  • a Sigma is the repeatability error for any individual measure and consists of the square root of the mean square error of the one-way ANOVA. Results are expressed as GC/ml for wastewater or GC/g of dry weight for sludge and biosolids.

  • b Samples were concentrated using electropositive filters and organic flocculation.
