“…In this way compounds or elements can be extracted from the sample matrix [56]. Ultrasonic methods also increase the rate of reaction in sequential extractions [78] and assist with the homogenous suspension and distribution of slurries [80]. The application of UAE in the extraction of weakly bound organic compounds from their respective matrices is also possible [78], provided that the temperature does not exceed the tolerances of the analyte [80].…”

The ability of plants to hyper-accumulate metals and metalloids from the surrounding environment may pose a significant health risk to both humans and animals since plants form a substantial component of diet. This attribute, however, has also been identified as a useful tool in bioremediation and biomonitoring studies; where assimilated metal(loid)s in plants often correlate to environmental exposure. Since the bioavailability and toxicity of these elements depends upon their chemical form, speciation studies are essential in determining mobility and metabolic pathways. This can be done in a number of ways where sampling, pre-treatment and storage are all important factors affecting speciation. Appropriate analytical techniques for speciation studies can either be direct methods such as XAS, or indirect methods which require species separation prior to analysis. Separation techniques can be in the form of sequential extractions or column separation and analyte detection often utilises instrumentation such as ESI-MS, ICP-MS and ICP-OES.

“…These low molecular weight compounds are more widely dispersed (Yang et al, 1991) and denote a potential source of long-range contamination, away from the emitting sources. The heaviest PAHs are generally removed from the air by direct (e.g., wet) deposition processes (Blasco et al, 2006), thus having a lower transportability.…”

The ability of pine needles to capture polycyclic aromatic hydrocarbons (PAHs) from the surrounding air is well known. In this work the current knowledge of this affinity will be enhanced, investigating the plausible links between the concentrations of PAHs found in pine needles collected in different sites in Portugal, and several socio-geographic variables with environmental relevance. Canonical correlation analysis (CCA) has proven to be a suitable and innovative technique to look for relationships within environmental datasets. In the current work, CCA will simultaneously include chemical information (concentration of PAHs found in pine needles) and socio-geographic information associated to the sampling areas. In order to be more robust in these conclusions, Pinus pinea and Pinus pinaster species were considered separately, allowing an accurate direct comparison between them. The information concerning the different seasons and land occupation was also taken into account. Our results demonstrate how CCA can be a useful tool in environmental impact assessment, and highlight the importance of pine needles as trustful biomonitors of the influence of socio-geographic parameters on the levels of PAHs in a given area.

For PM 2.5 and PM 10 collection different approaches were followed using different type of filters and sample collectors. Samples of PM 2.5 were collected on glass fiber filters during one month with a medium volume sampler. For PM 10 , glass and quartz fiber filters were used and samples were collected simultaneously for one week using a high volume sampler. In addition, bark samples were collected at the same sites.
