Barium yog silvery-dawb, lustrous alkaline ntiaj teb hlau paub txog nws cov khoom tshwj xeeb thiab ntau yam kev siv hauv ntau yam lag luam. Barium, nrog tus lej atomic 56 thiab cim Ba, yog siv dav hauv kev tsim cov khoom sib txuas, suav nrog barium sulfate thiab barium carbonate. Txawm li cas los xij, nws yog ib qho tseem ceeb los daws cov teeb meem muaj feem cuam tshuam nrogbarium hlau.
Puas yog barium hlau txaus ntshai? Cov lus teb luv luv yog yog. Zoo li ntau lwm yam hlau hnyav, barium ua rau muaj kev pheej hmoo rau tib neeg kev noj qab haus huv thiab ib puag ncig. Txoj kev tuav, khaws cia thiab pov tseg kom raug yog tsim nyog los ua kom cov neeg ua haujlwm muaj kev nyab xeeb thiab tiv thaiv kom tsis txhob muaj kev phom sij rau cov tsiaj qus thiab ecosystems.
Ib qho kev txhawj xeeb loj ntawm cov hlau barium yog nws cov tshuaj lom. Thaum nqus tau los yog noj, nws tuaj yeem ua rau muaj ntau yam teeb meem kev noj qab haus huv, suav nrog teeb meem ua pa, plab hnyuv, cov leeg tsis muaj zog, thiab txawm tias lub plawv tsis zoo. Kev raug barium ntev tuaj yeem ua rau muaj kev hem thawj rau tib neeg kev noj qab haus huv. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum tau ua raws li cov txheej txheem kev nyab xeeb tsim thaum ua hauj lwm nrog barium los yog ib qho ntawm nws cov tebchaw.
Hais txog kev phom sij ntawm kev ua haujlwm, barium hlau tuaj yeem yog qhov kev txhawj xeeb hauv kev lag luam, tshwj xeeb tshaj yog thaum nws tsim khoom lossis kho kom zoo. Barium ores thiab cov tebchaw feem ntau pom muaj nyob hauv cov mines hauv av, thiab cov neeg ua haujlwm koom nrog hauv kev rho tawm barium thiab kev ua haujlwm yuav raug cuam tshuam rau cov hlau thiab nws cov ntsiab lus tseem ceeb. Yog li, cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) thiab cov txheej txheem kev nyab xeeb dav dav yog qhov tseem ceeb los txo qis kev pheej hmoo.
Ntxiv nrog rau kev phom sij ntawm kev ua haujlwm, kev tso tawm barium rau hauv ib puag ncig kuj tuaj yeem tsim kev puas tsuaj. Kev pov tseg tsis raug ntawm cov khoom pov tseg uas muaj barium lossis kev tso tawm ntawm cov khoom sib txuas barium tuaj yeem ua rau dej thiab av. Cov pa phem no ua rau muaj kev pheej hmoo rau cov dej thiab lwm yam kab mob hauv lub ecosystem. Yog li ntawd, nws yog ib qho tseem ceeb rau kev lag luam uas siv barium los siv cov tswv yim tswj cov khib nyiab zoo thiab ua raws li cov cai ntawm ib puag ncig.
Txhawm rau txo qhov phom sij ntawm barium, ntau yam kev ntsuas kev nyab xeeb tuaj yeem ua. Ua ntej, engineering tswj xws li cua tshuab thiab fume hoods yuav tsum tau muab tso rau hauv qhov chaw kom txo tau cov neeg ua hauj lwm raug thaum lub sij hawm tuav thiab ua.barium hlau. Tsis tas li ntawd, cov cuab yeej tiv thaiv tus kheej xws li hnab looj tes, tsom iav thiab lub tshuab ua pa yuav tsum tau muab thiab siv raws li kev tiv thaiv kev sib cuag lossis nqus pa.
Tsis tas li ntawd, cov neeg ua haujlwm yuav tsum tau muab kev cob qhia thiab kev kawm tsim nyog kom lawv paub txog cov kev pheej hmoo uas cuam tshuam nrog barium. Qhov no suav nrog kev qhia lawv txog kev coj ua kom nyab xeeb, cov txheej txheem xwm txheej ceev thiab qhov tseem ceeb ntawm kev kuaj lub cev tsis tu ncua kom paub tseeb tias muaj teeb meem kev noj qab haus huv cuam tshuam nrog barium raug.
Cov koom haum tswj hwm xws li Kev Tswj Xyuas Kev Nyab Xeeb thiab Kev Noj Qab Haus Huv (OSHA) ua lub luag haujlwm tseem ceeb hauv kev teeb tsa thiab tswj hwm cov qauv kev nyab xeeb hauv chaw ua haujlwm uas tswj cov khoom phom sij xws li barium. Yog li ntawd, nws yog ib qho tsim nyog rau kev lag luam thiab cov tswv ntiav ua haujlwm kom paub txog cov kev cai no thiab siv zog ua raws li lawv.
Hauv cov ntsiab lus, barium hlau yog qhov txaus ntshai tiag tiag thiab tuaj yeem ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv thiab ib puag ncig yog tias tsis tau ceev faj kom raug. Cov neeg ua haujlwm tuav barium thiab nws cov khoom sib txuas yuav tsum tau nruab nrog kev paub tsim nyog, kev cob qhia thiab cov cuab yeej tiv thaiv kom ntseeg tau tias lawv muaj kev nyab xeeb. Kev ua raws li cov lus qhia kev nyab xeeb thiab kev tswj hwm ib puag ncig yog qhov tseem ceeb rau kev txo qis kev phom sij cuam tshuam nrog cov hlau barium thiab tswj kom muaj kev nyab xeeb ntawm kev ua haujlwm.
