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...
The aim of the present work is to present the history of the bioindication at a glance. The major stages of natural sciences in general and bioindication in detail, starting from the ancient times through middle ages and times of scientific revolution to the present time are shown, as well as the past and present examples of using living organisms (especially lichens) to the indication of envir...
After considering the particular problems of atmospheric pollution in megacities, i.e. agglomerations larger than 5 mio. inhabitants, with urbanization of World's population going on steadily, possibilities of active biomonitoring by means of green plants are discussed. Based on specific definitions of active and passive bioindication the chances of monitoring heavy metals in Sao Paulo megacity...
Radiation exposure leads to a large number of victims who seek medical help in the first hours. To provide medical care, it is necessary to correctly establish the fact and dose of radiation by bioindication and biodosimetry methods. Lymphocytes containing nuclear anomalies are easily detected cells of peripheral blood and are suitable as objects of bioindication in the case of radioactive expo...
Comparative analysis of water from natural reservoirs located near a place of the underground nuclear explosion with rock outburst (Perm region) and the radium production industry storage cell (Komi Republic) with contrast levels of radioactive and chemical contamination was performed for the first time using bioindication and chemical analysis. Bioindication was carried out with anaphase-telop...
Private vegetable gardens are often contaminated with elevated levels of heavy metals (HM). Bioindication, using the visible symptoms developing in leaves, can provide simple, cost-effective and reliable detection of soil pollution. In this experiment five species of vegetables from different families were exposed to soil contaminated with HM dust given as copper / zinc / cadmium/ lead = 640 /3...

In the modern era of urbanization, air pollution is becoming a significant cause changes in health population. The contribution complex atmospheric pollutants to state urban environment can be assessed by bioindication method. article, this done using fluctuating asymmetry leaf blades silver birch on example one and half million city Novosibirsk rural settlement located 50 km away. an industria...
Carabid beetles (Coleoptera, Carabidae) are one of the most studied soil groups in relation to heavy metal (HM) accumulation and use for bioindication of environmental pollution. Accumulation of Zn and Cu in carabid beetles was species-, sex- and trophic group-specific. No differences were found in HM contents between omnivorous and carnivorous species. The use of carabid beetles as indicators ...
