John Newton 4 December, 300} .Analyst Date of Analysis Disclaimer; The laboratory can only verify tlic concentrations ofunaiytcs on the filter and not the final cowcninitioiis due to data obtained by non-lahoratory personnel. Id the nhsence of a bulk dust sample, the specific form of crystalline silica can not be determined. Hence, alpha-quartz, the mo« prevalent form atctysullinc silica, will be assumod. = Less tfian the stated value The lowciit rcporlable value is equivalent to the .Analytical Sensitivity which is calculated from the lowest reproducible conceocrarion ofsilia detectable by the inslrumcnt.
