“…Both chloroform and chlorobenzene were previously used as extractants in BPA isolation by liquid–liquid microextraction [ 11 , 32 , 33 , 34 ]. Chlorobenzene has, so far, only been used a few times in USAEME for the determination of benzotriazoles, triazine herbicides in environmental water [ 35 , 36 , 37 ]. For BPs, the effect obtained for these two solvents is very similar.…”

A new, simple and sensitive method for isolating nine compounds from the bisphenol group (analogues: A, B, C, E, F, G, Cl2, Z, AP) based on one-step liquid–liquid microextraction with in situ acylation followed by gas chromatography-mass spectrometry was developed and validated using influent and effluent wastewaters. The chemometric approach based on the Taguchi method was used to optimize the main conditions of simultaneous extraction and derivatization. The recoveries of the proposed procedure ranged from 85 to 122%, and the repeatability expressed by the coefficient of variation did not exceed 8%. The method’s limits of detection were in the range of 0.4–64 ng/L, and the method’s limits of quantification ranged from 1.3 to 194 ng/L. The developed method was used to determine the presence of the tested compounds in wastewater from a municipal wastewater treatment plant located in northeastern Poland. From this sample, eight analytes were detected. Concentrations of bisphenol A of 400 ng/L in influent and 100 ng/L in effluent were recorded, whereas other bisphenols reached 67 and 50 ng/L for influent and effluent, respectively. The removal efficiency of bisphenol analogues in the tested wastewater treatment plant ranged from 7 to approximately 88%.

“…Ammonia and acetophenone, for example, were only found by Vautz et al [108]; 2-propanol was identified by Ireland et al [110]; ethyl acetate was only detected by Moura et al [10], and terpenes have been addressed by Rodríguez-Maecker et al [82], with a large group of specific analytes, such as limonene, α-pinene, and β-pinene being identified in this work. Atrazine and simazine have been stressed in the work by Kalhor et al [111]. Generally speaking, it is possible to see identical results in independent studies with a similar goal, which gives consistency to the IMS technique.…”

Volatile organic compounds (VOCs) can be extremely toxic and hazardous to expose humans in both indoor and outdoor environments; thus, their detection, correct identification, and accurate quantification are relevant and demanding tasks that need to be addressed. Fortunately, several known analytical techniques allow the qualitative and quantitative assessment of these compounds. This review paper stresses on two independent spectroscopic techniques, infrared spectroscopy and ion mobility spectrometry, both suitable for the detection of very small concentration levels of VOCs in gaseous samples. Infrared spectroscopy is a well-known technique that has been largely applied per se or combined with additional methodologies, to study VOCs at both high and low concentration levels. On the other hand, ion mobility spectrometry gained relevance in this field, due to its capability to measure trace concentration levels, namely ppbv and even pptv. For this review paper, several scientific papers were analyzed, and the most relevant were addressed throughout the text. The working principles of both techniques are carefully addressed, and updated data is provided for highlighting the advantages and disadvantages of both techniques for the environmental VOCs assessment in air quality control.
