Abstract
12 soil and dust samples were collected from the e-waste recycling and dismantling locations in Lagos with a view to assess the health risk associated with these study sites. The digestion of the soil and dust samples was carried out using aqua regia prior to the determination of heavy metal by MP-AES. The e-waste soils were the most contaminated with higher concentration of trace metals compared to the road side soils and indoor dust. Lawanson and Alaba e-waste soils had the highest concentration of Cu (4147.71µg/g and 1820.30 μg/g) respectively; lowest concentration of Cu was from Westminister e-waste soil (32.61μg/g). Agbara Morogbo e-waste soil had the highest concentration of Cd-(662.47μg/g), Pb-(791.03μg/g) and As-(258.75μg/g). The lowest concentration of Cd-(22.46μg/g) and Pb-(54.73μg/g) was from Alaba e-waste soil. Lawanson road side soil was the most contaminated with trace metals (As-74.31μg/g; Cd-254.89μg/g; Cu-2263.84μg/g; Pb-312.67μg/g) compared to other road side locations. Lawanson indoor dust was the most polluted dust with Pb and Westminister indoor dust contain the highest level of Cd (126.71 μg/g). The highest and lowest As levels (58.76μg/g and 0.87μg/g) were from Alaba and Agbara Morogbo indoor dust respectively. Agbara Morogbo indoor dust had the highest concentration (910.98μg/g) of Cu. Tessier’s sequential extraction method was used to determine the degree of pollution and partition the trace elements in the most contamination soil (Lawanson e-waste and road side soils). The health risk assessment of the heavy metals in Lawanson soil and dust predicted that children are of higher risk of serious health problems than adults in the future.
