The objective of this research was to analyze air Pb level, blood Pb level, and its effects on the street vendors’ disorders. This was an analytic observational research, conducted in 2004, applying cross sectional study on street vendors who vend on pavement rims. Respondents divided into 2 groups; first, street vendors who vend at high traffic location, that is Dharmawangsa street, and second, those who vend at low traffic site, that is Dharmahusada Indah Timur street. The number of samples were 20 for each group. Analysis was done on the ambient air Pb level, blood Pb level of street vendors’ and street vendors’ health disorders, i.e. blood Hb levels, blood pressures, headaches, memory deterioration, concentration difficulties, bone and muscle pains, tremors, appetite, gastric pains, and constipation.
The results showed that the average ambient air Pb level at Dharmahusada Indah Timur street was 0.15 ìg/m3, which was below Environmental Quality Standard (EQS), whereas the average ambient air Pb level at Dharmawangsa street was 2.71 ìg/m3, which was slightly above EQS. Both blood Pb level of street vendors’ at Dharmawangsa street and Dharmahusada Indah Timur street were still within normal level. The ambient air Pb level on research location had an influence on street vendors’ blood Pb level (p = 0.002). The blood Pb level had no influence on the street vendors’ health disorders (constant, p = 0.000).
