General Indoor Air Quality

Izinga lomoya ngaphakathi ezindlini, ezikoleni, nakwezinye izakhiwo lingaba isici esibalulekile sempilo yakho nendawo ezungezile.

Ikhwalithi Yomoya Wasendlini Emahhovisi nakwezinye Izakhiwo Ezinkulu

Izinkinga zekhwalithi yomoya wangaphakathi (IAQ) azigcini emakhaya kuphela. Eqinisweni, izakhiwo eziningi zamahhovisi zinemithombo ebalulekile yokungcoliswa komoya. Ezinye zalezi zakhiwo kungenzeka zingenawo umoya okwanele. Isibonelo, amasistimu okungenisa umoya ayimishini angase angaklanywa noma asetshenziswe ukuze anikeze amanani anele omoya wangaphandle. Okokugcina, abantu ngokuvamile abakwazi ukulawula indawo yasendlini emahhovisi abo kunasemakhaya abo. Ngenxa yalokho, kube nokwanda kwezigameko zezinkinga zempilo ezibikiwe.

I-Radon

Igesi ye-radon yenzeka ngokwemvelo futhi ingabangela umdlavuza wamaphaphu. Ukuhlola i-radon kulula, futhi ukulungiswa kwamazinga aphakeme kuyatholakala.

Umdlavuza wamaphaphu ubulala izinkulungwane zabantu baseMelika minyaka yonke. Ukubhema, i-radon, nentuthu kagwayi yizona zimbangela eziphambili zomdlavuza wamaphaphu. Nakuba umdlavuza wamaphaphu ungelapheka, izinga lokusinda lingelinye eliphansi kakhulu kulabo abanomdlavuza. Kusukela ngesikhathi sokuxilongwa, phakathi kwamaphesenti angu-11 no-15 alabo abahlushwayo bazophila ngaphezu kweminyaka emihlanu, kuye ngezici zezibalo. Ezimweni eziningi umdlavuza wamaphaphu ungavinjelwa.
Ukubhema kuyimbangela ehamba phambili yomdlavuza wamaphaphu. Ukubhema kubangela ukufa komdlavuza okulinganiselwa ku-160,000* e-US minyaka yonke (American Cancer Society, 2004). Futhi izinga phakathi kwabesifazane liyakhuphuka. Ngo-January 11, 1964, uDkt. Luther L. Terry, ngaleso sikhathi owayenguDokotela Omkhulu Wokuhlinza Wase-US, wakhipha isixwayiso sokuqala mayelana nokuhlobana phakathi kokubhema nomdlavuza wamaphaphu. Umdlavuza wamaphaphu manje usudlula umdlavuza webele njengembangela yokuqala yokufa kwabesifazane. Umuntu obhemayo naye ochayeke ku-radon unengozi enkulu kakhulu yomdlavuza wamaphaphu.
I-radon iyimbangela yokuqala yomdlavuza wamaphaphu kubantu abangabhemi, ngokwezilinganiso ze-EPA. Sekukonke, i-radon iyimbangela yesibili ehamba phambili yomdlavuza wamaphaphu. I-Radon inesibopho sokufa komdlavuza wamaphaphu okungaba ngu-21,000 minyaka yonke. Cishe i-2,900 yalokhu kufa kwenzeka kubantu abangakaze babheme.

I-carbon monoxide

Ubuthi be-carbon monoxide yimbangela yokufa engagwemeka.

I-Carbon monoxide (CO), igesi engenaphunga, engenambala. Ikhiqizwa noma nini lapho kushiswa amafutha emvelo futhi ingabangela ukugula nokufa kungazelelwe. I-CDC isebenza nozakwethu kazwelonke, wesifunda, wendawo, nabanye ukuze baqwashise abantu mayelana nobuthi be-CO kanye nokuqapha idatha ehlobene nokugula okuhlobene ne-CO kanye nokubhekwa kokushona e-US.

Intuthu kagwayi yemvelo / intuthu kagwayi

Intuthu kagwayi iyingozi ezinsaneni, ezinganeni nakubantu abadala.

Alikho izinga eliphephile lokuchayeka entuthuni kagwayi. Abantu abangabhemi abachayeka ekubhemeni kukagwayi, ngisho isikhathi esifushane, bangaba nemiphumela eyingozi empilweni.1,2,3
Kubantu abadala abangabhemi, ukuhogela intuthu kagwayi kungabangela isifo senhliziyo, unhlangothi, umdlavuza wamaphaphu nezinye izifo. Kungase futhi kubangele ukufa ngaphambi kwesikhathi.1,2,3
Ukubhema kukagwayi kungabangela imiphumela emibi yezempilo yokuzala kwabesifazane, kuhlanganise nesisindo sokuzalwa esiphansi.1,3
Ezinganeni, ukuchayeka kwentuthu kagwayi kungabangela izifo zokuphefumula, izifo ezindlebeni, nokuhlaselwa yisifuba somoya. Ezinganeni, ukubhema kukagwayi kungabangela ukufa kwezingane ezisanda kuzalwa (SIDS).1,2,3
Kusukela ngo-1964, abantu abangaba ngu-2 500 000 ababengabhemi bafa ngenxa yezinkinga zempilo ezibangelwa ukubhema ugwayi.1
Imiphumela yokuchayeka kwentuthu kagwayi emzimbeni ngokushesha.1,3 Ukuchayeka kwentuthu kagwayi kungaveza imiphumela eyingozi yokuvuvukala nokuphefumula phakathi nemizuzu engu-60 yokuchayeka okungahlala okungenani amahora amathathu ngemva kokuchayeka.4
