“…We also note that large volumes of chemical dispersants were cast into the Gulf of Mexico to treat the Deepwater Horizon crude oil spill (Lehr et al, 2010). Therefore, much research has been focused on the sources, transport, fates, toxicity, and impact of dispersants in different environmental media, including the atmosphere, on marine sediments (Roslan et al, 2010;Cantarero et al, 2012;Almeda et al, 2014;Passow, 2016). However, the impact of surfactants on the marine carbon cycle and the sinking particles is largely unexplored.…”

“…After use, these surfactants are typically discharged into rivers or sewage treatment plants and eventually enter the coastal and open oceans (Ying, 2006). Recent studies have now recorded their presence at various concentrations in environmental media such as wastewater, seawater, suspended solids, and sediments (Clara et al, 2007;Cantarero et al, 2012;Huang et al, 2015). Therefore, the assessment of surfactant effects on the spontaneous assembly of DOC polymers and existing microgels requires a determination of which types of these materials might have adverse effects on organic carbon conversion.…”

The possible impact of three types of anthropogenic surfactants on the ability of marine dissolved organic carbon (DOC) to form self-assembled microgels was evaluated. The behavior of existing native microgels was also examined in the presence of surfactants. These results reveal that the release of surfactants even at low concentrations into the aquatic environment could effectively hinder the self-assembly of DOC polymers. The extent of the size reduction had the following order: anionic, cationic, and non-ionic. Furthermore, charged surfactants can disrupt existing native microgels, converting large assemblies into smaller particles. One possible mechanisms is that surfactants are able to enhance the stability of DOC polymers and disrupt aggregates due to their surface charges and protein-denaturing activities. These findings suggest that the ecological system is altered by anthropogenic surfactants, and provide useful information for ecological assessments of different types of surfactants and raise warnings about surfactant applications.

“…The amount of marine sediment monitoring data found, from highest to lowest, was AE > LAS > DTDMAC > AES > AS ( Table 1). Detected concentrations ranged from 0.0074 mg/kg to 9.19 mg/kg in AE [30], <0.003 mg/kg to 15.63 mg/kg in LAS [13,21,30,31], 0.0048 mg/kg to >25 mg/kg in DTDMAC [30], 0.061 mg/kg to 14.32 mg/kg in AES [21,[32][33][34], and 0.13 mg/kg in AS [21]. Measured concentrations in sediment were higher when sampling was undertaken in close proximity to direct discharge from sewage-treatment plant effluents, whereas samples taken from offshore locations were not impacted by direct discharge and consequently showed much lower surfactant concentration levels.…”

Surfactants are a commercially important group of chemicals widely used on a global scale. Despite high removal efficiencies during wastewater treatment, their high consumption volumes mean that a certain fraction will always enter aquatic ecosystems, with marine environments being the ultimate sites of deposition. Consequently, surfactants have been detected within marine waters and sediments. However, aquatic environmental studies have mostly focused on the freshwater environment, and marine studies are considerably underrepresented by comparison. The present review aims to provide a summary of current marine environmental fate (monitoring, biodegradation, and bioconcentration) and effects data of 5 key surfactant groups: linear alkylbenzene sulfonates, alcohol ethoxysulfates, alkyl sulfates, alcohol ethoxylates, and ditallow dimethyl ammonium chloride. Monitoring data are currently limited, especially for alcohol ethoxysulfates and alkyl sulfates. Biodegradation was shown to be considerably slower under marine conditions, whereas ecotoxicity studies suggest that marine species are approximately equally as sensitive to these surfactants as freshwater species. Marine bioconcentration studies are almost nonexistent. Current gaps within the literature are presented, thereby highlighting research areas where additional marine studies should focus.

Ergene Basin is one of the most important industrial centers due to the geographical location in Turkey. Uncontrolled and rapidly increasing industrialization brings together a large number of environmental problems in the basin. In this study, pollution was investigated in the water samples taken at time intervals and different parts of groundwater and surface water resources located within Ergene Basin by methylene blue anionic surfactants (MBAS) analysis method. Turbidity, temperature, pH, electrical conductivity (EC), concentrations of total P and linear alkylbenzene sulfonates (LAS) were simultaneously determined in the investigated water resources. The results were compared with the Turkish Water Pollution Control Regulation specified in the Quality Criteria of the Inland Water Resources according to their class. The total P and LAS concentrations of surface waters are generally higher than groundwater. In terms of LAS concentrations, the groundwater is I-II class and the surface water is II-IV class.
