Poyesa kuletsa zida zokhala ndi mtovu ngati chiwopsezo cha thanzi komanso chilengedwe, asayansi akupereka umboni watsopano wosonyeza kuti chinthu china chopangira zipolopolo - tungsten - sichingakhale cholowa m'malo mwabwino. chitetezo chamthupi mwa nyama, chimapezeka m'magazini ya ACS Chemical Research in Toxicology.

Poyesa kuletsa zida zokhala ndi mtovu ngati chiwopsezo cha thanzi komanso chilengedwe, asayansi akupereka umboni watsopano wosonyeza kuti chinthu china chopangira zipolopolo - tungsten - sichingakhale cholowa m'malo mwabwino. chitetezo chamthupi mwa nyama, chimapezeka m'magazini ya ACS Chemical Research in Toxicology.

Jose Centeno ndi anzake akufotokoza kuti ma tungsten alloys adayambitsidwa kuti alowe m'malo mwa zipolopolo ndi zida zina.Zinakhalapo chifukwa chodera nkhaŵa kuti mtovu wochokera ku zida zogwiritsidwa ntchito ukhoza kuvulaza nyama zakuthengo ukasungunuka m’madzi m’nthaka, m’mitsinje, ndi m’nyanja.Asayansi ankaganiza kuti tungsten inali yopanda poizoni, komanso "yobiriwira" m'malo mwa lead.Kafukufuku waposachedwa sananene kuti, ndipo ndi tungsten yaying'ono yomwe imagwiritsidwanso ntchito m'chiuno ndi mawondo ochita kupanga, gulu la Centeno linaganiza zosonkhanitsa zambiri za tungsten.

Iwo anawonjezera kachulukidwe kakang'ono ka tungsten m'madzi akumwa a mbewa za labotale, omwe amagwiritsidwa ntchito ngati malo opangira anthu ochita kafukufuku wotero, ndikuwunika ziwalo ndi minyewa kuti awone komwe tungsten adathera.Zomwe zimakhala zapamwamba kwambiri za tungsten zinali mu ndulu, chimodzi mwa zigawo zikuluzikulu za chitetezo cha mthupi, ndi mafupa, pakati kapena "mafuta" omwe ali gwero loyamba la maselo onse a chitetezo cha mthupi.Kafukufuku wowonjezereka, akuti, adzafunika kuti adziwe zomwe, ngati zilipo, tungsten angakhale nazo pakugwira ntchito kwa chitetezo chamthupi.
