This study aimed to demonstrate how quickly sediments can move in the urban environment carrying concentrations of trace elements adsorbed. To achieve this goal, the concentration of trace elements (Zn, Cr, Ni, Cu, and Pb) in the street and river sediments were determined in two micro‐hydrographic basins of Toledo city in the state of Paraná, Brazil. The methodology used suitable equipment for the sediments collected, and the analytical determination was performed only with sediments fractions smaller than 63 μm by inductively coupled plasma optical emission spectrometry. The results of trace element concentrations were submitted to a correlational statistical analysis, evaluating the rainfall influence in the movement of these sediments. The study concluded that trace elements are adsorbed by street's sediments and quickly carried by surface flow to the rivers that drain these areas. This process was facilitated by waterproofed surfaces. Therefore, the study showed that monitoring must be systematic to observe the mobility of trace elements in urban environments.
