TL;DR: The marine calanoid copepod Acartia tonsa was exposed to methyltestosterone, letrozole, MET and fenarimol for 21 d, showing effects on gonads caused rather by disturbance of endocrine signalling or interference with hormone metabolism than by general toxicity.

TL;DR: Four different miniaturized methodologies were developed and applied to the analysis of 11 UV filters in sand samples, based on ultrasound and vortex extractions, on-column lixiviation, and ultrasound extraction followed by solid-phase microextraction, and the results were statistically compared performing an analysis of variance.
Abstract: Four different miniaturized methodologies were developed and applied to the analysis of 11 UV filters in sand samples. These approaches were based on ultrasound and vortex extractions, on-column lixiviation, and ultrasound extraction followed by solid-phase microextraction. Gas chromatography with tandem mass spectrometry was used for quantitative analysis. The analytical performance provided by the four methods was evaluated in terms of linearity, accuracy, precision, and limits of quantification. Lixiviation was discarded since it provided the lowest recoveries and the highest limits of quantification. In contrast, ultrasound and vortex extractions, and ultrasound extraction followed by solid-phase microextraction were suitable, with recoveries in general >85% and limits of quantification at the low ng/g level. Moreover, ultrasound extraction followed by solid-phase microextraction allowed using external calibration with aqueous standards and it provided higher sensitivity, with limits of quantification in general one order of magnitude lower than those achieved with the other techniques. The methodologies were applied for the analysis of four marine sand samples, and the results were statistically compared performing an analysis of variance. Eight out of the eleven target UV filters were detected. Octocrylene was found at very high concentrations (up to 1000 ng/g) followed by ethylhexyl salicylate, 4-methylbenzylidene camphor, homosalate, and 2-ethylhexyl methoxycinnamate.

TL;DR: In this article, an ultrasound-assisted emulsification-microextraction (USAEME) was used for the analysis in waters of 2-phenylphenol (PP), 4-tert-butylphenols (TBP), benzothiazole (BTZ) and piperonyl butoxide (PBO), belonging to different chemical families, and all of them characterized by its high production volume.
Abstract: Ultrasound-assisted emulsification–microextraction (USAEME) demonstrated its applicability for the analysis in waters of 2-phenylphenol (PP), 4-tert-butylphenol (TBP), benzothiazole (BTZ) and piperonyl butoxide (PBO), belonging to different chemical families, and all of them characterised by its high production volume. In the developed USAEME procedure, compounds were extracted in chloroform from 10 mL of water sample during only 5 min. The addition of derivatising reagents has been studied as part of the optimisation process. The optimised procedure provided an efficient and exhaustive extraction with the advantage that the extract was ready for GC analysis. The method was validated using real environmental water samples, obtaining recoveries between 68 and 111%, RSD values ≤10%, and limits of quantification at the sub-ng per millilitre level (0.004–0.072 μg L−1). The application of the method to the determination of the targets in different environmental waters showed their presence in most samples.In a...

TL;DR: In this article, a simple numerical method for computing a conformal map from a domain exterior to a smooth Jordan curve in the complex plane onto the exterior of the unit disk is described, based on a boundary integral equation similar to the Kerzman-Stein integral equation for interior mappings.
Abstract: A simple numerical method is described for computing a conformal map from a domain exterior to a smooth Jordan curve in the complex plane onto the exterior of the unit disk. The numerical method is based on a boundary integral equation similar to the Kerzman-Stein integral equation for interior mappings. Typical examples show that numerical results of high accuracy can be obtained provided that the boundaries are smooth
