Dust pollution and vegetation health - Sokolov, Czech Republic

This product shows the effect that atmospheric dust deposition, caused by natural processes (e.g., windblown soil particles) or anthropogenic activities (e.g., farming, coal mining, power generation, road traffic), may be having on the health of Norway spruce trees. The aluminium (Al) content was measured in street dust samples collected from tarred or concrete surfaces in the region, while the health of the trees was determined using airborne reflectance data.
For street dust samples collected, the median Al content is 5.3% and the 90th percentile is 6.1%. The Al content in this region is therefore lower than theAl content for European soils, which have a median of 5.8% and a 90th percentile of 8.5% (according to the Geochemical Atlas of Europe). Tree health has been divided into five classes, ranging from the best health (dark blue) to the worst health (dark red). It can be seen that areas of worst tree health
correspond to elevated content ofAl in street dust.
The product relates to indicator D1 Aerosols (particle concentration in off-site air).

 
An example of acid mine drainage contamination potential - Sokolov, Czech Republic

This product assesses the potential effect of acid mine drainage (AMD) on water quality. It shows a potential downstream flow path of AMD contamination from a major overburden dump source.
The flow path was computed using a 5-m Digital Elevation Model.
This product relates to indicator E4 Acid Mine Drainage generation potential (distribution of sulphidic iron minerals).

Soil composition and acid mine drainage producing minerals - Sokolov, Czech Republic

This product shows the composition of soils and assesses how this information could help reduce the potential environmental impact of acid mine drainage (AMD). It includes relative clay-quartz content in the soil and iron oxide minerals mapped in 2009 and 2010 that may be associated with AMD. Clay-rich soils may contain minerals that have the natural ability to neutralise AMD and also be more fertile than quartz-rich soils.
This product can therefore be used to identify areas with good remediation potential.
Possible iron oxide minerals associated with AMD were identified using airborne reflectance data and the soil composition was determined using airborne thermal data.

Spatial distribution of iron oxides possibly associated with acid mine drainage - Sokolov, Czech Republic

This product assesses the potential effect of acid mine drainage (AMD) on water quality. It shows where iron oxides and other AMD-producing minerals occur (in 2009 and 2010) in relation to surface water and where it flows. It can be used to evaluate possible environmental impacts of AMD on surface water quality.
The occurrence of possible AMD is sparse and generally confined to active mining areas and overburden dumps, however some occurrences are close to drainage channels.
Possible AMD-producing minerals were identified for 2009 and 2010 using airborne reflectance data. Regular airborne surveys such as this prove useful for monitoring AMD. Surface water was mapped using airborne thermal data and drainage channels using a 5-m Digital Elevation Model.

Acid mine drainage producing minerals and water quality - Sokolov, Czech Republic

This product assesses the potential effect of acid mine drainage (AMD) on water quality. It shows where minerals associated with AMD occur (in 2009), the dissolved iron (Fe) content in surface water and where water flows. The occurrence of possible AMD minerals and surface water with high Fe content (which is also often associated with AMD) is generally confined to active mining areas and overburden dumps. In some cases, AMD-producing minerals and water with high Fe content occur close to drainage channels.
PossibleAMD-producing minerals and the dissolved Fe content of surface water were mapped using airborne reflectance data, while drainage channels were mapped using a 5-m Digital Elevation Model.
