Ua kapa ʻia nā loea o ka National Laboratory ma muli o VI Lawrence ma Berkeley i ʻAmelika Hui Pū ʻIa, i ke aʻo ʻana i ka hana o ka uahi o nā uahi paka uila, ua ʻike lākou he mea ʻino ia i ke olakino kanaka e like me nā kūpaka mau.
Manaʻo kekahi poʻe puhipaka (a me nā poʻe puhipaka ʻole hoʻi) palekana nā e-hikaka no ko lākou olakino, a i ʻole ma ka liʻiliʻi ʻoi aku ka pōʻino ma mua o nā kūpaka mau. E puhi mālie ʻoe iho a mai noʻonoʻo e pili ana i kekahi mea. Akā no ka pehea. Ua paʻi ka paʻi ʻAmelika i ka ʻepekema ʻepekema a me ka ʻenehana i kahi noiʻi me nā ʻoiaʻiʻo a me nā papa kemika e hōʻike nei ʻaʻole ʻokoʻa nā e-paka i nā mea maʻamau.
"'Saylelo nā mea kākoʻo E-cigarette i ka hoʻohaʻahaʻa o nā mea hoʻopōʻino i kā lākou haku mele ʻana he ʻoi aku ka haʻahaʻa ma mua o ka puhipaka ʻana i nā kika mau. He ʻoiaʻiʻo paha kēia manaʻo no nā poʻe puhipaka ʻike hiki ʻole ke haʻalele i ka puhipaka. Akā ʻaʻole ia he manaʻo no ka makaʻu ʻole ʻo ka e-hikika. Inā ʻoi loa ka hōʻino ʻia o ka pīpaka maʻamau, a laila maikaʻi ʻole nā e-pākeke, "wahi a ka mea kākau noiʻi ʻo Hugo Destailatz o Lawrence Berkeley National Laboratory.
I mea e hoʻopaʻa ai i ka ʻāpana o ka uahi i nā e-pākeke, lawe ʻia ʻelua mau e-ʻume: he mea ʻoluʻolu me hoʻokahi wili pūwela a me kahi mea pipiʻi me ʻelua mau wili uila. Ua hoʻololi ʻia ua hoʻonui ʻia nā kemika weliweli i loko o ka uahi i nā manawa he nui i ka puff mua a me hope. Ua ʻike nui ʻia kēia i kahi uahi uahi uila.
E pili ana i nā helu, ke kiʻekiʻe o ka acleroin, ka mea e hoʻonāukiuki i nā membrane mucous o nā maka a me ka hanu hanu, i hoʻonui ʻia nā e-uahi mai 8,7 a 100 mau microgram (i nā uahi maʻamau, hiki ke pae o ka acleroin mai 450- 600 micrograms).
Pālua ka pōʻino mai ka uahi paka uila inā hoʻohana hou ia. Ua hoʻololi ʻia i ka wā e hoʻopihapiha ana i nā uahi uila, hoʻohana ʻia nā mea e like me propylene glycol a me glycerin, i ʻoi aku ma mua o 30 mau pūhui kemika weliweli, e like me ka propylene oxide a me glycidolom i ʻōlelo ʻole ʻia ma mua.
Ma ka laulā, ʻo ka hopena kēia: ʻaʻole ka puhipaka wale nō ka manawa (a no ka manawa lōʻihi!), Akā ʻino pū kekahi. E heluhelu hou aʻe e pili ana pehea e haʻalele ai i ka puhi ʻana ma aneʻi.
