The results showed that the aluminum plates had a much better effect than zinc plates in identifying crystalline free silica. The all open-faced samples had good uniformity in the filter no matter how many middles were used, but not so good for the closed-faced sampling. The calibration curve had a good correlation coefficient (r=0.995). Due to different industrial operating patterns, the distribution of crystalline free silica concentration varied by the industrial environment. The dust consisted of 10- 30% of crystalline free silica in all samples obtained from the foundry environments. The crystalline free silica was accounted for less than 10% in the respirable dusts.

结果显示，因为铝板对於结晶型游离二氧化矽具有较良好的补正系数，因此做为本研究的基底标准吸收校正的校正元素；SKC铝制旋风分离器搭配开匣式滤纸匣於一阶中环、二阶中环、三阶中环均有良好之均匀度，反之，搭配闭匣式滤纸匣其均匀度均不佳；分析检量线具有良好线性关系(r=0.995)，因作业型态不同，作业环境会有不同的浓度分布，综观作业环境中可呼吸性结晶型游离二氧化矽之含量均小於10%以下，总粉尘结晶型游离二氧化矽之含量约为10 – 30%之中。
