Abstract The article «Assessing the impact of historic coastal proving grounds on sensitive ecosystems: A case study from Dorset, South England» written by A. B. Cundy, M. Smith, I.D. Green, N. Tomlinson, and others were published in Estuarine, Coastal and Shelf Science in September 2012. A.B. Candy and M. Smith work at the University of Brighton. I.D. Green is an associate professor at Bournemouth University. His scientific interests are entomology, ecology and pollution ecology. N. Tomlinson is a member of the Royal Society for the Protection of Birds. The article is developed to the study of waste disposal problems to preserve the coastal ecosystems. The paper describes the potential negative impact of historical landfills on wetland and coastal ecosystems. The aim of this research is to study the degree of contamination by heavy metals of the environment on the example of the landfill and marsh at the Lodmoor. The authors emphasizes despite the fact that landfills are closed, they continue to have a detrimental effect on the environment. In the future, changing physiographic conditions may enhance the migration of heavy metals. Due to sea level rise, there will be a threat of erosion and salinization of territories, which will be the cause of biochemical reactions ecosystems. The article provides an analysis of the concentration of heavy metals in three areas: a swamp, a drain, the edge of a landfill. The concentration of heavy metals is compared to background values. In studies used a set of geochemical methods. X-ray phase method was used to determine the composition of the sediments; factor analysis was used to determine the correlation links between the chemical elements. Geochemical data showed that Pb concentration values twice the background concentration were observed. The concentrations of Cr, Ni, and Zn rarely exceeded the background. Using radiometric dating 137Cr and310Pb, it was found that the maximum pollution occurred in the years 1950-1960, when landfills were opened in Lodmoor. Also, the possibility of future metal migrations is shown by electromagnetic research data. This paper includes recommendation that long term site monitoring of Pb and other pollutants in sediments and water. The article can be of interest to specialists and simply not indifferent people to the problems of environmental pollution.
