Plutonium isotopes activity and selected heavy metal concentration in sediment samples from three Lublin rivers are presented. Average values of ^239,240Pu radioactivity is equal to 0.050 +/- 0.034 Bq/kg dry weight, and ²³⁸Pu 0.005 +/- 0.005 Bq/kg. These values are about 4-times lower those that found in soils from Lublin region. A close correlation between plutonium and calcium concentrations was observed (r = 0.97), but between plutonium and organic matter this was rather poor (r = 0.63). River sediment contamination with heavy metals: Mn, Zn, Pb, Cu and Ba does not exceed the permissible concentration limit in sewage sludge introduced to soil. Mean values of metal concentrations found are: 242 ppm Mn, 313 ppm Zn, 95 ppm Pb, 72 ppm Cu and 274 ppm Ba. Samples collected from the same points after a 4-year period do not reveal large differences in comparison with old ones.
