Description Results of the present study indicate that sediments from Lake Pilnok contain a large portion of dioxin-like, estrogenic and anti-androgenic compounds, which stimulated fecundity in G. fossarum. Although some effects might be attributed to PAHs, most of the bioactive compounds could not be detected by traditional instrumental analyses. Possibly, bioavailable fractions of the maceral (solid coal mass rich in organic compounds) could have contributed to the observed activities but only few studies investigated its biological effects and it will require further research. The present study emphasizes the need for integrated assessment of contaminated sediments to elucidate their ecotoxicological impacts.
