Tsaro da Abubuwan Samar da Titanium Dioxide a cikin 2017

Titanium dioxide (TiO2) yana ɗaya daga cikin mafi mahimmancin pigments a rayuwarmu ta yau da kullun. Yana da mahimmanci a cikin abubuwan yau da kullun kamar man goge baki, maganin rana, taunawa da fenti. Ya kasance a cikin labarai don mafi yawan 2017, farawa da farashi mafi girma. An samu gagarumin ci gaba a bangaren TiO2 na kasar Sin, wanda ya haifar da hauhawar farashin kayayyaki, kuma kasar Sin ta kuma takaita samar da kayayyaki saboda matsalar ingancin iska. Wata gobara ta Janairu 2017 a Huntsman's TiO2 shuka a Pori, Finland, ta ƙara iyakance ikon TiO2 don zane-zane.

Wannan ya haifar da masana'antun tawada don sanar da karuwar farashin tawada ta amfani da titanium dioxide; alal misali, Siegwerk ya fitar da sanarwa a farkon Maris yana sanar da ƙarin farashin duk tawada masu titanium dioxide.

Duk wannan yana da ƙalubale sosai, amma matsalolin muhalli yanzu sun taso wanda zai iya ɗaukar TiO2 zuwa wani, mafi wahala, matakin. TiO2 wani mahimmin sinadari ne a cikin hasken rana, kuma an sami damuwa a Turai game da amfani da nanoparticles a cikin hasken rana, man goge baki da sauransu. Damuwar, musamman, tana kan nanoparticles na TiO2. Wannan ya sa Hukumar Kula da Sinadarai ta Turai (ECHA) ta gano cewa titanium dioxide na iya zama carcinogen idan an shaka shi.
An sami taƙaitaccen bincike akan gubar titanium dioxide.

Kwanan nan, muhallin abinci na Faransa da Ofishin Lafiya da Tsaro na Ma'aikata (Anses) a cikin wata takarda, bisa ga bincikenta, sun nuna cewa yin amfani da titanium dioxide a matsayin mai yuwuwar cutar kansa ta hanyar shakar 1 B-carcinogens, wannan shawarar za ta kasance. bisa ga ka'ida a rubuce ko bayan zaman Satumba.

Labari ya ci tura a masana'antar. Kamfanonin titanium dioxide suna da ra'ayi. Titanium dioxide a ƙarshe ba abubuwan carcinogenic bane, lafiyar ɗan adam a ƙarshe babu wata illa mai yuwuwa?

"Titanium dioxide ba carcinogenic ba ne kuma ba shi da wani tasiri ga lafiyar ɗan adam," in ji Shijiang, Mataimakin Sakatare-Gene.ral na kungiyar masana'antun masana'antu ta kasar Sin. ”

Min, jinral manajan masana'antar titanium, ya ce: "Titanium dioxide wani abu ne mara guba, wanda ya tsunduma cikin masana'antar titanium dioxide fiye da shekaru 10, bai ji ba saboda titanium dioxide da cututtukan carcinogenic." Idan titanium dioxide carcinogenic ne, sakamakon zai iya zama babba. ”

Shin titanium dioxide lafiya?

Babu ainihin shaida cewa titanium dioxide carcinogenic ne. Na farko, gaba dayan abu kawai shawara ce ta yanayin abinci na Faransa da Ofishin Lafiya da Tsaro na Ma'aikata, kuma yana buƙatar ƙarin bincike.

Na biyu, muhallin abinci na Faransa da Ma'aikata Lafiya da Tsaro yana ba da shawarar haɗa titanium dioxide azaman 1-b carcinogen wanda zai iya haifar da ciwon daji ta hanyar numfashi. Bayanai kan takaddun da suka dace na lokaci-lokaci sun nuna cewa an sami cibiyoyi masu alaƙa a cikin kamfanin DuPont na Amurka titanium dioxide ma'aikata 2,477 don gudanar da bincike na gaba, sakamakon ya nuna cewa hulɗa kai tsaye da titanium dioxide ba zai ƙara haɓaka ma'aikatan huhu ba. ciwon daji, cututtuka na numfashi na kullum, pleural raunuka da sauran cututtuka masu alaƙa da haɗari.

Bugu da ƙari, nau'ikan bincike iri-iri iri-iri sun nuna cewa titanium dioxide baya haifar da fallasa ga yawan adadin cutar kansar huhu na hawan hawan. Bayanai daga hukumar bincike kan cutar daji ta kasa da kasa sun kuma nuna cewa babu isassun shaidu da za su iya tantance ko titanium dioxide na iya haifar da cutar kansa a jikin dan adam. Titanium dioxide ana amfani dashi sosai ba tare da maye gurbinsa ba.
