Heavy metal depositions in Austria (2005 collection)

The report “Heavy metal depositions in Austria” shows the concentrations of toxicologically relevant elements in mosses and concludes from this on their entry from the atmosphere. Since 1991, samples have been taken and analysed every five years at 220 sites in Germany. The 2005 collection report covers atmospheric inputs for 14 metals as well as nitrogen and sulphur. Regionally elevated values of individual elements can be found in the Unterinntal, in the Rheintal, around Treibach-Althofen and Reutte. Since 1995, there have been sharp decreases in the deposition of lead (-56%), vanadium (-32%), chromium (-21%) or nickel (-17%), but also local increases in individual elements. The report is a contribution to the monitoring of the UNECE vegetation within the framework of the CLRTAP (Convention on Long-Range Transboundary Air Pollution).《奥地利境内重金属沉积》报告（"Heavy metal depositions in Austria"）测定了苔藓中具有毒理学意义的元素浓度，并据此推断这些元素经大气输入的路径。自1991年起，研究团队每五年在德国境内220个采样点采集样本并开展分析工作。2005年的采样报告覆盖了14种金属、氮与硫的大气沉降输入情况。区域尺度上的元素浓度异常升高区域主要分布在因河河谷（Unterinntal）、莱茵河谷（Rheintal）、特雷巴赫-阿尔特霍芬（Treibach-Althofen）周边以及罗伊特（Reutte）。自1995年以来，铅（沉降量降低56%）、钒（降低32%）、铬（降低21%）与镍（降低17%）等元素的大气沉积量均出现显著下降，但部分元素在局部区域出现浓度升高现象。本报告是《远距离越境空气污染公约》（Convention on Long-Range Transboundary Air Pollution，简称CLRTAP）框架下联合国欧洲经济委员会（United Nations Economic Commission for Europe，简称UNECE）植被监测工作的一项研究贡献。
