Accumulation of metals in deciduous tree foliage from urban areas in western-south Poland was monitored during the vegetation season of 2000 year. Concentrations of Al, Ba, Ca, Cd, Cr, Cu, Fe, Mg, Mn, Ni, Pb, Sr, Ti and Zn were measured in birch, willow, linden and maple leaves using the ICP-AES method. Seasonal variations of metal concentrations and their relations with sampling site were investigated. The most dynamic accumulation of Al, Cd, Cr, Ni and Pb was observed for examined species. The highest differences in element concentrations for investigated sites were found for Ba, Cd, Mn and Ni. Interelement correlations were investigated. In all foliar samples synergistic relationships between Al-Cr and Ca-Sr were found. Statistically significant negative correlations were observed only for Cd and Ti in birch leaves.
2000年植被季节期间，对波兰西南部城市地区落叶树木叶片中的金属积累情况进行了监测。采用电感耦合等离子体发射光谱法（ICP - AES）测定了桦树、柳树、菩提树和枫叶中铝（Al）、钡（Ba）、钙（Ca）、镉（Cd）、铬（Cr）、铜（Cu）、铁（Fe）、镁（Mg）、锰（Mn）、镍（Ni）、铅（Pb）、锶（Sr）、钛（Ti）和锌（Zn）的浓度。研究了金属浓度的季节变化及其与采样地点的关系。在所研究的物种中，观察到铝、镉、铬、镍和铅的积累最为活跃。在所研究的地点，发现钡、镉、锰和镍的元素浓度差异最大。研究了元素间的相关性。在所有叶片样本中，发现铝 - 铬和钙 - 锶之间存在协同关系。仅在桦树叶中观察到镉和钛之间具有统计学意义的负相关。
