Suspended solids found in porewaters obtained in waterlogged soil sequences that included representative laterite-podzol transitions, associated brooks and major rivers of the Rio Negro watershed (Brazil) were studied using electron paramagnetic resonance (EPR) and Fourier-transform infrared spectroscopies. The main goal was to ascertain sources and track the evolution of suspended matter using a ubiquitous chemical species, FeIII complexed to organic matter (FeOM). Three size fractions were separated by tangential-flow (ultra)filtration: particulate (>0.2 mu m), dense (P) and light (Ps), and colloidal (5 kD
