Abstract: This study is aimed at seasonal measurement of trace metals and physicochemical parameters of River Amba, Nasarawa State, North Central, Nigeria. The water data were collected during 2019 to 2020 from 3 sampling points distributed along the river. The physicochemical parameters analysed are pH, alkalinity, temperature, BOD, COD, conductivity and TDS. While, the trace metals in Mg/L are Pb, Cd, Zn, Mn, Fe and Cr. Trace metals during dry season ranges from 0.55 to 0.64, 0.41 to 0.45, 2.00 to 2.02, 0.20 to 0.22, 0.48 to 0.50 and 0.17 to 0.19 respectively. While during wet season, it ranges from 0.65 to 0.72, 0.55 to 0.65, 2.03 to 2.05, 0.22 to 0.25, 0.50 to 0.57 and 0.30 to 0.33 in that order. the result revealed that the mean concentrations of trace metals were above the permissive WHO/EU standards except for Mn and Zn in all the water samples irrespective of the season. Consequently, the physicochemical parameters analysed during wet and dry season are within the WHO recommended standard with exception of COD and BOD. The results indicate that seasonal change did not bring significant alteration in the parameters analyzed. In order to reduce the trace metals, laws should be enacted by the Governments to regulate the activities that take place in the river.
