(cest2017_00664) Identification by Geophysical/Geochemical Methods of the Areas Polluted by Anthropogenic Emission of Airborne Elements - a Case Study of City Park in the Vicinity of a Steel Plant, Southern Poland

摘要

The recognition of a hazard to human health and the environment from the emissions of airborne pollutants resulted in the adoption of the Convention on Long-Range Transboundary Air Pollution (CLRTAP, 1979) and EMEP co-operative program. Extensive efforts have been undertaken to improve identification of soil contamination with airborne pollutants, in particular with potentially toxic elements (PTEs). An extremely useful, easy-to-use and reliable tool widely investigated for over two decades, is a geophysical method of screening soil pollution with PTEs by surface measurements of magnetic susceptibility к. The extensive works on the method resulted in the development within the Polish-Norwegian IMPACT project (2014-2016) of an international standard ISO/CD 21226 (adoption procedure pending). Here, the use of this method is exemplified in a case study on assessment of soil pollution with PTEs in the city park area in the vicinity of a steel plant operating since 1976. The spatial distribution of magnetic susceptibility in the area indicated high pollution with PTEs in the whole area, with two centres of maximum к values. These data were in conformity with concentrations of PTEs in soils in the area, in particular of Cd, Zn and Pb that occurred in concentrations posing threat to the environment.
