Martanin IAOMT ga Kwamitin Masu Ba da Shawarwari na Kimiyya (BSC) Shirin Tsarin Toxicology na Ƙasa (NTP)

Bayanin Baki na IAOMT na NTP BSC

Sannu, ni Dr. Jack Kall, likitan hakori na shekaru 46. Ni ne Shugaban Hukumar Gudanarwa na Cibiyar Nazarin Magungunan Baka da Magunguna ta Duniya, ko IAOMT. Mu kungiya ce mai zaman kanta da aka kafa a 1984.

3. fluoride da ake amfani da shi wajen kurkura, man goge baki, varnishes, siminti da kayan cikawa

Wadannan duk ana saka su kai tsaye cikin baki. Bugu da ƙari, ana amfani da fluoride a cikin hanyoyin sha kai tsaye a cikin nau'in ruwan sha mai ƙyalƙyali, gishiri mai fluoridated, da kari na fluoride.

Sama da shekaru 30 ƙungiyarmu tana tallafawa da ba da kuɗi don bincike kan gubar fluoride. Mun kasance da sha'awar musamman kuma mun damu sosai game da binciken da aka buga kwanan nan game da neurotoxicity na fluoride don haka muna goyan bayan nazarin tsarin NTP.

Mun ji takaicin yadda fluoridation-indalying hakori bukatun a cikin gwamnatin tarayya da kuma wajenta, suna kokarin yin tasiri a kan sakamakon NTP, ba bisa kimiyya, amma a kokarin kare manufofinsu na inganta ruwa fluoridation.

Menene mabuɗin binciken NTP?
