ʻO nā pilikia palekana a me nā lako lako o Titanium Dioxide ma 2017

ʻO Titanium dioxide (TiO2) kekahi o nā puaʻa koʻikoʻi i ko mākou ola i kēlā me kēia lā. He mea koʻikoʻi ia i nā mea o kēlā me kēia lā e like me ka toothpaste, sunscreen, chewing gums a me nā pena. Aia ia ma ka nūhou no ka hapa nui o 2017, e hoʻomaka ana me nā kumukūʻai kiʻekiʻe. Ua hoʻohui nui ʻia ma ka ʻāpana TiO2 o Kina, e alakaʻi ana i nā kumukūʻai kiʻekiʻe, a ua hōʻike pū ʻia ʻo Kina i ka hoʻopaʻa ʻana ma muli o nā hopohopo ea. He ahi o Ianuali 2017 ma Huntsman's TiO2 mea kanu ma Pori, Finland, i kaohi hou aku i ka hiki no TiO2 no ka hana kii.

Ua alakaʻi kēia i nā mea hana inika e hoʻolaha i ka piʻi ʻana o ke kumukūʻai ma nā inika me ka hoʻohana ʻana i ka titanium dioxide; no ka laʻana, ua hoʻopuka ʻo Siegwerk i kahi ʻōlelo i ka hoʻomaka ʻana o Malaki e hoʻolaha ana i nā kumukūʻai kiʻekiʻe no nā inika āpau i loaʻa ka titanium dioxide.

He paʻakikī kēia mau mea a pau, akā ua hiki mai nā pilikia kaiapuni i hiki ke lawe iā TiO2 i kahi pae ʻē aʻe, ʻoi aku ka paʻakikī. ʻO ka TiO2 kahi mea nui i ka sunscreens, a aia nā hopohopo ma ʻEulopa no ka hoʻohana ʻana i nā nanoparticles i ka sunscreen, toothpaste a me nā mea hou aku. ʻO ka hopohopo, ʻo ia hoʻi, ma luna o nā nanoparticles o TiO2. Ua alakaʻi kēia i ka European Chemical Agency (ECHA) e hoʻoholo e hiki ke lilo ka titanium dioxide i mea make ke hoʻohu ʻia.
Ua kaupalena ʻia nā haʻawina e pili ana i ka ʻona o ka titanium dioxide.

I kēia mau lā, ʻo ka French food environment a me ka occupational Health and Safety Bureau (Anses) i loko o kahi pepa, e like me kāna mau ʻike, ua manaʻo ʻia ka hoʻohana ʻana o ka titanium dioxide i kumu kumu o ka maʻi kanesa ma o ka inhalation o 1 B-type carcinogens, e lilo kēia noi. apono ʻia ma ke kākau ʻana a i ʻole ma hope o ke kau o Kepakemapa.

Ua ulu ka nūhou i ka ʻoihana. Loaʻa ka manaʻo o nā ʻoihana Titanium dioxide. ʻO Titanium dioxide i ka hopena ʻaʻole ia he mea carcinogenic, ʻo ke olakino kanaka i ka hopena ʻaʻohe mea pōʻino?

"ʻAʻole he carcinogenic ka Titanium dioxide a ʻaʻohe hopena i ke olakino kanaka," wahi a Shijiang, Hope Kakauolelo-Gene.ral o ka Hui ʻOihana Hoʻonaʻauao Kina. ”

Min, general luna o ka ʻoihana titanium, i ʻōlelo ʻia: "ʻO Titanium dioxide nā mea ʻawaʻawa ʻole, e hana ana i ka ʻoihana titanium dioxide no nā makahiki he 10, ʻaʻole i lohe ma muli o ka titanium dioxide a me nā hihia carcinogenic." Inā he carcinogenic ka titanium dioxide, hiki ke nui ka hopena. ”

Ua palekana anei ka titanium dioxide?

ʻAʻohe mea hōʻike maoli he carcinogenic ka titanium dioxide. ʻO ka mea mua, ʻo ka mea holoʻokoʻa he manaʻo wale nō ia e ka French food environment and occupational Health and Safety Bureau, a pono ia e noiʻi hou aku.

ʻO ka lua, ʻo ke kaiapuni meaʻai Farani a me ka ʻoihana Health and Safety Administration ke ʻōlelo wale nei i ka hoʻopili ʻana o ka titanium dioxide ma ke ʻano he carcinogen 1-b e hiki ai ke hoʻoulu i ka maʻi kanesa ma ka inhalation. Hōʻike ka ʻike e pili ana i nā palapala manawa kūpono e pili ana i nā hui pili i ka United States DuPont company titanium dioxide production plant 2,477 limahana e hana i ka noiʻi hahai, hōʻike nā hopena i ka hoʻopili pololei ʻana me ka titanium dioxide ʻaʻole e hoʻonui nui i nā limahana o ka māmā. ma'i 'a'ai, ma'i hanu mau, pleural nā ʻeha a me nā maʻi e pili ana.

Eia kekahi, ua hōʻike ʻia nā ʻano ʻano like like ʻole i ka titanium dioxide ʻaʻole ia e hōʻike i ka heluna kanaka o ka maʻi maʻi maʻi maʻi maʻi maʻi maʻi i ka piʻi ʻana. Hōʻike pū ka ʻikepili mai ka International Agency for Cancer Research ʻaʻole lawa nā hōʻike e loiloi inā hiki i ka titanium dioxide ke hoʻoulu i ka maʻi kanesa i loko o ke kanaka. Hoʻohana nui ʻia ka Titanium dioxide me ka ʻole o nā mea pani.
