Impact of Industrial Pollution on Radial Growth of Conifers in a Former Mining Area in the Eastern Carpathians (Northern Romania)

The research aims to evaluate the impact of local industrial pollution on radial growth in affected Norway spruce (Picea abies (L.) Karst.) and silver fir (Abies alba Mill.) stands Tarnița study area Suceava. For northeastern Romania, mining operation constituted a hotspot pollution. primary processing non-ferrous ores containing heavy metals form complex sulfides was main cause region from 1968 1990. Air induced substantial tree reduction 1978 1990, causing decline health vitality. Growth located over 6 km source weaker or absent. Spruce trees were much less by phenomenon than trees. We analyzed dynamics resilience indices average found that period which suffered most between 1984. recovery intensively polluted stand observed after 1990s when environmental condition improved because significant air
