Benzene isina mvura isina kupisa, inopisa zvinowanzovapo mumarata emarasha, mafuta asina kuchena, uye senzvimbo yekuputika kwemakomo uye moto wemoto. Iyo ine kunhuhwirira kwakanaka uye inoputika nokukurumidza kana ichitaura kumhepo.
Benzene inorongedzerwa neInternational Agency for Research on Cancer seboka revanhu revanhu.
Benzene iri pakati pemakemikari anoshandiswa zvikuru kwazvo 20 muzvigadzirwa muUnited States nhasi.
Inonyanya kushandiswa kuita mamwe makemikari, akadai se:
- nylon

Nhamba ye benzene mu petrool inoderedzwa mumakore achangopfuura achitevera mitemo yakagadzirirwa MSAT (Mobile Source Air Toxics) neIvironment Protection Agency. Nhamba yeBenene inotumirwa nemotokari inopera uye mapeji emhepo inofanira kuva matani 61 000 pasi pe2030 nekuda kwezvibvumirano zveMSAT. Izvi zvichange zvakakodzera mune zvimwe zvezvivako zvitsva izvo zvisingabudisi zvakasvibiswa zvakanyanya zvemafuta emhepo mumhepo. Nhamba ye benzene mu petrool ichave yakaderera ne38 muzana zvakare.
Benzene muCigarette Smoke
Benzene is-a-product of the combustion of fuggy in cigarettes.
Kusuruvara kune utsi hwefodya kunokonzera hafu yevanhu vose kusvibiswa kwehuputi iyi muUnited States.
Benzene inonyanya kuoma. Nzira huru yekutsvaga ndeyekuputira.
Utsi hwebhegi hunobatsirawo vazhinji veBenene vari munzvimbo dzomukati.

Iyo Benzene Inobata Sei Utano Hwevanhu?
Nguva yakareba (gore kana kupfuura) kufanana neBenene kunogona kuunza kuchinja muropa. Inoderedza masero matsvuku eropa uye inokanganisa bone marora. Izvi zvinokonzera vanhu pangozi yeuplastic anemia nekuwedzerwa ropa.
Benzene inobatanidza nehuwandu hwehutachiwana hwehuukemukari, kunyanya, muteyi myeloid yeukemia. Pane kunetseka kuti benzene inogonawo kuita kuti pave nechirwere uye chisingaperi chine lymphocytic leukemia, kwete Hodgkin's lymphoma uye multiple myeloma.
Kubudiswa kweBenzene kunogona kuderedza masimba emuviri nokuti inokanganisawo masero eropa. Izvi zvinoisa vanhu pangozi kwehutachiwana hwakawanda.
Mimwe Migumisiro Yokuratidzwa
Kunyange zvazvo zvisingashamisi kuonana nepamusoro weBenene kamwechete kamwechete, rudzi urwu rwekutsvaira kuburikidza nekuputika kana kupisa kunokanganisa nheyo yepamusoro yenheyo uye kunogona kutungamirira kune zvimwe zviratidzo zvinoshamisa:
- kuora mitezo
- coma
- kunetseka
- chizoro
- hope
- kukurumidza mwoyo kukurumidza
- kuoma mubhokisi
- kudengenyeka
- kufema kufema
Kana iwe uchifunga kuti wakambosangana nebenene mune imwe nzvimbo yakapoteredzwa, enda panze kumhepo itsva pakarepo. Kana iyo benzene yakabudiswa kunze, famba kure kure nenharaunda sezvaunokwanisa.
Bvisa zvipfeko zvako zvose nekukurumidza kushambidza muviri wako nesipo nemvura pakarepo iwe unogona.
Kana iwe ukamedza bhenene, usaedza kuedza kurutsa kana kunwa mvura. Vomit inogona kuyamwa mumapapu uye kukanganisa mapapu emapapu.
