Nrog rau kev siv zog los txwv cov mos txwv txhuas uas yog qhov muaj peev xwm noj qab haus huv thiab ib puag ncig muaj kev phom sij, cov kws tshawb fawb tau tshaj tawm cov pov thawj tshiab tias cov khoom siv tseem ceeb rau cov mos txwv - tungsten - tej zaum yuav tsis yog qhov hloov tau zoo Daim ntawv tshaj tawm, uas pom tias tungsten accumulates hauv cov qauv loj ntawm Cov kab mob tiv thaiv kab mob hauv cov tsiaj, tshwm sim hauv ACS's Journal Chemical Research in Toxicology.

Nrog rau kev siv zog los txwv cov mos txwv txhuas uas yog qhov muaj peev xwm noj qab haus huv thiab ib puag ncig muaj kev phom sij, cov kws tshawb fawb tau tshaj tawm cov pov thawj tshiab tias cov khoom siv tseem ceeb rau cov mos txwv - tungsten - tej zaum yuav tsis yog qhov hloov tau zoo Daim ntawv tshaj tawm, uas pom tias tungsten accumulates hauv cov qauv loj ntawm Cov kab mob tiv thaiv kab mob hauv cov tsiaj, tshwm sim hauv ACS's Journal Chemical Research in Toxicology.

Jose Centeno thiab cov npoj yaig piav qhia tias tungsten alloys tau qhia los ua ib qho kev hloov pauv rau cov hmoov txhuas hauv cov mos txwv thiab lwm yam foob pob hluav taws. Nws tshwm sim los ntawm kev txhawj xeeb tias cov hmoov txhuas los ntawm cov mos txwv yuav ua rau cov tsiaj qus thaum nws yaj mus rau hauv dej hauv av, kwj deg, thiab pas dej. Cov kws tshawb fawb xav tias tungsten kuj tsis muaj tshuaj lom, thiab "ntsuab" hloov rau txhuas. Cov kev tshawb fawb tsis ntev los no tau tawm tswv yim txwv tsis pub, thiab nrog me me ntawm tungsten kuj tseem siv hauv qee lub duav thiab lub hauv caug, Centeno pawg txiav txim siab los sau cov ntaub ntawv ntxiv ntawm tungsten.

Lawv ntxiv me me ntawm cov tungsten compound rau cov dej haus ntawm cov nas kuaj, siv los ua surrogates rau cov neeg hauv cov kev tshawb fawb no, thiab tshuaj xyuas lub cev thiab cov ntaub so ntswg kom pom tseeb tias qhov twg tungsten xaus. Qhov siab tshaj plaws ntawm tungsten yog nyob rau hauv tus po, yog ib qho ntawm cov khoom tseem ceeb ntawm lub cev tiv thaiv kab mob, thiab cov pob txha, qhov chaw lossis "marrow" uas yog thawj qhov chaw ntawm tag nrho cov hlwb ntawm lub cev tiv thaiv kab mob. Kev tshawb fawb ntxiv, lawv hais tias, yuav tsum tau txiav txim siab seb qhov cuam tshuam dab tsi, yog tias muaj, tungsten yuav muaj rau kev ua haujlwm ntawm lub cev tiv thaiv kab mob.
