Study design
- Details on sampling:
- Location:
- Year (performance): 1988 (April - June) - Sampling:
- Geographic coordinates: Soil of 12 monospecific forests in central Spain
- Known emission sources near sampling site: -
- Period of sampling: April- June 1988

Results and discussion
Concentration
- Country:
- Spain
- Location:
- central Spain
- Substance or metabolite:
- substance
- Conc.:
- > 0.8 - < 1.1 other: chromatographic area
- Details on results:
- 1,2,3,4-tetrahydronaphthalene was found in 2/12 soil samples (both from below stone pines) and 0/3 plant samples. Concentrations were 0.8% and 1.1% of the total chromatographic area. Information is insufficient for calculation of mg/kg soil.
Applicant's summary and conclusion
- Conclusions:
- The analysis of samples from 12 soils obtained from mediterranean forests in Spain reveal the presence of Tetrahydonaphthalene at levels betwen 0.8 and 1.1% of the cromatographic area.
- Executive summary:
The analysis of free lipids in12 soils from three representative Mediterranean forest has been carried out. Up to 60 major cyclic compounds were identified including naphthalens and decalins.
Tetrahydronaphthalene was found at levels betwen 0.8 and 1.1% of the total chromatographic area. Information is insufficient for calculation of mg/kg soil.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
