Informative eco-geochemical assessment of soil layer pollution in Chisinau during the peak period of industrial activity

We have carried out a retro-assessment of the data on metal pollution of soils in the city of Chisinau dated by the peak of industrial activity in the late 80s of the twentieth century. The proximity of geochemical spectra in soils of industrial areas and in children's institutions was observed. Statistical analysis of the main components indicated a high specialization of metal pollution in the industrial areas. Soil pollution in areas of children's institutions had a clear residential-transport character. The elimination of a multisectoral industrial production, the redevelopment of industrial areas and an increase in traffic intensity in the city over the past 30 years should have led to a significant change in the spatial structure and spectrum of pollution in the city of Chisinau.
