Yog lanthhanum oxide toxic?

Lanthhanum oxide, nrog cov mis nyuj la2o3 thiab CAS naj npawb 1312-8, yog qhov sib txuas uas tau nyiam ua kom zoo nkauj vim nws ntau yam kev siv hauv ntau yam lag luam. Txawm li cas los xij, kev txhawj xeeb txog nws cov tshuaj lom neeg muaj peev xwm tau txais kev soj ntsuam kom ze rau nws txoj kev nyab xeeb.

Lanthhanum oxideFeem ntau siv hauv kev tsim cov khoom siv kho qhov muag thiab hauv cov tsim cov khoom siv hluav taws xob ceramic thiab lwm yam hluav taws xob. Nws cov khoom tshwj xeeb, xws li cov khoom siv siab tshiab thiab tsis muaj txiaj ntsig zoo, ua rau nws muaj txiaj ntsig zoo hauv cov ntsiab muag thiab cov khoom siv kho qhov muag. Ib qho ntxiv, nws yog siv los ua catalyst nyob rau hauv kev lag luam roj av thiab raws li ib feem ntawm kev tsim cov alloys tshwj xeeb.

Txawm hais tias Lanthhanum oxide yog siv dav siv, cov lus nug nyob twj ywm txog nws cov peev xwm lom zem. Cov kev tshawb fawb tau ua los ntsuas nws cov teebmeem rau tib neeg kev noj qab haus huv thiab ib puag ncig. Nws yog ib qho tseem ceeb kom nco ntsoov tias thaum lub suab paj nruag oxide nws tus kheej tsis tau txiav txim siab heev, qee yam kev ceev faj yuav tsum tau coj los txo cov peev xwm tsawg.

Inhalation ntawmLanthhanum oxideCov hmoov av lossis cov pa ncho yuav tsum zam ib yam li nws yuav ua pa ua pa. Qhov chaw tso pa kom zoo thiab kev siv cov khoom tiv thaiv tus kheej, xws li lub npog ntsej muag, raug pom zoo thaum daws cov hmoov lossis aerosol daim ntawv. Daim tawv sib chwv nrog cov kab mob Lanthhan ib sab yuav tsum tau txo qis thiab tej yam nchuav thiab tej yam nchuav thiab tej yam nchuav khoom yuav tsum raug ntxuav kom tiv thaiv cov peev xwm tiv thaiv cov peev xwm.

Nyob rau hauv cov nqe lus ntawm ib puag ncig kev cuam tshuam, kev pov tseg ntawm cov neeg Lanthhanb oxide yuav tsum tau tswj hwm raws li kev cai los tiv thaiv kom tsis txhob muaj cov av thiab cov dej. Txawm hais tias nws tsis raug cais raws li cov khoom siv phom sij, lub luag haujlwm tuav thiab pov tseg kev coj ua yog qhov kev pheej hmoo yuav muaj kev phom sij rau ib puag ncig.

Nws yog ib qho tseem ceeb rau cov tib neeg ua haujlwm nrogLanthhanum oxideTxhawm rau kom nkag siab nws cov khoom thiab ua raws cov lus qhia kev nyab xeeb kom txo tau ib qho kev noj qab haus huv lossis ib puag ncig ib puag ncig. Cov tswv ntiav haujlwm yuav tsum muab cov kev cob qhia thiab cov ntaub ntawv kev nyab xeeb ntawm cov compound no kom ntseeg tau tias cov neeg ua haujlwm zoo thiab ib puag ncig ib puag ncig.

Hauv cov ntsiab lus, txawm hais tiasLanthhanum oxideyog qhov muaj txiaj ntsig zoo nrog ntau cov ntawv thov kev lag luam, nws yuav tsum tau siv nrog kev ceev faj thiab paub txog ntawm cov kev pheej hmoo txaus ntshai. Cov kev tiv thaiv muaj peev xwm tuaj yeem muaj peev xwm txo tau los ntawm kev ua raws li kev nyab xeeb kev nyab xeeb thiab cov txheej txheem daws teeb meem. Cov kev tshawb fawb txuas ntxiv thiab kev soj ntsuam ntawm lawv kev noj qab haus huv thiab ib puag ncig cuam tshuam yuav pab kom nkag siab zoo dua lawv cov tswv yim kev nyab xeeb thiab tsim kev tswj hwm kev nyab xeeb.
