Evaluation of various bioindication methods of measuring zinc environmental pollution

0
This study was undertaken to assess the potential ability of four distinct bioindication methods to monitor zinc pollution levels. The study area was the region around the town of Olkusz, one of the oldest centres of the metallurgic industry in Europe. The four bioindication methods used for the assessment of zinc levels were the moss–bag method and the measurement of metal accumulation in Pleurozium schreberi moss, silver birch foliage and Scots pine needles. The results are presented in the form of contamination deposition maps generated by the MapInfo software. The spatial distributions of the contamination were strikingly similar despite the range of methods applied and the differences in exposure times of the bioindicator species. The similarities were confirmed using statistical analyses of the results.
