Any other information on results incl. tables
RS-Freetext:
BHT concentrations determined in River Rhine at Karlsruhe
and Öhningen (Germany, Baden-Württemberg) during July -
December 1990 were consistently below the determination limit of 1 ug/l.
More refined measurements were conducted by the
Baden-Württemberg water authorities in River Rhine at
Mannheim, in River Neckar at Mannheim, and in River Donau at
Ulm during January - December 1991; the determination limit
was in all cases 0.02 ug/l:
Rhine: <0.02-0.09 ug/l
50 percentile: < 0.02 ug/l
90 percentile: 0.08 ug/l
Donau: <0.02-0.16 ug/l
50 percentile: 0.03 ug/l
90 percentile: 0.09 ug/l
Neckar: <0.02-0.09 ug/l
50 percentile: 0.02 ug/l

Applicant's summary and conclusion
- Conclusions:
- At four different locations of Baden-Württemberg (Germany) the concentration of 2,6-di-tert-butyl-p-cresol (BHT) was measured in water. In none of the cases the measured concentration exceeded the given limit of 1 µg/L in the environment (Landesamt für Umweltschutz Baden-Württemberg, 1994).
- Executive summary:
The concentration of 2,6-di-tert-butyl-p-cresol (BHT) was measured in four different environmental locations: River Rhine at Karlsruhe and Öhningen, River Rhine at Mannheim, River Neckar at Mannheim, and River Donau at Ulm (Germany). The measurements were published by Landesanstalt für Umweltschutz Baden-Württemberg in a personal comunication to BUA in 1994. In none of the cases the concentration of the active substance exceeded the limit of 1 µg/L in the environment.
