Effects of particulate matter (PM) loading on riffle bed quality were studied in small boreal streams in northern Finland. Peat mining increased the amount of particulate organic matter (POM) on riffle beds. POM consisted mainly of small particles, of diameter less than 1 mm. The finest PM particles, of diameter less than 0.075 mm, were shown to carry Fe, and there was a positive relationship between PM loading and the amount of Fe on the riffle beds. The results indicate that loading with fine-grained POM and the increase in the amount of Fe attached to finest PM particles may be a cause of the changes observed in benthic invertebrate and fish communities in riffles affected by peat mining.
