Concentration
Country:
Germany
Location:
Black Forest
Substance or metabolite:
substance
Conc.:
0.02 - 0.38 mg/kg dw
Remarks on result:
other: 1986, soil under trees
Details on results:
Trichloroacetic acid analysis showed concentrations between 0.02 and 0.4 mg/kg soil. Trichloroacetic acid was detected in all studied soil samples of seriously affected forest area. The highest trichloroacetic acid concentrations was achieved in the oldest leaves.

Applicant's summary and conclusion

Conclusions:
Trichloroacetic acid analysis showed concentrations between 0.02 and 0.4 mg/kg soil. Trichloroacetic acid was detected in all studied soil samples of seriously affected forest area. The highest trichloroacetic acid concentrations was achieved in the oldest leaves, from which it is not eliminated because of its persistence.
Executive summary:

Trichloroacetic acid analysis of soil samples from forest areas (from Black Forest, Federal Republic of Germany) with tree damage (more or less pronounced needle loss) was performed. It showed trichloroacetic acid concentrations between 0.02 and 0.4 mg/kg soil. Trichloroacetic acid was detected in all studied soil samples of seriously affected forest area.
