Possible Interaction: Silicon and Iron, Dietary

“Evidence is presented that iron apparently is a principal carcinogenic hazard in inhalation of silicon dioxide, asbestos, and tobacco smoke.”

“The doping of the silicon nanoparticles with iron led to additional production of hydroxyl radicals via the Fenton reaction.”

“Also, we found marginally significant (p<0.1) positive associations between iron and silicon in PM2.5 and diastolic blood pressure.”

“The effects of silicon and iron could not be separated.”

“In the absence of ascorbic acid, silicon also increased iron concentration in the liver.”

“The Fe and Al content of the fibers correlated negatively with the dissolution of Si by AMs from the MMVF, i.e., when the content of Fe and Al of the fibers increased the dissolution of Si decreased.”

“The addition of Si under normal conditions decreased the concentration of sugars in the roots, K and Mn in roots, and increased the concentration of Fe and Zn in shoots.”

“Here we directly measured thermal conductivities of … GPa and 3300 K. 15 at% Si … Fe substantially reduces its conductivity by about 2 folds at 132 GPa and 3000 K. An outer core … of about 20 W m −1 K −1 , lower than pure Fe at similar pressure–temperature conditions.”

“Furthermore, it is known that Si supply reduces the concentration of Fe in rice shoots.”

“Results also suggest that Si alleviated the negative impacts of Fe on spikelet sterility.”
