Phenolyog ib hom organic compound, tseem hu ua carbolic acid.Nws yog xim tsis muaj xim lossis dawb crystalline khoom nrog cov ntxhiab tsw muaj zog.Nws yog tsuas yog siv rau hauv kev tsim cov dyes, pigments, adhesives, plasticizers, lubricants, tshuaj tua kab mob, thiab lwm yam. Tsis tas li ntawd, nws kuj yog ib qho tseem ceeb ntawm cov khoom nruab nrab hauv kev lag luam tshuaj.

Phenol

 

Thaum pib ntawm lub xyoo pua 20th, phenol tau pom tias muaj zog toxicity rau tib neeg lub cev, thiab nws siv nyob rau hauv zus tau tej cov tshuaj tua kab mob thiab lwm yam khoom yog maj hloov los ntawm lwm yam tshuaj.Xyoo 1930s, kev siv phenol hauv cov tshuaj pleev ib ce thiab cov khoom siv hauv chav dej raug txwv vim nws cov tshuaj toxicity thiab khaus khaus.Xyoo 1970s, kev siv phenol nyob rau hauv feem ntau cov ntawv thov kev lag luam kuj raug txwv vim nws qhov hnyav ib puag ncig thiab muaj kev phom sij rau tib neeg.

 

Hauv Tebchaws Meskas, kev siv phenol hauv kev lag luam tau tswj hwm nruj txij li xyoo 1970s.Lub Koom Haum Saib Xyuas Kev Tiv Thaiv Ib puag ncig hauv Teb Chaws Asmeskas (EPA) tau tsim ntau txoj cai lij choj thiab cov cai txwv tsis pub siv thiab emission ntawm phenol txhawm rau tiv thaiv tib neeg kev noj qab haus huv thiab ib puag ncig.Piv txwv li, cov qauv emissions rau phenol hauv cov dej khib nyiab tau raug txiav txim siab nruj, thiab kev siv phenol hauv cov txheej txheem ntau lawm tau txwv.Tsis tas li ntawd, FDA (Food and Drug Administration) kuj tau tsim ntau txoj cai los xyuas kom meej tias cov khoom noj khoom haus thiab tshuaj pleev ib ce tsis muaj phenol lossis nws cov derivatives.

 

Hauv kev xaus, txawm hais tias phenol muaj ntau yam kev siv hauv kev lag luam thiab lub neej txhua hnub, nws cov tshuaj lom thiab tsw ntxhiab tsw tau ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv thiab ib puag ncig.Yog li ntawd, ntau lub teb chaws tau ntsuas los txwv nws txoj kev siv thiab emission.Hauv Tebchaws Meskas, txawm hais tias kev siv phenol hauv kev lag luam tau raug tswj xyuas nruj, nws tseem siv dav hauv tsev kho mob thiab lwm lub tsev kho mob ua tshuaj tua kab mob thiab ua kom tsis muaj menyuam.Txawm li cas los xij, vim nws muaj toxicity siab thiab muaj peev xwm ua rau muaj kev phom sij rau kev noj qab haus huv, nws tau pom zoo tias tib neeg yuav tsum tsis txhob sib cuag nrog phenol ntau li ntau tau.
