Abstract: The aim of the study was to determine the state of the environment in Sosnowiec (southern Poland) based on the ratio of air pollution tolerance index (APTI) and the determination of concentrations of selected metals in soil and plant material. The study was conducted in ten stands: five of them were identified as ‘polluted’ and five as ‘clean’ stands. The metal content was evaluated by the atomic absorption method. For APTI calculation, analysis of total chlorophyll concentration and relative water content, the pH of the extract from the leaves was used. Analysis of the bioaccumulation of metals in the leaves revealed excessive concentrations of Pb (32.4 mg kg-1) and Zn (129.78 mg kg-1) at the KWK (coal mine) and Las (forest) stands. Higher capacity accumulation of Pb and Fe was characteristic for Plantago lanceolata. The permitted content of Pb (762.6 mg kg-1) in the soil samples collected at the Cedler stand was exceeded. Elevated levels, higher than the permissible concentration of Cd, were documented in soil samples from most stands within the city. In soil samples collected at the Cedler stand, Cd concentration was almost 15 times higher than acceptable for soil (4 mg kg-1). Based on the scope of the APTI 4.4–9.42 index obtained for the studied species, they should be considered sensitive plants. All selected species can be used as bioindicators for environmental pollution.
