Introduction Because its oxidative power, tropospheric ozone is considered, on a large scale, the most harmful pollutant to vegetation (Ashmore, 2005). The exceedances of critical levels set to protect vegetation are quite high and widespread, so that large parts of crops and forests in Europe are exposed to potentially harmful levels of ozone (EEA, 2009). The impact of ozone on vegetation is t...

It was shown scientifically substantiated the use of lesser duckweed (Lemna minor L.) as a test object for environmental monitoring purposes when contaminated with copper (II), iron lead and zinc cations. The influence metal cations in concentration range from 0.1 to 10.0 mg/l on specific growth rate dynamics changes total area leaf blades (fronds) freshwater plants has been studied. that Cu2+ ...

Heavy metals that pose a threat to the environment include lead (Pb), zinc (Zn), copper (Cu), arsenic (As), cadmium (Cd), chromium (Cr), nickel (Ni) and mercury (Hg). Biomonitoring of environmental quality using plants is widely accepted as reliable inexpensive way obtaining information on contamination also by heavy metals. It allows assessment direction changes in natural development prognose...

Based on the collected data diversity of microalgae and environmental indicators in dry wet seasons during 2011–2018, from 45 samples, 59 species were identified ornithological object—Lake Agmon Hula Valley. In samples periphyton microphytobenthos, diatoms predominated. Bioindication analysis statistical mapping revealed most pronounced zones influence lake ecosystem, as well environment that c...

In comparison with the large volume of work on lakes located in lowland territories, only scattered information about their ecosystems was available for foothill (low-mountain) areas, both Russia and worldwide. Foothill differ significantly from high-mountain physical biological properties. May, July September 2022, current state Lakes Beloe Kolyvanskoe studied north-west Altai (Russia). The co...

This article presents the results of research on influence polymetallic-dust aerial emissions pollution levels in soil and plants by heavy metals, which have been under impact “Severonickel” smelter complex Kola peninsula (Russia) for more than 40 years. Research using plant indicators was carried out at monitoring plots years 1980–1999 (with high aerotechnogenic emissions) 2000–2019 low emissi...

Dr Klára Verseghy (1930–2020), a student of the famous Hungarian lichenologist Ödön Szatala, was working as curator lichen collection Natural History Museum, Budapest between 1958 and 1985. She did great development in herbarium arranging registering big collections F. Fóriss, V. Gyelnik Ö. Szatala Zahlbruckner’s system. Separating type specimens she prepared also catalogue 1964.
