Results from the pilot at Tilburg

The focus of the pilot was on the development of a practical framework for the application of biological test methods in a Triad approach. Consequently, the selection of tools for the assessment was based on scientific and pragmatic arguments, for instance by focusing on readily available techniques for determination of the concentration of contaminants in pore water and readily available biological tests such as simple bioassays and the monitoring of soil organisms. [Pg.282]

The three fields (A, B and C) clearly demonstrated a trend in contamination levels for most metals, both for total and pore water concentrations (Table 9.2). Chromium concentrations were above the intervention values (IV) for soil. Copper and zinc concentrations were slightly lower than the IV, still indicating significant contamination. Soil pH was similar at all locations, but organic matter content was higher for field C, corresponding to the former inlet of the sewage. [Pg.282]

The toxicity in the soil samples of field A, B and C was determined using three bioassays (Table 9.3). For the Microtox measurements, toxicity was the lowest [Pg.282]

Tilburg sewage fields Sample A Sample B Sample C [Pg.283]

A variety of ecological parameters were determined (Table 9.4). Many parameters differed from the reference sample of field A (like the pollution-induced community tolerance (PICT) results) and showed an increase compared with the reference field, but this can be attributed at least partly to increased organic carbon [Pg.283]
