NgoDisemba 14 no-15, 2010, i-FDA yabiza iphaneli lesayensi ukuze liphinde lihlole udaba lokuchayeka kwe-mercury kusuka ekugcwalisweni kwamazinyo kwe-amalgam. Izisekelo ezimbili ezizimele, ezisizwa yi-IAOMT, zithunyelwe uG. Mark Richardson, PhD, weSNC Lavallin, Ottawa, Canada, owayekade eyi-Health Canada, ukuhlinzeka iphaneli lesayensi nabalawuli be-FDA ngokuhlola okusemthethweni kusetshenziswa imininingwane yakamuva evela ezincwadini zesayensi . Ukuhlolwa kwezingcuphe okwakushicilelwe phambilini kwakusukela eminyakeni yawo-1990. Khonamanjalo, ucwaningo olusha luye lwathola ubuthi obuningi obukhiqizwa ngamazinga aphansi okuvezwa kwe-mercury, futhi ama-ejensi ahlukahlukene kahulumeni abelokhu enciphisa amazinga okuvezwa kwawo okuvumelekile.
Umsebenzi wokugcina wethulwe lapha ezingxenyeni ezimbili.
Ingxenye 1 inesihloko esithi UKUBUYEKEZA UKUDALULA, UKUBUYEKEZA AMAZINGA OKUDALULA OKUBONAKALAYO, KANYE NOKUHLOLA KAKHULU IZIFUNDO ZAKAMUVA. “… Kwanqunywa ukuthi abanye abantu baseMelika abayizigidi ezingama-67.2 bazokweqa umthamo we-Hg ohlotshaniswa neREL ka-0.3 ug / m3 owasungulwa yi-US Environmental Protection Agency ngo-1995, kanti abantu baseMelika abayizigidi eziyi-122.3 babezodlula umthamo ohlotshaniswa neREL ka-0.03 ug / i-m3 yasungulwa yi-California Environmental Protection Agency ngo-2008. ”
Ingxenye 2 inesihloko esithi UKUHLOLWA KWENGOZI EQOKELELAYO NOKUXHUMANEKA KOBUTHO: I-MERCURY VAPOR, IMETHYL MERCURY AND LEAD. “Isibalo esikhulu - u-1/3 - wabantu base-US bavezwa kanyekanye ku-Hg0, i-methyl Hg ne-Pb nsuku zonke. Isisindo sobufakazi obutholakalayo sikhombisa ukuthi izingozi ezibangelwa ukuvezwa ngasikhathi sinye nezinhlanganisela zalezi zinto ezi-3 kufanele zihlolwe njengezengezo. ”
Buka i-Athikili:
UMark Richardson PhD uchaza indaba engemuva ekuhloleni ubungozi be-amalgam akwenze ngokubonisana ne-FDA.
