Measured Fine dust concentrations in outdoor air.

Crude accidental gliding 24-hour values of fine dust (PM10) at ground level in the outdoor air measured in the National Air Quality Monitoring Network (LML). Dust is a collective name for all particles that float in the air. If the diameter of the particles is less than 10 micrometres, fine dust is used. Fine dust has many sources and are also formed by chemical reactions in the air. The legal standard is an annual average of 40 micrograms per cubic meter. In addition, the daily average may be up to 35 times higher than 50 micrograms per cubic metre per year. Fine dust has an effect on human health. Also under the legal standards.本数据集为国家空气质量监测网络（National Air Quality Monitoring Network，简称LML）测得的室外空气地面层细颗粒物（PM10）的原始滑动24小时实测值。 粉尘是空气中所有漂浮颗粒物的统称，当颗粒物直径小于10微米时，即称为细颗粒物。细颗粒物来源多样，亦可通过空气中的化学反应生成。法定标准为年平均浓度不超过40微克每立方米。此外，日平均浓度最高可达50微克每立方米的35倍。细颗粒物会对人体健康造成不良影响，即便在符合法定标准的情况下亦是如此。
