<br/><br/> Dissolved and suspended parts of the trace metals (Ca, Cu, Pb, Zn, Cr, Ni, K, Mg, Na,  Fe, Mn, Al, As) along the Kuantan River Basin were investigated. The water samples  were collected from seven stations in July and November 2024, coinciding with the dry  and wet seasons. The concentrations of suspended and dissolved trace metals were  analyzed using Inductively Coupled Plasma Mass Spectrometry (ICP−MS). The average  concentrations of suspended Ca, Cu, Pb, Zn, Cr, Ni, K, Mg, Na, Fe, Mn, Al, As during  dry season were (ppb): 323±116, 12.2±8.91, 1.11±0.59, 13.3±5.74, 4920±7730,  2020±3150, 202±52.6, 299±133, 905±403, 25900±36500, 289±412, 680±595, 129±46.6,  respectively. Meanwhile, the concentrations of dissolved trace metals were (ppb):  12100±11800, 143±163, 0.12±0.14, 49.1±33.1, 1.59±2.76, 2.24±1.09, 3220±924,  3030±2660, 4860±3190, 189±161, 93.1±34.7, 29.5±16.1, 8.96±8.33, respectively. Also,  the average concentrations of suspended trace metals during wet season were (ppb):  428±31.9, 12.1±5.56, 2.42±0.83, 23.9±3.76, 23.3±1.16, 4.88±2.38, 357±77.9, 659±294,  955±88.7, 4590±1480, 20±8.78, 2180±840, 184±6.47, respectively. Meanwhile, the  average concentrations of dissolved trace metals were (ppb): 1320±743, 2.70±1.08,  1.90±2.60, 26.9±2.43, 0.17±0.23, 1.71±0.73, 1370±419, 1670±1390, 3070±2620,  37±23.3, 23.6±9.77, 33.4±12.8, 2.96±0.87, respectively. Besides, the impact of seasonal  changes on trace metal concentrations were considered in the study. The results revealed  that there were significant varies in the trace metal concentrations as the response to the  form of trace metals (suspended and dissolved), geographical location of the rivers and  seasonal differences. In summary, this study serves as a valuable reference on trace metal  concentrations in Kuantan River Basin
