Results and discussion
Any other information on results incl. tables
Untreated samples of Goch-Nierswalde (1989) were used for preparation of spiked samples. The limit of quantification (LOQ) was 0.01 mg/kg. The average percent recovery found for spiked samples was 80 % for addition levels between 0.01 and 2.0 mg/kg. All recovery values were between 73 and 91 %. Spiked samples were analysed after storage at -20 °C for periods of 9 and 15 months, in order to check for storage effects. Average recoveries were 69 % indicating no major storage effects. Residues of 2,6-dichlorobenzonitrile were found predominantly in the top layer of the soil (0-10 cm) (see Table 2).

The DT50 and DT90 values were determined according to Timme (1986); only for the second year Goch-Nierswalde, the values did not fit.
Applicant's summary and conclusion
- Conclusions:
- Under the conditions of this test, the mean DT50 was calculated to be 35 days and the mean DT90 value was 202 days. The theoretical maximum fraction formation of BAM in these field dissipation studies was 12.04 %.
- Executive summary:
In a GLP compliant field dissipation study conducted in line with non-standardised guideline BBA Guideline Part IV, 4-1, the DT50 and DT90 values of the test material were determined. Under the conditions of the test, the DT50 was calculated to be 35 days and the mean DT90 value to be 202 days. The theoretical maximum fraction formation of the major metabolite in these field dissipation studies was 12.04 %.
