Blood lead levels (BLLs) of 188 pediatric patients were measured and their parents were queried as to the smoking style in their home. Their mean BLL was 3.16 μg/dl, which was among the lowest levels in the world, and none of them had levels of over 10 μ g/dl. Preschool children ( 1 to 6 years of age) with parents who smoked in the same room had a significantly higher BLL (mean; 4.15 μ g/dl) than those with parents who never smoked (mean; 3.06 μ g/dl) (P<0.01). However, the mean BLL of school children (6 to 15 years of age) with parents who smoked in the same room was not significantly different from that of school children with parents who never smoked. Passive smoking caused an increase of the BLL only in preschool children in Japan. This is probably because preschool infants spend much more time with their parents and have much more contact with passive smoking than school children and, additionally young infants have a limited ability to excrete lead from the body.
检测了 188 名儿科患者的血铅水平 (BLL)，并询问其父母家中的吸烟方式。他们的平均 BLL 为 3.16μg/dl，处于世界最低水平之列，且无一例患者的 BLL 超过 10μg/dl。与父母从不在家中同一房间吸烟的儿童（1 至 6 岁）相比，父母在家中同一房间吸烟的学龄前儿童（1 至 6 岁）的 BLL 明显更高（均值分别为 4.15μg/dl 和 3.06μg/dl）（P<0.01）。然而，家中同一房间吸烟的学龄儿童（6 至 15 岁）的平均 BLL 与父母从不吸烟的儿童相比并无显著差异。在日本，被动吸烟仅会导致学龄前儿童的 BLL 升高。这可能是因为学龄前婴儿与父母在一起的时间要长得多，与被动吸烟的接触也多得多，此外，婴幼儿从体内排出铅的能力有限。
