of calcium carbonate (both natural [i.e., oyster shell] and refined). Four out of seven natural products and four out of 14 refined products, including brand products, had measurable lead content. A research team in California found essentially the same contamination in calcium supplements.[12...
Synthesis and assessment of metallic ion migration through a novel calcium carbonate coating for biomedical implants Titanium (Ti) implants are commonly regarded as well accepted by the body. However, metal ion release is still a cause for concern. A small decrease in pH,... TB Le,LC Filho,...
associate professor in WSU's Department of Civil and Environmental Engineering, the researchers were able to unravel how nano-sized crystals form within concrete samples. The formation of these crystals resulted in stress buildup and calcium leaching in the concrete, both of which significantly reduced...
