The 'NAR-2000' expedition was performed during August-September 2000. The overall programme of work includes: - monitoring of pollution in air, waters and bottom sediments of freshwater lakes, soils and terrestrial vegetation - soil/botanical studies - visual and remote sensing (aerial photos and video surveys) studies of damage to soil and vegetation cover. Samples of river water and bottom sediments from 25 freshwater bodies and samples from 16 terrestrial sites in the area of the Varandey and Toravey oil fields were taken for chemical analyses.
additional parameters in water/sediments/soils: standard hydrochemical indices, non-polar aliphatic hydrocarbons and volatile aromatic hydrocarbons, detergents and individual phenols (alkyl-, chlorine-, and nitro-derivatives)
Varandey and Toravey oil field area (ca. 68-69 N and 57-59 E) air/aerosol - 6 stations, 6 samples for HM (heavy metals), OCs (organochlorines), PCB, PAH river/lake water - 28 stations, 28 samples for O2, BOD, COD, pH, Eh, alkalinity, nutrients, HM, OCs, PCB, OH (oil hydrocarbons), NAH (non-polar aliphatics), PAH, VAH (volatile aromatics), phenols, detergents bottom sediments - 28 stations, 28 samples for GMC (granulometric composition), HM, OCs, PCB, OH, NAH, PAH, VAH, phenols, detergents soil - 16 stations, 16 samples for GMC (granulometric composition), HM, OCs, PCB, OH, NAH, PAH, VAH, detergents terrestrial vegetation - 16 stations, 16 samples for HM, OCs, PCB, PAH
