Silica exposure in a mining exploration operation

Silica concentrations were higher among workers in the core cutting and core sorting (pulp and reject) areas, as compared to those in the core logging area. CONCLUSIONS: Workers employed in core processing facilities as part of mining exploration activities are exposed to respirable silica; exposure controls may be needed. PubMed link to article

5 Potential Human Health Effects of Uranium Mining ...

Silica overexposure is a potential hazard whenever resource extraction such as mining (underground or open-pit) or ore processing involves silica-bearing materials. The geology of uranium-bearing ore deposits is such that typically concomitant silica exposure cannot be avoided during mining and processing uranium.

What Is Silica and How Can it Support Your Health?

May 19, 2016 · Humans use silica as a food additive and a filler in drugs and vitamins. It has a low bioavailability, meaning your body will only absorb a tiny amount of silica and excrete the rest in urine. Most of the silica in your body is in a form called orthosilicic acid. It exists in your bones, tendons, aorta, liver, and kidneys.
