Abstract

This study was conducted to determine physico-chemical parameters and nutrient levels on a seasonally basis of Agnéby river in the southern regions of Ivory Coast. Theses parameters were analyzed at ten sampling stations situated along the watercourses in the period of rainy season (November 2011 and July 2012) and dry seasons (August 2011 and February 2012). The highest average values of pH, temperature, conductivity, dissolved oxygen and turbidity were determined as 7.34, 28.25°C, 267 µS/cm, 8.15 mg/l and 66.2 NTU, respectively. Nutrients varied according sampling sites but showed no significant differences between dry and rainy seasons. The obtained results indicate …..

Abstract

Pollutant standards indices (PSI) were computed for each study area to indicate the concentration level of each pollutant in the study area, while air quality indices were computed to show the degree of air pollution effects on human health in Port Harcourt and its environs. The Air Quality index (AQI) revealed the health effects on people in the respective study area may be experienced. Results of AQI indicated that Eleme, Obio/Akpor and Port Harcourt are most polluted areas compared to Oyigbo, Ikwerre Local Government Area (LGA) and Etche in the dry season…..
