Evaluation of methods for the analysis of oxygen and carbon dioxide in water, sediment, litter, and soil

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 10, October 2026.
Abstract Choosing an appropriate analyzer to measure concentrations of oxygen (O2) and carbon dioxide (CO2) during biogeochemical cycling studies can be difficult, considering the range of options available. While several studies examine the abilities of specific analyzers, comparison of multiple analyzers and environmental sample types is lacking.

Carryover of Bracken Fern Toxins into Food, particularly into Water, Goat Milk and Goat Cheese from Swiss Alpine Farms

open access: yesFood Risk Assess Europe, Volume 4, Issue 4, October 2026.
Abstract In recent years there has been growing interest in bracken toxins, in understanding their effect, occurrence and prevention. Most of these substances are glycosides and are therefore highly water soluble and mobile. They can transfer to drinking water or via livestock to milk and meat, thereby potentially posing a health risk.
