Description/Abstract This article presents a study of the possible extent and the dynamics of contamination of lotic ecosystems by lead on the basis of a comparative study of the degree of its accumulation in aquatic plants and those growing near water.^The plants used for this purpose were herbarial and medicinal collections of two higher plant species, yellow pond-lily and marsh trefoil which were made in 1913 to 1915, 1939, 1947, and 1958 in the upper reaches of river Usma` on the territory now known as Lipetsk region and in July to August 1977 to 1980 on the same river in Voronezh reservation territory.^Lead was determined quantitatively by an atomic-absorption method.^Results show that over the interval studied the lead content in the plant samples tends to increase, which indicates that the river has become increasingly contaminated by lead.^World War II activity in this area is responsible for the contamination.^(JMT)
