Atmospheric Heavy Metal and Nitrogen Deposition Using Mosses as Biomonitors

The Special Issue “Atmospheric Heavy Metal and Nitrogen Deposition Using Mosses as Biomonitors” includes a collection of papers related on aspects of passive moss biomonitoring of air quality in various regions of the world regarding the pollution sources of potentially toxic elements, heavy metal air pollution in the lockdown period due to the COVID-19 pandemic, trends in element atmospheric deposition, and relevance for ecological integrity and human health. Most of the studies were carried out in the framework of the International Cooperative Program on Effects of Air Pollution on Natural Vegetation and Crops (ICP Vegetation) of the United Nations Economic Commission for Europe (UNECE)
