“…Particularly for the analysis of endocrine disrupting chemicals in water matrices by GC-MS, many sample preparation techniques have been applied, among which we can find conventional extraction methods, such as LLE [13] and SPE [14][15][16][17][18], as well as approaches like dispersive solid-phase extraction [15], dispersive liquid-liquid microextraction [19][20][21], microextraction by packed sorbent [22] and micelle-mediated extraction solvent back extraction [23]. Both LLE [24,25] and dispersive liquid-liquid microextraction [21], as well as SPE [26] and dispersive solid-phase extraction [15] have been combined with derivatization procedures, making them even more time-consuming and expensive, while also requiring the use of hazardous reagents.…”

A fast gas chromatography/mass spectrometry method was developed and validated for the analysis of the potential endocrine disrupters octinoxate and oxybenzone in swimming pool water samples based on the solvent-free solid-phase microextraction technique. The low-pressure gas chromatography/mass spectrometry method used for the fast identification of UV filter substances was compared to a conventional method in terms of sensitivity and speed. The fast method proposed resulted in 2 min runs, leading to an eightfold decrease in the total analysis time and a sevenfold improvement in detection limits. The main parameters affecting the solid-phase microextraction process were also studied in detail and the optimized conditions were as follows: fiber coating, polyacrylate; extraction mode, direct immersion; extraction temperature, 25°C; sample volume, 5 mL; extraction time 45 min; pH 6.5. Under the optimized conditions, a linear response was obtained in the concentration range of 0.5-25 μg/L with correlation coefficients in the range 0.990-0.999. The limits of detection were 0.17-0.29 μg/L, and the recoveries were 80-83%. Combined method uncertainty was assessed and found to be less than 7% for both analytes for concentrations equal to or higher than 5 μg/L. Pool water samples were analyzed to demonstrate the applicability of the proposed method. Neither octinoxate nor oxybenzone were detected in the swimming pool water samples at concentrations above the respective limits of detection.

“…Higher concentrations were found in Germany, for camphor 4-MBC (2.4 µg/L) (Moeder et al, 2010), salicylate ES (0.8 µg/L), cinnamate derivatives EMC (3.01 µg/L) and IMC (146 ng/L), crylene OC (4.4 µg/L) and dibenzoyl methane BMDM (2.4 µg/L) (Rodil et al, 2009). It is worth mention that BMDM was not detected in any river water.…”

“…Other less conventional methodologies were also applied to water samples in order to extract the organic compounds, like ionic liquid based ultrasound-assisted emulsification microextraction (IL-USAEME) (Ge and Lee, 2012) with around 100% recovery, ionic liquid-based single-drop microextraction (IL-SDME) (Vidal et al, 2010) with average recovery of 100%, non-porous membrane-assisted liquid-liquid extraction (MALLE) (Rodil et al, 2009b) yielding 60 to 100% recovery, magnetic nanoparticles dispersive solid-phase extraction (MNPs-based dSPE) (Román et al, 2011) with about 70-125% recovery, microextraction by packed sorbent (MEPS) (Moeder et al, 2010) with 60 to 115% and micelle mediated extraction (MME) (Giokas et al, 2005) with average recoveries of 100%. These techniques are relatively new and their applicability to extract UV-filters from water samples has been poorly investigated.…”

UV-filters are a group of compounds designed mainly to protect skin against UVA and UVB radiation, but they are also included in plastics, furniture, etc., to protect products from light damage. Their massive use in sunscreens for skin protection has been increasing due to the awareness of the chronic and acute effects of UV radiation. Some organic UV-filters have raised significant concerns in the past few years for their continuous usage, persistent input and potential threat to ecological environment and human health. UV-filters end up is wastewater and because wastewater treatment plants are not efficient in removing them, lipophilic compounds tend to sorb onto sludge and hydrophilics end up in river water, contaminating the existing biota. To better understand the risk associated with UV-filters in the environment a thorough review regarding their physicochemical properties, toxicity and environmental degradation, analytical methods and their occurrence was conducted.Higher UV-filter concentrations were found in rivers, reaching 0.3 mg/L for the most studied family, the benzophenone derivatives. Concentrations in the ng to µg/L range were also detected for the paminobenzoic acid, cinnamate, crylene and benzoyl methane derivatives in lake and sea water.Although at lower levels (few ng/L), UV-filters were also found in tap and groundwater. Swimming pool water is also a sink for UV-filters and its chlorine by-products, at the µg/L range, highlighting the benzophenone and benzimidazole derivatives. Soils and sediments are not frequently studied, but concentrations in the µg/L range have already been found especially for the benzophenone and crylene derivatives. Aquatic biota is frequently studied and UV-filters are found in the ng/g-dw range with higher values for fish and mussels. It has been concluded that more information regarding UVfilter degradation studies both in water and sediments is necessary and environmental occurrences should be monitored more frequently and deeply.

“…However, LD is mandatory [74] if LC is going to be used. Microextraction by packed sorbent (MEPS) was also used by Moeder et al [44], followed by LD in 50 μL of ethyl acetate, which were all injected into the GC system employing the large volume injection (LVI) approach using a programmed temperature vaporizer (PTV) injector. SBSE constitutes another solid phase-based microextraction technique commonly employed for UV filters determination in environmental water samples [25,30,31,41,45,55,56,65,66,68,80].…”

Personal-care products (PCPs) could reach the aquatic environment and cause a great impact in the aquatic ecosystem. In this sense, the monitoring of these emerging pollutants in the environment yields valuable information. For this reason, analytical methods to determine PCPs in environmental waters are needed. Due to the low concentration of the PCPs, i.e. ng L À1 , sensitive methods are needed. This required sensitivity can be achieved by using sensitive analytical techniques during the measurement step, or by employing enrichment techniques during the sample treatment step. Obviously, the combination of both sensitive analytical techniques and extraction techniques considerably improves the quality of the determination.In this way, in the last years, different analytical methods have been developed to determine PCPs in environmental waters from different origin, i.e., water from sea, lake, river, influent and/or effluent wastewater treatment plant, swimming pool, tap, and groundwater. The aim of this chapter is to compile and discuss the analytical literature dealing with the development and validation of analytical methods for determining PCPs in environmental water samples, emphasizing both the employed sample treatment and the subsequent analytical technique.
