Abstract Key roles of marine dimethyl sulfoniopropionate (DMSP), dimethyl sulfide (DMS), methyl mercaptan (MeSH), and carbon disulfide (CS2) in the sulfur cycle and/or atmospheric chemistry, alongside the rapid environme...

Abstract This study examines the influence of divisor selection on the efficacy of advanced analytical spectrophotometric methods that integrate artificial intelligence (AI), green-chemistry principles, and white-analyti...

This review article points out, through an overview, aspects that are related to the procedures established by green analytical chemistry, for the extraction of bioactive compounds in plants, through the use of assisted ...

Ecotoxicology is the study of the effects and fate of contaminant substances on ecosystems. It aims to determine if there is an ecological risk by comparing the concentration that produces toxic effects with the environm...

Managing plastic waste is still a big environmental problem, especially in schools where students need to learn to care about the environment from a young age. This study investigates the execution of a zero waste-orient...

Selenium (Se) is required at a fundamental physiological level in all animals. Adequate levels of Se are necessary for proper bone metabolism, iodine metabolism, immune function, reproductive success, and recruitment. Se...

Anions are ionic species that play important roles in biology, medicine, catalysis, and environmental science. Identifying these species is crucial for industrial applications and clinical diagnostics. In recent years, e...

A novel centrifuge-less cloud point extraction (CL-CPE) method was developed for the spectrophotometric determination of copper(II) using 4-nitrocatechol (4NC) as the chelating agent. The extraction system utilizes a mix...

ABSTRACT Phthalates such as isophthalate, phthalate, and terephthalate are widespread environmental pollutants with significant health and ecological impacts. Comamonas testosteroni KF1 initiates isophthalate degradation...
