Hana ʻia ʻo Asbestos me nā fiber maikaʻi loa i hiki ke ulana ʻia a pehu. ʻO Elastic, kūpaʻa i ka hau a me nā mahana kiʻekiʻe, i nā waikawa a me nā mea caustic ʻē aʻe, he mea kūpono ia no ka hana ʻana i nā lole pale ahi (e like me nā lole no nā mea puhi ahi), nā pale pale, nā kaula hoʻopaʻa. ʻO Asbestos kahi pūʻulu o nā minerala pōhaku i loaʻa i ke ʻano a ʻike ʻia no nā kaukani makahiki. Akā ma kahi o hoʻokahi haneli mau makahiki i hala aku nei, i ka wā o ka hoʻololi ʻana i ka ʻoihana, ua hana ʻo ia i kahi ʻoihana maoli. Minamina! Ua ʻike ʻia ma kahi o ka hapahā o ke kenekulia ʻo kēia mea maka, pono loa no ka hana ʻana o nā huahana 3, he carcinogenic.

Ma Polani, hoʻohana nui ʻia i ke kūkulu ʻana, me ka hale. I nā makahiki 60 a me 70, ua kaulana nā papa asbestos-cement corrugated (asbestos-cement boards (asbestos) no ka uhi ʻana i nā hale ʻohana hoʻokahi a me nā hale i waho, a me nā papa insulating i hoʻohana ʻia no ka sheathing block walls, no ka mea ʻuʻuku lākou.

ʻO ka hopena, i ka hoʻomaka ʻana o ke kenekulia 15,5, aia ma kahi o 14,9 miliona mau mea i loaʻa i ka asbestos i loko o ko mākou ʻāina, ʻo ia hoʻi ma kahi o 600 miliona mau tone o nā papa asbestos-cement, 160 tons. nā tona o nā paipu a me 30 tausani tona o nā huahana asbestos-cement. ʻO ka pilikia nui loa ʻo ia nā huahana nona ke ola ʻenehana, i manaʻo ʻia ma XNUMX mau makahiki, kokoke e pau. Hoʻopili kēia i nā tile asbestos, i mālama ʻole ʻia a pena ʻole ʻia.

ʻAʻole pono (a ʻae ʻia paha) nā ʻāpana asbestos e wehe iā ʻoe iho. ʻAʻole hiki iā ʻoe ke hōʻike i kou kaiapuni, me nā poʻe ʻē aʻe, a i ʻole ʻoe iā ʻoe iho i ka palaka asbestos a me ka nalowale o ke olakino. Hiki ke pale wale ʻia nā papa ma ka pena ʻana iā lākou.

ʻO nā papa haʻihaʻi, ʻāwili ʻia ka pilikia nui loa. Ua helu ka hale noiʻi kūkulu hale mai 1 m² hiki i ka ʻili i pohō ke hoʻokuʻu i nā kaukani asbestos fiber.

Nui nā ʻano o ia mau mea, akā ʻo ka mea weliweli loa ka hanu, ʻo ia hoʻi, nā mea e noho mau i ka lewa a komo i ka ʻōpū hanu. Komo lākou i loko o ka alveoli, kahi hiki ʻole ke wehe ʻia. ʻO ka pōʻino nui o ka asbestos aia i kona hopena hoʻonāukiuki, e alakaʻi ana i ka asbestosis (asbestosis), ka maʻi maʻi maʻi, mesothelioma o ka pleura a me ka peritoneum.

ʻO kahi noiʻi nui aʻe o ka loaʻa ʻana o kēia ʻano maʻi maʻi i hōʻike ʻia ua ʻike ʻia ka piʻi ʻana o ka maʻi ma kahi o nā mines a me nā mea kanu asbestos a me nā kūlanakauhale. Hōʻike nā ʻikepili kūhelu he 120 mau maʻi e make ana mai ka pleural mesothelioma i kēlā me kēia makahiki. Ma 1976–96, 1314 mau hihia o ka pulmonary asbestosis i ʻike ʻia ma Polani. Ke piʻi nei ka nui o nā hihia ma 10% i kēlā me kēia makahiki.

He papalua ka heluna ma nā wahi, no ka laʻana, ua hoʻoikaika ʻia nā ʻāpana a me nā alanui me nā ʻōpala mai ka hana ʻana o nā panela. Ua hana ʻia kēia, no ka laʻana, ma ke kamaʻāina ʻo Shchutsin ma ka ʻāina. Subcarpathian. Aia ka hale hana ma laila? e hana ana i ka heluna nui loa o na panela asbestos-cement ma Polani,” wahi a Agata Szczesna mai ka General Inspectorate for Environmental Protection. - ʻO ka haumia o ke kaiapuni me ka lepo asbestos mai nā ʻōpala ʻāhiu i loko o nā ululāʻau a me nā wahi hana hāmama. A no hoi mai poino surfaces o panels ma luna o ka hale a me facades o na hale?
