Fate of β-blocker human pharmaceuticals in surface water: Comparison of measured and simulated concentrations in the Glatt Valley Watershed, Switzerland
Alfredo C. Alder,Christian Schaffner,Marius Majewsky,Jörg Klasmeier,Kathrin Fenner,Kathrin Fenner +5 more
TL;DR: Modelling might be sufficient to estimate daily average exposure concentrations for compounds that are either recalcitrant or whose degradation and sorption behaviour can be predicted with confidence based on laboratory experiments, and chemical measurements should be reserved for assessing point sources.

Influence of Different Electron Donors and Acceptors on Dehalorespiration of Tetrachloroethene by Desulfitobacterium frappieri TCE1
Jan Gerritse,Oliver Drzyzga,Geert Kloetstra,Mischa Keijmel,Luit P. Wiersum,Roger A. Hutson,Matthew D. Collins,Jan C. Gottschal +7 more
TL;DR: The growth yields of the newly isolated bacterium when PCE is the electron acceptor are similar to those obtained for other dehalorespiring anaerobes and the maximum specific reductive dechlorination rates are 4 to 16 times higher.

The behaviour of pharmaceuticals and heavy metals during struvite precipitation in urine
TL;DR: Phosphate recovery from urine over struvite precipitation is shown to render a product free from most organic micropollutants and containing only a fraction of the already low amounts of heavy metals in urine.

The Degradation of Organophosphorus Pesticides in Natural Waters: A Critical Review
Simo O. Pehkonen,Qi Zhang +1 more
TL;DR: In this article, the authors discuss the fate of organophosphorus pesticides in the aquatic environment via processes such as adsorption, hydrolysis, oxidation, and photochemical degradation.

Mineral Matrices and Organic Matter
TL;DR: In this paper, the authors review lab and field experimentation within the soil and sediment literature in order to provide a synoptic view of the manners in which organic and mineral interact, with emphasis on the role organic-mineral interactions play in preserving organic matter in the environment.
