They are in fact more toxic than their parent PAHs. One valuable diagnosis of atmospheric pollution can be obtained using biomonitors such as mosses. These biomonitors can provide information about air pollution over long periods of time in wilderness areas. Thus, they can serve as monitors of the atmospheric transport of pollutants. In this study, atmospheric pressure gas chromatography coupled to a quadrupole hyphenated to a time of flight mass spectrometer (APGC–MS/Q-TOF) has been examined for the identification of target analytes (15 PAHs and 8 NPAHs) for subsequent use in the analysis of mosses. Working ranges in low g g-1 concentration levels were obtained with most correlation coefficients higher than 0.999. All LODs were in the 0.007–0.035 g g-1 range and higher LODs (0.035 g g-1) were obtained for the less volatile PAHs with higher mass and retention times: benzo(g,h,i)perylene, dibenz(a,h)anthracene and indeno(1,2,3-c,d)pyrene. These LODs are of importance for the intended use, biomonitoring, especially taking into account that NPAHs are commonly found at very low concentration levels. Recoveries from mosses ranged from 75 to 98%. Intraday and interday precision ranged from 1.8 to 11.1% RSD and from 2.4 to 16.7% RSD, respectively. Very low concentrations of NPAHs were found in mosses compared to those of PAHs. All these data were used for pattern recognition of the pollutant source. The results are shown and discussed. 000149752 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000149752 590__ $$a4.612$$b2012 000149752 591__ $$aCHEMISTRY, ANALYTICAL$$b6 / 74 = 0.081$$c2012$$dQ1$$eT1 000149752 591__ $$aBIOCHEMICAL RESEARCH METHODS$$b12 / 74 = 0.162$$c2012$$dQ1$$eT1 000149752 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000149752 700__ $$0(orcid)0000-0003-2638-9221$$aCanellas, E. 000149752 700__ $$0(orcid)0000-0002-3703-7902$$aAlfaro, P.$$uUniversidad de Zaragoza 000149752 700__ $$0(orcid)0000-0003-3387-0419$$aRodriguez-Lafuente, A.$$uUniversidad de Zaragoza 000149752 700__ $$0(orcid)0000-0003-2685-5739$$aNerin, C.$$uUniversidad de Zaragoza 000149752 7102_ $$12009$$2750$$aUniversidad de Zaragoza$$bDpto.
