Hauv peb lub neej txhua hnub, daim ntawv so tes yog ib yam khoom tseem ceeb uas peb yuav tsum siv, feem ntau siv yam tsis xav ntau. Txawm li cas los xij, kev xaiv cov phuam ntawv tuaj yeem cuam tshuam rau peb txoj kev noj qab haus huv thiab ib puag ncig. Txawm hais tias kev xaiv cov phuam ntawv pheej yig zoo li yog ib qho kev daws teeb meem pheej yig, tab sis peb yuav tsum tsis txhob saib tsis taus qhov txaus ntshai ntawm kev noj qab haus huv uas cuam tshuam nrog lawv.
Cov ntawv ceeb toom tsis ntev los no, suav nrog ib qho los ntawm Science and Technology Daily hauv xyoo 2023, tau hais txog cov kev tshawb pom txaus ntshai txog cov tshuaj lom hauv daim ntawv so quav thoob ntiaj teb. Cov tshuaj xws li per- thiab polyfluoroalkyl substances (PFAS) tau txuas nrog ntau yam teeb meem kev noj qab haus huv, suav nrog kev pheej hmoo ntawm kev mob qog noj ntshav xws li mob qog noj ntshav ntsws thiab mob qog noj ntshav hauv plab hnyuv, nrog rau kev txo qis 40% ntawm cov poj niam muaj menyuam. Cov kev tshawb pom no qhia txog qhov tseem ceeb ntawm kev tshuaj xyuas cov khoom xyaw thiab cov khoom siv raw siv hauv cov khoom ntawv.
Thaum xaiv cov phuam ntawv, cov neeg siv khoom yuav tsum xav txog cov khoom siv raw uas siv. Cov kev xaiv feem ntau suav nrog cov ntoo pulp, cov ntoo pulp, thiab cov xyoob pulp. Cov ntoo pulp, uas tau los ntawm cov ntoo, muaj cov fibers ntev thiab muaj zog, tab sis nws cov khoom tsim tawm feem ntau ua rau kev rhuav tshem hav zoov, ua rau puas tsuaj rau qhov sib npaug ntawm ecological. Cov ntoo pulp, thaum ua tiav thiab kho, feem ntau muaj cov tshuaj dawb uas tuaj yeem ua rau cov dej tsis huv yog tias tsis tswj hwm kom zoo.
Nyob rau hauv kev sib piv, xyoob pulp tshwm sim ua lwm txoj hauv kev zoo dua. Xyoob loj hlob sai thiab laus sai, ua rau nws yog ib qho khoom siv ruaj khov uas txo qhov kev vam khom rau hav zoov. Los ntawm kev xaiv cov ntaub xyoob, cov neeg siv khoom tsis yog tsuas yog xaiv cov khoom noj khoom haus zoo dua uas tsis muaj cov khoom siv tsis zoo xwb tab sis kuj pab txhawb rau kev txuag ib puag ncig.
Xaus lus, thaum yuav cov phuam ntawv, nws yog ib qho tseem ceeb uas yuav tsum saib dhau tus nqi. Kev xaiv cov ntaub so ntswg xyoob tsis yog tsuas yog txhawb nqa kev noj qab haus huv ntawm tus kheej los ntawm kev zam cov tshuaj lom xwb tab sis kuj txhawb nqa lub neej yav tom ntej uas ruaj khov thiab zoo rau ib puag ncig. Hloov mus rau cov phuam ntawv noj qab haus huv hnub no thiab tiv thaiv koj txoj kev noj qab haus huv thiab lub ntiaj teb.
