Here, we provide a short overview of the state-of-the-art in activated carbon (AC) amendment to such sites. Most studies not only in sediments but also in soils were carried out in the laboratory and only a few in the field. Consequently, practical experience at the field scale is largely lacking, and feasible engineering approaches for AC amendment still need to be developed, especially for soils. The effectiveness of the AC treatment was evaluated by comparison of pollutant concentration reduction in the various endpoints with those in the unamended control matrix. Endpoints in use comprise pollutant concentrations in benthic organisms, depletive and non-depletive methods to quantify pollutant exposures, as well as various toxicity endpoints of plants. Half of the studies in soils and 68% of the studies in sediments showed reduced pollutant availabilities of >50% after AC amendment. Observed low reductions (<50%) might be due to low exposure time, insufficient equilibrium time for coke breeze, biochar, and granulated AC, overload of AC material, different uptake pathways of benthic organisms, and pollutant reductions outside the dynamic range of toxicity endpoints. Further research is needed to establish ideal AC amendment conditions to sediments and soils, leading to significantly reduced pollutant bioavailability. </p></abstract><publication_date><month>04</month><day>30</day><year>2013</year></publication_date><pages><first_page>305</first_page><last_page>317</last_page></pages><publisher_item><identifier id_type="pii">723</identifier></publisher_item><doi_data><doi>10.30955/gnj.000723</doi><timestamp>1713520102</timestamp><resource>https://journal.gnest.org/publication/723</resource></doi_data></journal_article></journal></body></doi_batch> </div>
