Issue Addressed: This study investigated the impact of removing sugar sweetened beverages (SSBs) from sale in a regional health service. Drink purchasing patterns were measured by product ordering data. Consumer opinion regarding the intervention, self-reported packaged drink purchase and consumption were also explored.

How reliable are crystalline silica dust concentration measurements?

To determine how reliably commercial laboratories measure crystalline silica concentrations corresponding to OSHA's proposed limits, 105 filters were prepared with known masses of 20, 40, and 80 μg of respirable quartz corresponding to airborne silica concentrations of 25, 50, and 100 μg/m(3) and were submitted, in a blind test, to qualified commercial laboratories over a nine month period. Under these test conditions, the reported results indicated a lack of accuracy and precision needed to reliably inform regulatory compliance decisions. This was true even for filters containing only silica, without an interfering matrix.
