Railway Urbanozems: Interrelation of Physicochemical and Integral Environmental Indicators

Urbanozems with typical pollution are formed along railways: heavy metals (HM), oil products, anthropogenic organic matter. Depending on the natural zone and intensity of leaching regime, accumulated can have a different effect integral environmental indicators soils – toxicity enzymatic activity. The aim work was to determine influence railway physicochemical characteristics adjacent urbanozems that in southern taiga find out interrelation these catalase activity soil. Samples were taken from surface layer 0-10 cm at distance 50 m west east 100, 500, 1000 it (east). pH, content matter, humus, ammonium nitrogen, mobile forms HM, mortality for Daphnia magna Straus, bioluminescence Escherichia coli Migula, determined samples. It shown levels strongly related railway: Pearson’s coefficients (r) -0.53 (D. magna), -0.69 (E. coli), 0.95 (catalase). However, between total index (TPI) is lower: r=0.50 pair “D. TPI”, r=0.42 “E. r=0.19 “catalase TPI”. Consequently, reactions living organisms response combination pollutants, not one group compounds.
