Use of Background Concentrations of Heavy Metals for Regional Monitoring of Soil Contamination by the example of Rostov Oblast

摘要: In the monitoring of soils contaminated with heavy metals, choice target indicators (background or threshold values) is a challenging task. The determination background concentrations practical importance, because pollution clean to levels below maximum permissible concentration (MPC) tentative (TPC) not recorded and, hence, cannot be prosecuted. Background are rarely applied in assessment, they remain unknown most cases. study specially protected natural areas Rostov oblast has revealed regional specificity soil cover—elevated number metals and other trace elements—related their high parent materials. Therefore, it impossible apply current public health standards based on total elements, such as MPC TPC, contamination oblast. use values characterizing seems more promising for this purpose. For an adequate environmental monitoring, data elements virgin slightly transformed should obtained due account diversity including classification position, texture, character
