Abstract: The paper investigates trace metal concentration in rainwater from four locations namely: New Benin, Ring Road, University of Benin Campus and Oluku areas all situated in Benin Metropolis of Edo State, Nigeria. PerkinElmer Optima 5300DV inductively coupled plasma - optical emission spectrometry (ICP-OES) was utilised for chemical analysis of Aluminium, Calcium, Potassium, Magnesium, Sodium, Silicon, Tin, Strontium, Boron and Sulphur. The results of conductivity range of 5.65-83.15 μScm-1 and mean pH range of 5.47-6.76 obtained from rainwater samples establishes that some of the samples could be termed as acid rain. Calcium, Potassium, Sodium and Sulphur had a mean concentration of trace metal which was measured to be greater than 100 µg/L; concentrations of Aluminium and Magnesium were between 1-100 µg/L while Silicon and Strontium were found to be below detection limit. This study therefore reveals that the rainwater samples collected at New Benin and Ring Road were found to record the highest contamination of trace metal concentration as compared to other sampling sites.
