Cov siv lead ua tshiab tso cai rau cov neeg dhia dej nyob hauv qab dej tau ntau teev

Puas tau xav ua pa hauv qab dej? Tej zaum koj yuav muaj peev xwm nyob rau yav tom ntej.

Cov kws tshawb fawb ntawm University of Southern Denmark tau tsim "cov khoom siv crystalline uas tuaj yeem khi thiab khaws cov pa oxygen hauv cov ntsiab lus siab" raws li mic. Sib nrug los ntawm qhov ua tau los ntawm kev ua pa hauv qab dej, cov khoom siv lead ua no tuaj yeem siv los ntawm cov pa oxygen tso tsheb hlau luam rau tib neeg, kev lag luam, thiab txawm tias tsheb ua qhov chaw roj. Cov crystals no ua raws li ob qho tib si sensor thiab lub thawv rau oxygen molecules; lawv khi, khaws cia, thiab thauj cov pa oxygen hauv lawv cov qauv.

Cov crystals ua haujlwm los ntawm lawv cov qauv molecular thiab hluav taws xob tshwj xeeb. Cobalt yog siv rau hauv cov khoom siv thiab cov txiaj ntsig molecular thiab cov qauv hluav taws xob ua rau nws muaj kev sib raug zoo rau cov pa oxygen uas tso cai rau nws nkag tau yooj yim absorbed thiab sib txuas nrog cov siv lead ua.
