Lead, Soil, Water, Blood


The researchers collected composite soil and tap water samples from each junk shop. To measure lead concentration in soil and tap water samples. Flame atomic absorption spectrophotometer (FAAS) was utilized. A 5 mL venous blood sample was extracted from each participant then placed in EDTA tube at 4°C. Blood lead levels were determined using graphite Furnace Atomic Absorption Spectrophotometer. The results of the study showed that the concentration of lead in blood, soil, and tap water of ULAB collectors obtained within the vicinity of the junkshop with reference to the mean as 6.55 ug/dL, 45.61 mg/kg and 0.003 respectively. The study concluded that there is a significant relationship between the ULABs and blood, and ULABs and soil. However, there is no significant relationship between ULABs and tap water, as the results are within the normal value. The study concluded the ULABs collected by junk shops are significant sources of lead exposure to junk shop scavengers and soil.
