Ngamaphi amaphesenti e-Cancer Cancer eyenziwa yi-Air Pollution?
Sekuyisikhathi eside kusolwa ukuthi ukungcola komoya kungabangela umdlavuza wamaphaphu . Ucwaningo lwemikhakha ehlukene engozini yomdlavuza wamaphaphu lwembula ukuthi umdlavuza wamaphaphu uvame kakhulu ezindaweni zasemadolobheni futhi awuvamile ezindaweni zasemaphandleni. Noma kunjalo, akuqinisekanga ukuthi ukungcoliswa komoya kungenxa yecala noma ezinye izinto ezihluka phakathi kwabantu abahlala ezindaweni zasemadolobheni nasemaphandleni.
Okushiwo Ucwaningo
Uma kukhona umbuzo, kungasiza ukubuka isayensi ngemuva kweyombono. Ucwaningo luye lwabonisa ukuthi ukungcola komoya kungabangela "ukucindezeleka okwenziwe nge-oxidative," okungukuthi, ukulimala kwamaseli omzimba obangelwa yi-oxydation. Lokhu, nakho, kungaholela ekuthuthukiseni umdlavuza.
Izifundo e-United States, e-Europe nase-Asia ziye zaphakamisa ukuthi ukungcoliswa komoya okuvela emotweni kanye nokushisa kwamalahle, ugesi wamafutha kanye nokukhuni, kunobungozi obuncane nomdlavuza wamaphaphu. Esifundweni se-2009 sase-US, kwacatshangwa ukuthi ama-5% wamadayamane emaphaphu wesilisa namaphesenti angu-3 wamanqamu emaphaphu phakathi kwabesifazane phakathi kuka-1970 no-1994 ayehlobene nokungcola komoya. Ucwaningo oluthile olubheka ukungcoliswa komoya emadolobheni eYurophu lukhombisa ukuthi ingozi ingase ibe ngaphezulu, futhi kufike ku-10.7% wamacala omdlavuza wamaphaphu acatshangelwa ukuthi ahlobene nokuchayeka ukungcoliswa komoya.
Ngaphandle kokufaka isandla engozini yomdlavuza wamaphaphu, isifundo se-2016 sathola ukuthi ukungcoliswa komoya kunganciphisa nokuphila phakathi kwalabo abanomdlavuza wamaphaphu.
Umthelela wokungcola komoya ekusindeni kwavame kakhulu phakathi kwalabo abanamdlavuza emaphashini asencane nalabo abane-lung adenocarcinoma.
