1. detecting a state spruce forests with <strong>the</strong> coefficient <strong>of</strong> defoliation and age <strong>of</strong> spruce<br />

accumulating organs.;<br />

2. determination <strong>of</strong> standing timber productivity for basic and anthropogenicallytransformed<br />

spruce on <strong>the</strong> basis <strong>of</strong> regression equation like that log y =a+b log xc<br />

using coefficients obtained, where dependent variable x-d2h, and y-- phy<strong>to</strong>mass<br />

fraction or production;<br />

3. program <strong>of</strong> moni<strong>to</strong>ring observations.<br />

Problems <strong>of</strong> soil science<br />

There was elaborated an idea <strong>of</strong> forming. Al-Fe-humus soil acidity under conditions <strong>of</strong><br />

industrial air pollution by sulphur and heavy metals' compounds. There was<br />

studied a role <strong>of</strong> biogenic acidification and acid formation matters, invaded from<br />

industrial emission, while forming soil acidification. There was recorded a non-line<br />

character <strong>of</strong> changing <strong>the</strong> parameters <strong>of</strong> soil acidification and circulation <strong>of</strong> mineral<br />

elements regarding <strong>the</strong> distance from pollution sources.<br />

There was characterized microbial component biomass, structure and diversity for Al-Fehumus<br />

podzol soils within <strong>the</strong> tundra area <strong>of</strong> <strong>the</strong> Kola Peninsula while defining<br />

biogeochemical functions <strong>of</strong> micro-organisms in maintenance <strong>of</strong> Arctic ecosystems'<br />

homeostasis. There was found out, that biomass <strong>of</strong> Fungi mycelium predominates<br />

<strong>the</strong> bacteria biomass only in cumulative organogenic horizon. There were recorded<br />

some discrepancies in structure <strong>of</strong> microbe component and content <strong>of</strong> dominating<br />

species between Al-Fe-humus podzol tundra and taiga soils.<br />

Problems <strong>of</strong> ecology <strong>of</strong> biological systems<br />

There was studied a mechanism <strong>of</strong> soil microbe component resistance under extreme nature<br />

and technogenic conditions. In ecosystems <strong>the</strong>re is a biological mechanism, which<br />

decreases soil metallo<strong>to</strong>xicosis in a zone affected by large operating smelter. It is<br />

so-called multyfunction ability <strong>of</strong> species, involved in <strong>the</strong> ecosystem, and <strong>the</strong><br />

organisms' ability <strong>to</strong> uptake oligotrophic matter.<br />

It was recorded, that micro-organisms <strong>to</strong>lerant <strong>to</strong> metals are usually <strong>to</strong>lerant <strong>to</strong> acids.<br />

In microbial soil communities, bearing high concentrations <strong>of</strong> heavy metals (1000-2000<br />

mgkg-1 <strong>of</strong> copper and 2000-4000 mgkg-1 <strong>of</strong> nickel ), <strong>the</strong>re predominate acidophile<br />

species <strong>of</strong> micro-organisms.<br />

There were studied physiological and biochemical characteristics <strong>of</strong> p.p.Penicillium and<br />

Phodo<strong>to</strong>rula fungi and <strong>the</strong>ir high immobilization ability for heavy metals ( <strong>to</strong> 60%<br />

<strong>of</strong> copper and nickel from solutions ). Fungi were recommended for biopurification<br />

<strong>of</strong> industrial wastes and given <strong>to</strong> <strong>the</strong> All-Russia Collection <strong>of</strong> Micro-organisms (<br />

Pushchino City )<br />

Trace elements in biology<br />

On <strong>the</strong> basis <strong>of</strong> chemical analysis <strong>of</strong> hair composition <strong>the</strong>re were detected regional<br />

peculiarities <strong>of</strong> micro-element status for <strong>the</strong> children' organism living in <strong>the</strong> cities<br />

not far from smelters in <strong>the</strong> Kola Peninsula. Those peculiarities are characterised by<br />

low levels <strong>of</strong> content <strong>of</strong> many essential trace elements and a slight content <strong>of</strong><br />

regional prior environment pollutants: Ni, Cu., Co.<br />
