Microbial 2,4,6-trinitrotoluene degradation: could we learn from (bio)chemistry for bioremediation and vice versa?
Ben Stenuit,Spiros N. Agathos +1 more
TL;DR: The deciphering of the physiological roles of promiscuous enzymes involved in TNT biodegradation, such as type II hydride transferases of the Old Yellow Enzyme family, opens new perspectives for bioremediation.

Environmental risk assessment of three selective serotonin reuptake inhibitors in the aquatic environment: A case study including a cocktail scenario
TL;DR: The results indicate that the concentrations in the wastewater effluents are one to two orders of magnitude lower than the concentrations likely to cause an effect in the aquatic biota.

Partition coefficients and interfacial activity for polar components in oil/water model systems
TL;DR: Partition coefficients, surface tension, and interfacial tension for some polar organic components dissolved in oil/water model systems have been investigated and it is indicated that the aqueous phase is the one that governs the interfacial pressure.

Adsorption and biodegradation of antidiabetic pharmaceuticals in soils.
TL;DR: Adsorption and biodegradation of four antidiabetic pharmaceuticals - glimepiride, glibenclamide, gliclazide and metformin - were examined in three natural soils and indicate that none of the tested drugs can be classified as quickly biodegradable.

Solute transport model for trace organic neutral and charged compounds through nanofiltration and reverse osmosis membranes.
TL;DR: A membrane transport model to account for diffusive and convective contributions to solute transport and rejection is developed and shown to be dominant for most compounds, but diffusion is important for more hydrophobic non-polar compounds.
