Lub tshuab ntsuas roj sib xyaw ua haujlwm li cas?
Nws muaj qhov sib txawv ntawm kev tshawb nrhiav cov pa roj carbon monoxide thiab lwm yam roj, thiab peb yuav tsum tau ua tib zoo saib xyuas cov lus qhia rau kev tshawb nrhiav cov pa phem hauv kev tshawb nrhiav roj. Yog tias peb tsis xyuam xim thaum lub sijhawm kuaj pom, tej zaum yuav muaj qee qhov teeb meem lom. Yog tias muaj cov tsos mob lom thaum siv, nws raug nquahu kom nrhiav kev kho mob tam sim ntawd. Hauv qab no yog ib qho kev piav qhia ntawm qee qhov kev ua haujlwm lom cov paib uas yuav tshwm sim thaum lub sijhawm tshawb nrhiav cov khoom siv hluav taws xob sib xyaw!
(1) Kev ua haujlwm lom neeg tuaj yeem tshwm sim los ntawm kev tsim cov co toxins. Kev ua haujlwm lom neeg tuaj yeem muab faib ua peb hom raws li cov txheej txheem pib. Mob hnyav: tshwm sim los ntawm ntau cov tshuaj lom neeg nkag mus rau tib neeg lub cev hauv ib lossis ib lub sijhawm luv luv. Feem ntau ntawm lawv yog tshwm sim los ntawm kev tsim khoom raug tsim txom lossis ua txhaum txoj haujlwm ua haujlwm. Chronic poisoning : Chronic poisoning yog hais txog kev nkag mus ntev ntawm cov co toxins me me rau hauv lub cev. Feem ntau yog tshwm sim los ntawm cov co toxins. Subacute lom: Subacute lom yog ib qho tshwm sim lom uas tshwm sim thaum muaj ntau cov tshuaj lom neeg nkag mus rau tib neeg lub cev hauv lub sijhawm luv luv, thiab poob ntawm ob.
(2) Tiv tauj nrog cov co toxins hauv lub xeev muaj tshuaj lom, tab sis tsis muaj cov tsos mob lom lossis cov tsos mob ntawm lub cev. Tus nqi ntawm cov co toxins (los yog cov metabolites) muaj nyob rau hauv cov zis los yog lwm yam khoom siv lom neeg muaj ntau tshaj li qhov siab tshaj ntawm cov nqi ib txwm muaj; Los yog qhov zoo rau qhov kev ntsuam xyuas qhov chaw hloov chaw (xws li cov hlau lead thiab mercury hloov chaw). Lub xeev no hu ua toxic state los yog tshuaj lom neeg nqus lub xeev, xws li lead absorption.
(3) Lwm yam kev ua haujlwm xws li beryllium tuaj yeem ua rau mob ntsws beryllium; Fluoride tuaj yeem ua rau pob txha fluorosis; Vinyl chloride tuaj yeem ua rau osteolysis; Tar asphalt tuaj yeem ua rau cov kab mob ntawm daim tawv nqaij xws li melanosis.
(4) Mutagenic, carcinogenic, thiab teratogenic qee yam tshuaj lom neeg tuaj yeem ua rau muaj kev hloov pauv hauv lub cev. Cov tshuaj uas muaj cov nyhuv mutagenic hu ua tshuaj mutagens. Qee cov tshuaj lom neeg tuaj yeem ua rau mob qog noj ntshav, thiab cov tshuaj uas tuaj yeem ua rau mob qog noj ntshav hauv tib neeg lossis tsiaj yog hu ua carcinogens. Qee cov tshuaj lom neeg muaj tshuaj lom rau ntawm embryos thiab tuaj yeem ua rau deformities, thiab cov tshuaj no hu ua teratogens.
(5) Kev cuam tshuam ntawm kev lag luam co toxins ntawm kev ua me nyuam muaj peev xwm cuam tshuam rau kev coj khaub ncaws, cev xeeb tub, lactation, thiab lwm yam kev ua me nyuam ntawm cov poj niam ua haujlwm. Nws tsis tsuas yog tsim kev puas tsuaj rau cov poj niam lawv tus kheej xwb, tab sis kuj tuaj yeem cuam tshuam rau lwm tiam neeg. Cov poj niam cov neeg ua haujlwm uas tuaj rau hauv kev sib cuag nrog benzene thiab nws cov homologues, roj av, carbon disulfide, thiab trinitrotoluene yog qhov ua rau mob khaub thuas; Cov poj niam cov neeg ua haujlwm uas tau ntsib nrog cov hlau lead, mercury, thiab trichlorethylene yog qhov ua rau muaj tus mob oligomenorrhea. Cov tshuaj mutagens tuaj yeem ua rau muaj kev hloov pauv hauv cov kab mob, ua rau teratogens, tshwj xeeb tshaj yog nyob rau thawj peb lub hlis ntawm cev xeeb tub thaum embryos rhiab heev rau cov tshuaj lom neeg. Thaum lub sij hawm embryonic txoj kev loj hlob, tej yam tshuaj co toxins tuaj yeem ua rau ncua sij hawm fetal ntau lawm, malformations ntawm embryonic kab mob los yog systems, thiab tuag los yog nqus ntawm fertilized qe. Ob leeg organomercury thiab polychlorinated biphenyls muaj cov teebmeem teratogenic. Cov txiv neej cov neeg ua haujlwm uas tuaj rau hauv kev sib cuag nrog carbon disulfide yog cov txawj suav, uas tuaj yeem txo qis fertility; Lead thiab dibromochloropropane kuj muaj kev cuam tshuam rau txiv neej fertility. Lead, mercury, arsenic, carbon disulfide, thiab lwm yam khoom tuaj yeem nkag mus rau hauv lub cev ntawm cov menyuam mos los ntawm cov mis nyuj, cuam tshuam rau kev noj qab haus huv ntawm lwm tiam neeg.
