Abstract
Volatile organic compounds (VOCs) are the main source influencing the overall air quality of an environment. It is a well-known fact that coated furniture units, in the form of paints and varnishes, emit VOCs, reducing the air quality and resulting in significant health problems. Exposure time to such compounds is also an important parameter regarding their possible health effects. Such issues also have a greater influence when the exposure period is extended. The main objective of this study was to review some of the important factors for the emission of VOCs from coated furniture, from the perspective of material characteristics, as well as health concerns. Some methods for controlling VOC emissions to improve indoor air quality, from the point of view recent regulations and suggestions, are also presented in this work.

Quantification of microbiota-related phenols and aromatic acids in mouse feces of a diabetic nephropathy model by simultaneous BDAPE derivatization using ultra-performance liquid chromatography-tandem mass spectrometry. Anal Bioanal Chem 2020; 412:3241-3252.

Abstract
In the intestine, several phenols and aromatic acids are generated by microbiota and are highly related to the formation of uremic toxins. Herein, we developed a new derivatization reagent, 2-bromo-1-[4-(dimethylamino)phenyl] ethyl ketone (BDAPE), that reacted simultaneously with phenols and aromatic acids. Following a reaction within 2 h at 60 °C in the presence of 200 mM potassium carbonate (K2CO3), the obtained BDAPE derivatives were separated on a reversed-phase C18 column and quantified by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) in positive electrospray ionization mode. This method allowed a lower limit of quantification (LLOQ) of 0.090 μΜ for 3-indolepropionic acid (3IPA), indole-3-acetic acid (3IAA), p-cresol (PC), benzoic acid (BA), and phenol (PN); 0.30 μΜ for phenylacetic acid (PAA); 0.45 μΜ for 4-hydroxyphenylacetic acid (4HPAA); and 0.60 μΜ for 3-phenylpropionic acid (PPA). Methodological validation further demonstrated acceptable accuracy (%RE < 16.1) and precision (%RSD < 16.2), suggesting that this is a sensitive and robust method for simultaneous quantification of phenols and aromatic acids. The method was successfully applied to analyze these microbiota-related analytes in mouse feces of a diabetic nephropathy model. Graphical abstract.
