Samples of the lichen Parmelia sulcata Taylor were collected in the vicinity of 17 air pollution monitoring stations in the northern part of Switzerland and its bordering area. Net photosynthesis, dark respiration, and the content of [ S]-sulphate and [ S]-protein after cultivation with SO , as well as the chlorophyll and protein contents were measured. Mean values of dark respiration and protein content were not significantly different in the plant material from the various locations. Most of the mean values of net photosynthesis differed less than the average standard deviation. The rates of sulphate uptake and protein synthesis were lowest and chlorophyll content was highest at the most polluted sites. The values differed by a factor of 3.5-7 between the various locations. Multiple regression analysis gave a linear correlation between the three physiological parameters [ S]-sulphate, [ S]-protein and chlorophyll content and a combination of the annual mean concentrations of the air pollutants NO, NO , SO and O . The highest multiple correlation coefficient (R ) was estimated for chlorophyll (0-84). Its linear correlation coefficient (r) with NO alone was 0.91, and with SO alone 0.85.
在瑞士北部及其边境地区的17个空气污染监测站附近采集了地衣松萝（Parmelia sulcata Taylor）样本。测量了净光合作用、暗呼吸、用二氧化硫培养后的[S]-硫酸盐和[S]-蛋白质含量，以及叶绿素和蛋白质含量。不同地点植物材料的暗呼吸和蛋白质含量平均值无显著差异。大多数净光合作用平均值的差异小于平均标准差。在污染最严重的地点，硫酸盐吸收和蛋白质合成速率最低，叶绿素含量最高。不同地点的值相差3.5至7倍。多元回归分析表明，三个生理参数[S]-硫酸盐、[S]-蛋白质和叶绿素含量与空气污染物一氧化氮、二氧化氮、二氧化硫和臭氧的年平均浓度组合之间存在线性相关性。叶绿素的最高多元相关系数（R）估计为0.84。其与一氧化氮单独的线性相关系数（r）为0.91，与二氧化硫单独的线性相关系数（r）为0.85。
