ABSTRACT
This study was carried out to examine heavy metals and polycyclic aromatic hydrocarbon concentration in Maggots located in Bayelsa state, Nigeria. The samples were digested and heavy metal PAHs analysis was carried out using Atomic Absorbance Spectrophotometer and Gas Chromatography respectively. From the results benzo[b]fluoranthene, benzo[k]fluoranthene, and benzo[a] pyrene as the highest concentration in the dried maggot samples with values 2.41ppm, 1.58ppm and 3.1 ppm respectively. The result for concentration of PAHs in fresh maggot indicates that the only PAHs available are Benzo[b] fluoranthene and Benzo[k]fluoranthene with values 0.04 and 0.01 ppm. The result for heavy metal in the two maggot samples indicates that the concentration in ascending orders is iron>zinc>manganese>copper with the other heavy metals been undetected in the samples.
