Concentrations and mass fluxes of chloroacetic acids and trifluoroacetic acid in rain and natural waters in Switzerland

Article Abstract:

Researchers from the Swiss Federal Institute for Environmental Science and Technology and the Swiss Federal Institute of Technology established the mass balances of haloacetic acids in Switzerland. Rain, surface water, groundwater, and waste water were measured for the mass fluxes and levels of haloacetic acids.

Uptake and elimination of triorganotin compounds by larval midge Chironomus riparius in the absence and presence of aldrich humic acid

Article Abstract:

In this study, the uptake and elimination of triorganotin compounds by larval midge Chironomus riparius in sediments was researched in the absence and presence of aldrich humic acid. The study is broken down into an introduction, a discussion of the experiment and its results. Various tables and graphs accompany the article.

Sorption and desorption behavior of organotin compounds in sediment-pore water systems

Article Abstract:

Sediment and water samples from contaminated freshwater harbors at Lake Zurich and Lake Constance are tested for levels of organotin compounds, in particular triphenyltin and tributyltin. The sorption and desorption behaviors of these contaminents is studied, including their degradation products.
