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.

“…Cellular H 2 O 2 concentration is widely regarded as the indicator of oxidative stress level, which is commonly quantified by the Amplex Red method . In our experiment, an Amplex ® Red Hydrogen Peroxide Assay Kit (Invitrogen) was used to measure the cellular H 2 O 2 production in C. cladosporioides following the manufacturer's protocol.…”

Moisture is one of the critical abiotic factors that can affect mold growth. Indoor humidity is typically fluctuating, which renders a transient water supply for mold growth. Understanding mold growth under water dynamics and its underlying mechanisms can help in the development of novel and sustainable mold prevention strategies. In this study, pre‐germination and germinated spores of Cladosporium cladosporioides were exposed to daily wet‐dry cycles with different combinations of wetting and drying duration. Afterward, growth delay, cellular H2O2 concentration, and catalase (CAT) activity were measured and compared. We found that under daily wet‐dry cycles, the longer the growth delay was observed, the higher the cellular H2O2 concentration was detected, with the 12‐12 wet‐dry cycle (12‐hour wet and 12‐hour dry) showing the longest growth delay and highest cellular H2O2 production. A positive correlation between cellular H2O2 concentration and growth delay was suggested by Pearson correlation coefficient and linear regression analysis (P < .0001, R2 = 0.85). Furthermore, under daily wet‐dry cycles, molds derived from pre‐germination spores generally exhibited shorter growth delay, lower cellular H2O2 concentration, and higher CAT activity than molds developed from germinated spores. These results together suggest that the growth delay of C. cladosporioides under water dynamics is associated with oxidative stress.

“…Stancheva et al (2010), during their investigation with Salvia officinalis, have reported that high levels of heavy metals contained in soil are efficient generators of toxic oxygen species, which can initiate lipid peroxidation and increase levels of MDA and GSH as a result. According to Aydogan et al (2017), Cu bioaccumulation in two bryophyte species induced an increase of lipid peroxidation levels (MDA) up to 155%.…”

The purpose of this study was to determine the concentration of some metals (Al, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Zn, Ca and Mg) in soil of serpentine and limestone sites, their bioaccumulation and impact on some biochemical parameters in T. luanica, T. kosovarica and T. albanica plants. T. kosovarica and T. albanica grows in serpentine soil, while T. luanica grow in limestone soil. The research showed that concentrations of Cd, Co, Cr, Fe, Mn and Ni were significantly higher at serpentine soil sites in comparison with limestone sites, while concentrations of Pb, Cd, Co and Cr in bulbs, leaves and seeds were under the limit of detection. The concentration of Ni in plant samples of T. kosovarica was significantly higher in comparison with its concentration in T. albanica, but it was under the limit of detection in T. luanica. Moreover, concentrations of Al and Fe in leaves of T. kosovarica and T. albanica were higher in comparison with T. luanica. The concentration of Mg was significantly higher in T. kosovarica and T. albanica than in T. luanica. The daminolevulinic acid dehydratase activity, malondialdehyde and glutathione contents in leaves of T. luanica were higher in comparison with T. kosovarica and T. albanica. In addition, the amounts of total chlorophyll and daminolevulinic acid (ALA) in leaves of T. albanica were higher in comparison with T. kosovarica and T. luanica. Our findings show that target organs of metal accumulation in three Tulip species appears to be leaves [ seeds [ bulbs, while the biochemical parameters show that limestone sites represent a less stressful habitat for growing these plant species in comparison with serpentine sites.
