Plant species act as natural bioindicators of atmospheric pollutants. Plants can be used as bioassay systems for monitoring atmospheric pollutants. Plant injury symptoms, altered growth and reproductive pattern, changes in yield and/or productivity, and changes in species distribution can be used singly or in combination as monitoring devices. The results must be accepted as semiquantitative, b...

Several studies carried out after the Chernobyl nuclear accident in 1986 showed that lichens and mosses are suitable bioindicators of the fall-out, given their long life expectancy. Cs-137 activities were measured in different mosses, epigeic and epiphytic lichens, collected from three sampling sites from Koppl, in the Salzburg province and the effective and biological half-time of Cs-137 were ...

Man made electromagnetic irradiation and fields cover now the globe due to the recent extensive propagation of mobile telephony. The increased load affects animals and also plants. Especially birds have been studied. Humans are also sensitive. They are good bioindicators as epidemiological methods are available. Humans can also report symptoms which cannot be directly measured with presently av...

Acer pseudoplatanus L., Acer platanoides L. and Betula pendula Roth. have been studied under the urban pollution in Sofia during 3 years period. The aim of the study was, by statistical multifactorial analysis, to assess the value changes in morphological parameters of species under air pollution and potential for species usage as bioindicators in observed regions. The statistical analysis incl...

Aquatic oligochaetes are well recognized bioindicators of quality of sediments and water in watercourses and lakes. However, the difficult taxonomic determination based on morphological features compromises their more common use in eco-diagnostic analyses. To overcome this limitation, we investigated molecular barcodes as identification tool for broad range of taxa of aquatic oligochaetes. We r...

a r t i c l e i n f o In a global assessment, canonical correspondence analysis (CCA) and partial CCA were used to ordinate Lake Huron phytoplankton abundances from June and August 1991 and environmental variables. June taxa were associated with NO 3 and chloride, while August taxa were associated with SiO 2 and temperature, and to some degree, with TSP and NH 3. in August reflecting seasonal c...

The analysis of anthropogenic pressure at urban territories has been conducted. The advantages of bioindication methods have been considered. Based on presented requirements to biomonitoring organization the most appropriate bioindicators for urban areas have been chosen. The methods of conduction and results interpretation approaches of plant bioindication have been described. The complex asse...
