Umgangatho woMoya ngokubanzi wangaphakathi

Umgangatho womoya ngaphakathi ezindlini, ezikolweni, nakwezinye izakhiwo unokuba ngumba obalulekileyo kwimpilo yakho kunye nokusingqongileyo.

Umgangatho woMoya wangaphakathi kwii-Ofisi kunye nezinye izakhiwo ezikhulu

Iingxaki zomgangatho womoya wangaphakathi (IAQ) azikhawulelwanga kumakhaya kuphela. Enyanisweni, izakhiwo ezininzi zeeofisi zinemithombo ebalulekileyo yongcoliseko lomoya. Ezinye zezi zakhiwo zisenokungangeni moya ngokwaneleyo. Umzekelo, iinkqubo zokuphefumla ngoomatshini azinakuyilwa okanye zisetyenzwe ukuze zibonelele ngezixa ezaneleyo zomoya wangaphandle. Okokugqibela, abantu ngokubanzi banolawulo oluncinci kwindawo yangaphakathi kwiiofisi zabo kunokuba benzayo kumakhaya abo. Ngenxa yoko, kuye kwakho ukwanda kweziganeko zeengxaki zempilo ezixeliweyo.

Iradon

Irhasi yeradon yenzeka ngokwemvelo kwaye inokubangela umhlaza wemiphunga. Uvavanyo lweradon lulula, kwaye ukulungiswa kwamanqanaba aphakamileyo akhona.

Umhlaza wemiphunga ubulala amawaka abantu baseMelika minyaka le. Ukutshaya, iradon, kunye nomsi wecuba ngabona nobangela baphambili bomhlaza wemiphunga. Nangona umhlaza wemiphunga unokunyangwa, izinga lokusinda lelinye lawona asezantsi kwabo banomhlaza. Ukususela kwixesha lokuxilonga, phakathi kwe-11 kunye ne-15 ekhulwini labo babandezelekileyo baya kuphila ngaphaya kweminyaka emihlanu, kuxhomekeke kwizinto zabantu. Kwiimeko ezininzi umhlaza wemiphunga unokuthintelwa.
Ukutshaya ngoyena nobangela uphambili womhlaza wemiphunga. Ukutshaya kubangela ukuba kuqikelelwa ukuba i-160,000 * yokufa komhlaza e-US minyaka yonke (i-American Cancer Society, i-2004). Kwaye izinga phakathi kwabasetyhini liyenyuka. NgoJanuwari 11, 1964, uGqr. Luther L. Terry, owayesakuba nguGqirha Jikelele waseUnited States, wakhupha isilumkiso sokuqala ngonxibelelwano olukhoyo phakathi kwecuba nomhlaza wemiphunga. Umhlaza wemiphunga ngoku wodlula umhlaza wamabele njengoyena nobangela wokuqala wokufa kwabasetyhini. Intshayi ekwachanabeke kwiradon inomngcipheko omkhulu wokuba nomhlaza wemiphunga.
Iradon yeyona nto ibangela umhlaza wemiphunga phakathi kwabantu abangatshayiyo, ngokoqikelelo lwe-EPA. Ngokubanzi, iradon yimbangela yesibini ekhokelayo yomhlaza wemiphunga. I-Radon inoxanduva lokufa komhlaza wemiphunga malunga nama-21,000 ngonyaka. Malunga nama-2,900 kwaba bafayo kwenzeka kubantu abangazange batshaye.

Ikharbhon monoxide

Ityhefu yecarbon monoxide ngunobangela wokufa onokuthinteleka.

Ikharbhon monoxide (CO), irhasi engenavumba, engenambala. Iveliswa nanini na isibaso sefosili sitshisiwe kwaye sinokubangela ukugula kunye nokufa ngequbuliso. I-CDC isebenza nesizwe, urhulumente, wendawo, kunye namanye amaqabane ukwazisa malunga netyhefu ye-CO kunye nokubeka iliso kwi-CO enxulumene nokugula kunye nedatha yokucupha ukufa e-US.

Umsi wecuba lokusingqongileyo / umsi wecuba

Umsi wecuba ubeka ingozi kwiintsana, abantwana nakubantu abadala.

Akukho nqanaba likhuselekileyo lokuchanabeka kumsi wecuba. Abantu abangatshayiyo abachanabeke kwicuba, nokuba lixeshana nje elifutshane, banokuba nemiphumo eyingozi empilweni.1,2,3
Kubantu abadala abangatshayiyo, umsi wecuba unokubangela isifo sentliziyo, isifo sohlangothi, umhlaza wemiphunga nezinye izifo. Kwakhona kunokubangela ukufa kwangaphambi kwexesha.1,2,3
Umsi wecuba unokubangela imiphumo emibi yempilo yokuzala kwabasetyhini, kuquka ubunzima bokuzalwa obuphantsi.1,3
Ebantwaneni, ukuchanabeka komsi wecuba kunokubangela izifo zokuphefumla, usulelo lwendlebe, kunye nokuhlaselwa sisifuba. Kwiintsana, umsi wecuba unokubangela isifo sokufa komntwana ngokukhawuleza (SIDS) .1,2,3
Ukususela ngowe-1964, bamalunga nezi-2 500 000 abantu abangatshayiyo abaye babulawa ziingxaki zempilo ezibangelwa kukutshaya.1
Imiphumo yokutshatyalaliswa komsi wesibini emzimbeni ngokukhawuleza.1,3 Ukutshatyalaliswa komsi wesibini kunokuvelisa imiphumo eyingozi yokuvuvukala kunye nokuphefumula ngaphakathi kwemizuzu ye-60 enokuthi ihlale ubuncinane kwiiyure ezintathu emva kokutshatyalaliswa.4
