Bioindication capacity of metal pollution of native and transplanted Pleurozium schreberi under various levels of pollution

During a period of 90d assays were carried out with the moss Pleurozium schreberi transplanted from an uncontaminated control site to 27 sites selected in one of the most polluted regions of Upper Silesia (Poland). The native mosses of this species were collected from the polluted sites. Concentrations of Cd, Cr, Cu, Pb and Zn were determined in P. schreberi and in the soil of all of the sites. The sites were divided into more and less polluted ones. The obtained results indicate that the native P. schreberi from the more polluted sites accumulated significantly more Cd, Cr, Cu, Pb and Zn than the transplanted moss from the same sites. The transplanted P. schreberi from the less polluted sites accumulated significantly more Cr, Pb, Zn, significantly less Cu and comparable amounts of Cd, as compared to the native moss. The selection of native versus transplant P. schreberi as a bioindicator depends on the level of pollution.

δ34s values and s concentrations in native and transplanted pleurozium schreberi in a heavily industrialised area

Sulphur is an element found in surplus in anthropogenic areas and one of the minerals responsible for the development of acid rains. The analysis of stable S isotopes provides a powerful tool for studying various aspects of the biogeochemical circulation of sulphur. δ(34)S values and S concentrations were determined in a 90-day experiment with the native moss Pleurozium schreberi from rural, urban and industrial sites in Upper Silesia in southern Poland. At the same time P. schreberi from a control site was transplanted to the same rural, urban and industrial sites and the δ(34)S values and S concentrations were determined in the same 90-day experiment. (34)S enrichment (up to 4.7‰) in the mosses tested indicates that these plants responded to environmental pollution stress. Sulphur isotopic composition in the transplanted P. schreberi was related to S concentrations in this species after 90 days of the experiment. Higher δ(34)S values and S concentrations were noted in native mosses than in those transplanted from rural and urban sites while an opposite situation was reported in industrial sites. The transplanted P. schreberi was a better sulphur bioindicator than the native moss in more polluted industrial sites and worse in less polluted rural and urban sites.

Trace elements in the Fontinalis antipyretica from rivers receiving sewage of lignite and glass sand mining industry

Intensive lignite and glass sand mining and industrial processing release waste which may contain elements hazardous to the aquatic ecosystem and constitute a potential risk to human health. Therefore, their levels must be carefully controlled. As a result, we examined the effects of sewage on the aquatic Fontinalis antipyretica moss in the Nysa Łużycka (lignite industry) and the Kwisa Rivers (glass sand industry). The Nysa Łużycka and the Kwisa Rivers appeared to be heavily polluted with As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, V and Zn, which were reflected in the extremely high concentration of these elements in F. antipyretica along the studied watercourses. In the Nysa Łużycka, trace element composition in the moss species is affected by lignite industry with accumulation in its tissues of the highest concentrations of Cd, Co, Cr, Cu, Mn, Ni, Pb and Zn, while samples from the Kwisa sites influenced by glass sand industry revealed the highest concentrations of As, V and Fe. The principal component and classification analysis classifies the concentration of elements in the aquatic F. antipyretica moss, thus enabling the differentiation of sources of water pollution in areas affected by mining industry.

Metal contents in Centaurium erythraea and its biometry at various levels of environmental pollution

In this investigation we focus on the influence of pollution on concentration of elements in the medicinal Centaurium erythraea. This herb is collected from wild populations and also provides important information as monitor of environmental quality. Concentrations of Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, N, Ni, P, Pb, V and Zn in Centaurium erythraea and in the soil in which this plant grew were measured together with biometrical features of the species from sites affected by various levels of pollution. C. erythraea from sites polluted by lignite mining and industrial combustion had the highest concentrations of Cd, Co and Zn (principal component and classification analysis, PCCA). C. erythraea from sites influenced by ferrous-chromium and thermal power plants had the highest concentrations of Cr and Fe as well as Cu, Mn and Ni and the highest length of shoots and number of leaves, shoots, nodes, flowers and flowers on the main shoot. These luxurious growth forms were probably related to the highest concentrations of N, P and Fe in the soil and concentrations of N and K accumulated by C. erythraea on these sites as revealed by the established models. Controlling the collection of C. erythraea for medicinal purposes is recommended as this species is able to accumulate increased levels of metals from polluted sites. The medical quality of C. erythraea may be negatively related to the degree and type of pollution of the environment and should not be based on the luxurious growth of individuals which may contain hazardous levels of metals.

Transplanted Moss Hylocomium splendens as a Bioaccumulator of Trace Elements from Different Categories of Sampling Sites in the Upper Silesia Area (SW Poland): Bulk and Dry Deposition Impact

Concentrations of Cd, Co, Cr, Cu, Ni, K, Fe, Mn, Pb, V and Zn in transplants of Hylocomium splendens (Hedw.) Schimp. were compared with bulk deposition and dust samples from three different categories of sites: industrial, residential and their surroundings and rural (15 in total). Mosses were transplanted for 90 days to severely polluted areas of Upper Silesia, and samples of precipitation and dust were collected during the same period. Most of the significant correlations between element concentrations in mosses and bulk deposition (Cd, Ni, Pb and Zn) were found for industrial sites. In this study dry deposition carried higher element concentrations than bulk deposition, which may result in the higher passive capture of particulate matter by mosses.

Bioindication of PBDEs and PCBs by native and transplanted moss Pleurozium schreberi

PBDEs and PCBs are toxic, persistent organic pollutants (POPs), and the use of PCBs is forbidden, but they are still present in many environments and biota. 90-day assays were conducted with the moss Pleurozium schreberi transplanted from an uncontaminated control site to ten sites (rural and urban) selected in one of the most polluted regions of Upper Silesia in Poland. Native P. schreberi mosses were collected from the same ten polluted sites. Concentrations of PBDEs (28, 47, 66, 85, 99, 100, 153, 154, 183 and 209) and PCBs (28, 52, 101, 118, 138, 153, 180) were determined in all native and transplanted P. schreberi from all sites. Native P. schreberi contained the highest ΣPBDE and ΣPCB levels (63.6ngg-1 and 4.47pgg-1, respectively) when collected in the vicinity of a steel smelter. After 90 days of the experiment native and transplanted P. schreberi contained the highest concentrations of the same BDE 209 congener (88-91% of total PBDEs in the native mosses and 85-90% of the total PBDE burden in the transplants). The native and transplanted mosses from the industrial sites after 90 days of exposure contained significantly higher concentrations of all the examined PBDE and PCB congeners (except for 153 and 180) than mosses from rural sites. PBDE and PCB values were higher in native than in transplanted mosses after 90 days of exposure in both rural and industrial sites.

The Use of Moss Pleurozium schreberi (Brid.) Mitt. as Bioindicator of Radionuclide Contamination in Industrial Areas of Upper Silesia

Abstract Mosses are good bioaccumulators of radionuclides and from the 60 of the last century, they are used as bioindicators of radioactive contamination in the environment. Concentration of impurities in moss represent the accumulation in mosses during the past 2-3 years. As a result, the moss composition analysis provides information on an average contamination within a few vegetation seasons. During our survey the measurements of radionuclide activity concentrations in P. schreberi transplanted from places relatively clean to heavily contaminated areas of Upper Silesia were carried out. An increase in the radionuclides activity concentrations in P. schreberi transplants may indicate not only deposition of the radionuclides itself, but also an influx of other pollutants. The results showed no relationship between the Pb-210 activity concentration and activity concentrations of Pb-214, Bi-214, also belonging to the uranium-radium decay series. The increased concentration of Pb-210 in P. schreberi may be the result of the radionuclide atmospheric deposition, which appears in the environment as a result of fossil fuels burning. Excess, allogeneic Pb-210 can be used as marker of environmental pollution. In the areas with its higher activity concentration increased pollution can be expected delivered, for example, by local industry. The Project received financial assistance from the funds of the National Science Centre, granted by force of the decision no. UMO-2013/09/B/NZ8/03340 (NCN).

Polybrominated diphenyl ethers (PBDEs) in herbaceous Centaurium erythraea affected by various sources of environmental pollution.

Polybrominated diphenyl ethers (PBDEs) are persistent xenobiotics with harmful effects on humans and wildlife. Their levels in the environment and accumulation in biota must be carefully controlled especially in species harvested from wild populations and commonly used as medicines. Our objective has been to determine PBDE concentrations (BDEs 28, 47, 66, 85, 99, 100, 153, 154, 183 and 209) in Centaurium erythraea collected at sites with various levels of environmental pollution. PBDE congener profiles in C. erythraea were dominated by BDE209, which accounted for 47–89% of the total PBDE burden in the plants. Principal Component and Classification Analysis, which classifies the concentration of PBDEs in C. erythraea, allowed us to distinguish the pattern of these compounds characteristic for the origin of pollution: BDEs 28, 47, 66, 85, 99, 100 for lignite and general chemical industry and the vicinity of an expressway and BDEs 183 and 209 for a thermal power plant and ferrochrome smelting industry. Careful selection of sites with C. erythraea for medicinal purposes is necessary as this herb can accumulate PBDEs while growing at polluted sites.
