Popis:	Compounds of lead and cadmium, possessing high toxicity, a cumulative inhibit production process, reduce a salad biomass gain. Research showed that oppression of root system was shown in reduction of number of small backs, and on the main roots there were necrosis damages. Biomass of green part of salad of a grade of “Lolo Biond” decreased almost by 3 times with increase in the maximum allowable concentration of Pb with 0,5 to 10, and root system by 5 times. Influence of cadmium was even more significant. So biomass of land part of salad of a grade of “Lolo Biond” at presence of cadmium decreased by 7 times, and root system by 10 times in the same the maximum allowable concentration.
