Asidi ya citric imatha kupanga zinthu zomwe zimathandiza kupuma bwino mu nthunzi ya e-cigarette.

Kafukufuku akufunika pakugwiritsa ntchito citric acid mu e-liquids kuti amvetsetse bwino momwe imapangira ma anhydride omwe angakhale oopsa mu nthunzi.
Citric acid imapezeka mwachilengedwe m'thupi ndipo "nthawi zambiri imadziwika kuti ndi yotetezeka" ku United States kuti igwiritsidwe ntchito mu mankhwala opumira. Komabe, kutentha kwa citric acid kumatha kuchitika kutentha kwa zipangizo zina zopumira. Pa kutentha kwa pafupifupi 175-203°C, citric acid imatha kuwola ndikupanga citraconic anhydride ndi isomeric itaconic anhydride yake.
Ma anhydride amenewa ndi zinthu zomwe zimathandiza kuti munthu azitha kupuma bwino—mankhwala omwe, akapumidwa, angayambitse ziwengo kuyambira pa zizindikiro za chimfine mpaka ku anaphylactic shock.
Asayansi a fodya aku Britain ku America adagwiritsa ntchito gasi chromatography pamodzi ndi nthawi yowuluka kuti aone nthunzi yomwe imapezeka pamene e-liquid yokhala ndi citric acid imatenthedwa mu chipangizo chopopera nthunzi. Chipangizo chomwe chinagwiritsidwa ntchito chinali ndudu yamagetsi ya m'badwo woyamba (monga ndudu). Asayansiwa adatha kuyeza kuchuluka kwa anhydride mu nthunzi.
Zotsatirazi zaperekedwa lero pamsonkhano wapachaka wa bungwe lofufuza za Nicotine and Tobacco Research Association ku Florence, Italy.
"Citric acid mu e-liquid ingayambitse kuchuluka kwa citraconia ndi/kapena itaconic anhydride mu utsi, kutengera chipangizocho," adatero Dr. Sandra Costigan, Chief Toxicologist ku Vaping Products.
"Komabe, timakhulupirira kugwiritsa ntchito bwino zokometsera ndipo tachotsa zokometsera zina muzinthu zathu." zomwe zidafufuzidwa mafuta asanayambe kugulitsidwa," adatero Costigan.
Anthu ambiri m'gulu la anthu ogwira ntchito zachipatala amakhulupirira kuti ndudu zamagetsi zimatha kuchepetsa mavuto omwe anthu amakumana nawo chifukwa cha kusuta fodya pa thanzi lawo. Bungwe la Public Health England, lomwe ndi bungwe loyang'anira dipatimenti ya zaumoyo ku UK, posachedwapa latulutsa lipoti lonena kuti kugwiritsa ntchito ndudu zamagetsi kukuyerekezeredwa kuti ndi kotetezeka ndi 95% kuposa kusuta fodya. Bungwe la Royal College of Physicians lati anthu onse akhoza kukhala ndi chidaliro kuti ndudu zamagetsi ndi zotetezeka kwambiri kuposa kusuta fodya ndipo ziyenera kulengezedwa kwambiri ngati njira ina m'malo mwa ndudu.
Ngati mwakumana ndi vuto la kulemba, kulakwitsa, kapena mukufuna kutumiza pempho loti musinthe zomwe zili patsamba lino, chonde gwiritsani ntchito fomu iyi. Pa mafunso ambiri, chonde gwiritsani ntchito fomu yathu yolumikizirana. Kuti mudziwe zambiri, chonde gwiritsani ntchito gawo la ndemanga za anthu onse pansipa (malingaliro chonde).
Ndemanga zanu ndi zofunika kwambiri kwa ife. Komabe, chifukwa cha kuchuluka kwa mauthenga, sitingatsimikizire mayankho a munthu aliyense payekha.
