Sampling and analysis
- Analytical monitoring:
- yes
- Details on sampling:
- During the final test samples for possible analysis were taken from all test concentrations and the control according to the schedule below:
Frequency:
1. At the start of the test and after 72 hours from the freshly prepared solutions.
2. At the first renewal (t=24h) and the end of the test from the 24-hour old solutions. In addition, samples were taken from 100 mg/l on day 2 when all fish had died.
Volume :2 ml from the approximate centre of the test vessels
Storage :samples were stored in a freezer until analysis.
Test solutions
- Vehicle:
- yes
- Details on test solutions:
- Preparation of test solutions started with a stock in acetone (SupraSolv., Merck, Darmstadt, Germany) at 1 g/g. Aliquots of 0.2 ml of this stock were added per liter ISO-medium to achieve a loading rate of 100 mg/l. The resulting emulsion was stirred for 2 hours, then stabilized for 30-40 minutes and finally the clear and colourless Water Soluble Fraction (WSF) was siphoned off and used for testing. The lower test concentrations for the final test were prepared by subsequent dilutions of the WSF in test medium.
Test organisms

- Length at study initiation (length definition, mean, range and SD): Final test: 2.5 ± 0.2 cm
- Weight at study initiation (mean and range, SD): Final test: 0.43 ± 0.11 g
- Feeding during test: no feeding
ACCLIMATION
- Acclimation period: At least 12 days after delivery
- Acclimation conditions (same as test or not): same as the test
- Feeding: Daily with pelleted fish food (Trouvit)
- Health during acclimation (any mortality observed): In the batch of fish used for the test, mortality during the seven days prior to the start of the test was less than 5%.
Study design

- Total exposure duration:
- 96 h
Test conditions
- Hardness:
- 180 mg CaCO3 per litre
- Test temperature:
- Between 21.0 and 21.6 ºC
- pH:
- Between 7.5 and 7.9
- Dissolved oxygen:

Measured concentrations:0 - 46 and 100 % of WSF prep. at 100 mg/l
At the start of the first refreshment period actual test concentrations were 3.4 and 7.2 mg/l at 46 and 100% of the WSF, respectively. At the start of the last refreshment period the actual test concentration was 2.1 at 46% of the WSF. During both 24-hour refreshment periods these concentrations remained stable (i.e. 87-90% of initial). Based on these results, the effect parameters were based on average exposure concentrations, i.e. 2.6 and 6.9 mg/l at 46 and 100% of the WSF. - Details on test conditions:

- LC50:Under the conditions of the present test PCP induced no lethal effects in carp at 0.10 mg/l. The 96h-LC50 for carp exposed to PCP was 0.20 mg/l (95 % confidence interval between 0.16 and 0.32 mg/l). - Reported statistics and error estimates:
- The LC50 could not be determined using the maximum likelihood estimation method with the probits of the percentages of dead fish as function of the logarithms of the corresponding concentrations (Finney, D.J., 1971: Probit analysis, Cambridge University Press, Cambridge, U.K., 3rd edition). This was because there was no concentration between the highest concentration (A) at which 0% mortality and the lowest concentration (B) at which 100% mortality occurred. Instead, the LC50 was calculated as (AB)½, with A and B being limits of the 95% confidence interval.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- Under the conditions of the present test SPP100 B7 induced no visible effects in carp at or below 2.6 mg/l (NOEC).
The 96h-LC50 was 4.2 mg/l (95% confidence interval between 2.6 and 6.9 mg/l) and was already reached after 48 hours of exposure.
