“…From results of previous studies, addition of 0.75 g NaCl to a 2-mL sample considerably decreases the solubility of SCMAs [ 20 ]. The addition of the same amount was included in the protocol.…”

In this study, a procedure was developed to determine short-chain alkane monocarboxylic acids (SCMAs) in aqueous samples using headspace solid-phase microextraction (HS-SPME) followed by gas chromatography (GC) coupled with mass spectrometry (MS). A Stabilwax-DA capillary column (30 m × 0.32-mm inner diameter, 0.50-μm film thickness) was used for GC separation and a 60-μm poly(ethylene glycol) fiber was used to isolate SCMAs from water and introduce them into the gas chromatograph. Parameters of HS-SPME, analyte desorption, and GC-MS analysis were selected and an analytical procedure was proposed. Limits of quantitation were on the order of about 0.2 mg L-1. As an example of the application of the procedure, SCAMs were determined in municipal wastewater at different steps of treatment.

Greater incidence of storm events, which can lead to greater contamination of surface waters by human and animal faeces, are a predicted feature of climate change in parts of Europe and elsewhere. The aim of theis study was to combine the use of a novel quantitative microbial source tracking (QMST) method with established water quality monitoring procedures during an intense summer storm event in a rural UK catchment, to establish dominant sources of faecal pollution. One-litre grab samples of river water were collected every 12 h for a period of seven days from three sampling sites on the Bevern Stream (a tributary of the Sussex Ouse). All samples were tested for a range of chemophysical and bacteriological parameters, and also for phage-lysis of a human specific strain of Bacteroides spp. GB-124. Presumptive levels of Escherichia coil and intestinal enterococci were statistically significant (p-value <0.05) higher during the storm event, compared with dry weather conditions. Low recorded levels of phages of Bacteroides GB-124 during the storm event, compared with dry weather conditions, support the hypothesis that the predominant sources of faecal material in the river during the storm event were non-human. Using traditional faecal indicator bacteria and a QMST marker during storm events may improve human health protection protocol
