Umgangatho woMoya oPhakathi

Umgangatho womoya ngaphakathi emakhaya, ezikolweni nakwezinye izakhiwo unokuba yinxalenye ebalulekileyo yempilo yakho kunye nokusingqongileyo.

Umgangatho woMoya wangaphakathi kwiiofisi nakwezinye izakhiwo ezinkulu

IRadon

Igesi yeradon yenzeka ngokwendalo kwaye inokubangela umhlaza wemiphunga. Uvavanyo lweradon lulula, kwaye kukho iindlela zokulungisa amanqanaba aphezulu.

• Umhlaza wemiphunga ubulala amawaka abantu baseMelika minyaka le. Ukutshaya, i-radon, kunye nomsi osetyenziswa ngabanye zezona zinto ziphambili ezibangela umhlaza wemiphunga. Nangona umhlaza wemiphunga unokunyangeka, izinga lokusinda lelona liphantsi kwabo banomhlaza. Ukususela ngexesha lokufunyaniswa kwesi sifo, phakathi kwe-11 kunye ne-15 ekhulwini labo banesifo baya kuphila ngaphaya kweminyaka emihlanu, kuxhomekeke kwiimeko zabantu. Kwiimeko ezininzi umhlaza wemiphunga unokuthintelwa.
• Ukutshaya yeyona nto iphambili ebangela umhlaza wemiphunga. Ukutshaya kubangela ukufa kwabantu abamalunga ne-160,000* ababulawa ngumhlaza e-US minyaka le (i-American Cancer Society, 2004). Kwaye izinga phakathi kwabasetyhini liyanda. Ngomhla we-11 kweyoMqungu, ngo-1964, uGqr. Luther L. Terry, owayengugqirha wezifo zengqondo wase-US ngelo xesha, wakhupha isilumkiso sokuqala malunga nonxibelelwano phakathi kokutshaya nomhlaza wemiphunga. Umhlaza wemiphunga ngoku udlula umhlaza webele njengoyena nobangela wokuqala wokufa phakathi kwabasetyhini. Umntu otshayayo okwachaphazeleka yi-radon usengozini enkulu yomhlaza wemiphunga.
• I-Radon yeyona nto iphambili ebangela umhlaza wemiphunga kubantu abangatshayiyo, ngokutsho koqikelelo lwe-EPA. Ngokubanzi, i-radon yeyona nto yesibini ebangela umhlaza wemiphunga. I-Radon ibangela ukufa kwabantu abamalunga nama-21,000 abanesifo somhlaza wemiphunga minyaka le. Malunga nama-2,900 kwaba bantu bafayo ayenzeka kubantu abangazange batshaye.

I-carbon monoxide

Ityhefu ye-carbon monoxide yimbangela yokufa enokuthintelwa.

I-Carbon monoxide (CO), igesi engenavumba, engenambala. Iveliswa nanini na xa i-fossil fuel itshiswa kwaye inokubangela ukugula nokufa ngequbuliso. I-CDC isebenzisana namaqabane esizwe, ephondo, asekuhlaleni, kunye namanye amazwe ukuphakamisa ulwazi malunga nokutyhefwa yi-CO kunye nokubeka esweni idatha yokugula kunye nokufa enxulumene ne-CO eMelika.

Umsi wecuba osingqongileyo / umsi osetyenzisiweyo

Umsi ocuthwa ngumntu omnye ubeka emngciphekweni iintsana, abantwana kunye nabantu abadala.

• Akukho nqanaba likhuselekileyo lokuchatshazelwa ngumsi osetyenziswa ngomnye umntu. Abantu abangatshayiyo abachatshazelwa ngumsi osetyenziswa ngomnye umntu, nokuba lixesha elifutshane, banokufumana iziphumo eziyingozi empilweni.1,2,3
• Kubantu abadala abangatshayiyo, ukutshaya umsi ophuma kwabanye abantu kunokubangela isifo sentliziyo, isifo sohlangothi, umhlaza wemiphunga, nezinye izifo. Kunokubangela nokufa kwangethuba.1,2,3
• Ukutshaya umsi osetyenziswa ngabanye abantu kunokubangela iziphumo ezibi kwimpilo yokuzala kwabasetyhini, kuquka ukuzalwa benobunzima obuphantsi.1,3
• Kubantwana, ukutshaya umsi osetyenziswa ngabanye abantu kunokubangela izifo zokuphefumla, izifo zendlebe, kunye nokuhlaselwa sisifo sesifuba. Kubantwana, ukutshaya komsi osetyenziswa ngabanye abantu kunokubangela isifo sokufa kweentsana ngesiquphe (SIDS).1,2,3
• Ukususela ngo-1964, abantu abamalunga ne-2,500,000 ababengatshayi bafa ngenxa yeengxaki zempilo ezibangelwa kukutshaya umsi osetyenziswa ngabanye abantu.1
• Iziphumo zokutshaya umsi womntu otshayayo emzimbeni zikhawuleza.1,3 Ukutshaya umsi womntu otshayayo kunokuvelisa iziphumo eziyingozi zokudumba kunye nokuphefumla kwimizuzu engama-60 emva kokutshaya, nto leyo enokuhlala ubuncinane iiyure ezintathu emva kokutshaya.4
