Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Dzidziso yeformaldehyde yecarcinogenesis yakatangwa muna 1978. Muna 1987 EPA yeU.S. yakachirondedzera sechinhu chinogona kukonzera kenza yevanhu, uye pashure pedzimwe fundo WHO International Agency for Research on Cancer (IARC) muna 1995 yakachirondedzerawo sechinhu chinogona kukonzera kenza yevanhu. Mamwe mashoko uye kuongororwa kwedata rose rinozivikanwa kwakaita kuti IARC idzokorore formaldehyde sechinhu chinozivikanwa chinokonzera kenza yevanhu chinobatanidzwa nekenza yemhino yemhino nekenza yemhino. Zvidzidzo zvomuna 2009 na2010 zvakaratidzawo kuwirirana kwakanaka pakati pokubatwa neformaldehyde uye kukura kweleukemia, zvikurukuru myeloid leukemia. Kenza yemhino nemhino isingawanzoitiki, ine kuwanda kwegore negore kwakabatana muUnited States kwe < zviitiko 4 000. Vanhu vanenge 30 000 vane myeloid leukemia vanoitika muUnited States gore roga roga. Kutapurirwa kunzvimbo yebasa kumakemikoro anofemerwa kuri pakati pezvinhu zvinokosha zvikurusa zvinoparira kenza dzesinus nasal. Vashandi vanobatwa neformaldehyde mubasa ravo, vakadai sevashandi vemumigwagwa yemariro nevanobika zvitunha, vakawedzera ngozi yokubatwa nechirwere cheleukemia nekenza yomuuropi kana vachienzaniswa nevamwe vanhu vose. Zvimwe zvinhu zvinokosha pakusarudza njodzi yomunhu oga yokuva nechirwere cheleukemia kana kuti kenza yemhino. Munzvimbo dzokugara, formaldehyde inobva munzira dzakasiyana-siyana; formaldehyde inogona kubuda mumiti yemapuranga, yakadai seplywood kana kuti particle board, asi inogadzirwa nemapendi, varnish, kupedzisa pasi, uye kusvuta fodya. Muna Chikunguru 2016, iyo EPA yakaburitsa pre-kuburitswa vhezheni yemutemo wayo wekupedzisira pane Formaldehyde Emission Standards yeComposite Wood Zvigadzirwa. Iyi mitemo mitsva inokanganisa vagadziri, vatengesi, vatengesi, uye vatengesi vezvinhu zvine matanda akaumbwa, kusanganisira fiberboard, particleboard, uye zvigadzirwa zvakasiyana-siyana zvakagadzirwa, izvo zvinofanira kutevedzera zvinyorwa zvakaomarara zvekuchengetedza uye zvinyorwa.United States Environmental Protection Agency (EPA) inobvumira kwete kupfuura 0.016 ppm formaldehyde mumhepo muzvivako zvitsva zvakavakwa...  Mubvunzo: formaldehyde inorondedzerwa sei?
