“…Thus, atmospheric N deposition is still considered to be a serious environmental problem that must be solved, i.e. by the reduction of N emissions [9,14,17].…”

“…Thus, it should be mandatory to describe the sampling sites exactly, especially with regard to the distance of the moss sampling or the deposition collectors to trees and canopies. Accordingly, future moss surveys in Europe will be undertaken using a digital questionnaire comprising information and aspects regarding, among other things, vegetation, land use and soil observed at the monitoring sites [9,13,31,32]. The questionnaire was developed within the German moss surveys and adopted to the moss sampling and requirements of other European countries.…”

“…Furthermore, the moss technique enables achieving a high spatial resolution compared to technical deposition samplers. Since 1990, so-called 'moss surveys' were therefore carried out every 5 years in at least 21 European countries at about 7,000 sites [8][9][10]. These surveys enabled mapping the spatial and temporal trends of metal accumulation in Europe [11,12].…”

“…In addition, atmospheric N deposition into Natura 2000 sites was estimated from the data collected in the moss survey in 2005 (median 16.7 kg/ha*a) [15]. As shown by [9,14,16] and [17], the atmospheric N deposition and the enrichment of N in mosses differ considerably on a regional scale.…”

Background: Atmospheric nitrogen (N) deposition into terrestrial ecosystems is frequently considered as a threat to phyto-diversity. In previous investigations, the atmospheric N inputs enriched in mosses were recorded in 2004 as part of a regional investigation at 54 locations in north-west Germany and in 2005 at 726 locations across the whole country. This article deals with a study conducted in 2012 comparing N concentrations in mosses sampled within 30 forest stands and in 26 adjacent open fields in north-west Germany. The N concentration in mosses were determined and, by the use of a regression model, converted to N atmospheric deposition values. These deposition estimations enabled to calculate N critical load exceedances.

“…In at least 21 European countries, moss surveys are carried out every 5 years since 1990, especially focusing on mapping spatial and temporal trends of HM accumulation until 2005 and extended by N and persistent organic pollutants (POP) since then (Harmens et al, 2013;Mohr et al, 2009;Pesch et al, 2008;Schröder et al, 2004;. Adopted in 1998, the Protocol on Heavy Metals of the Convention on Long-range Transboundary Air Pollution (UNECE, 1998) mainly focused on the gradual reduction of HM emissions from different pollutant sources (e.g.…”

The surroundings of the former Kremikovtzi steel mill near Sofia (Bulgaria) are influenced by various emissions from the factory. In addition to steel and alloys, they produce different products based on inorganic compounds in different smelters. Soil in this region is multiply contaminated. We collected 65 soil samples and analyzed 15 elements by different methods of atomic spectroscopy for a survey of this field site. Here we present a novel hybrid approach for environmental risk assessment of polluted soil combining geostatistical methods and source apportionment modeling. We could distinguish areas with heavily and slightly polluted soils in the vicinity of the iron smelter by applying unsupervised pattern recognition methods. This result was supported by geostatistical methods such as semivariogram analysis and kriging. The modes of action of the metals examined differ significantly in such a way that iron and lead account for the main pollutants of the iron smelter, whereas, e.g., arsenic shows a haphazard distribution. The application of factor analysis and source-apportionment modeling on absolute principal component scores revealed novel information about the composition of the emissions from the different stacks. It is possible to estimate the impact of every element examined on the pollution due to their emission source. This investigation allows an objective assessment of the different spatial distributions of the elements examined in the soil of the Kremikovtzi region. The geostatistical analysis illustrates this distribution and is supported by multivariate statistical analysis revealing relations between the elements.
