title: Effects on health of atmospheric lead in roadside exposure in Jakarta.
abstract: The effects of lead on the health of two Japanese males, ages 26 and 54, both of whom had previously resided in a Japanese city before staying for a period of one month in Jakarta, Republic of Indonesia. The subjects spent four to five days on a roadside in Jakarta where lead levels in the air varied from one to three μg/m(3), while that in Japan was approximately 0.1 μg/m(3). The followings were measured before, during and after the lead exposure: lead in blood, the activity of delta-aminolevulinic acid dehydratase, lead in urine per day and delta-aminolevulinic acid levels in urine per day. Lead in blood, the activity of delta-aminolevulinic acid dehydratase and lead in urine per day showed no marked changes, while delta-aminolevulinic acid levels in urine per day increased significantly after the exposure. Thus, lead and delta-aminolevulinic acid levels in urine per day are recommended as the most sensitive indicators of the short-term effect of lead.
