（1）Cadmium can enter embryo by permeating placenta barrier and enter brain partly and oosperm can not develop as embryo in the high dose group.（2）The decreasing of some neural transmitter and capacity of anti-oxidation are related to the content and contribution of zinc in embryoes.

（1）镉可透过胎盘屏障和部分透过血脑屏障，高镉可致受精卵不能发育为胚胎；（2）母鼠染镉可致胎鼠脑组织5-HT合成减少，抗氧化能力减弱；这些改变与锌的含量和分布改变有关。

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。
