The aim of our study was to evaluate the annual dynamics of needle surface wax erosion and wettability in Scots pines exposed to a gradient of industrial pollutants emitted from the main factories of Lithuania: a nitrogen fertilizer factory, an oil refinery and a cement factory. Decreased emissions (in the case of the oil refinery and the cement factory) were reflected in the increased structural surface area (SSA, i.e. area covered by tubular waxes) on the needles. The nearly constant amount of emissions from the nitrogen fertilizer factory within the 1994-2000 period corresponded to negligible annual differences in SSA. Annual changes in the hydrophobicity of needles on the investigated transects were small. Despite the decreased pollution within the 7-year period, industrial emissions are still causing significantly accelerated wax erosion and increased wettability in needles sampled from the stands most heavily affected by pollutants.
我们研究的目的是评估苏格兰松针表面蜡质侵蚀和润湿性的年度动态变化，这些松树暴露于立陶宛主要工厂排放的工业污染物梯度环境中，这些工厂包括一家氮肥厂、一家炼油厂和一家水泥厂。排放量的减少（炼油厂和水泥厂的情况）反映在针叶结构表面积（SSA，即管状蜡覆盖的面积）的增加上。1994 - 2000年期间氮肥厂排放量几乎恒定，这与SSA的年度差异可忽略不计相对应。在所研究样带上，针叶疏水性的年度变化很小。尽管在7年期间污染有所减少，但工业排放仍在显著加速受污染物影响最严重林分中采集的针叶的蜡质侵蚀，并增加其润湿性。
