Metabolism of imidacloprid and DDT by P450 CYP6G1 expressed in cell cultures of Nicotiana tabacum suggests detoxification of these insecticides in Cyp6g1-overexpressing strains of Drosophila melanogaster, leading to resistance.
TL;DR: The gap between the supposed resistance gene Cyp6g1 and the observed resistance phenomenon was closed by the evidence that CYP6G1 is capable of metabolising at least two insecticides.

Fate in soil of 14C-sulfadiazine residues contained in the manure of young pigs treated with a veterinary antibiotic
Burkhard Schmidt,Jürgen Ebert,Marc Lamshöft,Brigitte Thiede,Ramona Schumacher-Buffel,Rong Ji,Philippe F.-X. Corvini,Andreas Schäffer +7 more
TL;DR: Non-extractable residues were the main route of the fate of the 14C-SDZ residues, and were stable and not remobilized throughout 218 days of incubation, and appeared to be due to stable covalent binding to soil organic matter.

In search for the ecological and toxicological relevance of sediment re-mobilisation and transport during flood events.

TL;DR: In this article, the authors combine methodologies of hydraulic engineering and ecotoxicology in a new interdisciplinary approach to assess the risks associated with the re-mobilisation of particulate bound contaminants often observed after severe flood events.

Synthesis of branched para-nonylphenol isomers: occurrence and quantification in two commercial mixtures.
TL;DR: Eight tertiary nonanols were synthesized via Grignard reaction and coupled by Friedel-Crafts alkylation with phenol to the corresponding nonylphenols and analyses revealed that all obtained isomers are occurring in different quantities in both commercial NP mixtures.

From humic substances to soil organic matter-microbial contributions. In honour of Konrad Haider and James P. Martin for their outstanding research contribution to soil science
TL;DR: In this article, the authors discuss the key experiments of Martin and Haider in this field and related follow-up research finally resulting in the current view on formation mechanisms of SOM and non-extractable residues (NER) of xenobiotics.
