2001 年 7 月至 2005 年 3 月期间，在日本筑波观测到 TSP 和大气 210Pb 浓度。TSP 浓度范围为 14.5 至 152.4 µg m−3.210Pb 浓度范围为 0.04 至 0.86 mBq m−3，夏季较低，冬季至春季较高。尽管TSP浓度每年都在变化，但210Pb浓度具有几乎相同的浓度水平和季节变化。 210Pb浓度与NO3-浓度之间的相关系数略高于其他离子种类。这一结果表明两者都附着在相同的颗粒尺寸上并被运输到采样点。
TSP and atmospheric210Pb concentrations were observed at Tsukuba, Japan during July 2001 to March 2005. TSP concentrations ranged from 14.5 to 152.4 µg m−3.210Pb concentrations ranged from 0.04 to 0.86 mBq m−3which was low in summer and high in winter to spring. Although TSP concentrations changed annually,210Pb concentrations had almost the same concentration level and seasonal variation. The correlation coefficient between210Pb concentration and NO3−concentration was slightly higher than for other ion species. This result indicated that both had been attached to the same particle size and transported to the sampling site.
