Asbestos inoumbwa neshinda dzakanyanya kunaka dzinogona kurukwa nekuzvimba. Elastic, inopesana nechando uye kutonhora kwakanyanya, kune acids nezvimwe zvinhu zvinokonzeresa, yakanakira kugadzirwa kwemachira asingadziviriri moto (somuenzaniso, zvipfeko zvevanodzima moto), brake linings, kuvhara tambo. Asbestos iboka rematombo-ekugadzira zvicherwa anowanikwa mune zvakasikwa uye anozivikanwa kwezviuru zvemakore. Asi makore anoti pfuurei zvishoma zana apfuura, mukati menguva yechinjo yeindasitiri, akaita basa chairo. Sezvineiwo! Zvave zvichizivikanwa kweinenge chikamu chechina chezana remakore kuti mbishi iyi, inobatsira zvikuru mukugadzirwa kwezvinhu zvinenge zvitatu, ine carcinogenic.
MuPoland, inonyanya kushandiswa mukuvaka, kusanganisira dzimba. Mumakore ekuma60s nema70s, marata e-asbestos-simende mabhodhi (asbestosi-simende mabhodhi (asbestos) ekugadzira dzimba dzemhuri imwe chete uye zvekuvaka kunze, pamwe chete nemapuranga ekudzivirira aishandiswa kumadziro emadziro, akawana mukurumbira nekuti aive asingadhure.
Somugumisiro, pakutanga kwezana remakore rechi15,5, munyika yedu maiva nemamiriyoni 14,9 ematani ezvigadzirwa zveasbestos, kusanganisira mamiriyoni 600 ematani e-asbestos-cement slabs, 160 matani. matani epombi uye zviuru makumi matatu zvezvimwe zvigadzirwa zveasbestos-simende. Dambudziko hombe ndere izvo zvigadzirwa zvine hupenyu hwehunyanzvi, hunofungidzirwa kumakore makumi mashanu, hwave kupera. Izvi zvinosanganisira mataira easbestos, anowanzoregeredzwa uye asina kupendwa.
Zvikamu zveasbestos hazvifanirwe (kana kutombobvumidzwa) kuti zviparadzwe wega. Iwe haugone kufumura nharaunda yako, kusanganisira vamwe vanhu, kana iwe pachako kusvibiswa kweasbestos uye kurasikirwa kwehutano. Mahwendefa anogona kuchengetedzwa chete nekuapenda.
Mahwendefa akatyoka, ari kuputsika anopa njodzi huru. Iyo Construction Research Institute yakaverenga kuti kubva pa1 m2 nzvimbo yakakuvadzwa inogona kuburitsa kunyange zviuru zveasbestos fibers.
Kune marudzi akawanda azvo, asi anonyanya kutyisa ndeaya ekufema, kureva, ayo anogara ari mumhepo uye anopinda mumhepo yekufema. Vanopinda mukati me alveoli, iyo yavasingagoni kubviswa. Kunyanya kukuvadza kweasbestos kuri mukugumbura kwayo, zvichiita kuti asbestosis (asbestosis), kenza yemapapu, mesothelioma yepleura uye peritoneum.
Ongororo yakakura yezviitiko zverudzi urwu rwegomarara yakaratidza kuti kuwedzera kwechirwere ichi kunoonekwa munzvimbo dzemigodhi uye mafekitari easbestos nemumaguta. Nhamba dzepamutemo dzinoratidza kuti varwere ve120 vanofa nepleural mesothelioma gore rega rega. Muna 1976-96, 1314 nyaya dzepulmonary asbestosis dzakaonekwa muPoland. Huwandu hwenyaya huri kuwedzera ne10% pagore.
Chiitiko chacho chakapetwa kaviri munzvimbo umo, semuenzaniso, zvikwere nemigwagwa zvakasimbiswa nemarara anogadzirwa panguva yekugadzirwa kwemapuranga. Izvi zvakaitika, semuenzaniso, munharaunda yeSchutsin mudunhu. Podkarpatsky. Fekitari iriko here? inogadzira huwandu hukuru hwemasimende esimende muPoland,” anodaro Agata Szczesna anobva kuMain Inspectorate for Environmental Protection. – Mhoteredzo inoramba ichisvibiswa neguruva reasbestos rinobva kumarara mumasango nemumigodhi yakavhurika. Uye zvakare kubva kune dzakakuvadzwa nzvimbo dzepaneru pamatenga uye facades ezvivakwa?
