Abstract

The present study aims to compare physico-chemical parameters of Agneby and Me rivers of Cote d'Ivoire. A total of eight (8) physico-chemical parameters were determined in nine (9) localities surveyed on both the Agneby and Me Rivers. Sampling were carried out on a seasonal frequency between August 2015 and July 2016. Principal Component Analysis (PCA) of both rivers showed that Agneby River localities were characterized by warm water (27.08 ± 0.87°C), neutral pH (7.07 ± 0.26), high salinity (0.05 ± 0.04 ‰), relatively high levels of dissolved substances (58.01 ± 32.19 mg/L), and low resistivity (26.97 ± 22.46 kΩ/cm) compared to Me River localities. Bravais Pearson correlation matrix between physico-chemical parameters of both rivers showed a strongly significant positive correlation between salinity and conductivity (0.89), salinity (0.90) and TDS, conductivity (0.91) and total dissolved solids, and a negative highly correlation was observed respectively between pH and redox potential (-0.75), pH and resistivity (-0.73), resistivity and total dissolved solids (-0.64), resistivity and conductivity (-0.57) and between resistivity and salinity (-0.57).

用理化参数比较研究了解两条淡水河- Me和Agneby -科特迪瓦的水质

本研究旨在比较科特迪瓦阿涅比河和梅河的物理化学参数。在Agneby河和Me河上调查的9个地点共确定了8个理化参数。在2015年8月至2016年7月期间按季节性频率进行采样。主成分分析(PCA)表明，与美河相比，阿涅比河地区水温较高(27.08±0.87°C)， pH值为中性(7.07±0.26)，盐度较高(0.05±0.04‰)，溶解物质含量较高(58.01±32.19 mg/L)，电阻率较低(26.97±22.46 kΩ/cm)。两河理化参数间的Bravais Pearson相关矩阵显示，盐度与电导率(0.89)、盐度(0.90)与TDS、电导率(0.91)与总溶解固形物呈极显著正相关，pH与氧化还原电位(-0.75)、pH与电阻率(-0.73)、电阻率与总溶解固形物(-0.64)呈高度负相关。电阻率和电导率(-0.57)，电阻率和盐度之间(-0.57)。
