TL;DR: In this paper, a laboratory protocol that simulates the exposure of plastic floating in the marine environment to ultraviolet light (UV) and nontarget analysis to identify degradation products of plastic polymers in water was developed.

TL;DR: All plastic leachates activated the oxidative stress response, in most cases with increased induction by UV-treated samples compared to dark controls, and polyethylene-specific effects were partially explained by the detected dicarboxylic acids.

TL;DR: A combined method for quantitative analysis, along with suspect and non-target screening of per- and polyfluoroalkyl substances (PFAS) was developed using ultra-high pressure liquid chromatography-ultra-high resolution (Orbitrap) mass spectrometry, which revealed the presence of perfluoro-4-ethylcyclohexanesulfonate (PFECHS), which displayed declining trends since the year 2000.

TL;DR: A method based on ultra performance liquid chromatography coupled to tandem mass spectrometry (UPLC/MS/MS) was developed and optimized for the analysis of mono-, di-, and triPAPs, including a clean-up step for the raw extracts, and detected in all food packaging materials obtained from the Swedish market.

TL;DR: In this paper, the authors compared three analytical techniques for total fluorine determination: combustion ion chromatography (CIC), particle-induced γ-ray emission spectroscopy (PIGE), and instrumental neutron activation analysis (INAA).
