Rivers are one of the most important waterbodies depended on by the whole environment for their daily lives. But now a days, water-related incidents are increasing much more because of the improper lifestyle of human beings. Trace metals are one of the main causes of the contamination of water. The present study deals with the analysis of five trace metals using Atomic Absorption Spectrophotometer at five selected sites in Neyyar River. The study period is from March 2022 to February 2023. According to rainfall the study period was portioned into three main seasons, monsoon (March 2022 to June 2022), post monsoon (July 2022 to October 2022) and pre monsoon (November 2022 to February 2023). Trace metals such as nickel, zinc, copper, iron, and manganese were selected for this study. Statistical analysis was done by the help of Two-way analysis of variance (ANOVA). It shows variation in some parameters. The water in the Neyyar River is in good condition.

Keywords: Neyyar River, trace metals, ANOVA, significance
