TL;DR: USAEME is proposed as an efficient, fast, simple and non-expensive alternative to other extraction techniques such as SPE, SPME and LPME for the analysis of environmental waters including bottled, tap, river, municipal swimming pool, sewage and seaport water samples.

TL;DR: Sample preparation for phenol analysis using solid-phase extraction (SPE) is reviewed and the use, advantages and disadvantages of silica sorbents, polymeric, functionalized, carbon-based and mixed available sorbent, when applied to the separation and preconcentration of phenols are discussed.

TL;DR: Under optimal conditions, quantification limits between 1 and 3 ng/l were achieved for the determination of the considered estrogens in sewage water.

TL;DR: This study represents an advance in the use of photo-SPME to understand the photochemical fate of environmental organic pollutants and demonstrates its clear advantages with real samples.

TL;DR: It was confirmed by an activated sludge biodegradation batch test, where non-halogenated parabens had half-lives lower than 4 days, whereas halogenated derivatives of MeP turned out to be more persistent, with up to 10 days of half-life in the case of dihalogenations, and the QTOF system proved to be comparable to triple-quadrupole instruments in terms of quantitative capabilities.
