“…Nevertheless, a large part of studies focuses only on the accumulation of selected elements by mosses, where large concentrations of metals are determined in various species, however, authors do not inform about the parameters of life functions [29][30][31]. In the context of biomonitoring studies it should be remembered that mosses are not only chemical adsorbent but also living organisms [32].…”

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 studies were also carried out in laboratory conditions, where the content of the dyes was determined with the aid of a UV-Vis spectrophotometer, in mosses reacting with solutions of various concentrations of the analysed metals. The content of elements in mosses after exposition and in solutions prior and after sorption were determined with the use of atomic absorption spectrometry (AAS) in a flame atomiser. After the carried out studies it was determined that mosses, during 12-week long exposition, accumulated heavy metals, which did not clearly influence the changes in chlorophyll content. The carried out studies prove that heavy metals are not the only and determining factor, which influences chlorophyll content in mosses as well as the bioindicator’s vitality in the conditions of environmental stress.

“…There is abundant evidence that PAHs are toxic to several flowering plant species affecting their germination (Maila and Cloete, 2002), reducing their root growth, leaf number and size and inducing stress responses (Alkio et al ., 2005). Non‐vascular plants, such as mosses, are due to their simple anatomy even more sensitive to xenobiotics and therefore widely used as bioindicators of soil, air and water pollution (Cortis et al ., 2016; Pradhan et al ., 2017). In this study we used the moss P. patens , to determine the efficiency of A. sydowii in reducing PAH toxicity.…”

Polycyclic aromatic hydrocarbons (PAHs) are among the most persistent xenobiotic compounds, with high toxicity effects. Mycoremediation with halophilic Aspergillus sydowii was used for their removal from a hypersaline medium (1 M NaCl). A. sydowii metabolized PAHs as sole carbon sources, resulting in the removal of up to 90% for both PAHs [benzo [a] pyrene (BaP) and phenanthrene (Phe)] after 10 days. Elimination of Phe and BaP was almost exclusively due to biotransformation and not adsorption by dead mycelium and did not correlate with the activity of lignin modifying enzymes (LME). Transcriptomes of A. sydowii grown on PAHs, or on glucose as control, both at hypersaline conditions, revealed 170 upregulated and 76 downregulated genes. Upregulated genes were related to starvation, cell wall remodelling, degradation and metabolism of xenobiotics, DNA/RNA metabolism, energy generation, signalling and general stress responses. Changes of LME expression levels were not detected, while the chloroperoxidase gene, possibly related to detoxification processes in fungi, was strongly upregulated. We propose that two parallel metabolic pathways (mitochondrial and cytosolic) are involved in degradation and detoxification of PAHs in A. sydowii resulting in intracellular oxidation of PAHs. To the best of our knowledge, this is the most comprehensive transcriptomic analysis on fungal degradation of PAHs.

“…Anthropogenic activities such as running power plants and automobiles lead to heavy contamination of the environment (Zinicovscaia et al, 2021). Some heavy metals are essential for the normal metabolic functioning of organisms, but when underprovided or excessive, they induce physiological stress with detrimental consequences (Prandan et al, 2017). Once heavy metals are introduced into the environment, it becomes di cult to eliminate them and accumulates in the tissues of plants and other organisms via the food chains.…”

This study investigated the deposition of heavy metals pollution in the University of Lagos, Akoka campus using the moss (Mnium hornum Hedw.) as a bioindicator. Samples of M. hornum. were collected in 2019 from four different locations within the University of Lagos campus: Faculty of Engineering (FE), Lagoon Front (LF), Main Library (ML) and Akintunde Ojo Library (AKT). A control sampling was done at First Estate, Amuwo-Odofin LGA (CL). The concentrations of Cadmium (Cd), Cobalt (Co), Chromium (Cr), Copper (Cu), Iron (Fe), Manganese (Mn), Nickel (Ni), Lead (Pb), and Zinc (Zn) were determined using the Atomic Absorption Spectrometer. Results confirmed the presence of heavy metals in this order Fe>Zn>Mn>Cu>Pb>Ni>Co>Cr>Cd. The concentrations of the examined heavy metals across the locations were lowest in CL except Ni which was lowest in FE and LF (0.03mg/kg). While there was no significant difference in the concentrations of Cd, Co, Cr, Cu, Mn, Ni, and Pb among locations, both Fe (66.00mg/kg) and Zn (64.33mg/kg) were significantly higher in ATK than in the other locations. The contamination factor suggests that ML (C2), FE (C3) and LF (C3) were moderately contaminated while AKT (C5) was seriously contaminated. The index of geo-accumulation revealed that FE (Igeo4) and ML (Igeo4) are moderate to severely polluted, LF (Igeo5) was severely polluted and AKT (Igeo7) was extremely polluted with the assayed metals. The difference in the occurrence of anthropogenic activities was seen to be the major factor responsible for the variations in the concentration of heavy metals accumulated by the mosses.
