Abstract: 4 tables. 2 figures. ["By non-parametric correlation analysis significant agreement among the various scales is shown and this strongly supports the inference that lichens actually do respond to sulfur dioxide. For other air pollutants, data are currently insufficient to establish precise sensitivity scales. However, it is demonstrated that pollutant concentrations measured in the field are sufficiently high to adversely affect species that are demonstrably sensitive to fumigation experiments with air pollutants such as ozone, hydrogen fluoride and zinc."]
