Nowadays, a range of anthropogenic perturbances affects marine and inland-water ecosystems mainly due to the accumulation of pollutants in the water column and sediments. Microbial communities, consisted of viruses up to micro-eukaryotes, are constantly exposed to chemical alterations in the water and sediment characteristics, while they also are capable to tolerate, transform or transfer the pollutants within the trophic webs.
This special session welcomes oral and poster presentations that focus on the broad field of microbial ecotoxicology, i.e. the study of microbial communities under the “stress” of toxic compounds released via human activities. Metals, metal oxides, nanomaterials, micro- and nano- plastics, organic pollutants, hydrocarbons, contaminants of emerging concern, antibiotics, pesticides and other hazardous materials may be the target of the ecotoxicological assay, either as part of a monitoring project or a smaller-scale survey. Both studies in the field (offshore, coastal zone, raptorial zone, lagoons, inland waters, deep and shallow sediments and water-column) and in the laboratory (mono- or poly- culture, micro- or mesocosms, short or long incubation) will be discussed. Ecotoxicity in the level of a single cell, a population or the total community and the responses (e.g. tolerance, adaptation, resilience) studied using –omics technologies ([meta]genomics, [meta]transcriptomics, [meta]proteomics, metabolomics) in combination with classical tools (morphology, abundance, productivity) and further biotechnological applications (e.g. bioremediation) will provide us novel insights into the nature of the changing oceans and the associated consequences in ecosystem sustainability and management.
