Both airborne asbestos and non-asbestos fiber concentrations were evaluated in Korean non-occupational environments. The airborne fiber concentrations were analyzed in 96 air samples, from 48 different points, by transmission electron microscopy, with energy-dispersive X-ray analysis. The geometric means of the airborne asbestos and non-asbestos fiber concentrations were 0.62 and 67.86, and 0.30 and 17.47 fibers/liter in urban and rural areas, respectively. There were significant differences in both the airborne asbestos and non-asbestos fiber concentrations between the urban and rural areas (p<0.05). The geometric means of airborne asbestos and non-asbestos fiber concentrations were 0.67 and 37.93, and 0.27 and 30.67 fibers/liter at the points less than 10 m and more than 30 m away from highways, respectively. The airborne asbestos concentrations were significantly higher at the points less than 10 m away than at the points more than 30 m away from highways (p<0.01).
对韩国非职业环境中的空气传播石棉纤维和非石棉纤维浓度进行了评估。通过透射电子显微镜和能量色散X射线分析，对来自48个不同地点的96个空气样本中的空气传播纤维浓度进行了分析。城市和农村地区空气传播石棉纤维和非石棉纤维浓度的几何平均值分别为0.62和67.86，以及0.30和17.47纤维/升。城市和农村地区的空气传播石棉纤维和非石棉纤维浓度均存在显著差异（p<0.05）。距离高速公路小于10米和大于30米的地点，空气传播石棉纤维和非石棉纤维浓度的几何平均值分别为0.67和37.93，以及0.27和30.67纤维/升。距离高速公路小于10米的地点的空气传播石棉纤维浓度显著高于距离高速公路大于30米的地点（p<0.01）。
