Abstract:Abstract:This study aimed to determine the granulometric and mineralogical composition and the Cr, Ni and Pb trace element content in sediments collected from impermeable streets located in the urban perimeter of Toledo, PR, Brazil. The mineralogical analyses were performed by a diffractometer, the granulometric analyses by integrated sieving methods and laser diffraction, and the analyses of the trace elements in quartered fractions of the sediments were carried out by optical emission spectrometry with induc… Show more
