“…Bryophytes are efficient capture organisms for wet and dry deposition of heavy metals (Cymerman et al, 2006;Schofield, 2001;Wilkie and La Farge, 2011). In this fine-scale survey of bryophytes on Goujiang karst bauxite, each location received the same input of heavy metal ions from precipitation.…”

“…As they lack stomata, bryophytes are unable to screen airborne pollutants by closing stomata at night or during stress (Bates, 2000;Glime, 2007). Some moss taxa can be used as indicators of specific heavy metals in the substrate (Wilkie and La Farge, 2011).…”

“…Six locations: aluminum mill (1-5), vicinity of miners' living quarters (6-10), aluminum ore sintering plant and waste rock pile (11-15), orchards (16-20), ore stockpile (21-25) and bauxite mine (25-30). and La Farge, 2011;Yang et al, 2011). Bryophytes have been used to monitor the atmospheric deposition of heavy metals in Europe and North America (Berg and Steinnes, 1997;Cymerman et al, 2006;Grodzińska et al, 1999;Jules and Shaw, 1994;Økland et al, 1999;Pakarinen and Tolonen, 1976;Pesch and Schröder, 2006;Shaw, 1994;Smirnov et al, 2004), but they have rarely been used to indicate physiological effects and subsequent abundance changes of moss species.…”

“…The biotas in Svalbard are very sensitive to any harmful human influence because of low productivity and a small number of species (Poikolainen et al 2004). Xenobiotics accumulate and biomagnify at each trophic level and even small amounts influence considerable parts of the ecosystems (Gulińska et al 2003;Birks et al 2004; Wilkie and La Farge 2011). Therefore, examination of metal levels in the Arctic environment is very important for the safety of these special ecosystems (Askaer et al 2008;Kozak et al 2015;Halbach et al 2017).…”

Longyearbyen (Spitsbergen) is influenced by local contamination sources, such as exhausts from power plants, traffic, coal mines, and industrial waste dumps subject to weathering, which threatens soil and living organisms. Therefore, the trace element level in this area needs to be evaluated. The moss Sanionia uncinata and prostrate dwarf-shrub Salix polaris were collected as contamination indicators. Concentrations of Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, and Zn in these species were measured. The tested hypotheses were: in Longyearbyen and its vicinity (1) the moss S. uncinata and the willow S. polaris may be used as phytoaccumulators and therefore as bioindicators and bioremediators of certain trace elements; (2) the moss S. uncinata contains higher concentrations of metals than the willow S. polaris. The soil of Longyearbyen was contaminated with Cd, Co, Cu, Ni, Pb, and Zn. The willow S. polaris may be used in phytoaccumulation and therefore in the bioremediation and bioindication of Cd and Zn from its environment. Stems of S. polaris from Longyearbyen are better bioindicators of Cr, Cu, Hg, Ni, and Pb and poorer bioindicators of Cd, Mn, and Zn than leaves of this species. S. polaris (both stems and leaves) was a better bioindicator of Cd and Zn concentrations than green gametophytes of S. uncinata. S. uncinata was a better bioindicator of Co, Cr, Cu, Fe, Hg, Mn, Ni, and Pb than S. polaris.

“…The unique morphological features, such as unistratose phylloids and uniseriate rhizoids, of different moss species provide them with increased surface area and more volume for high rates of cation exchange. Therefore, mosses are assumed to have high tolerance to heavy metal stress as compared to other taxa [32].…”

Aquatic habitats are very frequently polluted with different kinds of xenobiotics, including heavy metals. For biomonitoring studies of aquatic pollution, algae are frequently used, as they do not contain protective cuticle on the surface of their thalli and can accumulate pollutants over the whole surface of thalli. However, this is a feature of most cryptogams. For this reason, we assessed the sensitivity of the aquatic moss Taxiphyllum barbieri (Java moss) to copper excess in a short-term study. Moss T. barbieri belongs to the common aquatic plants originating from Southeast Asia. To test the sensitivity (or tolerance) of the moss to excess Cu, selected concentrations (50, 250 and 500 µM) were employed in our 24 h studies. Total and intracellular Cu accumulation positively correlated with Cu availability in the water. This total and intracellular Cu accumulation was negatively correlated with decreased intracellular K content. Excess Cu negatively affected the composition of assimilation pigments and soluble proteins. Cu caused increased peroxidation of membrane lipids assessed using TBARS assay. Excess Cu decreased GSH to GSSG ratio and ascorbic acid content. We did not observe phytochelatin synthesis in this moss. The roles of selected amino acids, their intermediates and derivatives, as well as S-containing nucleosides and phenolic acids in Cu homeostasis and toxicity or tolerance were evaluated. We assume that this moss has potential for future employment in water quality evaluation.
