He aha nā hopena o ka fiberglass i ke kino o ke kanaka?

Ma muli o ke ʻano palupalu o nā pulu aniani, ua haki lākou i nā ʻāpana fiber pōkole. Wahi a nā hoʻokolohua lōʻihi i alakaʻi ʻia e ka World Health Organization a me nā hui ʻē aʻe, hiki ke hoʻomoʻa ʻia nā fiber me ke anawaena o ka liʻiliʻi ma mua o 3 microns a me kahi hiʻohiʻona ʻoi aku ma mua o 5: 1 i loko o ka māmā o ke kanaka. ʻOi aku ka nui o nā fiber aniani a mākou e hoʻohana mau nei ma mua o 3 microns ke anawaena, no laila ʻaʻohe pono e hopohopo nui e pili ana i nā pōʻino o ka maʻi māmā.

In vivo dissolution haʻawina okīʻaha anianiua hōʻike i nā microcracks i loaʻa ma luna o ka ʻili o ke aniani i ka wā o ka hana ʻana e hoʻonui a hohonu ma lalo o ka hoʻouka ʻana o nā wai māmā alkaline nāwaliwali, e hoʻonui ana i ko lākou ʻili a me ka emi ʻana o ka ikaika o nā fibers aniani, no laila e wikiwiki ai ko lākou degradation. Ua hōʻike mai nā haʻawina e hoʻoheheʻe loa ʻia nā pulu aniani i loko o ka māmā i 1.2 a 3 mau mahina.

Wahi a nā pepa noiʻi mua, ʻaʻohe hopena koʻikoʻi i ka fibrosis a i ʻole ka ulu ʻana o ka ʻōpū, a ʻo ka hoʻokomo ʻana o nā aniani i loko o ka pleura o nā holoholona i hōʻike ʻia i ka fibrosis i loko o ka māmā. ʻAʻole i loaʻa i kā mākou mau noiʻi olakino o nā limahana i ka ʻoihana fiber aniani i nīnau ʻia i ka piʻi nui o ka maʻi pneumoconiosis, ka maʻi ʻaʻai māmā, a i ʻole ka pulmonary fibrosis, akā ua ʻike ʻia ua hoʻemi ʻia ka hana o ka māmā o nā limahana i hoʻohālikelike ʻia me ka lehulehu.

ʻOiaikīʻaha anianiʻAʻole lākou e pilikia i ke ola, hiki i ka hoʻopili pololei ʻana me nā pulu aniani ke hoʻonāukiuki i ka ʻili a me nā maka, a ʻo ka inhalation o nā ʻāpana lepo i loaʻa i nā fiber aniani ke hoʻonāukiuki i nā ʻāpana ihu, trachea, a me ka puʻu. ʻO nā hōʻailona o ka ukiuki ʻaʻole maʻamau a no ka manawa lōʻihi a hiki ke komo i ka ʻuʻu, ka ʻū a i ʻole ka uila. ʻO ka ʻike nui ʻana i ka fiberglass ea e hōʻeha paha i ka maʻi hānō a i ʻole ka maʻi bronchitis. ʻO ka maʻamau, e emi iho nā hōʻailona pili iā lākou iho i ka wā e neʻe aku ai ka mea i ʻike ʻia mai ke kumu o kaaniani uilano kekahi manawa.
