Study design
- Details on sampling:
- - Geographic locations: Germany. Rivers: Isar, Wupper, Leine, Chemnitz, Teltow-kanal.
- Samples: to avoid masking of the STP-impact by high dilution, relatively small rivers and STPs with a high catchment area were chosen. One of the STPs (Chemnitz) has no biological treatment.
- Period of sampling: the sampling took place between August and Oktober 1993. The samples at the rivers and the STP outflows were taken over a period of 7 days and stabilized by for-malin. Inflow samples were taken on 2 days.
- Sampling: STPs and river's water. In rivers, the samples were collected by regional authorities in the framework of a Tenside-Monitoring study which was coordinated by the TEGEWA.

Applicant's summary and conclusion
- Conclusions:
- The comparison of inflow and outflow demonstrated the elimination of test item by sludge absorption.
The PEC/PNEC ratio does not suggest risk to the aquatic environment. - Executive summary:
Method
As a basis for an aquatic risk assessment of the remaining FWAs a monitoring program was launched to actualize data about environmental concentrations of the most important FWAs (including test substance). The sampling took place at five representative STPs in Germany. The five rivers monitored should give a representative cross-section regarding the geological background and the flow rate. Because of the extremely low predicted concentrations in environmental compartments, especially in surface waters, an analytical method has been developed allowing a reliable, quantitative determination down to 2 ng/L. The sampling concurrently took place with sampling in the framework of a tenside monitoring program in Germany.
Results
The comparison of inflow and outflow demonstrated the elimination of test item by sludge absorption.
PEC/PNEC estimated: 0.002-0.048. The PEC/PNEC ratio does not suggest risk to the aquatic environment.
