TAILIEUCHUNG - Health effects due to motor vehicle air pollution in New Zealand

Stable sulfur isotope ratios in combination with multi-element analysis of lichens were used to examine the influence of emissions from two coal-fired power plants in the Yampa Valley on pollutant deposition in the Mt. Zirkel Wilderness of northern Colorado (Jackson et al. 1996). Coal-fired power plants typically emit SO2 with a stable isotope ratio 34 S/ 32 S characteristic of the coal combusted. Stable S-isotope ratios in the beard lichen, Usnea, were significantly heavier (more positive) in the wilderness and nearby sites compared to more distant regional sites and corresponded well with sulfur isotope ratio found in snow in the same. | Health effects due to motor vehicle air pollution in New Zealand Report to the Ministry of Transport .
