Asbestos yog tsim los ntawm cov fibers zoo heev uas tuaj yeem woven thiab o. Elastic, resistant rau Frost thiab kub kub, rau acids thiab lwm yam caustic tshuaj, nws yog zoo tagnrho rau zus tau tej cov hluav taws-resistant fabrics (piv txwv li, khaub ncaws rau cov tua hluav taws), nres linings, sealing cords. Asbestos yog ib pab pawg ntawm cov pob zeb tsim cov pob zeb hauv cov xwm txheej thiab paub txog ntau txhiab xyoo. Tab sis tsuas yog me ntsis tshaj li ib puas xyoo dhau los, thaum lub sij hawm ntawm kev lag luam kiv puag ncig, nws tau ua ib txoj hauj lwm tiag tiag. Hmoov tsis! Nws tau paub txog li ib lub hlis twg ntawm ib puas xyoo uas cov khoom siv raw no, muaj txiaj ntsig zoo rau kev tsim khoom ntawm li 3 yam khoom, yog carcinogenic.
Hauv tebchaws Poland, nws yog siv hauv kev tsim kho, suav nrog vaj tse. Nyob rau hauv lub 60s thiab 70s, corrugated asbestos-cement boards (asbestos-cement boards (asbestos) rau sheathing ib leeg-tsev neeg thiab outbuildings, nrog rau cov insulating boards siv rau sheathing thaiv phab ntsa, tau tshwj xeeb muaj koob meej vim hais tias lawv yog pheej yig.
Yog li ntawd, thaum pib ntawm lub xyoo pua 15,5st, muaj txog 14,9 lab tons ntawm asbestos-muaj cov khoom nyob rau hauv peb lub teb chaws, suav nrog txog 600 lab tons ntawm asbestos-cement slabs, 160 tons. tons ntawm cov kav dej thiab 30 txhiab tons ntawm lwm cov khoom lag luam asbestos-cement. Qhov teeb meem loj tshaj plaws yog cov khoom lag luam uas nws lub neej kev ua haujlwm, kwv yees li XNUMX xyoo, tab tom yuav xaus. Cov no suav nrog cov vuas asbestos, feem ntau tsis saib xyuas thiab tsis pleev xim.
Asbestos cov khoom yuav tsum tsis txhob (lossis txawm raug tso cai) kom tshem tawm ntawm koj tus kheej. Tej zaum koj yuav tsis nthuav tawm koj ib puag ncig, suav nrog lwm tus neeg, lossis koj tus kheej kom muaj kab mob asbestos thiab poob kev noj qab haus huv. Cov phiaj tsuas tuaj yeem tiv thaiv los ntawm kev pleev xim rau lawv.
Cov phaj tawg, tawg ua rau muaj kev phom sij loj tshaj plaws. Lub koom haum tshawb fawb kev tsim kho tau suav tias los ntawm 1 m2 qhov chaw puas tuaj yeem tso tawm txawm tias ntau txhiab asbestos fibers.
Muaj ntau ntau yam ntawm lawv, tab sis qhov txaus ntshai tshaj plaws yog cov pa ua pa, uas yog, cov uas tas li nyob hauv huab cua thiab nkag mus rau hauv txoj hlab pa. Lawv nkag mus rau hauv alveoli, uas lawv tsis tuaj yeem raug tshem tawm. Qhov teeb meem tseem ceeb ntawm asbestos yog nyob rau hauv nws cov nyhuv irritating, ua rau asbestosis (asbestosis), mob ntsws cancer, mesothelioma ntawm lub pleura thiab peritoneum.
Ib txoj kev tshawb fawb loj ntawm qhov tshwm sim ntawm hom mob qog noj ntshav no tau pom tias muaj qhov tshwm sim ntau ntxiv ntawm cov kab mob tau pom nyob rau hauv thaj tsam ntawm mines thiab asbestos ua cov nroj tsuag thiab hauv nroog. Cov ntaub ntawv pov thawj pom tau tias 120 tus neeg mob tuag los ntawm pleural mesothelioma txhua xyoo. Xyoo 1976-96, 1314 tus neeg mob pulmonary asbestosis tau kuaj pom hauv tebchaws Poland. Tus naj npawb ntawm cov neeg mob tau nce 10% txhua xyoo.
Qhov xwm txheej yog ob npaug ntawm qhov chaw uas, piv txwv li, squares thiab txoj kev tau ntxiv dag zog nrog cov khib nyiab los ntawm kev tsim cov vaj huam sib luag. Qhov no tau tshwm sim, piv txwv li, hauv kev sib tham ntawm Shchutsin hauv lub xeev. Subcarpathian. Lub Hoobkas puas muaj? tsim cov vaj huam sib luag asbestos-cement ntau tshaj plaws hauv tebchaws Poland, "hais tias Agata Szczesna los ntawm General Inspectorate for Environmental Protection. - Ib puag ncig muaj kuab paug nrog cov plua plav asbestos los ntawm cov pob zeb qus hauv hav zoov thiab los ntawm cov haujlwm qhib tseem nyob. Thiab tseem los ntawm kev puas tsuaj ntawm cov vaj huam sib luag ntawm lub ru tsev thiab facades ntawm lub tsev?
