Ozone levels in the Jizerske hory Mts. measured at 13 sites by diffusive samplers during the 2006 and 2007 vegetation seasons are presented. A significant ozone gradient (5.4 ppb in 2006 and 4.0 ppb in 2007) per 100 m difference in altitude between 370 and 1,100 m a.s.l. was recorded. High-resolution maps of phytotoxic potential were developed. The AOT40 threshold (5 ppm h) was exceeded over the entire area with the highest levels exceeding this threshold by 12 times in the upper portions of the mountains. Ozone visible injury was evaluated at four of the monitoring sites on seven native plant and tree species. Four species showed ozone-like symptoms, two of which (Rubus idaeus and Fagus sylvatica) were confirmed as ozone-induced. Our results indicate that ambient ozone is likely to have a much lower impact on the Jizerske hory Mts. vegetation than expected, considering the measured ambient ozone exposures and favourable environmental conditions for ozone uptake.
本文呈现了在 2006 年和 2007 年植被季节期间，在 13 个地点使用扩散采样器测量的 Jizerske hory Mts. 的臭氧水平。在 370 米至 1100 米的海拔高度之间，记录到每 100 米高度差的臭氧浓度存在显著差异（2006 年为 5.4 ppb，2007 年为 4.0 ppb）。开发了高分辨率的植物毒性潜在地图。在整个地区，AOT40 阈值（5 ppm h）都超过了，在山区的上部地区，超过该阈值的水平是该阈值的 12 倍。在四个监测点对七种本地植物和树种进行了臭氧可见损伤评估。四种物种表现出臭氧样症状，其中两种（Rubus idaeus 和 Fagus sylvatica）被确认为臭氧诱导的。我们的结果表明，考虑到测量的环境臭氧暴露和有利于臭氧吸收的环境条件，环境臭氧对 Jizerske hory Mts. 的植被的影响可能比预期的要小得多。
