摘要:Lead (Pb) are toxic, carcinogenic, bioaccumulator and biomagnification. Pb bioaccumulation may occur in the nail, liver and hair. The research aimed to detect whether lead pollution has affected the people in North Semarang, using hair as bioindicator. The population of this explorative descriptive research was all residents of Sub-District of North Semarang. Samples were taken using purposive sampling technique, i.e. male residents of Tanjung Mas and Bandarharjo aged between 17 and 50 years, who have stayed in the sites for at least 5 years without interruption. The lead level in their body was detected from their hair strand using AAS (Atomic Absorption Spectrophotometery). Research showed that lead substance was detected in hair strands from 56 people. The highest level was 17.028 ppm and the average level was 8,304 ppm. It was suggested that the lead pollutant was not from motor vehicles emisions on the roads cause most samples were fishermen, instead it was suspected that the drinking water was the source of the lead. It was supported by the fact that the drinking water consumed daily by the residents has been contaminated by lead at the level of 6 ppm. Conclusion the lead pollution has affected some residents of North Semarang, ranging from low level to medium level. Presumably, the pollution was originated from the consumed drinking water.
