Chemical Composition of Harvested Rainwater around a Cement Factory inIbeshe, Yewa North, Ogun State

Abstract

This study assessed the physicochemical properties of rainwater in Ibeshe, an area around the Dangote Cementfactory in Ogun State. Rainwater samples were collected as bulk precipitation from April – September 2022 atweekly intervals. Collected rainwater samples were analyzed for basic composite variables (pH, electricalconductivity, temperature, and total dissolved solids using a portable pH meter and conductivity meter respectively),and major cations (magnesium, sodium, calcium, iron, arsenic, lead, and silicon). The AGILENT 720 ICP-OES wasused for Mg2+, Na+, Ca2+, Fe2+, K+, and Pb2+. All the results obtained show that rainwater in the study area was basic(6.73 – 7.63) and all the parameters were within the WHO limit. Also, it was observed that the activities of thecement mining plant had little or no influence on the chemistry of the rainwater in the study area
