I-Azbest

i-asbestos ngaphansi kwesibonakhulu se-electron

I-asbestos yenziwe ngemicu emihle kakhulu engalukwa futhi ivuvuke. I-Elastic, imelana nesithwathwa namazinga okushisa aphezulu, kuma-acids nezinye izinto ze-caustic, ilungele ukukhiqizwa kwezindwangu ezingashi (isibonelo, izingubo zabacimi bomlilo), ama-brake linings, izintambo zokuvala. I-Asbestos iyiqembu lamaminerali akha amatshe atholakala emvelweni futhi aziwa izinkulungwane zeminyaka. Kodwa eminyakeni engaphezudlwana nje kwekhulu edlule, phakathi nenkathi yenguquko yezimboni, wenza umsebenzi wangempela. Ngeshwa! Sekwaziwa cishe ingxenye yesine yekhulu leminyaka ukuthi le nto eluhlaza, ewusizo kakhulu ekukhiqizweni kwemikhiqizo emi-3, i-carcinogenic.

E-Poland, isetshenziswa kakhulu ekwakheni, kuhlanganise nezindlu. Ngeminyaka yawo-60s kanye nama-70s, amabhodi e-asbestos-simende (amabhodi e-asbestos-simende (i-asbestos) okushelela izindlu zomndeni owodwa kanye nezakhiwo zangaphandle, kanye namabhodi okuvikela asetshenziselwa izindonga ze-sheathing block, athola ukuthandwa okukhulu ngoba ayengabizi.

Ngenxa yalokho, ekuqaleni kwekhulu lama-15,5, kwakukhona amathani angaba yizigidi ezingu-14,9 emikhiqizo equkethe i-asbestos ezweni lethu, kuhlanganise namathani angaba yizigidi ezingu-600 zama-slabs-asbestos-cement, amathani angu-160. amathani amapayipi kanye amathani ayizinkulungwane ezingu-30 eminye imikhiqizo asbestos-usimende. Inkinga enkulu yileyo mikhiqizo impilo yayo yobuchwepheshe, elinganiselwa eminyakeni eyi-XNUMX, isizophela. Lokhu kufaka phakathi amathayela e-asbestos, avame ukunganakwa futhi angapendiwe.

Izingxenye ze-asbestos akufanele (noma zize zivunyelwe) ukuba zihlakazwe uwena. Akumele uveze indawo okuyo, okuhlanganisa nabanye abantu, noma wena ngokwakho ekungcoleni kwe-asbestos kanye nokulahlekelwa yimpilo. Amapuleti angavikelwa kuphela ngokuwapenda.

Amapuleti aphukile, adilikayo adala ingozi enkulu. I-Construction Research Institute ibale ukuthi ukusuka ku-1 m² indawo eyonakele ingakhulula ngisho nezinkulungwane ezimbalwa zemicu ye-asbestos.

Kunezinhlobo eziningi zazo, kodwa eziyingozi kakhulu yizo zokuphefumula, okungukuthi, lezo ezihlala zihlala emoyeni futhi zingena emgudwini wokuphefumula. Zingena ku-alveoli, lapho zingenakususwa khona. Ukulimaza okuyinhloko kwe-asbestos kusemphumela wayo ocasulayo, okuholela ku-asbestosis (asbestosis), umdlavuza wamaphaphu, i-mesothelioma ye-pleura ne-peritoneum.

Ucwaningo olukhudlwana lwezigameko zalolu hlobo lomdlavuza lubonise ukuthi ukwanda kwalesi sifo kubonakala endaweni yezimayini kanye nezitshalo zokucubungula i-asbestos nasemadolobheni. Izibalo ezisemthethweni zibonisa ukuthi iziguli eziyi-120 zibulawa i-pleural mesothelioma minyaka yonke. Ngo-1976-96, kwatholakala amacala ayi-1314 e-asbestosis yamaphaphu ePoland. Inani lamacala likhula ngo-10% ngonyaka.

Isigameko siphindwe kabili ezindaweni lapho, isibonelo, izikwele nemigwaqo ziqiniswe ngemfucuza ekhiqizwa ngesikhathi sokukhiqizwa kwamaphaneli. Lokhu kwenzeka, isibonelo, endaweni yaseSchutsin esifundazweni. I-Podkarpatsky Ingabe imboni ikhona lapho? ikhiqiza isamba esikhulu samaphaneli kasimende we-asbestos ePoland,” kusho u-Agata Szczesna we-Main Inspectorate for Environmental Protection. – Imvelo iyaqhubeka nokungcoliswa uthuli lwe-asbestos oluvela ezindaweni ezilahlwayo zasendle emahlathini nasezimayini zemigodi evulekile. Futhi kusuka ezindaweni ezilimele zamaphaneli ophahleni nama-facade wezakhiwo?
