  Rezumat:  The influence of heavy metals from mine spoils (Cavnic, Baia Mare mining area, Romania) on the synthesis and accumulation of photosynthetic pigments and proteins in soybean leaves was investigated. Soybean plants (Glycine max cvs. Agat and Diamant) were grown under field conditions in the following variants: control (unpolluted soil), 50% spoils+50% unpolluted soil, 100% spoils. The accumulation of photosynthetic pigments and proteins in the leaves of soybean plants was estimated in various vegetation stages: the beginning of flowering, the beginning of pod genesis, and the stage of fruit ripening. The amount of photosynthetic pigments in leaves of both soybean cultivars grown in spoil variants decreased. The chlorophylls were more affected than the carotenoid pigments. The plants cultivated in 100% spoils accumulated a high amount of proteins in leaves. The Agat cv. plants contained more proteins in leaves than the Diamant cv. plants, not only for the spoil variants, but for control as well.
