Relative abundance of atropisomer pairs in metolachlor metabolites, MESA and MOXA, vary with slope and hydric soils in subwatersheds of the Choptank River watershed, Maryland.

Metolachlor is the most heavily used member of acetanilide herbicides, which are noted for forming highly soluble metabolites in root zone soils soon after field application. The two primary metabolites of metolachlor, metolachlor ethane sulfonic acid (MESA) and metolachlor oxanilic acid (MOXA), retain the same chiral chemistry as their source and are important tracers of nitrate loading from agricultural cropland. New analytical methods for separating the isomers of MESA and MOXA, enable studies assessing changes in the abundance of atropisomer pairs of the carbon chiral enantiomers in environmental samples.

Carbapenemase-producing Enterobacterales are pathogens classified as a critical priority by the World Health Organization and a burden on human health worldwide. IMI, NmcA, and FRI are under-detected class A carbapenemases that have been reported in the human, animal and environmental compartments, particularly these last 5 years. Bacteria producing these carbapenemases have been mostly identified in digestive carriage screenings, but they are also involved in severe infections, such as bacteremia.

Flooding remains a critical issue in urban catchments, driven by complex interactions between land use changes, hydrological dynamics, and environmental factors. This study aims to investigate how modifications in Landscape Hydric Potential (LHP) affect flood behavior in the Drwinka River catchment in Krakow, Poland. Given the rapid urbanization and its impacts on hydrological systems, understanding these changes is essential for effective flood management and mitigation.

In plantations, coppice rotations often yield less than initial rotations. The TECHS project (Tolerance of Clones to Hydric, Thermal and Biotic Stresses) studied short rotation coppicing across a 3000 km gradient. The main objective of this work was to compare the survival, sprouting, and initial growth of clones managed and to examine factors that might influence the productivity of the coppice rotation: climate, genotypes, and stocking.

Climate change impacts the Mediterranean region, transforming it from region with a semi-arid climate to a region with an arid climate. Under this situation, while groundwater is an essential hydric resource, its existence is in danger due to anthropogenic pressures. Persistent mobile organic compounds (PMOCs) have recently been recognised as an emerging problem; however, PMOCs in groundwater need to be better characterised.
