“…Electric conductivity of lichen was pointed out as the most sensitive parameter of its physiological response to environmental stress, when compared to the normalized difference vegetation index and chlorophyll degradation.

The aim of this study is to understand emission sources of chemical elements using biomonitoring as a tool. The selected lichen and bark were respectively Parmotrema bangii and Criptomeria japonica, sampled in the pollution-free atmosphere of Azores (Sao Miguel island), Portugal, which were exposed in the courtyards of 22 basic schools of Lisbon. The exposure was from January to May 2008 and from June to October 2008 (designated through the text as winter and summer respectively). The chemical element concentrations were determined by INAA. Conductivity of the lichen samples was measured. Factor analysis (MCTTFA) was applied to winter/summer bark/lichen exposed datasets. As emission sources, soil with anthropogenic contamination, a Se source, traffic, industry, and a sea contribution, were identified. In lichens, a physiological source based on the conductivity values was found. The spatial study showed contribution of sources to specific school positioning. Conductivity values were high in summer in locations as international Lisbon airport and downtown. Lisbon is spatially influenced by marine air mass transportation. It is concluded that one air sampler in Lisbon might be enough to define the emission sources under which they are influenced.

“…Blanks of ultrapure polyethylene containers were dealt with in the same way as the samples. Additional details on irradiation conditions and reactor parameters for the current implementation of k 0 -INAA at the RPI-ITN may be found elsewhere [9,10]. Quality-assurance aspects for the k 0 -methodology have already been discussed as well [8,11].…”

In this work, superficial waters of two small rivers flowing in the São Domingos' abandoned mining area were analyzed in order to infer on soil-water transfer of the elements determined. Instrumental neutron activation analysis was used for elemental concentration assessment. The following elements were found at the mg L−1 level: As, Ba, Co, Cu, Fe, K, Na and Zn. The dry-mass residues varied between 70 mg and 1 g in 20-mL volumes. High enrichment relative to soil was found for most elements. Good statistical associations between Br and Na, between Cr and Sc, and between Ce, Co, Fe, Yb, and Zn, were found, suggesting a similar mechanism of soil-water, elemental transfer. Both the superficial waters' composition and their elemental levels indicate a potential risk of contamination of the underground waters and an actual health risk for the resident populations.

Inductively coupled plasma mass spectrometry (ICP-MS) and instrumental neutron activation analysis (INAA) were applied to study the elemental content of coal combustion residues. Both methods’ analytical applicability and suitability for this type of material were described in detail. A certified reference material, fine fly ash (CTA-FFA-1), was used to examine the capabilities and validation of both methods. A comparison study allowed for the modification of the procedures for these materials (previously elaborated in the Institute of Nuclear Chemistry and Technology), resulting in more accurate data with lower uncertainty. We highlighted that INAA and ICPs complemented each other in the analysis of coal and coal combustion residues. The digestion procedure was an integral part of the measurement and affected the environmental analysis results. Both methods were applied to the chemical characteristics of coal ashes from household furnaces. The hard coal was from Polish, Columbian, and Kazakh mines. The majority of elements had similar concentrations, independently of coal origin. Because ash from domestic coal combustion is used as a fertilizer or an anti-icing agent, we assessed the potential environmental impact via leaching experiments (according to PN-EN 12457-2). The potential risk of soil contamination due to ash dumping around the house and its surroundings was determined as insignificant (for the elements investigated).
