“…heavy metals, PAHs or microplastic) [8][9][10] and has been used since the end of 1960s -the studies were initiated by two Swedish scientists [11]. A number of projects have been initiated since that time, which support biological monitoring; one of these is ICP Vegetation, in which most European countries participate and which assesses the influence of air pollution on cultivation and (semi)natural plants [12,13]. Both studies of passive and active biomonitoring evolve, in order to become standardised studies [14,15] which can compete with instrumental methods [16].…”

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.

The aim of this study was to evaluate the use of various indicators in the assessment of environmental pollution and to determine the response of pine to changes of pollution levels. Mezaparks is a part of Riga that has been subject to various long-term effects of atmospheric pollution and, in particular, historically from a large superphosphate factory. To determine the spatial distribution of pollution, moss, pine bark and soil O and B horizons were used as sorbents in this study, as well as the additional annual increment of pine trees. The current spatial distribution of pollution is best shown by heavy metal accumulation in mosses and the long-term accumulation of PO pollution by the soil O horizon. The methodological problems of using these sorbents were explored in the study. Environmental pollution and its changes could be associated with the tree growth ring annual additional increment of Mezaparks pine forest stands. The additional increment increased after the closing of the Riga superphosphate factory.
