Radiotracers in the Black Sea: A Tool for Marine Environmental Assessments

Abstract

Post-Chernobyl trends of radioactive contamination of the Black Sea showed a relatively high rate of purification of its waters against soluble and particle reactive radionuclides. The apparent half-lives for the decrease of {sup 137}Cs and {sup 90}Sr concentrations in the central Black Sea waters was around 6 and 8 years, respectively, suggesting an additional {sup 90}Sr input by river runoff. These values, particularly for {sup 137}Cs, are considerably lower than in the adjacent Mediterranean basin ({approx}13 years), which is caused by faster dilution of {sup 137}Cs concentration in the upper Black Sea waters due to strong river discharge, and by loss of {sup 137}Cs via the Bosporus Strait. These factors, together with a higher rate of particle scavenging of plutonium in the mesotrophic Black Sea water, reflect its significant capability for self-cleaning against nuclear and non-nuclear pollutants, which was traced in this study using data on fluxes and time evolution of natural and anthropogenic radioactivity.
