Abstract During the years 2014-2015, biomonitoring studies were carried out at three holding reservoirs located in Swietokrzyskie Province (central Poland): Kielce artificial lake, Chancza reservoir and Sielpia reservoir. In sea water algae Palmaria palmata (Linnaeus) Weber & Mohr, exposed in the analysed waters, the increases of concentrations were determined by the atomic absorption spectrometry method (AAS), of the following: Mn, Fe, Cu, Zn, Cd and Pb. Conductivity and pH were also determined in the reservoirs waters. The differences between the increases of heavy metal concentrations in the samples of algae found along the coastline were indicated; they result from different distances from the pollution sources, such as resorts, communication routes and industrial plants.

Abstract Biomonitoring studies have been carried out in three retention reservoirs located in the Opole Province (southern Poland): Turawa reservoir, Nysa reservoir and Otmuchow reservoir. The increases of concentrations of Mn, Fe, Cu, Zn, Cd and Pb in fresh water algae Spirogyra sp. and sea water Palmaria palmata (Linnaeus) Weber & Mohr, exposed in the analysed waters, were determined by the atomic absorption spectrometry method (AAS). Also the waters pH, conductivity and Mn and Fe concentrations were determined. The concentrations of Cu, Zn, Cd and Pb in the analysed waters were lower than the method limit of determination. The analyses were carried out during the period from June to July 2014. The differences between the increases of heavy metal concentrations in the samples of algae found along the coastline were indicated; they result from different distances from the pollution sources, such as sediments or drainage from the areas adjacent to the reservoirs. Better sorption characteristics of Palmaria palmata in comparison to Spirogyra sp. were indicated. An empirical interrelation was also tested, the application of which after modification may enable the quantitative assessment of waters pollution with heavy metals, based on the analysis of the concentration of the element in the algae thallus.

Abstract The aim of the carried out research was the assessment of the possibility to use a popular bioindicator - Pleurozium schreberi mosses as a biosensor of the air pollution in living quarters with the analytes originating from tobacco smoke. The moss bag method of active biomonitoring, popular in environmental studies, was applied; the method is based on exposing mosses collected in clean areas in the locations polluted with, for example, heavy metals. However, this experiment involved exposing mosses in living quarters, in which approximately 10 cigarettes were smoked daily (first room - kitchen). For the purpose of comparison, moss samples were also placed in another room (bedroom), which was potentially not polluted. After three months of exposure, the following heavy metals were determined in mosses: Mn, Fe, Ni, Cu, Zn, Cd, Pb and Hg, using the atomic absorption spectrometry method. Additionally, these analytes were also determined in hair samples from the persons smoking in the room and from other smokers; the determined metal concentrations were compared with the results of the studies carried out using hair samples collected from non-smokers. On the basis of carried out research it was confirmed that, among others, the mosses exposed in living quarters accumulate heavy metals, such as Ni, Zn, Pb and Hg, which originate from tobacco smoke. Higher heavy metal concentrations were determined in hair samples from smokers, compared to hair samples from non-smokers.

AbstractIn the year 2016, passive biomonitoring studies were conducted in the forest areas of southern and north-eastern Poland: the Karkonosze Mountains (Kark), the Beskidy Mountains (Beskid), Borecka Forest (P. Bor), Knyszynska Forest (P. Kny), and Białowieza Forest (P. Bia). This study used bark from the tree, Betula pendula Roth. Samples were collected in spring (Sp), summer (Su), and autumn (Au). Concentrations of Mn, Fe, Ni, Cu, Zn, Cd, and Pb were determined for the samples using the atomic absorption spectrometry method with flame excitation (F-AAS). Based on the obtained results, the studied areas were ranked according to level of heavy-metal deposition: forests of southern Poland > forests of north-eastern Poland. Some seasonal changes in the concentrations of metals accumulated in bark were also indicated, which is directly related to their changing concentrations in the air during the calendar year, for instance, the winter heating season produces higher concentrations of heavy metals in the bark samples taken in spring. When deciding to do biomonitoring studies using bark, but also other biological materials, it is necessary to take into account the period in which the conducted research is done and the time when the samples are taken for analysis, because this will have a significant impact on the obtained results.

Abstract Procedure for determination of chromium in biological materials by Zeeman graphite furnace atomic absorption spectrometry method using a Perkin-Elmer spectrometer equipped with hollow-cathode lamp at 357.9 nm was developed. The samples of animal tissues, food, and feed were digested in muffle furnace at 450ºC. The ash was dissolved in 1 N hydrochloric acid and the final solution was diluted in 0.2% nitric acid. Magnesium nitrate (1%) was used as a matrix modifier. The method was validated in terms of basic analytical parameters. The mean recoveries of chromium was 84.4% for muscle, 79.0% for canned meat, and 80.2% for feed, and analytical detection limit was 0.003 μg/g. Certified reference materials were used for analytical quality assurance. The proposed analytical procedure is well adapted for monitoring chromium content in food and feedstuffs. Content of total chromium in the tested samples (animal muscles and liver) was low and was situated in the range of 0.031-0.101 mg/kg (muscles) and 0.047-0.052 mg/kg (liver).
