Assessment of the Impact of Gas Flaring on the pH, Cd, Pb, Cu, Zn, Fe and Mn Concentrations in the Rainwaters of Jeddo Community, Delta State, Nigeria (Published)

This paper is focused on the possible impact of gas flaring on the pH, Cd, Pb, Cu, Zn, Fe, and Mn concentrations in the rainwaters of Jeddo community, Delta State, Nigeria. The Rainwater samples were collected from two locations in the community. The samples were then taken to the laboratory for analyses. The result for the pH for both samples of Rainwater 1 (R1) and Rainwater 2 (R2) (which are 6.20 and 6.00 respectively) showed that their pH did not comply with the acceptable limits of World Health Organization (WHO, 2003), National Environmental Standards and Regulations Enforcement Agency (NESREA, 2011), Department of Petroleum Resources (DPR, 2002) and Nigerian Standard for Drinking Water Quality (NSDQW, 2007). The result also showed that Cd, Pb and Mn all complied with WHO (2003), NESREA (2011), DPR (2002) and NSDQW (2007) domestic/recreational water quality limits; while the values of Cu, Zn and Fe metals generally did not comply with the safety standards.

The Impact of Rock Crushing On the Quality of Air and Soil Within and Outside the Crushing Site (Published)

This study investigates the effect of rock crushing on Ishiagu environment in Enugu State, Nigeria. The quality of air dust and soil samples within and outside the crushing area was analyzed by taking samples of rock dust), soil and underground water. The amount of iron, zinc, copper, lead, cadmium, chromium and nickel were determined in the rock dust and soil samples collected within and outside the crushing sites. The results indicated that the concentration of metals in all samples were significant ranging from 1425-48180mg/kg in air dust sample, 120-44000mg/kg in soil samples while the metals in the underground water was seen to be decreasing as the distance from the crushing site increased .The underground water samples were observed to have high total dissolved solids (754,587 and 604) ppm respectively, total chloride and total hardness. All underground water samples were in excess of 150 mg/l total chloride with pH values between the ranges of 4.5 to 5.5 which is acidic.
