Sangano reEnvironmental Protection Agency rakaronga kurambidza kushandiswa kwemethylene chloride, kemikari yavanoti ine njodzi kuhutano uye inotouraya, kuchengetedza hutano hweveruzhinji.
Chirongwa ichi chaizorambidza kushandiswa kwe dichloromethane mumamiriro ese ezvinhu evatengi uye mumabasa mazhinji emaindasitiri nemabhizimisi. Dichloromethane inoshandiswa mukubvisa mafuta muaerosol, mukuchenesa mabhurashi ekupenda nekupenda, muzvinamira zvemabhizimisi uye muzvinamira, uye mukugadzirwa kwemamwe makemikari munzvimbo dzemaindasitiri.
Kurambidzwa uku kwakatangwa sechikamu cheToxic Substances Control Act, iyo yakapa EPA mukana wekuda kuti inyore, kuchengetwa kwezvinyorwa, uye kuongororwa, pakati pezvimwe zvirambidzo. Muna 2019, EPA yakarambidza kushandiswa kwe dichloromethane nekubvisa kubva muzvimedu zvependi.
Vanhu vanosvika 85 vakafa nekuda kwekushandisa mushonga uyu kubvira muna 1980, sekureva kweEPA. Environmental Protection Agency yakati nyaya idzi dzainyanya kusanganisira vashandi vaishanda pakugadzirisa dzimba. Sangano iri rakati kune vanhu "vakawanda" vakatambura nematambudziko ehutano kwenguva refu mushure mekushandisa methylene chloride. EPA yakaonawo migumisiro yakaipa pahutano, kusanganisira chepfu yeuropi, migumisiro yechiropa, uye kenza kuburikidza nekufema uye kubata ganda.
Sangano iri rakaona kuti dichloromethane inokonzera "njodzi isina musoro yekukuvadza hutano kana ishandiswa" nekuda kwenjodzi kuvashandi vanobatwa nekemikari zvakananga kana zvisina kunanga, vatengi vanoshandisa kemikari, uye vanhu vanobatwa nekemikari.
"Sainzi iri shure kwemethylene chloride yakajeka, uye kusvibiswa kunogona kukonzera migumisiro yakakomba pahutano uye kunyange rufu, izvo zviri kuitika kumhuri dzakawanda dzakarasikirwa nevadikanwi nekuda kwechepfu yakakomba," akadaro musangano weEPA Michael S. Regan. uyo wakazivisa izvozvo. "Ndosaka EPA iri kutora danho nekukurudzira kuchengetedza hutano hwevashandi nekuisa mitemo yakaoma yebasa iyo yaizorambidza kushandiswa kwakawanda kwekemikari iyi uye kuderedza kusvibiswa mune dzimwe mamiriro ese."
EPA yakati chinangwa chekurambidzwa kwakarongwa ndechekudzivirira vanhu kubva panjodzi uye kungobvumira methylene chloride kuti ishandiswe mumamiriro ebasa anotarisirwa zvakanyanya, izvo zvaizoderedza kusvibiswa. Kugadzirwa, kugadziriswa uye kugoverwa kwe dichloromethane kuchamira mukati memwedzi gumi nemishanu inotevera. Pakarambidzwa kemikari iyi, ongororo yeEPA yakawana kuti zvimwe zvigadzirwa "zvine mutengo wakafanana uye zvinoshanda ... zvinowanzo kuwanikwa."
"Kurambidzwa uku kwakarongwa kare kunoratidza kufambira mberi kukuru kwatakaita mukuisa nzira itsva dzekuchengetedza makemikari uye kutora matanho akatorwa nguva refu ekuchengetedza hutano hweveruzhinji zviri nani," akadaro Reagan.
