“…Mixtures of toxic elements, such as Hg, Pb, Cd, or metal-associated toxicants such as methylmercury, tributyltin, alkyllead, and others, may occur in polluted aquatic systems and may be expected to cause combined toxicity (Bryan and Langston, 1992;Kadokami et al, 2013;McCready et al, 2006;Norwood et al, 2003;Rainbow, 1995). In some marine top-predatory fish, such as Atlantic and Mediterranean swordfish (Xiphias gladius), high concentrations of Hg, Pb and Cd are found and it is a concern that this chronic contamination through combined toxicity effects may have affected reproduction performance and contributed to an observed population decrease (Damiano et al, 2011).…”

Environmental regulatory edicts within the EU, such as the regulatory framework for chemicals REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals), the Water Framework Directive (WFD), and the Marine Strategy Framework Directive (MSFD) focus mainly on toxicity assessment of individual chemicals although the effect of contaminant mixtures is a matter of increasing concern. This discussion paper provides an overview of the field of combined effects in aquatic ecotoxicology and addresses some of the major challenges related to assessment of combined effects in connection with environmental risk assessment (ERA) and regulation. Potentials and obstacles related to different experimental, modelling and predictive ERA approaches are described. On-going ERA guideline and manual developments in Europe aiming to incorporate combined effects of contaminants, the use of different experimental approaches for providing combined effect data, the involvement of biomarkers to characterize Mode of Action and toxicity pathways and efforts to identify relevant risk scenarios related to combined effects are discussed.

“…These detected pollutants and their concentrations were almost identical to those obtained from same samples using a cartridge-type SPE method and liquid-liquid extraction method. 10 The log Kow values of the detected pollutants ranged from -0.07 (caffeine) to 14.6 (squalane), and their boiling points ranged from 176 C (1,3-dichloro-2-propanol) to 404 C (pyrene).…”

“…5 Its effectiveness has been demonstrated by several studies. [7][8][9][10] An efficient extraction method for a wide range of GC-MS-amenable SVOCs is required to take full advantage of the potential of the AIQS-DB system. For water samples, we developed a solid-phase extraction (SPE) method for AIQS-DB by using styrene-divinylbenzene (SDB) polymer and activated carbon cartridges previously.…”

To investigate the wide range of pollutants occurring in sewage sludge, an analytical method for comprehensive non-target screening is needed. To the best of our knowledge, no procedures currently exist for the full screening of organic contaminants in sewage sludge, which is the ultimate goal of this project. We developed non-discriminating sample preparation methods for gas chromatography-mass spectrometry (GC-MS) analysis. Pressurized liquid extraction (PLE) was used for extraction, with in-line (silica gel selective PLE, SPLE) or off-line clean-up (gel permeation chromatography, GPC). This combination allowed the analysis of non-polar compounds of all sizes and small semi-polar and non-polar compounds. The results show that the combination of SPLE and PLE with GPC is suitable for analysis of established as well as new contaminants. Both methods were validated for 99 compounds with different properties. For all GC suitable analytes, either one of the methods produced acceptable recoveries (64 to 136%). As a test, the two methods were used for non-target screening of Swedish sewage sludge. A tiered approach was used to tentatively identify the sludge contaminants. In total, 1865 and 1593 compounds were found of which 321 and 192 compounds were tentatively identified for the PLE and SPLE method, respectively. For a comprehensive coverage of contaminants, the two methods should be used together, with the PLE method covering a wider polarity range and the SPLE method a wider size range. In addition, polar substances will require liquid chromatography-mass spectrometry analysis, the method for which will be developed soon.Electronic supplementary materialThe online version of this article (doi:10.1007/s00216-017-0429-0) contains supplementary material, which is available to authorized users.
