Two elementary schools (Shiuguang and Fongrong) from Yulin County in Taiwan, near a main area of potential exposure to Aeolian river-dust, were selected to collect outdoor and indoor PM aerosols and to measure five metals in PM (As, Ni, Cr, Cd, and Mn). Significant relationships (p < 0.01) were found between outdoor PM concentrations at Lunbei's air quality monitoring station and the two elementary schools. The outdoor PM concentrations at the monitoring station and the schools' indoor PM concentrations also showed significant correlations. This study also established a relationship between the outdoor and indoor concentrations of PM and metals in the schools. Estimations were made regarding students' 8 h of exposure to metal concentrations from river-dust episodes during 1994-2012, based on correlation equations that were shown to be statistically significant.
台湾榆林县的两所小学（曙光小学和丰荣小学）靠近一个潜在的风尘暴露主要区域，被选来收集室外和室内的颗粒物气溶胶，并测量颗粒物中的五种金属（砷、镍、铬、镉和锰）。在仑背空气质量监测站的室外颗粒物浓度与这两所小学之间发现了显著关系（p < 0.01）。监测站的室外颗粒物浓度与学校的室内颗粒物浓度也显示出显著相关性。本研究还建立了学校室外和室内颗粒物及金属浓度之间的关系。基于具有统计学显著性的相关方程，对1994 - 2012年期间学生因风尘事件接触金属浓度8小时的情况进行了估算。
