“…The pharmaceutical concentrations in the analyzed WWTP effluents fell within the range of concentrations reported in a recent review (Pal et al 2010). In contrast, almost 40 % of the analyzed pharmaceuticals (e.g., naproxen and diclofenac) in river waters were found at concentrations higher than those reported for other European rivers (Pal et al 2010), but similar to those previously reported in the Ebro river (Gros et al 2007). In fact, the levels of some pharmaceuticals close to the discharge of WWTP effluents (sites d1 and d2)…”

“…A multitude of organic compounds used in households, such as pharmaceuticals, enter surface waters mainly via point-source discharges of wastewater treatment plants (WWTPs) (Gros et al 2007;Pal et al 2010). Although most of these pharmaceuticals are present at low concentrations, many of them raise environmental and health concerns, and have become a key environmental problem (Schwarzenbach et al 2006).…”

“…Reliability of these models is however constrained by the high variability in chemical emissions from WWTPs and attenuation in surface waters (Pistocchi et al 2010). On the one hand, chemical emissions from WWTP effluents vary widely because of differences in regional usage of the compounds and efficiency of wastewater treatment (Pal et al 2010). On the other hand, the processes that drive in-stream attenuation (i.e.…”

Amultitude of pharmaceuticals enter surface waters via discharges of wastewater treatment plants (WWTPs), and many raise environmental and health concerns. Chemical fate models predict their concentrations using estimates of mass loading, dilution and in-stream attenuation. However, current comprehension of the attenuation rates remains a limiting factor for predictive models.We assessed in-stream attenuation of 75 pharmaceuticals in 4 river segments, aiming to characterize in-stream attenuation variability among different pharmaceutical compounds, as well as among river segments differing in environmental conditions. Our study revealed that in-streamattenuation was highly variable among pharmaceuticals and river segments and that none of the considered pharmaceutical physicochemical and molecular properties proved to be relevant in determining the mean attenuation rates. Instead, the octanol–water partition coefficient (Kow) influenced the variability of rates among river segments, likely due to its effect on sorption to sediments and suspended particles, and therefore influencing the balance between the different attenuation mechanisms (biotransformation, photolysis, sorption, and volatilization). The magnitude of themeasured attenuation rates urges scientists to consider themas important as dilutionwhen aiming to predict concentrations in freshwater ecosystemsThis research was supported by aMarie Curie European Reintegration Grant (PERG07-GA-2010-259219) and by a Marie Curie Career Integration Grant (PCIG9-GA-2011-293535) within the 7th European Community Framework Programme, aswell as by the SpanishMinistry of Economy and Competitiveness through the projects SCARCE (Consolider-Ingenio 2010 CSD2009-00065) and ENDERUS (CTM-2009-13018), and the postdoctoral grants “Juan de la Cierva” (jci-2009-05604 and jci-2010- 06397), and by the European Union through the European Regional Development Fund (FEDER).

This paper provides a review of the types of emerging organic groundwater contaminants (EGCs) which are beginning to be found in the UK. EGCs are compounds being found in groundwater that were previously not detectable or known to be significant and can come from agricultural, urban and rural point sources. EGCs include nanomaterials, pesticides, pharmaceuticals, industrial compounds, personal care products, fragrances, water treatment by-products, flame retardants and surfactants, as well as caffeine and nicotine. Many are relatively small polar molecules which may not be effectively removed by drinking water treatment. Data from the UK Environment Agency's groundwater screening programme for organic pollutants found within the 30 most frequently detected compounds a number of EGCs such as pesticide metabolites, caffeine and DEET. Specific determinands frequently detected include pesticides metabolites, pharmaceuticals including carbamazepine and triclosan, nicotine, food additives and alkyl phosphates. This paper discusses the routes by which these compounds enter groundwater, their toxicity and potential risks to drinking water and the environment. It identifies challenges that need to be met to minimise risk to drinking water and ecosystems.

Liquid chromatography/mass spectrometry (LC‐MS) technique enables analysis of emergent polar compounds without the need for derivatization reaction, while the introduction of high‐resolution mass analyzers in hybrid configurations makes possible to elucidate chemical structure, also without reference standards. Over the past 10 years, besides target analysis, the coupling of LC to high‐resolution mass spectrometry (HRMS) has allowed screening of compounds expected to be in the environment, as well as nontarget screening of unknown compounds, such as transformation products (TPs) formed in the environment or during technical wastewater and sewage purification treatments. Nowadays, analytical chemists are trying to achieve real nontarget analysis of numerous unknowns in environmental samples for a comprehensive view of the true overall contamination present in samples, but it still remains a very challenging issue. The development of new software tools to extract relevant data, spectra libraries, and databases will be of great help to solve this issue, enhancing the success rate. This article represents the second edition of a previous manuscript by Careri,2000 which was updated to take into account the huge progress in MS instrumentation and related methodologies and also advances in environmental analytical chemistry. In this overview, among the environmental applications of LC‐MS, current and innovative approaches for the analysis of selected classes of emerging pollutants, such as novel brominated flame retardants, nanomaterials, hormones and other endocrine disruptors, and pharmaceutical and personal care products in environmental samples are discussed.
