MAZWIRO EZVINHU ZVINOSVISA MUDZIMBA AKAYEDZWA
Mazana emakemikari uye zvinosvibisa zvakayerwa munzvimbo yekugara yemukati.Chinangwa chechikamu ichi ndechekupfupisa data iripo pamusoro pezvipi zvinosvibisa zviri mudzimba uye kutariswa kwavo.
DATA ROKUSIRIRA KWEZVINHU ZVINOSVISA MUDZIMBA
Kurara nekuratidzwa
Kufumurwa mudzimba kunoumba chikamu chikuru chekuratidzwa kune zvinosvibisa zvinofambiswa nemhepo zvinowanikwa muhupenyu hwemunhu.Vanogona kuita kubva pa60 kusvika 95% yehupenyu hwedu hwese kuratidzwa, iyo 30% inoitika patinorara.Exposures inogona kugadziridzwa nekudzora masosi ezvinosvibisa, kubviswa kwavo kwenzvimbo kana kuteya padanho rekuburitswa, kufefetedza kwese nemhepo isina kusvibiswa, uye kusefa uye kuchenesa mweya.Kuratidzwa kwenguva pfupi uye kwenguva refu kune zvinosvibiswa nemhepo mukati memba zvinogona kukonzeresa njodzi dzehutano hwakanyanya sekutsamwiswa kana kuwedzera kweasthma uye allergy zviratidzo, zvezvirwere zvisingaperi semoyo nemoyo uye matambudziko ekufema, uye zvinogona kusimudza njodzi yekufa nguva isati yakwana.Kune akawanda asina kusvibiswa nemhepo munzvimbo yemukati, senge phthalates muguruva rakagadzika uye endocrine zvinokanganisa muzuva, zvisinei nekuti izvi zvisingakanganiswe nemhepo yekufefetera, hazvifukidzwe muTechnote iyi.
Indoor / kunze
Kuratidzwa mudzimba kune kwakabva kwakasiyana.Izvo zvinosvibisa zvinofambiswa nemhepo zvinoumba zviratidziro izvi zvine matsime kunze nemukati.Zvinhu zvinosvibisa zvine zviwanikwa kunze zvinopinda muhamvuropu yechivako kuburikidza nekutsemuka, maburi, nzvimbo dzinotsvedza nekuvuza, pamwe nepamahwindo akavhurika uye masisitimu emhepo.Kufumurwa kune izvi zvinosvibisa kunoitikawo kunze asi zvine nguva pfupi zvikuru pane yekubuda mumba nekuda kwemaitiro ekuita kwevanhu (Klepeis et al. 2001).Kune akawanda indoor anosvibisa masosi zvakare.Indoor anosvibisa masosi anogona kubuda nguva dzose, episodically, uye nguva nenguva.Zvinyorwa zvinosanganisira midziyo yemumba uye zvigadzirwa, zviitiko zvevanhu, uye kupisa kwemukati.Kuratidzwa kune izvi zvinosvibisa zvinongoitika mumba chete.
Zvinhu zvinosvibisa kunze
Nzvimbo huru dzezvinosvibisa zvine mavambo ekunze zvinosanganisira kupiswa kwemafuta, traffic, shanduko yemhepo, uye zviitiko zvezvinomera zvezvirimwa.Mienzaniso yezvinosvibisa zvinoburitswa nekuda kwemaitiro aya anosanganisira tunhu, kusanganisira mukume;nitrogen oxides;organic compounds senge toluene, benzene, xylenes uye polycyclic anonhuwirira hydrocarbons;uye ozone nezvinhu zvayo.Muenzaniso chaiwo wetsvina ine mavambo ekunze iradon, gasi remwaranzi remusikirwo rinobuda mune imwe ivhu rinopinda muchimiro chezvivakwa kuburikidza nekutsemuka kwehamvuropu uye kumwe kuvhurika.Ngozi yekusangana neradon inzvimbo-inotsamira mamiriro kune geological chimiro chenzvimbo inovakwa chivakwa.Radon kuderedza haizokurukurwa mumutumbi weTechNote iripo.Nzira dzekudzikisa radon, dzakazvimiririra pamazinga emhepo, dzakanyatsoongororwa kumwe kunhu (ASTM 2007, WHO 2009).Nzvimbo huru dzezvinosvibisa zvine mavambo emumba zvinosanganisira vanhu (senge bioeffluents) uye zviitiko zvavo zvine chekuita nehutsanana (semuenzaniso kushandiswa kwechigadzirwa cheaerosol), kuchenesa imba (semuenzaniso kushandiswa kwechlorine nezvimwe zvigadzirwa zvekuchenesa), kugadzira chikafu (sekubikira kuburitsa zvidimbu), nezvimwe. .;zvekuvakisa zvinosanganisira fenicha uye zvekushongedza zvinhu (eg formaldehyde emissions kubva mumidziyo);kuputa fodya nekupisa kunoitika mukati memba, pamwe chete nemhuka dzinovaraidza (eg allergens).Kusabata zvisizvo kwekuisa senge mhepo isina kuchengetedzwa zvakanaka kana masisitimu ekudziya kunogonawo kuve kwakakosha kunosvibisa kunobva mukati memba.
