Wpływ działalności przemysłowej na drzewostany sosnowe w rejonie Tarnobrzega w świetle analizy dendrochronologicznej

Tree−ring analysis has been used to evaluate the influence of industrial pollution on Scots pine (Pinus sylvestris) growing in the Tarnobrzeg region. 237 samples were taken from stands located in two profiles to picture dependence of health conditions of trees on distance from the emitter. The Tarnobrzeg Sulphur Works was the main source of pollution in that region. Factories in Mielec and Nowa Dęba as well as the Połaniec Power Plant could be additional sources of emission. Response of trees to anthropogenic stress was clearly visible in the years 1970−1990, when growth reductions occurred at the majority of the investigated trees. At the beginning of 1990s the decreasing trend stopped and wider tree−rings could be observed.
