In this study we present the petrographical features of seven sediment samples obtained from aquatic environments in Sweden, Finland and The Netherlands. Most of the samples represent the uppermost layers, which accumulated during the recent past. Their total organic carbon content ranges between 1.5 and 20%. Density separations using heavy liquids were applied, in order to concentrate the organic matter and thus to facilitate the petrographical determinations. The microscopic approach revealed significant variations in the origin and hence, the type of the contained organic matter. Apart from modern plant debris and the algae indicating water-logged conditions, several particles of naturally and artificially derived solid-organic material were identified. The latter constitute organic contaminants, and include unburnt residues of highrank coals and chars. The petrographic data show a significant comparability with the ‘black carbon’ data determined by chemo-thermal oxidation at 375°C, demonstrating the applicability of the microscopic analysis in environmental studies. </p></abstract><publication_date><month>04</month><day>29</day><year>2013</year></publication_date><pages><first_page>137</first_page><last_page>143</last_page></pages><publisher_item><identifier id_type="pii">425</identifier></publisher_item><doi_data><doi>10.30955/gnj.000425</doi><timestamp>1714154627</timestamp><resource>https://journal.gnest.org/publication/425</resource></doi_data></journal_article></journal></body></doi_batch> </div>
