Volatile organic compounds (VOCs) inobudiswa semagasi kubva kune mamwe makasimba kana zvinwiwa.MaVOCs anosanganisira akasiyana emakemikari, mamwe acho anogona kuve neapfupi-uye kwenguva refu akashata hutano mhedzisiro.Mabatirwo emaVOC mazhinji anogara akakwira mukati (kusvika zvakapetwa kagumi) kupfuura kunze.MaVOC anoburitswa nemhando dzakasiyana dzezvigadzirwa zvinosvika zviuru.

Organic makemikari anoshandiswa zvakanyanya semisanganiswa muzvigadzirwa zvemumba.Pendi, mavarnish uye wakisi zvese zvine organic solvents, sezvinoita akawanda ekuchenesa, disinfecting, cosmetic, degreasing uye hobby zvigadzirwa.Mafuta anogadzirwa nemakemikari ane organic.Zvese zvigadzirwa izvi zvinogona kuburitsa organic komisheni iwe uchiishandisa, uye, kune imwe nhanho, kana zvachengetwa.

EPA's Hofisi Yekutsvagisa neBudiriro ye "Total Exposure Assessment Methodology (TEAM) Study" (Mavhoriyamu I kusvika IV, akapedzwa muna 1985) yakawana mazinga anosvika gumi nemaviri akajairika anosvibisa organic kuve 2 kusvika 5 yakakwira mukati medzimba kupfuura kunze, zvisinei kuti dzimba dzacho dzakanga dziri mumaruwa kana kuti nzvimbo dzine maindasitiri makuru.Zvidzidzo zveTEAM zvakaratidza kuti nepo vanhu vari kushandisa zvigadzirwa zvine organic makemikari, vanogona kuzviratidza ivo nevamwe kune yakanyanya kusvibiswa mwero, uye kukwirisa kwakanyanya kunogona kuramba kuri mumhepo mushure mekunge basa rapera.

Zvinyorwa zveVOCs

Zvigadzirwa zvemumba, zvinosanganisira:

• pendi, pendi strippers nezvimwe zvinonyungudutsa
• matanda ekuchengetedza
• aerosol sprays
• mishonga yekuchenesa nemishonga inouraya utachiona
• zvinodzinga zvipfukuto uye zvinofefetera mhepo
• mafuta akachengetwa uye zvigadzirwa zvemotokari
• hobby zvinhu
• nguo dzakaoma-dzakacheneswa
• mushonga wezvipembenene

Zvimwe zvigadzirwa, zvinosanganisira:

• zvokuvakisa uye fenicha
• midziyo yemuhofisi yakaita semakopi nemaprinta, zvinwiwa zvekugadzirisa uye mapepa asina kabhoni
• magirafu uye zvekugadzira zvinosanganisira glues uye zvinonamira, zvisingaperi mamaki uye mafoto mhinduro.

Utano Migumisiro

Migumisiro yehutano inogona kusanganisira:

• Kushatirwa kweziso, mhuno nehuro
• Musoro, kurasikirwa kwekubatana uye kusvotwa
• Kukuvadza kwechiropa, itsvo uye central nervous system
• Mamwe ma organics anogona kukonzera gomarara mumhuka, mamwe anofungidzirwa kana anozivikanwa kuti anokonzera gomarara muvanhu.

Zviratidzo zvakakosha kana zviratidzo zvine chekuita nekufumurwa kuVOCs zvinosanganisira:

• conjunctival irritation
• kusagadzikana kwemhino nehuro
• musoro
• allergic skin reaction
• dyspnea
• kuderera kwemazinga e serum cholinesterase
• kuda kurutsa
• emesis
• epistaxis
• kuneta
• dzungu

Kugona kwemakemikari emakemikari kukonzeresa hutano kunosiyana zvakanyanya kubva kune ayo ane muchetura zvakanyanya, kune avo vasina kuzivikanwa hutano maitiro.

Sezvimwe nezvimwe zvinosvibisa, hukuru uye chimiro chehutano hwehutano hunoenderana nezvinhu zvakawanda zvinosanganisira chiyero chekuratidzwa uye urefu hwenguva yakafumurwa.Pakati pezviratidzo zvinoonekwa nevamwe vanhu nguva pfupi mushure mekusangana kune mamwe organics zvinosanganisira:

• Kushatirwa kweziso nekufema
• kutemwa nemusoro
• dzungu
• kusaona zvakanaka uye kukanganisa kuyeuka

Parizvino, hapana zvakawanda zvinozivikanwa nezve izvo hutano mhedzisiro inoitika kubva kumatanho e organics anowanzo kuwanikwa mudzimba.

Levels Mudzimba

Zvidzidzo zvakawana kuti mazinga ezvakawanda organics avhareji 2 kusvika 5 nguva dzakakwirira mukati mukati kupfuura kunze.Munguva uye kwemaawa akati kuti pakarepo mushure mezvimwe zviitiko, zvakadai sekubvisa pendi, mazinga anogona kunge ari 1,000 nguva kumashure kwekunze kwemazinga.

Matanho ekuderedza Kufumurwa

• Wedzera kufefetera kana uchishandisa zvigadzirwa zvinoburitsa VOCs.
• Sangana kana kudarika chero label precautions.
• Usachengete midziyo yakavhurwa yependi isina kushandiswa uye zvimwe zvakafanana mukati mechikoro.
• Formaldehyde, imwe yeanonyanya kuzivikanwa maVOCs, ndeimwe yeashoma anosvibisa mhepo mukati anogona kuyerwa zviri nyore.
  • Ziva, uye kana zvichiita, bvisa kwabva.
  • Kana zvisingaiti kubvisa, kuderedza kuratidzwa nekushandisa sealant pane ese akafumurwa nzvimbo dzepaneling uye zvimwe midziyo.
• Shandisa nzira dzakabatanidzwa dzekuchengetedza zvipembenene kuderedza kudiwa kwemishonga.
• Shandisa zvigadzirwa zvemumba zvinoenderana nemirairo yemugadziri.
• Ita shuwa kuti unopa mweya mutsva wakawanda paunenge uchishandisa zvigadzirwa izvi.
• Rasa midziyo isina kushandiswa kana zvishoma-yakashandiswa zvakachengeteka;tenga muhuwandu hwauchashandisa nekukurumidza.
• Chengetedza kure nevana nemhuka dzinovaraidza.
• Usambosanganise zvigadzirwa zvekuchengetedza mhuri kunze kwekunge zvarairwa pazita.

Tevedzera mirairo yemalebula zvakanaka.

Zvigadzirwa zvingangove nengozi kazhinji zvine yambiro ine chinangwa chekudzikisa kuratidzwa kwemushandisi.Semuenzaniso, kana chikwangwani chikati shandisa chigadzirwa munzvimbo inofefetera zvakanaka, enda kunze kana munzvimbo dzakashongedzerwa nemhepo inopedza simba kuti uishandise.Zvikasadaro, vhura mahwindo kuti upe huwandu hwakanyanya hwemhepo yekunze inogoneka.

Rasa midziyo inenge yakazara makemikari ekare kana asingadikanwi zvakachengetedzeka.

Nekuti magasi anogona kudonha kunyangwe kubva mumidziyo yakavharwa, nhanho imwe chete iyi inogona kubatsira kudzika kwakadzika kwemakemikari emumba mumba mako.(Iva nechokwadi chokuti zvinhu zvaunosarudza kuchengeta zvinochengetwa kwete bedzi munzvimbo inofefetera mhepo yakanaka chete asiwo zvakakotsekana kusingasvikiki nevana.) Usangokanda zvinhu izvi zvisingadiwi mugaba remarara.Tsvaga kana hurumende yako yemuno kana chero sangano munharaunda yako richitsigira mazuva akakosha ekuunganidzwa kwemarara emumba ane muchetura.Kana mazuva akadai aripo, ashandise kurasa midziyo yausingadi zvisina njodzi.Kana pasina mazuva ekuunganidza akadaro aripo, funga nezvekuronga imwe.

Tenga zvishoma.

Kana ukashandisa zvigadzirwa pano neapo kana mwaka, zvakaita sependi, pendi, zvimisikidza pendi neparafini pazvidziya zvemuchadenga kana peturu yevanocheka uswa, tenga chete yakawanda yauchazoshandisa ipapo ipapo.

Chengetedza kuratidzwa kune zvinobuda kubva kune zvigadzirwa zvine methylene chloride kusvika zvishoma.

Zvigadzirwa zvevatengi zvine methylene chloride zvinosanganisira pendi strippers, adhesive removers uye aerosol spray pendi.Methylene chloride inozivikanwa kuti inokonzera gomarara mumhuka.Zvakare, methylene chloride inoshandurwa kuita kabhoni monoxide mumuviri uye inogona kukonzera zviratidzo zvine chekuita nekusangana nekabhoni monoxide.Nyatsoverenga mavara ane ruzivo rwengozi yehutano uye yambiro pamusoro pemashandisirwo akanaka ezvigadzirwa izvi.Shandisa zvigadzirwa zvine methylene chloride kunze kana zvichibvira;shandisa mumba chete kana nzvimbo yacho yakanyatsofefeterwa.

Ramba uchisangana nebenzene zvishoma.

Benzene inozivikanwa kenza yemunhu.Nzvimbo huru dzemukati mekemikari iyi ndeidzi:

• utsi hwefodya yezvakatipoteredza
• mafuta akachengetwa
• pendi zvinhu
• kubudiswa kwemotokari mumagaraji akabatanidzwa

Zviito zvinoderedza kuratidzwa kwebenzene zvinosanganisira:

• kubvisa kusvuta mumba
• kupa mhepo yakawanda panguva yekupenda
• kurasa zvinhu zvependi nemafuta chaiwo asingazo shandiswe nekukasika

Chengetedza kuratidzwa kune perchlorethylene emissions kubva kuchangobva kuoma-yakacheneswa zvinhu kusvika kushoma.

Perchlorethylene ndiyo kemikari inonyanya kushandiswa mukuchenesa yakaoma.Muzvidzidzo zvemurabhoritari, zvakaratidzwa kukonzera kenza mumhuka.Ongororo dzichangobva kuitika dzinoratidza kuti vanhu vanofema mwero wakaderera wekemikari iyi mudzimba umo zvinhu zvakacheneswa zvakaomeswa zvinochengeterwa uye sezvavanopfeka zvipfeko zvakacheneswa.Dry cleaners inotorazve perchlorethylene panguva yakaoma-yekuchenesa nzira kuitira kuti vachengetedze mari nekuishandisa zvakare, uye vanobvisa mamwe emakemikari panguva yekutsikirira uye kupedza maitiro.Mamwe makuchenesa akaoma, zvisinei, haabvise perchlorethylene yakawanda sezvinobvira nguva dzose.

Kutora matanho ekuderedza kuratidzwa kwako kune iyi kemikari zvine hungwaru.

• Kana zvinhu zvakacheneswa zvakaoma zvine kunhuhwirira kwakasimba kwemakemikari paunozvinhonga, usazvigamuchira kusvikira zvanyatsoomeswa.
• Kana zvinhu zvine kunhuhwirira kwemakemikari zvikadzoserwa kwauri pakushanya kunotevera, edza imwe dry cleaner.
