Table notes:
Units = µg.g-1 (Dry Weight) for marine sediments, soils and sludges and µg.l-1 for WWTP influent and effluents.
Samples were collected after primary settlement and after secondary treatment in this case.
In this case, the sediments are marine in origin.
The arithmetic mean C10 concentration is highlighted for quick reference.
Applicant's summary and conclusion
- Conclusions:
- Decan-1-ol was detected at low levels in environmental samples of various media from urban, suburban and rural sampling locations in UK and USA. Concentrations range between 0-2.6 µg/g (dry weight) in WWTP sludges; 0-0.4 µg/g (dry weight) in sediments; 0-0.04 µg/g (dry weight) in soils (arable soil: 0.01 µg/g (dry weight)), with a single outlier of 91.5 µg/g (dry weight) from a conifer woodland soil. The results are reliable and relevant.
- Executive summary:
It is important for context to note the findings from studies in the EU and USA which consistently show that anthropogenic alcohols in the environment are minimal compared to the level of natural occurrence. Using stable isotope signatures of fatty alcohols in a wide variety of household products and in environmental matrices sampled from river catchments in the United States and United Kingdom, Mudgeet al.,(2012) estimated that 1% or less of fatty alcohols in rivers are from waste water treatment plant (WWTP) effluents, 15% is from in situ production (by algae and bacteria), and 84% is of terrestrial origin. Further, the fatty alcohols discharged from the WWTP are not the original fatty alcohols found in the influent. While the compounds might have the same chain lengths, they have different stable isotopic signatures (Mudge, 2012).
