    Emissions of organic matter

    The emission of organic matter is a key environmental problem. Among the pollutants mentioned are Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Total Organic Carbon (TOC). BOD, COD and TOC are key indicators of the oxygen content of water.

    Exceedance of air quality limit values in urban areas

    The indicator shows the fraction of the EU-28 urban population that is potentially exposed to ambient air concentrations of certain pollutants (PM2.5, PM10, O3, NO2, SO2 and B(a)P)) in excess of the EU limit or target values (EU, 2004, 2008) set for the protection of human health; and to concentrations of these pollutants in excess of the WHO Guidelines (WHO, 2000, 2006).

    It also shows the evolution of urban background levels of PM2.5, PM10, O3 and NO2 at the European level.

    Soil erosion by water

    EU-wide estimates of erosion are based on modelling studies. Most models contain a rainfall erosivity factor and a soil erodibility factor that reflect average precipitation conditions. Typical values for these factors may inadequately represent the impact of extreme rainfall. Therefore, the uncertainty of modelled erosion risk is high, especially at local level.

    Physical Trade Balance (PTB)

    The trade surplus or deficit of material resources within an economy, calculated as imports minus exports of raw materials and manufactured products.

    Adjusted net savings, including particulate emission damage (current US$)

    Adjusted net savings are equal to net national savings plus education expenditure and minus energy depletion, mineral depletion, net forest depletion, and carbon dioxide and particulate emissions damage.

    Adjusted savings: natural resources depletion (% of GNI)

    Natural resource depletion is the sum of net forest depletion, energy depletion, and mineral depletion.

    Domestic Extraction (used/unused/total)

    The indicator measures the flows of raw materials extracted or harvested from the environment.
    The sub-cathegory ‘unused extraction’ refers to materials that are not economically used for further processing (e.g.unused residuals of biomass extraction).
