TL;DR: Two methods to assess humic acids (HAs) in surface water namely absorbance of ultraviolet light at 254 nm (UV(254)) and total organic carbon (TOC) are compared as well as to evaluate the effects of calcium and magnesium concentrations, pH and sample filtration on the methods' results.

TL;DR: The phosphorus distribution in volcanic sediments of three lakes that are under different anthropogenic pressures in São Miguel island was evaluated using a sequential extraction scheme and the results show that in lakes with higher trophic status (Lake Furnas and Lake Sete Cidades), the NaOH extracted P is the dominant fraction, that contribute with more than 50% to total sedimentary phosphorus.

TL;DR: The present study used a LCA approach for comparing alternative wastewater treatment processes for small and decentralised rural communities and found the low environmental impact of the energy-saving wastewater treatment plants was demonstrated.

TL;DR: A BOD biosensor based on the microbial fuel cell principle was tested for online and in situ monitoring of biodegradable organic content of domestic wastewater and provides useful information for the development of a biosensor for real-time in situ Monitoring of wastewater quality.

TL;DR: In this article, the authors present some key points on design and operation in wastewater treatment of brewery and winery industries, including an introduction of the industrial processes and then wastewater characteristics and treatment processes.
