Growth rate decreased significantly with increasing sewage concentrations (mainly at unplanted conditions) and longer immersion periods.

A custom cDNA microarray using a universal DNA reference design was used to examine trends of altered gene expression across sewage concentrations, across timepoints, and at the end of the recovery period.

The effect of different sewage concentrations (0, 20, 60 and 100%), vegetation (Bare, Avicennia marina or Rhizophora mucronata) and immersion periods (immersion/emersion period of 12/12 h or 3/3 days just for 100%) conditions were studied for 6 months on survival and growth rates of Terebralia palustris (Linnaeus, 1767).

Furthermore, a review study of the Joint Research Center of the European Commission [10] show that sewage sludge concentrations of NP and the respective ethoxylates in the European Union countries vary over a wide range, and a remarkable decline in NP contamination range is noticeable comparing the latest available data with results from earlier investigations.

It is however possible to make a comparison between measured and modeled sewage effluent concentrations (a state variable in GWAVA that had a country resolution in this study).

These considerations underline the uncertainty in the expected country-level sewage effluent concentrations, and their unmodeled (and largely unknown) variability within countries.
