Hold My Beer: The Linkage between Municipal Water and Brewing Location on PFAS in Popular Beverages

This study investigated the presence of PFAS in 23 different beers purchased in North Carolina and found detectable levels in most samples. The PFAS levels in beer were correlated with PFAS concentrations in the municipal water used for brewing, suggesting that contaminated drinking water is a primary source of PFAS in beer. The study also found variability in PFAS levels between different cans of the same beer.

Scientists' Warning to Humanity: Rapid degradation of the world's large lakes

Large lakes around the world are rapidly degrading due to a combination of long-term human impacts and emerging stressors like climate change and microplastic pollution. This degradation threatens essential ecosystem services and requires urgent, multi-faceted conservation efforts to protect these vital resources.

Complementary green analytical procedure index (ComplexGAPI) and software

This paper introduces ComplexGAPI, an extension of the Green Analytical Procedure Index (GAPI), to assess the environmental impact of the entire analytical process, including pre-analytical steps like reagent synthesis. The tool uses a hexagonal pictogram and color-coding to represent different factors, along with software to facilitate its application.

Fertilizers and nitrate pollution of surface and ground water: an increasingly pervasive global problem

Fertilizer use in agriculture is a major driver of nitrate pollution in surface and ground waters worldwide. Improving crop and fertilizer management practices, including optimizing fertilizer rates and timing, adopting appropriate irrigation strategies, and implementing structural adjustments in agriculture, can significantly reduce nitrate leaching and mitigate water pollution.

Phenological shifts in lake stratification under climate change

Lakes across the Northern Hemisphere are stratifying earlier and for longer periods, which may increase the risk of severe ecological changes. By 2070-2099 under high greenhouse-gas-emission scenarios, stratification will begin 22 days earlier and end 11 days later, a prolongation that could accelerate lake deoxygenation and release phosphorus from sediments.
