Materials and methods

Principles of method if other than guideline:

The EU samples were obtained during 2001-2 from municipa waste water treatment plants. Each was obtained over a 24-hour period, and preserved by addition of formalin at the time of sampling.
Samples of 4 litres ware obtained and extracted onto a succession of cartridges, followed by solvent elution.
Quantitative analysis of the eluates was by a derivatisation .Liquid-chromatography-mass spectrometric (LCMS) technique.
Samples from Canada were grab samples obtained during August 2003, and were preserved with formalin.

GLP compliance:

not specified

Type of measurement:

other: Concentrations of alcohols and alcohol ethoxylates were measured.

Media:

other: Effluent monitoring of 20 biofilm and activated sludge wastewater treatment plants from Europe and Canada receiving predominantly municipal effluent.
