Sediment Data Interpretation, Concentrations and Toxicity (All
Sediment Data Subsections Start with "Sed."):
Sed.Low (Sediment Concentrations Considered Low):
No information found.
Sed.High (Sediment Concentrations Considered High):
Toluene was detected in 21.7 % of urban-bay samples from
the Puget Sound area. The mean concentration was 17.04
ug/kg dry weight (ppb), while the median concentration
was 7.5 ug/kg (ppb) [852].
NOTE: The above values are not normalized for
total organic carbon (TOC) content.
Analyses of sewage sludges from 50 publicly owned
treatment works by the U.S. Environmental Protection
Agency (1985): The mean concentration of toluene was
1,718.8 ppm [347].
