Cov kab mob thiab plua plav mites

Tsuav yog muaj cov dej noo thiab cov organic teeb meem, nws yog qhov yooj yim heev rau cov kab mob, kab mob, pwm thiab lwm yam kab mob kom loj hlob, xws li ntawm cov iav qhov chaw, hauv cov khoom siv hauv tsev, hauv cov kab nrib pleb hauv phab ntsa, ntawm cov ntoo panels, thiab txawm tias ntawm cov ntsaws. ntawm tus nqi roj av cartridges ntawm cov dav hlau dav hlau.Plua plav mites, ntawm qhov tod tes, nyiam moist thiab sov thiab loj hlob feem ntau ntawm cov plua plav, txaj, hauv ncoo, sofas thiab cov rooj zaum, khaub ncaws, khoom noj, thiab lwm yam. Ob leeg nyob thiab tuag mites, thiab txawm lawv cov tawv nqaij molted los yog excrement, yog antigenic. thiab tuaj yeem ua rau mob hawb pob lossis khaus khaus.

Formaldehyde

Cov tshuaj formula CH2O, lus Askiv lub npe Formalin, cov pa roj uas muaj ntxhiab tsw ntxhiab, gaseous nyob rau hauv chav tsev kub, siab toxicity, yog ib tug lees paub qhov chaw ntawm perverted tshuaj lom neeg, txheeb xyuas los ntawm World Health Organization raws li ib tug chav kawm ntawv I carcinogen (ie, carcinogenic rau tib neeg thiab tsiaj), kuj yog ib tug muaj zog mutagen, nyob rau hauv Tuam Tshoj tus thawj tswj daim ntawv teev cov tshuaj lom nyob rau hauv lub thib ob qhov chaw (thawj yog dioxin).Txawm li cas los xij, kev siv ntau ntawm formaldehyde hauv kev lag luam tau ua rau nws muaj kuab paug loj rau tib neeg kev noj qab haus huv hauv tsev, tshwj xeeb tshaj yog nyob rau hauv huab cua.Formaldehyde feem ntau yog los ntawm kev kho kom zoo nkauj sab hauv thiab cov ntaub ntawv zoo nkauj.Ntoo txiv neej ua panels xws li nplaum, plywood, joinery, MDF thiab particle board siv rau kho kom zoo nkauj sab hauv.Kev tshawb fawb los ntawm Yokohama National University hauv Nyij Pooj qhia tau hais tias lub sijhawm tso tawm ntawm formaldehyde nyob rau hauv cov txiv neej ua vaj huam sib luag feem ntau yog 3-15 xyoo.Tsis tas li ntawd, cov ntaub pua tsev, cov ntaub pua tsev chemical, cov vuas yas pem teb, ua npuas ncauj, pleev xim, lacquers thiab thinners kuj muaj qee yam ntawm formaldehyde.

PM 2.5

PM2.5 tsis yog 2.5 teev tsaus ntuj, yog cov ntawv luv ntawm Cov Khoom Siv Hluav Taws Xob, hais txog huab cua tsawg dua lossis sib npaug ntawm 2.5 microns hauv txoj kab uas hla (1 hli = 1000 microns), nws PM2.5 cov lus tau txais kev saib xyuas vim tias lawv muaj me me rau ncaj qha nkag mus rau hauv lub ntsws thiab txawm cov ntshav, thiab vim hais tias lawv muaj peev xwm ua tau ib tug cab kuj ntawm cov kab mob thiab kab mob parasites, thiab yog li ntawd muaj peev xwm ua mob loj.

Benzene

benzenes muaj nyob rau hauv ntau qhov ntau hauv cov kuab tshuaj organic siv nyob rau hauv ntau yam khoom siv hauv tsev, xws li cov khoom siv ntxiv rau cov xim thiab cov coatings, thinners, thiab qee cov ntaub ntawv waterproofing.Cov rooj tog tsis zoo kuj tuaj yeem tso VOCs xws li benzene.Wallpaper, pem teb tawv, plywood thiab xim yog ib qho ntawm cov khoom tseem ceeb ntawm cov pa roj carbon monoxide muaj kuab paug nyob hauv tsev.Kev nqus pa ntawm cov benzene ntau ntau hauv lub sijhawm luv luv tuaj yeem ua rau mob benzene lom nrog lub hauv paus paj hlwb kev nyuaj siab uas yog lub hauv paus ua rau, kiv taub hau, mob taub hau, xeev siab, hauv siab nruj, tsis muaj zog, thiab qhov muag plooj tsis nco qab hauv cov mob me: hauv cov mob hnyav. , coma lossis txawm ua pa thiab circulatory tsis ua haujlwm thiab tuag.Lub sij hawm ntev raug rau qhov tsis tshua muaj siab ntawm benzene tuaj yeem ua rau mob lom, kiv taub hau, insomnia, kev nyuaj siab, nco tsis tau thiab lwm yam kev puas hlwb, tab sis kuj tshwm sim raws li daim tawv nqaij, qhov muag thiab lub ntsws ua pa sab sauv, platelet, txo cov qe ntshav dawb, mob hnyav. tuaj yeem ua rau cov pob txha pob txha hematopoietic tsis ua haujlwm, kev ua menyuam yaus kuj muaj qee yam cuam tshuam.Benzene yog ib yam kab mob loj heev.

Hauv tsev radon

Nyob rau hauv tsab ntawv ceeb toom ntawm United Nations Scientific Committee on Atomic Radiation Effects nyob rau hauv 1982, nws tau taw qhia tias cov ntaub ntawv tsim kho yog qhov tseem ceeb tshaj plaws ntawm radon sab hauv tsev.Xws li granite, cib xuab zeb, cement thiab gypsum, tshwj xeeb tshaj yog cov pob zeb ntuj uas muaj cov khoom siv hluav taws xob, yooj yim tso tawm radon.Ntau hom pob zeb muaj cov xov tooj cua sib txawv vim lawv cov keeb kwm, geological qauv thiab tiam neeg.Lub Xeev Lub Chaw Haujlwm Saib Xyuas Kev Ua Zoo thiab Kev Saib Xyuas Kev Ua Haujlwm tau ua kev saib xyuas thiab kuaj xyuas cov pob zeb ntuj hauv khw.Radon tau lees paub tias yog tib neeg carcinogen los ntawm International Agency for Research on Cancer.Ntawm cov xwm txheej ua rau mob qog noj ntshav, radon tau teev tseg yog qhov thib ob tom qab haus luam yeeb.Cov hluav taws xob hluav taws xob tuaj yeem cuam tshuam rau tib neeg cov hlab ntsha, kev loj hlob, kev mob plawv, kev tiv thaiv kab mob thiab qhov muag.Lub pob zeb ntuj kuj muaj qee yam xov tooj cua, nws cov xov tooj cua feem ntau yog cov khoom siv hluav taws xob uas tsim los ntawm radium, thorium thiab potassium peb lub xov tooj cua hauv kev lwj, nws cov teeb meem cuam tshuam yog nyob rau hauv vivo hluav taws xob thiab hauv vitro hluav taws xob.

Volatiles

Tag nrho cov volatile organic tebchaw (TVOC) nyob rau hauv tsev feem ntau yog los ntawm cov xim, dej-raws li xim, nplaum, tshuaj pleev ib ce, detergents, dag boards, wallpapers, ntaub pua plag, thiab lwm yam. TVOCs tau pom nyob rau hauv ntau txhiab hom, muab faib ua yim pawg: alkanes, aromatics. , alkenes, haloalkenes, esters, aldehydes, ketones thiab lwm yam.

Asbestos

Asbestos nws tus kheej tsis muaj tshuaj lom, nws qhov kev puas tsuaj loj tshaj plaws los ntawm nws cov fiber ntau.Qhov no yog qhov me me, yuav luag tsis pom ntawm qhov muag liab qab fibers.Thaum cov fibers me me no nqus tau, lawv tuaj yeem txuas rau thiab tso rau hauv lub ntsws, ua rau cov kab mob ntsws xws li asbestosis thiab cov qog nqaij hlav interdermal ntawm pleura thiab peritoneum;Cov kab mob ntsws no feem ntau muaj lub sijhawm latent ntev.Yog li ntawd, asbestos tau raug txheeb xyuas tias yog cov kab mob carcinogen los ntawm International Agency for Research on Cancer.

Ammonia

Ammonia feem ntau yog los ntawm cov pob zeb sib xyaw siv hauv kev tsim kho vaj tsev: tshwj xeeb tshaj yog thaum lub caij ntuj no tsim kho, cov pob zeb tiv thaiv kab mob nrog urea thiab ammonia raws li cov khoom xyaw tseem ceeb ntxiv rau cov phab ntsa pob zeb.Cov admixtures uas muaj ntau cov tshuaj ammonia raug txo kom ammonia nyob rau hauv cov phab ntsa nrog cov kev hloov ntawm kub thiab av noo thiab lwm yam ib puag ncig thiab maj mam tso tawm ntawm phab ntsa, ua rau ib tug loj nce nyob rau hauv lub concentration ntawm ammonia nyob rau hauv cov huab cua sab hauv tsev.Tsis tas li ntawd, ammonia nyob rau hauv cov huab cua sab hauv kuj tuaj yeem los ntawm cov khoom siv ntxiv thiab cov tshuaj ntxuav hniav dawb hauv cov khoom siv kho kom zoo nkauj sab hauv.Txawm li cas los xij, lub sij hawm tso tawm ntawm cov pa phem no yog qhov ceev ceev, thiab tsis sib sau ua ke hauv huab cua ntev ntev hauv ntau qhov ntau, uas tsis tshua muaj teeb meem rau tib neeg.Ammonia yog cov roj tsis muaj xim nrog cov ntxhiab tsw ntxhiab tsw.Nws yog ib yam khoom alkaline uas corrodes thiab irritates cov ntaub so ntswg nws los ntawm kev sib cuag nrog.Ammonia tuaj yeem nqus dej los ntawm cov ntaub so ntswg, cov ntaub so ntswg denature, thiab saponify cov ntaub so ntswg rog, rhuav tshem cell membrane qauv, thiab ua rau lub cev tsis muaj zog tiv thaiv kab mob.Kev cuam tshuam ntev rau qhov qis qis ntawm ammonia tuaj yeem ua rau lub caj pas thiab lub suab nrov hauv cov teeb meem sib zog, thiab laryngeal edema, laryngeal spasm, thiab txawm tias ua pa nyuaj, pulmonary edema, coma thiab poob siab nyob rau hauv cov mob hnyav dua.Ntxiv nrog rau cov nyhuv corrosive thaum lub concentration siab dhau lawm, nws tuaj yeem ua rau lub plawv nres thiab ua pa nres los ntawm kev ua haujlwm ntawm lub paj hlwb trigeminal.
