“…The limits of quantitation (LOQs) were 0.04-17 ng/g for PBDEs, and 10-370 ng/g for OPFRs. In most proposed methods, many matrix interferents were co-extracted and coeluted along with PBDEs and OPFRs due to the inherent complexity of dust, even after an additional pre-cleanup by florisil [23][24][25]. Such interferences could possibly lead to an increase in the background in the mass spectrum, decrease instrumental selectivity and sensitivity, and in addition contaminate the GC system.…”

Flame retardants are associated to numerous adverse health effects, can accumulate in humans and have been used intensively worldwide. Recently, dust has been identified as a major human exposure route for flame retardants. The aim of this study was to develop a multi-residue method using a two-step SPE purification. It enabled us to effectively limit coextracted matrix/interferets and therefore a simultaneous analysis of brominated and organophosphate flame retardants for indoor dust was achieved. The optimized method was validated according to standard protocol and achieved good accuracy and reproducibility (percent error ranged from -29 % to 28 %). Standard Reference Material (SRM) for dust was also analysed, and good agreement was found with reported brominated and organophosphate flame retardants (OPFRs) concentrations. The applicability of the validated method was demonstrated by the analysis of ten indoor dust samples from ten Australian homes. Overall 89 % of the analytes were detected in these samples. The average concentrations of ∑OPFRs and ∑PBDEs in those samples were 41 and 3.6 μg/g, respectively. Tris(2-butoxyethyl) phosphate and tris(2-chloroisopropyl) phosphate were the most abundant OPFRs, accounting for 57-92 % ∑OPFRs, while decabromodiphenyl ether dominated the Polybrominated diphenyl ethers (PBDE) congeners contributing between 71-94 % to the ∑PBDEs.

“…Society uses a vast array of compounds for a range of uses including personal care, food preparation and preservation, medication (human and animal), industrial manufacturing processes and agriculture. A growing number of microorganic contaminants have been found in groundwater resources over the last few decades as analytical techniques have become more affordable and advanced and as awareness of different sources of contaminants has grown (Farré et al, 2012;Lapworth et al, 2012). Many of these are now being detected in urban groundwater across the world (Duong et al, 2015;Jurado et al, 2014;Jurado et al, 2012;Lin et al, 2015;López-Serna et al, 2013;Osenbrück et al, 2007) The sources and pathways for organic micro-pollutants to reach the groundwater include point and diffuse sources and are summarised for an urban settings in Stuart et al (2012).…”

It has long been known that groundwaters beneath urban areas carry a fingerprint from urban activities but finding a consistent tracer for anthropogenic influence has proved elusive. The varied sources of urban contaminants means that a single consistent and inexpensive means of tracing the fate of urban contaminants is not generally possible and multiple tracers are often required to understand the contaminant sources and pathways in these complex systems. This study has utilized a combination of micro-organic (MO) contaminants and inorganic hydrochemistry to trace recharge pathways and quantify the variability of groundwater quality in multi-level piezometers in the city of Doncaster, UK. A total of 23 MO's were detected during this study, with more compounds consistently detected during higher groundwater table conditions highlighting the importance of sampling under different hydrological conditions. Four of the compounds detected are EU Water Framework Directive priority substances; atrazine, simazine, naphthalene and DEHP, with a maximum concentration of 0.18, 0.03, 0.2, 16 µg/l respectively. Our study shows that the burden of the banned pesticide atrazine persisting in the Sherwood sandstone is detected at two of the three study sites. Emerging contaminants' are seen throughout the borehole profiles and provide insights into transient pathways for contaminant migration in the sub-surface. Long term changes in inorganic hydrochemistry show possible changes in contaminant input or the dissolution of minerals. Nitrate was detected above 50 mg/L but on the whole nitrate concentrations have declined in the intervening years either due to a reduction of nitrate application at the surface or a migration of peak nitrate concentrations laterally or to greater depth. This study shows that multiple tracers together with multi-level piezometers can give a better resolution of contaminant pathways and variable flow regimes within the relatively uncomplicated aquifer of the Sherwood Sandstone compared with single long screened wells.

“…Organic compounds previously not known to be significant in freshwater, in terms of distribution and/or concentration, are now being more widely detected as analytical techniques improve [1]. These compounds, which have the potential to cause known or suspected adverse ecological or human health effects, are often collectively referred to as emerging contaminants (ECs) [2].…”

Concern for the natural environment increasingly devotes more attention to growing potential hazards resulting from the release of various substances. Currently, one of the main problems associated with environmental pollution is the derivation of organic compounds from wastewater. Substances derived from sewage leaks into the environment in the form of a multicomponent mixtures often enhances the toxic effects caused by these compounds. While analyzing the reports in the literature of the last two decades it can be seen that substantial efforts are devoted to the determination of selected trace contaminants present in wastewater. Among the most marked there are endocrine disrupting compounds, residues of pharmaceuticals and personal care products, plastics and sunscreens. Recently, a new group of compounds joined the aforementioned contaminants, namely drugs, whose legality and availability is increasing every year. Exposure to these type of compounds, named in the literature as emerging contaminants (ECs), involves, among others, such effects as hormonal imbalance, reduction of the survivability of aquatic organisms and reproductive problems.This paper provides a review of the types of emerging organic groundwater contaminants (EGCs) which are beginning to be found in the natural environment in many countries all around the world.
