Biomonitoring aktywny z zastosowaniem mchów w pobliżu Miasteczka Śląskiego

2017

Celem przeprowadzonych badań była ocena przyrostu stężeń wybranych analitów w próbkach mchów. Badania biomonitoringowe zanieczyszczenia aerozolu atmosferycznego prowadzono na terenie miejscowości Miasteczko Śląskie (województwo śląskie). Potencjalnym emitorem zanieczyszczeń na obszarze badań jest Huta Cynku „Miasteczko Śląskie”. Zastosowano metodę biomontoringu aktywnego (metoda woreczkowa), wykorzystując mchy z gatunku Pleurozium schreberi (rokietnik pospolity). Metale ciężkie w próbkach mchów oznaczono za pomocą absorpcyjnej spektrometrii atomowej (AAS). Wyniki badań zinterpretowano, wyznaczając współczynnik akumulacji względnej (RAF). Podczas prowadzenia eksperymentu uwzględniono odległo…

Mosses as a biomonitor to identify elements released into the air as a result of car workshop activities

2022

Human activity as a result of civilization development contributes to creating new sources of environmental pollution. Air pollution is one of the major problems because it affects the fauna and flora, and people themselves. There is a lack of public awareness of the level of atmospheric analytes pollution emitted from people's occupational and recreational (leisure) activities. A quick, cheap and easy way to investigate the state of the environment is to use organisms-biomonitors that indicate the level of environmental pollution. The study aimed to assess air pollution in an urban area using three moss species: Sphagnum fallax, Pleurozium schreberi and Dicranum polysetum. Mosses were expo…

Influence of Heavy Metal Concentration on Chlorophyll Content in Pleurozium schreberi Mosses

2020

Abstract The aim of biomonitoring is assessment of environment condition. Biomonitoring studies with the use of mosses focus mainly on analytes accumulation and determining elements’ concentrations in the study area. It is often forgotten that a bioindicator should be alive during biomonitoring studies (which can be determined by, e.g., analysis of chlorophyll content). The objective of the carried out research was an assessment of the influence of selected heavy metals concentration: Ni, Cu, Zn, Cd and Pb accumulated by Pleurozium schreberi mosses during 3-month exposition within active biomonitoring, on their vitality, assessed by an analysis of a and b chlorophyll concentrations. The stu…

Passive and Active Biomonitoring of Atmospheric Aerosol with the Use of Mosses

2021

Abstract The aim of the carried out research was passive and active biomonitoring of woodlands in the Opole province. Pleurozium schreberi mosses were used during the research, in which the following heavy metals concentrations were determined: Mn, Fe, Ni, Cu, Zn, Cd and Pb. Concentrations were determined with absorption atomic spectrometry (AAS). On the basis of the carried out research, concentrations of heavy metals in moss samples used in the passive and active biomonitoring methods were compared. The obtained results indicate that Pleurozium schreberi mosses can be successfully used in both passive and active biomonitoring, however, these methods should not be used interchangeably in a…

Effects of tobacco smoke on indoor air quality: the use of mosses in biomonitoring.

2020

This research was carried out to assess the possibility of using Pleurozium schreberi mosses as bioindicators of atmospheric aerosol pollution in living quarters (kitchen and bedroom), with metals originating from tobacco smoke from various types of cigarettes: conventional cigarettes, e-cigarettes and heated tobacco products. The moss-bag method of active biomonitoring was used. The mosses were exposed in these indoor spaces for three months and, after the exposition period, their analytes – Ni, Cu, Zn, Cd and Pb – were determined using flame atomic absorption spectrometry (F-AAS). Results were interpreted using the relative accumulation factors (RAF), coefficients of variation (CV) and th…

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 environmental conditions on the lifespan of mosses under long-term active biomonitoring

2021

Abstract Biomonitoring with living organisms is most often used in order to gather quick information about environmental quality – for example the level of heavy metals polluting the air. Experiments are not often performed when the bioindicator is exposed to pollutants over the long time (6 months and more) because this period required to obtain credible results and the risk not yet studied of physiological changes and of degeneration of the living material which would undoubtedly affect the biomonitoring results. The aim of study was to evaluate the physiological condition of Pleurozium schreberi moss species subjected to continuous exposure for a year, using the moss-bag method, under va…

Using mosses as biomonitors to study trace element emissions and their distribution in six different volcanic areas

2017

Volcanoes emit SO2, CO2, and H2S, but also trace elements gases and particles such as As, Cd, Cr, Cu, Hg, Ni, Pb, and Sb. Active moss bag biomonitoring, an easy to apply and low budget method, was used to determine trace element release from volcanic areas of different geological context and climates. Exposure height variations (0.7–1.6 m above ground) due to different availability of natural tie points did not affect the results. Accumulation was linear for exposure durations from three days to nine weeks, so values were comparable by normalization to moss exposure time. Uncovered moss bags showed higher accumulation than co-exposed covered ones because of additional dust and wet deposit…
