Analysis of the impact of organic pollutants on marine microbial communities
Increasing amounts of organic synthetic chemicals are currently emitted to the environment by human activities. The more recalcitrant fraction of this pollutant mixture reaches marine ecosystems mainly through rivers, continental run-off, and diffuse atmospheric inputs. Once in seawater, it represen...

Increasing amounts of organic synthetic chemicals are currently emitted to the environment by human activities. The more recalcitrant fraction of this pollutant mixture reaches marine ecosystems mainly through rivers, continental run-off, and diffuse atmospheric inputs. Once in seawater, it represents the anthropogenic fraction of the dissolved organic carbon (ADOC) pool. However, the total amount of ADOC is unknown, while its effects to ecosystems and detailed composition is largely unknown. Over the past decades, the scientific research effort has focused on the effects of organic pollutants (OPs) in marine biota, especially in oil spills events or under toxicological testing in laboratories, neglecting the importance of the chronic pollution perturbation of the biosphere composition caused by diffusive inputs of large number of pollutants at low concentrations.
