In the EU-project FOOTPRINT three pesticide risk assessment and management tools were developed, for use at different spatial scales. The three FOOTPRINT tools share the same underlying science, based on the consistent identification of environmental characteristics driving the fate of agriculturally applied pesticides and their interpretation to parameterise state of the art modelling applications thus providing an integrated solution to pesticide risk assessment and management in the EU.
The farm-scale tool FOOT-FS automatically performs TER calculations for a range of aquatic taxonomic groups and for different temporal percentiles of exposure in an edgeof-field water body. The national/EU-scale tool FOOT-NES produces maps and spatial cumulative distribution functions (CDFs) of Predicted Environmental Concentrations (PEC) and Time-Weighted Average Concentrations (TWAC) in edge-of-field water bodies. With the spatial CDFs, the user can e.g. determine the area percentage of exceedance of a given ecotoxicological threshold. Finally, the catchment-scale tool FOOT-CRS produces temporal CDFs of PECsw at the outlet of a given catchment, for different pesticide input pathways. These temporal CDFs can e.g. be used to determine the return period of a given peak exposure concentration.

Klärschlamm darf nicht auf den Boden
Partizipation betroffener Akteursgruppen zur Minderung der Nitratbelastung des Grundwassers
© Springer Vieweg | Springer Fachmedien Wiesbaden GmbH (10/2020)
Die Nitratwerte im deutschen Grundwasser sind vielerorts seit über 20 Jahren erhöht. Die EU-Kommission beurteilte entsprechende Gesetzesnovellen der vergangenen Jahre mehrfach als unzureichend. Vorgestellt werden Untersuchungsergebnisse dazu, unter welchen Voraussetzungen kleine partizipative Gremien lokal zu einer Einhaltung der Nitratgrenzwerte in ihrer jeweiligen Region beitragen können.
Application of computer modelling for forecasting of contaminants distribution in soil
© Aristotle University of Thessaloniki (6/2009)
An outlook of various methods of computer modeling application for the analysis and forecasting of contaminants migration in the soil is being discussed. A new mathematical model of contaminants transport in near-surface soil layer under non-isothermal conditions is being proposed. The given model takes into account the soil moisture content change effecting the solute transport and sorption owing to evaporation processes and recondensation of water vapor. The article also covers the possibility of hybrid expert systems (HES) application for solving contaminants migration in the soil. Distinguish structure of HES that includes models hybridization is being proposed. On the basis of given methods and models a new software has been developed.
