Ngaba ukuvumba kwecuba ze-elektroniki kubalwa njengecuba lecuba?

Uphando kwi-nitrosamines ngokungathandabuzekiyo yeyona nto ibaluleke kakhulu kwizifundo ezininzi.Ngokoluhlu lweWorld Health Organisation lwe-carcinogens, i-nitrosamines yeyona nto iphambili ye-carcinogenic carcinogen.Umsi wecuba uqulethe inani elikhulu le-nitrosamines ethile yecuba (TSNA), efana ne-NNK, NNN, NAB, NAT… Phakathi kwabo, i-NNK kunye ne-NNN zichongwe yi-WHO njengezinto ezinamandla ezibangela umhlaza wemiphunga, ezizezona ziphambili ze-carcinogens. yecuba kunye nobungozi bokutshaya icuba.“Umoni”.

Ngaba umsi we-e-cigarette une-nitrosamines ethe ngqo yecuba?Ekuphenduleni le ngxaki, kwi-2014, uDkt Goniewicz wakhetha iimveliso ze-e-cigarette ezithengiswa kakhulu kwi-12 kwimarike ngexesha lokukhangela umsi.Iziphumo zovavanyo zibonisa ukuba umsi weemveliso zemidiza ye-elektroniki (kufuneka ibe sigarethi se-elektroniki sesizukulwana sesithathu esivulekileyo) ine nitrosamines.

Kuyafaneleka ukuba uqaphele ukuba umxholo we-nitrosamines kumsi we-e-cigarette uphantsi kakhulu kunomsi wecuba.Idatha ibonisa ukuba umxholo we-NNN kumsi we-e-cigarette ngu-1/380 kuphela we-NNN umxholo womsi we-cigarette, kwaye umxholo we-NNK ngu-1/40 kuphela we-NNK umxholo womsi we-cigarette."Olu phononongo lusixelela ukuba ukuba abantu abatshayayo batshintshela kwi-e-cigarettes, banokunciphisa ukungeniswa kwezinto ezinobungozi ezinxulumene ne-cigarette."UGqr. Goniewicz wabhala kwelo phepha.

NgoJulayi 2020, amaZiko aseMelika oLawulo lweSifo kunye noThintelo akhuphe uxwebhu oluchaza ukuba inqanaba le-nitrosamine metabolite NNAL kumchamo wabasebenzisi be-e-cigarette liphantsi kakhulu, elifana nenqanaba le-NNAL kumchamo wabantu abangatshayiyo. .Oku akukona nje ukubonakalisa impembelelo ebalulekileyo yokunciphisa umonakalo we-e-cigarettes ngesiseko sophando lukaDkt Goniewicz, kodwa kwakhona kubonisa ukuba iimveliso eziqhelekileyo ze-e-cigarette zangoku azinayo ingxaki yomsi we-second hand kwi-cigarettes.

Uphononongo lwathatha iminyaka eyi-7 kwaye lwaqala ukuqokelela idatha ye-epidemiological malunga nokuziphatha kokusetyenziswa kwecuba kwi-2013, kubandakanywa iipatheni zokusetyenziswa, izimo zengqondo, imikhwa, kunye nemiphumo yempilo.I-NNAL yimetabolite eveliswa ngumzimba womntu olungisa ii-nitrosamines.Abantu baphefumlela i-nitrosamines ngokusebenzisa iimveliso zecuba okanye umsi wecuba, baze bakhuphe i-metabolite NNAL ngomchamo.

Iziphumo zophononongo zibonisa ukuba i-avareji yoxinaniso lwe-NNAL kumchamo wabantu abatshayayo yi-285.4 ng/g creatinine, kunye ne-avareji yoxinzelelo lwe-NNAL kumchamo wabasebenzisi be-e-cigarette yi-6.3 ng/g creatinine, oko kukuthi, umxholo. ye-NNAL kumchamo wabasebenzisi be-e-cigarette kuphela ngabatshayayo yi-2.2% yetotali.
