Evaluation of the On-Site and Off-Site Ambient Air Quality (AAQ) At Nekede Waste Dumpsite, Imo State, Nigeria.

Abstract

The study focused on the evaluation of the on-site and off-site ambient air quality at Nekede dumpsite. It sought to find out the concentration of Methane (CH4), Carbon (NH3), Nitrogen (IV), Oxide (NO2), Particulate Matter (PM10) and Sulphur (IV) Oxide (SO2) from the waste dumpsite to a distance of 300 meters. Samples were collected on four sampling points, one hundred meters apart between the month of March and May, 2014. The data was collected in two sessions (morning and evening) using the Crowcon Portable Gas Analyzer. Result show that with the exception of CO, other air pollutants (CH4, H2S, NH3, NO2, PM10 and SO2) observed exceeded the concentration values stipulated by FMENV, WHO and USEPA.
