Khuphukela usikilidi wake ephephile?

Ugwayi - kungcono umkhiqizo kuphela esemthethweni lapho lisetshenziswa njengedivaysi iqondiswe ibulala abantu. Ngakho ngicabanga hhayi nalabo abasebenza ukunakekelwa kwezempilo kuphela. Kwase kuphele amashumi eminyaka izwe yesayensi lithole ubufakazi obubhalwe ukulimaza lentuthu kagwayi. Siyazi ukuthi osikilidi kubangele ngaphezu izinhlobo kweshumi umdlavuza, izinkinga zenhliziyo, isifo sohlangothi, isifo yokuphefumula nezinye izifo. Kungani-ke namanje hhayi ngokusemthethweni uvinjelwe ukubhema? Ingabe zonke lezi izingozi sake bungaveli nokuthi ososayensi Ziyoza nge osikilidi kuphephile?

carcinogens noGwayi kuyingozi kakhulu

Ngakolunye uhlangothi, kunabantu abajabulela ukubhema, ngakolunye - lonke bunch of izifo ezihlukahlukene yingozi. Ngokusho umsebenzi wase-University of Minnesota uStefanu Hecht, azikho izimfanelo lokuthi esikhathini esizayo esiseduze, ososayensi ngeke benze ngendlela ephephile zokubhema. Uchwepheshe usebenza enkabeni Oncology, kodwa uhlola nomthelela emzimbeni lesiguli carcinogens ugwayi. Eqinisweni, yogwayi - cocktail eziyinkimbinkimbi ukuthi siqukethe izingxenye anamane amawaka. Ngoba konke lokhu amakhemikhali compounds of carcinogens okungenani 70 aziwa oluyingozi. Isintu ebhema i-emakhulwini amaningi eminyaka. Nokho, kuze kube manje akekho owasungula ugwayi ne wokuqukethwe esincishisiwe imikhiqizo eyingozi.

Kwengxenye yekhulu leminyaka le-Imboni kagwayi is ekuxazululeni impikiswano akusizanga

Empeleni, imboni kagwayi isebenza kanzima ukwakha osikilidi ephephile iminyaka engu-50. Naphezu iziphakamiso impikiswano ngesimo ongakhetha ukukhanya, manje kuyacaca: azikho izimfanelo for intuthuko. Kubonakala ephephile ukubhema inketho ukusesha zifinyelele kwangqingetshe. On the imizamo ukwakha usikilidi ayinangozi etshela intatheli Will Storr. Iphutha eyinhloko nomkhiqizi kugcilwa ekudaleni isihlungi ephephile. Ngeshwa, lokhu akunakwenzeka, njengoba engekho isinyathelo enkulu ekwakhekeni imikhiqizo kagwayi abakwazi ukugcina umkhiqizo carcinogens, ekuqaleni owawuqukethe emaqabungeni. Ngisho nemizamo ukusebenzisa njengendlela lemifanekiso into esindayo ezifana asbestos, wahlupheka uyisehluleki. Lapho ukufuthelana ugwayi aftertaste kwesokunxele emlonyeni wakho sulphur evutha amapulasitiki namalahle.

Buthelela carcinogens emaqabungeni ugwayi

Ezinye izidakamizwa esindayo ezitholakala ugwayi ihamba ngesikhathi sokuvuna. Ngokumangalisayo, izitshalo ukuqonda yonke izinto eziyingozi, izinsimbi kanye metalloids eziqukethwe inhlabathi, amanzi kanye nomkhathi. Ugwayi ubamba arsenic ne-cadmium kusuka umquba. Amahlamvu izitshalo babe izinwele okunamathelayo okuyinto zathathwa kusukela ezinhlayiyeni emoyeni izakhi radioactive, ezifana polonium-210.

ingqondo kwandisa ngesikhathi izigaba ezilandelayo

Ngaphezu kwalokho, lapho iphele amahlamvu ugwayi, etholakala isakhiwo sabo ikhemikhali aguqulwa ibe izakhi ethize - nitrosamines. Bese-ke, uma umuntu obhema ngokusesilinganisweni ikhanyisa ugwayi asibeke emlonyeni, evutha kagwayi igcwalisa monoxide carbon, i-hydrogen cyanide futhi wonke cocktail of carcinogens, kuhlanganise - polycyclic hydrocarbon elimnandi. Futhi emsini ugwayi kukhona izinto oluyingozi-formaldehyde futhi benzene. Ngakho, nakuba umuntu ebhema ugwayi, emaphashini akhe ezele ayingozi.

umthelela endleleni ndaba

Akusiyo imfihlo ukuthi ezinye ohlwini contact carcinogens atholakala ukudla. Noma kunjalo, ukwelashwa ukushisa ngesikhathi ukupheka kanye ukuvutshelwa e pheshana emathunjini. Futhi kuphela ke amasalela kumakhemikhali ayingozi lingene egazini. Obhemayo futhi iyavuleka kagwayi ukuthi ngqo engcolisa umzimba wakho.

Kungani izihlungi ugwayi azisebenzi?

Ezinye izinyathelo eceleni ezingase inciphise carcinogens emsini. Ngokwesibonelo, i-carbon izihlungu amunca izinto oluyingozi. Kodwa ayikho neyodwa kulezi zinyathelo ezihlongozwayo abakwazi kuthinte lonke uhlu compounds eziyingozi.

gum-nicotine

Asizange asho mayelana ne-nicotine, nomongo akuyona umdlavuza. Inkinga iwukuthi gum-nicotine kakhulu umlutha kagwayi. Ngaphezu kwalokho, yini ukwandisa izinga lokushaya kwenhliziyo, constrict imithambo yegazi kanye ukukhulisa amazinga cholesterol. Eqinisweni, i-nicotine eyenza umuntu abe isigqila futhi kwenza nsuku donsa bonke compounds eziyingozi, esixoxe kabanzi ngazo ngaphambili.

Zikhona ongakhetha ephephile?

Uma intuthu kagwayi iqukethe carcinogens kakhulu, kungani ungavezi ukuhlafuna abancela noma isinemfu kukho? Akekho izindlela owenziwa manje aqede abantu izinto ezisindayo yayinezindlu emaqabungeni ugwayi. Okuwukuphela kungase kubhekwe njengento snus, elibusa emakethe isiSwidi. Ngokusho kochwepheshe, le Scandinavians anezinga amancane kakhulu okuba nomdlavuza wamaphaphu kuqhathaniswa namazwe lapho ukubhema bendabuko luqhutshwa.

osikilidi Electronic ngemcondvo zisekhona ephephile kuka snus. Nokho, akekho owaziyo ukuthi yini obhemayo uthola ukungcola phakathi ugqozi. Kuyaziwa ukuthi ukukhiqizwa e-ugwayi is angahlelekile, okusho ukuthi lokhu okunye akanakuthenjwa. Kubonakala sengathi umphakathi sibheke mpikiswano okuphakade abanolaka.
