Eichhornia crassipies were used to investigate the seasonal variation of heavy metal contamination levels in the Aba River in Abia State, Nigeria. The presence of Macrophytes in rivers is frequently a strong indicator of heavy metal accumulation in water bodies. To cover the Nigerian rainy season and the Harmattan season, bi-monthly sampling was carried out. At the UST, PZA, ABT, and DST sampling points, iron (Fe) was more abundant, with a maximum concentration of 69.5 mg/kg in December/January. The lowest iron concentrations were found in UST and DST in April/May, and in PZA and ABT in October/November. Manganese concentrations at PZA and NBL peaked at 7 mg/kg during the dry season in October and November. The lowest concentrations were found in the Harmattan seasons of December/January at UST, PZA, and ABT. The varied concentrations of zinc (Zn) showed no pattern or trend except for a value of 9.7 mg/kg in October/November of ABT, whereas lead (Pb) metal was significantly identified in February/March (end of Harmattan) and April/May. During the seasonal study, (the start of the rains) During the months of June and July, chromium metal (Cr) was uniformly distributed but significant at NBL. Nickel (Ni) metal was found in trace amounts in the UST, PZA, and NBL. Copper was mostly detected during the rainy seasons of April/May and June/July, albeit at low levels compared to other metals. As a result, the most active level of heavy metals was found in the UST and PZA sampling points, while the phytochemical activity of heavy metals was highest during the Harmattan season. As a result, metal removal in Eichhornia crassipes occurred in the following order: Fe > Mn> Cr > Ni > Pb > Zn > Cd.
