“…The sludge samples analyzed with DGGE are specified in Figure 5, and correspond to the most representative of each stage of experimentation. These are: for Stage I Lanes (2,3,4,5); Stage II (6,7,8); and Stage III (9,10). In the DGGE image in Figure 5, the results of the molecular tests for each sample, represented by vertical rails or bands, can be observed.…”

“…One group of such emerging pollutants are parabens, which include Methylparaben (MePB), Ethylparaben (EtPB), Propylparaben (PrPB) and Butylparaben (BrPB) [4], which are widely used alone or combined in everyday products such as cosmetics or personal care products. They are used to retard the growth of fungi and bacteria through their fungicidal and antimicrobial properties [5]. Parabens have received increasing attention due to their possible long-term effects on human health and aquatic organisms [6].…”

We evaluated the variation in microbial populations and the behavior of an SBR system in the removal of methylparaben (MePB). The experimentation was carried out for 14 weeks, in three operational stages as follows: stabilization (Stage I), (Stage II = 300 μgMePB/L and Stage III = 600 μgMePB/L). The variation of the microorganisms was analyzed over the experimentation time along with the contact with the pollutant to be degraded, and the removal percentage of COD and MePB, with results of 88±5,5% and 92±7,7% respectively. Kinetic of MePB removal was evaluated to obtain the rate constant of biological degradation, Kbiol. Using these kinetic results, the effect of different concentrations of MePB and biomass on biodegradation behavior was evaluated. Kbiol (LgSS-1d-1) values were obtained of 42.8 and 79 respectively; and 472±38.0 µgMePB/L, at biomass contents of 1466.7 and 2666.7 mgSSV/L, where Kbiol (LgSS-1d-1) values were obtained of 11.0 and 32.6 respectively.The variation of the microbial populations were analyzed using DGGE. The results obtained indicated that the populations presented similar characteristics between the stages. However, for the biomass samples of Stage I and stage III, significant differences were identified in the composition of microbial populations. Nonetheless, this did not affect the removal of MePB and the diversity conditions that characterize an aerobic system.

“…The ultrasonic bath is the most available and cheap ultrasonic device and allows batch sample treatment. It was often used to extract a wide variety of restricted and banned substances in cosmetics covering all categories of products: makeup powder, eye shadow, lipstick, sunscreen, bleaching cream, lotion, shampoo, soap, and hair dyes [67,71,[120][121][122][123][124][125][126][127][128][129][130][131].…”

The widespread applications of cosmetics in modern life make their analysis particularly important from a safety point of view. There is a wide variety of restricted ingredients and prohibited substances that primarily influence the safety of cosmetics. Sample preparation for cosmetic analysis is a crucial step as the complex matrices may seriously interfere with the determination of target analytes. In this review, some new developments (2010-2016) in sample preparation techniques for cosmetic analysis, including liquid-phase microextraction, solid-phase microextraction, matrix solid-phase dispersion, pressurized liquid extraction, cloud point extraction, ultrasound-assisted extraction, and microwave digestion, are presented. Furthermore, the research and progress in sample preparation techniques and their applications in the separation and purification of allowed ingredients and prohibited substances are reviewed.
