Correlation of Modelled Atmospheric Deposition of Cadmium, Mercury and Lead with the Measured Enrichment of these Elements in Moss: Measured Accumulation in Moss

The book provides a unique analysis of current air pollution in Germany by correlating results from chemical transport modelling and accumulation monitoring by moss.Results of most recent modelling of atmospheric concentration and deposition of the metal elements Cd, Hg and Pb are compared with the results of technical measurements and bioindication with mosses. These modelling results with status 2020 have a higher spatial resolution of 0.1° x 0.1° than the modelling results valid up to then (50 km x 50 km). This leads to partly slightly higher correlations between the findings of the modelling and those of the moss monitoring. In this study, descriptive and correlation-statistical parameters are calculated, results and recommendations drawn described. A statistically adequately deepened analysis and evaluation of the highresolution modelling results requires additional methodological tools, which are outlined in summary. It is particularly important to link the exposure data from modelling, technical measurements and the findings from moss monitoring with information on the receptors, the ecosystem types. This is the only way to ensure that the results of the present project contribute to a more differentiated assessment of the impacts on ecosystems from atmospheric heavy metal deposition than has been the case to date, thus enabling a targeted further development of risk assessments for German Contents Abbreviations List of Figures List of Tables 1 Background and Aim 1.1 Background 1.2 Aim References 2 Material and Methods 2.1 Data 2.2 Data Preparation 2.3 Methods 2.3.1 Methods of Descriptive Statistics 2.3.2 Correlation Analysis 2.3.3 Analysis of the Distances Between Measuring Points of the Technical and Biological Monitoring of Atmospheric Depositions 2.3.4 Mapping of Spatial Distributions of Deviations of Modelled Atmospheric Metal Concentration and Deposition (EMEP) and Concentration in Moss (MM2015) from the Respective Nationwide Median References 3 Results 3.1 Descriptive Statistics 3.1.1 Measurement Data on Heavy Metal Concentrations in Moss 3.1.2 Modelled Mean Heavy Metal Concentrations in the Atmosphere 3.1.3 Modelled Total Annual Atmospheric Depositions of Heavy Metals 3.1.4 Technical Measurement Data on Mean Atmospheric Heavy Metal Concentrations 3.1.5 Technical Measurement Data on Atmospheric Heavy Metal Depositions 3.2 Correlation Analysis 3.2.1 Correlations Between Modelled Mean Concentrations of Heavy Metals in the Atmosphere (EMEP) and Concentrations in Moss (MM2015) 3.2.2 Correlations Between Modelled Atmospheric Heavy Metal Deposition (EMEP) and Concentrations in Moss (MM2015) 3.2.3 Correlations Between Mean Concentration Values from Technical Measurements of Heavy Metals in the Atmosphere and Concentrations in Moss 3.2.4 Correlations Between Technical Measurements of Atmospheric Heavy Metal Deposition and Concentrations in Moss 3.2.5 Graphical Comparison of the Correlation Coefficients 3.3 Comparison of the Federal and State Air Quality Monitoring Network with the Moss Monitoring Network 2015 3.4 Mapping of Spatial Distributions of Deviations of Modelled Atmospheric Metal Concentration and Deposition (EMEP) and Concentration in Moss (MM2015) from the Respective Nationwide Median 3.5 Summary with Regard to the Objectives and Key Questions of the Study References 4 Conclusions References Appendices: Statistical Data Analyses—Tables, Diagrams, Maps Appendix A: Descriptive Statistics A.1 Measurement Data on Heavy Metal Concentrations in Moss A.2 Modelled Mean Heavy Metal Concentrations in the Atmosphere A.3 Modelled Total Annual Atmospheric Depositions of Heavy Metals A.4 Technical Measurement Data on Atmospheric Heavy Metal Concentrations A.5 Technical Measurement Data on Atmospheric Heavy Metal Depositions Appendix B: Correlation Analysis B.1 Correlations Between Modelled Mean Concentrations of Heavy Metals in the Atmosphere (EMEP) and Concentrations in Moss (MM2015) B.2 Correlations Between Modelled Atmospheric Heavy Metal Deposition (EMEP) and Concentrations in Moss (MM2015) B.3 Correlations Between Mean Concentration Values from Technical Measurements of Heavy Metals in the Atmosphere and Concentrations in Moss B.4 Correlations Between Technical Measurements of Atmospheric Heavy Metal Deposition and Concentrations in Moss B.5 Graphical Comparison of the Correlation Coefficients Appendix C: Comparison of the Federal and State Air Quality Monitoring Network with the Moss Monitoring Network 2015 Appendix D: Map Annex Reference
