Polychlorinated Biphenyl Sorption and Availability in Field-Contaminated Sediments
TL;DR: Traditional and new relationships of polychlorinated biphenyl (PCB) distribution among the solid phases, the free aqueous phase, and biolipids are comprehensively reviewed using seven well-characterized freshwater and marine sediments polluted with PCBs.
Journal ArticleDOI
Organic carbon normalisation of PCB, PAH and pesticide concentrations in suspended solids
TL;DR: In this paper, it was found that the aging of organic matter during settling in the water column or after burial in sediments, may cause the increased fixation of HOCs onto organic particles.

Comparison of nutrient and contaminant fluxes in two areas with different hydrological regimes (Empordà Wetlands, NE Spain)
Rocío López-Flores,Xavier D. Quintana,Victòria Salvadó,Manuela Hidalgo,Lluís Sala,Ramon Moreno-Amich +5 more
TL;DR: The confined waters of BWM showed higher sensitivity to contaminant input loadings than FWM due to the lack of continuous water outputs, and the importance of confinement and its effect on pollutant concentrations must be borne in mind to achieve correct management of Mediterranean wetlands.

Sorption of imidazolium-based ionic liquids to aquatic sediments.
TL;DR: It is concluded that aquatic sediments have a limited capacity to sorb alkylmethylimidazolium ILs and that the transport of these contaminants in aquatic systems will not be strongly attenuated by sediments.

Enzymes for enhancing bioremediation of petroleum-contaminated soils: a brief review.
Chi-Yuan Fan,S. Krishnamurthy +1 more
TL;DR: This paper examines the biological treatment technology for cleaning up petroleum product-contaminated soils, with special emphasis on microbial enzyme systems for enhancing the rate of biodegradation of petroleum hydrocarbons.
