira zina zochiritsira (pakati pa zinthu zina) zomwe zapezeka. Kuwunika kwa njira zina "sikulimbikitsa kuti zinthu zigwiritsidwe ntchito m'malo mwa methylene chloride; m'malo mwake, cholinga chake ndikupereka mndandanda woyimira wa zinthu zina ndi zosakaniza za mankhwala ndi zoopsa zake za methylene chloride kuti zitsimikizire kuti zotsatira zowunikira zikuonedwa ngati njira zina zomwe zingatheke. Zimaganiziridwa ngati gawo la malamulo a TSCA Gawo 6(a) a methylene chloride."
Chodzikanira: Chifukwa cha mtundu wonse wa zosinthazi, zomwe zaperekedwa pano sizingagwire ntchito nthawi zonse, ndipo siziyenera kuchitidwapo kanthu popanda upangiri walamulo kutengera momwe zinthu zilili.
