Soil is regarded as a natural repository for strongly adsorbed pollutants since glyphosate (GLY) is preferentially adsorbed by the inorganic fraction of the soil, which may greatly limits its leaching. In this way, understanding how clay mineralogy influences the sorption and transport processes of glyphosate in soils with different mineralogical characteristics is highly relevant. In this work, two clay mineralogy contrasting soils were used to evaluate GLY retention: a Oxisol (OX) with high levels of iron oxides (amorphous and crystalline) and a Inceptisol (IN) with a predominance of kaolinite.

Doping with meclofenoxate, a nootropic stimulant prohibited in-competition by the World Anti-Doping Agency (WADA), is identified through the primary marker of urinary 4-chlorophenoxyacetic acid (4-CPA). However, the presence of 4-CPA can also arise from permissible sources. This study ventured into comparing urinary excretion patterns among exposures to permitted chemicals (chlorphenesin and 4-CPA) and the banned stimulant (meclofenoxate) and interpreting the analytical findings according to the reporting requirements.

Glyphosate (Gly) is a widely-used herbicide in food production, while, the residue of which due to the long-term and excessive overspray poses serious threats to public health. The development of reliable methods for its sensitive detection is of great urgency. In this study, a novel ratiometric fluorescent nanosensor by encapsulating N-doped carbon dots (N-CDs) and gold nanoclusters (AuNCs) in zeolitic imidazole framework-8 (ZIF-8) as the dual-emissive fluorescence probes at 410 and 650 nm, respectively, was constructed for Gly detection.
