“…In our opinion, moss vitality measurements should not be excluded during experiments [31]. Despite the high proportion of analyses using devitalized mosses [67][68][69][70], we still believe that this approach is inadequate, according to the definition of biomonitoring and bioindicators, i.e., living indicator organisms [71][72][73][74]. Otherwise, we treat moss only as a chemical adsorbent, i.e., a natural sorbent [75][76][77] that has nothing to do with biomonitoring.…”

Recently, significant attention has been paid to air quality awareness and its impact on human health, especially in urban agglomerations. Many types of dust samplers for air quality monitoring are used by governmental environmental monitoring agencies. However, these techniques are associated with high costs; as a consequence, biological methods such as active moss biomonitoring are being developed. The main disadvantages of such techniques are the lack of standardization of the preparation procedures and the lack of reliable comparisons of results with data from instrumental analyses. Our study aimed to compare the results obtained from active biomonitoring with the use of three moss species: Pleurozium schreberi, Sphagnum fallax and Dicranum polysetum. Samples were exposed via the moss-bag technique to measure the concentrations of analytes (Mn, Fe, Cu, Zn, Cd, Hg and Pb) which had accumulated among the total suspended particulates (TSP) collected from the filters of a dust collector in the city of Opole (Opole voivodeship, Poland). With regard to the physicochemical and biological traits of the mosses, their assessed lifetime and actual photochemical efficiency (yield) following exposure were meagre, which may have been related to the change of environment and their exposure to pollutants. When comparing the results obtained by the two methods used to monitor air pollution, the biomonitoring method was found to be incompletely consistent with the reference method. Biological monitoring using mosses must be carefully considered depending on the monitoring objectives, the required level of sensitivity and quality of measurement and the type of pollutant.

“…Goodman and Roberts carried out the first study of air pollution with mosses using the moss‐bag active biomonitoring technique, which was slightly modified later by Little and has been used and revised to standardize any treatments associated with it (Ares et al, 2012). This method is competitive with instrumental measurements because of its low cost, simplicity, and uncomplicated sample preparation, possibility to control exposure time and potential for a highly resolved spatial resolution of biomonitoring networks (Morales‐Casa et al, 2019; Turgut et al, 2019). After 50 years of use, this method is in continuous optimization (De Nicola et al, 2013; Rogova et al, 2018), which prevents its use as a regular environmental monitoring tool by official organizations (Aničić Urošević & Milićević, 2020).…”

“…It involves covering with plastic pots to prevent moss bags from being exposed to wet deposition (Sun et al, 2009). It is used to distinguish and prioritize accumulation pathways of a given metal (Tan et al, 2000) and to determine the degree and type of contamination, mainly in industrial areas (De Agostini et al, 2020; Morales‐Casa et al, 2019). Nowadays, it is rarely applied, knowing that the pollutants accumulated by mosses are the sum of both dry and wet deposition (Schröder & Nickel, 2019; Xiao & Liu, 2011).…”

“…According to the definition of biomonitoring, it uses whole or parts of living organisms that serve as a biomonitor of environmental quality and not just as a chemical adsorbent (Boquete et al, 2017; Markert & Wünschmann, 2011). Meanwhile, many works use devitalized material (Debén et al, 2016; Di Palma et al, 2017; Morales‐Casa et al, 2019), justifying this by the excellent sorption properties of the samples (Ares, Aboal, et al, 2015), but as it turns out not for all types of pollutants (Varela et al, 2016). It has also been shown that there are differences between dried and kept alive (hydroponic) mosses in sorption of pollutants (Szczepaniak et al, 2007).…”

The most widespread and used technique is the moss-bag method in active biomonitoring of air pollution using mosses. In the literature, we can find various studies on the standardization of this method, including attempts to standardize treatments and preparation procedures for their universal application. Few works comprehensively focus on other methods or compare other techniques used in active biomonitoring with mosses, especially including measurements of their vital parameters. Our experiment aimed to assess air pollution by selected heavy metals (Cu, Zn, Cd, Pb, Mn, Fe, and Hg) using three moss species (Pleurozium schreberi, Sphagnum fallax, and Dicranum polysetum) during a 12-week exposure in an urban area. Mosses were exposed simultaneously using four techniques: moss bag in three variants (exposed to air for total deposition of heavy metals, exposed to air for only dry deposition, and sheltered from the wind) and transplants in boxes. Increases in heavy metal concentrations in mosses were determined using the relative accumulation factor (RAF). The actual quantum yield of photosystem II photochemical was also analyzed as the main vitality parameter. The results indicate that all moss species during the changing environmental conditions survived and retained their vitality, although it decreased by >50% during the exposure. The best biomonitor was the moss P. schreberi, whose RAF increments were the highest throughout the study period for the majority of elements. The moss-bag technique had a statistically significant effect (almost 40%) on the concentration value of a given metal for a certain species, and thus it is the most recommended technique that can be applied in air quality monitoring in urban areas.

The study aimed to evaluate the level of air contamination in the area around the Kosogorsky industrial enterprise in Tula, Russia, in the winter of 2021/2022. For the study, Pleurozium schreberi, Sphagnum fallax, and Dicranum polysetum mosses were used for the first time in the 3-month active biomonitoring (moss-bag technique). Heavy metals elements (Mn, Fe, Ni, Cu, Zn, Cd, and Pb) were determined using atomic absorption spectrometry. In addition, mercury concentrations were determined with an AMA254 apparatus. The study's results for Fe, Cu, Zn, Pb, and Hg confirm the statistical significance of the species' effect on the accumulation of these elements. Values of relative accumulation factor (RAF) > 1.00 at selected measurement points indicate that the site is contaminated as a result of industrial activities (mainly Mn and Fe). Wind direction influenced moss contamination at selected measurement points, which was confirmed by cluster analysis. In the future, long-term or different seasons biomonitoring studies should be conducted in this area.
