				ABSTRACT 
				
				For determination of bio-physiological 
				parameters, fresh leaf material of two tobacco varieties 
				(Prilep P-156/1 and Yaka Yv-125/3) was used. Soil cultures were grown 
				in controlled experimental
				conditions, in a glasshouse of the 
				Institute of Biology (Faculty of Natural Sciences and 
				Mathematics-Skopje). For each treatment ten plants were taken 
				and were treated with four concentrations of heavy metals: CuSO 4 
				x 5H2O 
				(0.25 mg/kg soil, 0.5 mg/kg soil, 1mg/kg soil, 5 mg/kg soil), 
				CdSO4 
				x 
				8H20 
				(0.1 mg/kg soil, 0.2 
				mg/kg soil, 0.4 mg/kg soil and 0.8 mg/kg soil), Pb(NO3)2
				
				(50 mg/kg soil, 100
				 
				
				mg/kg soil, 200 mg/kg soil, 400 mg/kg soil) 
				and the excess concentration (unallowable for global
				use) of   
				Antracol WP-70
				 
				(0.2 
				mg/kg soil, 0.4 mg/kg soil, 0.8 mg/kg soil and 1.6 mg/kg soil).
				
				Antracol WP-70 
				
				
				is fungicide of the
				dithiocarbamate group, 
				with zinc as its basic constituent. In the same time,
				a trial with 
				control group of ten tobacco plants was set up. Of ten fully 
				matured leaves from lower, middle and 
				upper leaf belts was collected for analyses. All analysis was 
				performed in triplicate. For
				the aim of this paper, leaves from the upper belt (III 
				insertion) were used. The accent was put on the
				analyses 
				of chloroplast pigments content (spectrophotometric method of 
				Holm & Wettstein, 1958) 
				
				catalase activity (titrimetric 
				method of Bach & Oparin) and anthocyanins content (spectrophotometry
				at 510 nm).
