Biological test procedures for assessing the quality of soils and soil materials during on-site-analysis; automation and evaluation software

The developed software model allows for the planning and automation of the analytical process, the documentation of all processing and sample data as well as the assessment and recording of the measured data in accordance with standards. As a result, data for all relevant sample parameters can be collected in a structured way, making risk assessment easier.

Summary

Up to now there have been no biological testing systems which are able to deliver plausible results regarding contaminant levels in the soil and soil materials. This means that qualified risk assessment, requiring a high level of chemical testing and considerable time expenditure, has been the only method available for analysing brownfield sites.
The aim within the framework of this particular project was thus to develop a user-friendly software model for the range of tests required, in order to automate analysis, evaluation and documentation of measured data.

Results:

  • Two software models were developed as BiolaneTM database applications on Interbase databases:
  • The automation software model can be used for the planning and automation of analytical procedures, the documentation of all process and sample data as well as the evaluation of measured data from a range of tests consisting of the DIN umu-genotoxicity test, the Vibrio fischeri luminescence test and microbial ground respiration studies.
  • The assessment software model supports the evaluation of test readings using a structured data collection of ecotoxicological, geochemical, pedological and site-specific sample parameters, the content of which can be subjected to database-typical search and organisational functions while application-specific comparison options are also available. By including comparative data, the interpretation of data in the test report is simplified and less open to criticism, since the basis for comparison also provides an empirical foundation for the interpretation.
