| Abstract: | The impact of a phosphatic fertilizer plant on the adjacent environment was examined. Selected rare earth elements, heavy
metals and metalloids were determined in substrates and products, waste by-product, and grass and soil samples. Concentration
gradients of elements in grass and soil samples along the southerly and easterly directions were examined and compared with
the content of interior soil and grass samples, substrates, and products. Results were compared with available data on soil
permissible element concentration levels. Two fuzzy principal component analysis (FPCA) methods for robust estimation of principal
components were applied and compared with classical PCA. The efficiency of the new algorithms is illustrated. The investigation
explored the impact of the plant on the adjacent environment. The most reliable results, in good agreement with types of samples,
were produced using the FPCA-O algorithm |
