Kuj hu ua chloroethylene, ethylene monochloride, los yog monochloroethylene, vinyl chloride yog ib cov roj ntsha uas muaj av zoo los sis kua muaj kua ntxhiab tsw qab. Vinyl chloride yog ib qho khoom tsim los ntawm tib neeg. Nws tsis tshwm sim hauv ib puag ncig.
Siv
Txog rau thaum nruab nrab ntawm mid-raws li cov yas chloride siv ntau yam khoom siv, nrog rau cov tshuaj pleev ib ce, raws li tus ciav hlau nyob hauv aerosol cov kaus poom, thiab ua kom txias.
Niaj hnub no, cov kua chloride feem ntau yog siv los ua ib qho polymer hu ua polyvinyl chloride (PVC). PVC muaj nyob rau hauv ntau yam khoom siv yas, nrog rau cov hlau thaiv thiab cov ntaub ntawv ntim.
Vinyl chloride kuj tau siv rau hauv cov khoom siv ntawm cov yeeb yam luam yeeb.
Ua Li Cas Chloride Tso Rau Hauv Tib Neeg lub Cev
Vinyl chloride feem ntau yuav nkag mus rau hauv tib neeg lub cev los ntawm kev nqhis dej:
- Ua pa cua kom ze rau qhov chaw pov tseg / thaj chaw pov tseg uas cov khib nyiab pov tseg cov khoom pov tseg.
- Ua pa rau hauv qhov chaw ua pa uas muaj kab mob uas tsim los yog siv.
- Nqus pa luam yeeb los sis luam yeeb haus luam yeeb.
Tsawg tshaj, cov chloride yuav noj tau thaum ib tus neeg haus tau dej los ntawm cov kab mob zoo.
Vinyl Chloride hauv cov Cigarettes
Vinyl chloride tuaj yeem pom nyob rau hauv ob qho tib si thiab nqus pa luam yeeb hauv cov qib qis, feem ntau 5 mus rau 30 nanograms ib tus luam yeeb (tus nanogram yog 0.000000001 grams).
Cov kev tshawb fawb ntawm lub sij hawm ntev raug rau cov kua chloride hauv cov tsiaj muaj qhia tau hais tias kev mob siab ntawm lub siab thiab cov caj pas mammary yuav nce thaum qib qis ntawm cov kua chloride tuaj nyob hauv cov huab cua (50 ppm).
Thaum peb tsis paub ntau npaum li cas-hauv pa luam yeeb haus nws yuav siv sij hawm los qhia qhov muaj kev phom sij ntawm cov chloride, peb paub tias nws pab rau kev mob kheesxaws thiab tsis zoo los ua pa ntawm txhua qhov ntau.
Kev Phom Rau Kev Noj Qab Haus Huv
Cov kev txaus ntshai ntawm kev raug mob cov tshuaj chloride yog nyob ntawm ntau yam:
- Tus nqi uas tus neeg tau raug.
- Qhov nquag muaj tsawg.
- Qhov ntev ntawm txhua qhov raug.
- Hom raug; nqus pa lossis hnoos.
Lwm yam tseem ceeb uas yuav tsum tau muab xam rau hauv qhov muaj xws li seb puas muaj lwm yam tshuaj tuaj thaum lub sij hawm raug tus kab mob chloride, nrog rau lub hnub nyoog, kev sib daj sib dee, kev noj haus thiab kev noj qab haus huv tag nrho ntawm tus neeg raug tus kab mob.
Thaum cov kua chloride nkag mus rau hauv cov ntshav, nws mus txog rau lub siab, qhov twg nws tau hloov dua siab tshiab rau lwm cov tshuaj.
Vinyl chloride nws tus kheej feem ntau tawm hauv lub cev ntawm ib hnub ntawm cov zis, tab sis cov tshuaj uas ua rau lub siab ua ntev tshaj tawm hauv lub cev. Qee tus ntawm lawv yog cov muaj kev puas tsuaj rau tib neeg kev noj qab haus huv dua chloride vim lawv tshuaj nrog cov tshuaj feem ntau nyob rau hauv lub cev thiab hloov lawv kev siv / teb rau kev kho mob.
Vinyl Chloride thiab Cancer
Vinyl chloride yuav ua rau kom muaj kev pheej hmoo ntawm kev tsim muaj ntau cov qog nqaij hlav, xws li:
- Mob qog nqaij hlav cancer
- Hlwb mob hlwb
- Mob ntsws cancer
- Lymphoma
- Leukemia
US Dept. ntawm Kev Noj Qab Haus Huv thiab Kev Pab Tib Neeg, Lub Chaw Khiav Dej Num Kev Tshawb Fawb Txog Kev Tshawb Fawb Cancer, thiab Teb Chaws Asmeskas Lub Chaw Ncig Teb Chaws Taw Tsam tau lees paub tias cov tshuaj chloride yog ib tus neeg paub tus kab mob carcinogen.
Xav paub ntau ntxiv ntawm cov Tshuaj hauv Haus luam yeeb
Txog hnub tim, kev tshawb fawb tau pom ntau tshaj 7,000 tshuaj, nrog rau 250 lub cev, thiab 70 cov kab mob carcinogenic hauv cov pa luam yeeb, thiab yuav ua rau tsis paub tseeb ntxiv yav tom ntej.
Yog tias koj tseem haus luam yeeb, thov koj pib taug txoj kev cawm siav ntawm txoj kev haus luam yeeb . Tsis txhob ncua. Pib ntawm koj txoj kev txiav luam yeeb tam sim no. Koj yuav tsis khuv xim nws.
