Zoo Siab

• 1. Yuav ua li cas kom tsis txhob tiv tauj nrog Mercury
• 2. Yuav ua li cas kom tsis txhob tiv tauj nrog Arsenic
• 3. Ua li cas kom tsis txhob tiv tauj nrog Lead
• Lwm cov hlau hnyav

Txhawm rau kom zam hnyav hlau hnyav, uas tuaj yeem ua rau muaj kev mob loj dua xws li lub raum tsis ua haujlwm lossis mob qog nqaij hlav, piv txwv, nws tseem ceeb heev kom txo qis kev sib cuag nrog txhua hom hlau hnyav ua rau muaj kev noj qab haus huv.

Mercury, arsenic thiab taug txhuas yog cov hom uas siv ntau tshaj plaws ntawm cov khoom sib txawv ntawm peb lub neej nyob niaj hnub, xws li lub teeb txawb, pleev xim thiab txawm tias khoom noj thiab, yog li ntawd, yog cov uas tuaj yeem yooj yim ua rau lom.

Pom cov tsos mob tseem ceeb ntawm kev sib kis hlau hnyav.

Txhawm rau zam tag nrho cov kev txaus ntshai ntawm kev noj qab haus huv nws yog qhov tseem ceeb kom paub tias cov khoom twg muaj ntau cov hlau no txhawm rau kom paub dab tsi hloov los yog tshem tawm ntawm kev sib cuag txhua hnub:

1. Yuav ua li cas kom tsis txhob tiv tauj nrog Mercury

Qee txoj hauv kev kom zam dhau qhov tsis tseem ceeb ntawm mercury suav nrog:

• Tsis txhob noj ntses nrog ntau cov mercury ntau, piv txwv li mackerel, swordfish lossis marlin, piv txwv li, muab kev nyiam rau cov ntses liab, sardines lossis anchovies;
• Tsis muaj khoom nrog mercury nyob hauv tsev nyob rau hauv nws cov muaj pes tsawg leeg, xws li cov xim pleev xim, cov roj teeb uas siv, cov siv hluav taws xob lossis cov ntsuas kub muaj mercury;
• Zam txhob muab cov khoom tawg nrog cov kua mercury, xws li cov teeb roj fluorescent lossis cov pas ntsuas kub;

Ntxiv rau, yog tias muaj kab noj hniav thiab lwm yam kev kho hniav, nws tseem raug nquahu kom tsis txhob siv cov tshuaj txhuam hniav nrog mercury, muab kev nyiam ua rau cov roj ua puv, piv txwv.

2. Yuav ua li cas kom tsis txhob tiv tauj nrog Arsenic

Txhawm rau zam kom dhau arsenic, nws yog ib qho tseem ceeb rau:

• Tshem tawm cov ntoo kho nrog tshuaj tiv thaiv nrog CCA lossis ACZA lossis siv ib lub tsho tiv thaiv ntawm cov xim foob lossis cov xim tsis muaj arsenic kom txo tau kev sib cuag;
• Tsis txhob siv cov tshuaj tua kab los yog tshuaj tua kab nrog monosodium methanearsonate (MSMA), calcium methanearsonate lossis cacodylic acid;
• Tsis txhob noj tshuaj nrog arsenic, nug tus kws kho mob txog tshuaj muaj pes tsawg leeg ntawm cov tshuaj nws tau siv;
• Khaws cov dej huv kom huv thiab kuaj los ntawm lub tuam txhab saib xyuas dej thiab dej phwj hauv thaj av.

Yog li, nws yog ib qho tseem ceeb kom paub txog cov lus sib xyaw ntawm txhua yam khoom ua ntej kev yuav khoom vim hais tias arsenic yog tam sim no nyob rau hauv qhov muaj pes tsawg leeg ntawm ntau cov khoom siv hauv tsev, feem ntau yog tshuaj lom neeg thiab cov khoom siv kho nrog tshuaj.

3. Ua li cas kom tsis txhob tiv tauj nrog Lead

Lead yog hlau uas muaj nyob hauv ntau yam khoom siv hauv lub neej txhua hnub thiab, yog li ntawd, nws raug nquahu kom kuaj xyuas cov khoom sib xyaw ua ntej yuav khoom, tshwj xeeb tshaj yog cov uas ua los ntawm PVC.

Ib qho ntxiv, cov hlau lead tseem yog cov hlau hnyav hnyav feem ntau siv hauv kev tsim cov xim pleev xim rau phab ntsa thiab yog li ntawd, cov tsev tsim ua ntej 1980 tej zaum yuav muaj cov hmoov txhuas ntau nyob hauv lawv cov phab ntsa. Yog li, nws raug nquahu kom tshem tawm cov xim no thiab pleev xim rau lub tsev nrog cov xim tshiab kom tsis pub muaj hlau hnyav.

Lwm qhov tseem ceeb tshaj plaws kom tsis txhob muaj cov hmoov txhuas yog kom tsis txhob siv cov kais dej tam sim tom qab qhib tus kais, thiab cia cov dej txias mus rau qhov txias tshaj plaws ua ntej haus lossis siv dej ua noj.

Lwm cov hlau hnyav

Txawm hais tias cov no yog cov hlau nyhav tshaj plaws hauv cov haujlwm txhua hnub, nws yog ib qho tseem ceeb kom tsis txhob sib cuag nrog lwm yam ntawm cov hlau hnyav, xws li barium, cadmium lossis chromium, uas nquag siv ntau dua hauv kev lag luam thiab chaw tsim kho, tab sis uas tuaj yeem ua rau muaj kev noj qab haus huv loj thaum tsim kev ntsuas kev ruaj ntseg zoo tsis siv.

Kev sib kis tau tshwm sim vim tias, txawm hais tias, tom qab sib cuag nrog feem ntau ntawm cov hlau no, tsis muaj kev txhim kho cov tsos mob, cov tshuaj no nthuav tawm hauv tib neeg lub cev, thiab tuaj yeem ua rau lub sijhawm muaj tshuaj lom nrog rau cov kev mob nyhav, xws li lub raum tsis ua haujlwm thiab. mob cancer.

Pom ib txoj kev ua kom ntuj tshem tau qee qhov kev hnyav tshaj hauv lub cev.
