Anthropogenic influence on photosynthetic pigments concentration dynamics was studied in Betula pendula L., Robinia pseudoacacia L. ņą Salix alba L. leaves in conditions of Prydniprovya steppes. The contents of the total (a+b) chlorophylls in all the examined species proved to decrease dramatically in industrially polluted areas. The research showed that atmospheric pollution diminish concentration of certain forms of green pigment in leaves. The species under study can be ranged B. pendula > R. pseudoacacia > S. alba as their sensitivity to anthropogenic influence grows, and the totality of the studied parameters is considered.
