Biomonitoring of Atmospheric Aerosol with the use of Apis mellifera and Pleurozium schreberi

2019

The aim of the carried out research was to assess atmospheric aerosol pollution levels in the area of three apiaries located in the Opole Province and to analyse heavy metals pollution in bee honey and western honey bees. Pleurozium schreberi moss was used in analysing atmospheric aerosol pollution with the active biomonitoring method, whereas heavy metals levels were determined with flame atomic absorption spectrometry method (F-AAS). Relative Accumulation Factors (RAF) were used in determining increases of analytes concentrations in the moss samples. As a result of the carried out study, the following conclusions have been reached: mosses are good bioindicators of environment pollution th…

Mosses as biomonitor of air pollution with analytes originating from tobacco smoke

2018

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 wa…

Is Your Moss Alive during Active Biomonitoring Study?

2021

Biomonitoring was proposed to assess the condition of living organisms or entire ecosystems with the use of bioindicators—species sensitive to specific pollutants. It is important that the bioindicator species remains alive for as long as possible while retaining the ability to react to the negative effects of pollution (elimination/neutralization of hazardous contaminants). The purpose of the study was to assess the survival of Pleurozium schreberi moss during exposure (moss-bag technique) based on the measurement of the concentration of elements (Ni, Cu, Zn, Cd, and Pb), chlorophyll content, and its fluorescence. The study was carried out using a CCM-300 portable chlorophyll content meter…

The influence of preparation methodology on the concentrations of heavy metals in Pleurozium schreberi moss samples prior to use in active biomonitor…

2020

AbstractActive biomonitoring is used to assess environmental pollution of elements such as heavy metals by indicator species such as mosses. They are used, among others, in urbanized areas where no indicator species are found. In such study areas, mosses collected from sites considered to be ecologically clean shall be exposed. In this context, it is very important to prepare the mosses properly before the exposure, so that the information received about the condition of the environment is reliable. In 2018, studies were conducted in the forested areas of southern Poland—in Opolskie Province. Pleurozium schreberi mosses were used in these studies. Atomic absorption spectrometry with flame a…

Trace elements in native and transplanted Fontinalis antipyretica and Platyhypnidium riparioides from rivers polluted by uranium mining.

2017

The past uranium/polymetallic mining activities in the Sudety (SW Poland) left abandoned mines, pits, and dumps of waste rocks with trace elements and radionuclides which may erode or leach out and create a potential risk for the aquatic ecosystem, among others. In the present work four rivers affected by effluents from such mines were selected to evaluate the application of aquatic mosses for the bioindication of 56 elements. Naturally growing F. antipyretica and P. riparioides were compared with transplanted samples of the same species. The results demonstrate serious pollution of the examined rivers, especially with As, Ba, Fe, Mn, Pb, Ti, U and Zn, reaching extremely high concentrations…

Sorption of Cadmium and Zinc in Selected Species of Epigeic Mosses

2014

The sorption abilities of seven moss species growing on the area of Bory Stobrawskie forest (southern Poland) were tested in laboratory. Sorption was carried out in solutions of Zn and Cd chlorides. It has been shown that the sorption properties depend on the moss species and increases in the series as follows: Polytrichum commune < Leucobryum glaucum < Eurhynchium praelongum < Thuidium tamtariscifolium ≤ Dicranum scoparium ≤ Pleurozium schreberi < Sphagnum sp. With help of microscope images, it was also demonstrated that one of the factors affecting the sorption properties of mosses was the level of their surface development. The determined sorption capacity of Zn varies according to speci…

On the mend of bryophyte conservation in Spain: preparing a proposal for the inclusion of bryophytes in national species protection catalogues

2018

The Spanish bryoflora contains 1291 taxa, 272 of them included in the Spanish Red List under any threat category. Although bryophytes show a low rate of endemicity compared to vascular flora, Spanish administration’s responsibility for the conservation of these plants is very high, since the country has 63 exclusive or rare species on a European or world scale. However, the representation of this group of plants in the Spanish legislation on species conservation is merely anecdotal. Royal Decree 139/2011 of 4 February develops a list of wild protected species (LESRPE and CEEA, Spanish abbreviations) and includes only 10 species of bryophytes, all of them from the Directive Habitats and the …

Lectotypification of the spikemosses Selaginella denticulata and S. ornithopodioides (Selaginellaceae, Lycopsida)

2015

The typification of the names Selaginella denticulata (L.) Spring (≡ Lycopodium denticulatum L.) and S . ornithopodioides (L.) Spring (≡ L . ornithopodioides L.) (Selaginellaceae) is discussed. A specimen at LINN is designated as the lectotype of S . denticulata , and a specimen at BM is designated as the second-step lectotype of the name S . ornithopodioides .

The use of mosses in biomonitoring of selected areas In Poland and Spitsbergen in the years From 1975 to 2014

2015

Przeanalizowano historyczne zmiany stężeń metali ciężkich: Mn, Ni, Cu, Zn, Cd i Pb zakumulowanych w próbkach mchów pobieranych do badań w Polsce, na terenach leśnych Beskidów i Karkonoszy oraz w lasach północno-wschodniej części kraju, w odniesieniu do mało zanieczyszczonych obszarów Archipelagu Svalbard, którego największą wyspą jest Spitsbergen. Wyniki badań przedstawianych w literaturze uzupełniono wynikami badań własnych, prowadzonych w 2014 r. Wykazano, że spośród wymienionych obszary Beskidów oraz Karkonoszy były i są najbardziej narażone na depozycję metali ciężkich. Stwierdzono również, że na przestrzeni lat 1975-2014 nastąpiło znaczące zmniejszenie stężeń Cu, Zn, Cd i Pb w mchach p…
