Ua ntej, muaj cov lus ceeb toom tias muaj teeb meem lead-ntau tshaj hauv faucets, uas yuav ua rau muaj kev phom sij rau tib neeg lub cev. Nyob rau lub Tsib Hlis xyoo no, tus qauv tshiab ntawm lub teb chaws tus qauv rau faucets tau raug tso tawm thiab yuav raug siv los ntawm lub hli tom ntej. Lub teb chaws tus qauv tshiab qhia txog qhov txwv rau nag lossis daus.
Nag hmo, Lub Chaw Saib Xyuas Kev Ua Haujlwm Zoo ntawm Jiangsu Xeev tau ua qhov chaw kuaj xyuas thiab saib xyuas kev pheej hmoo ntawm cov kais dej hauv Jiangsu kev ua lag luam thiab cov chaw tsim khoom raws li cov qauv hauv tebchaws tam sim no thiab cov qauv tshiab hauv tebchaws.. Raws li qhov tshwm sim, 20% ntawm cov hlau lead nag lossis daus ntawm tooj liab alloy kais dej tshaj qhov txwv ntawm lub teb chaws tus qauv tshiab.
Cov hlau lead thiab chromium ntau dhau
Pib lub Kaum Ob Hlis, kev tsim cov khoom ntau tshaj li tus qauv yuav raug rau txim
yav dhau los, tsis muaj qhov yuav tsum tau txwv rau qhov muaj kuab paug los nag hauv faucets. Lub teb chaws tus qauv tshiab yuav kos cov txheej txheem tshawb nrhiav thiab txwv cov qauv hauv Tebchaws Meskas.
