Organic pollutants (OPs) are potentially present in composts and the assessment of their content and bioaccessibility in these composts is of paramount importance. In this work, we proposed a model to simulate the behavior of OPs and the dynamic of organic C during composting. This model, named COP-Compost, includes two modules. An existing organic C module is based on the biochemical compositi...

A flow immunoassay based on a combined technique of the sequential injection with the beads injection using magnetic microbeads immobilized with antigen or antibody is described. A methodology of the present immunoassay based on chemiluminescence and electrochemical detection and its application to the determination of vitelloginin (Vg) and anionic surfactant, linear alkylbenzene sulfonate (LAS...

The effect of the presence of a surfactant on the activity of a mixture of environmental estrogens was assessed. In their natural habitat, fish are subject not only to exposure to mixtures of estrogenic compounds, as has been addressed in previous publications, but also to other confounding factors (chemical, physical and biological), which may, in theory, affect their responses to such compoun...

The low flow characteristics of heavy oil have brought many challenges to its exploitation. Looking for a cost-effective crude improver reduce the viscosity is currently most important challenge. Small-molecule improvers meet above requirements and become an ideal target oilfield production. In this article, three kinds barium salts alkylbenzene sulfonates with different lengths alkyl chains we...

Cation-exchange resins are used in the management of hyperkalemia, particularly in patients with end-stage renal disease. These resins were associated with gastrointestinal tract lesions, especially sodium polystyrene sulfonate (Kayexalate) mixed with sorbitol. We present a case of colonic necrosis after the administration of calcium polystyrene sulfonate (Kalimate) not suspended in sorbitol.

The fungal genus Exophiala comprises both pathogen species, which cause severe infections in humans, and environmental species, which are able to degrade alkylbenzene compounds. The draft genome sequence of Exophiala mesophila presented here is the first genome assembly of an alkylbenzene-degrading organism belonging to the genus Exophiala.
