8.3.1 Ethyl Glucuronide and Ethyl Sulfate Observed Due to Incidental Exposure to Alcohol A very low level of ethyl glucuronide or ethyl sulfate may be observed in blood or urine due to incidental exposure to ethyl alcohol-containing products such as mouthwash and handwash or from the consumption...
Analysis and interpretation of specific ethanol metabolites ethyl sulfate, and ethyl glucuronide in sewage effluent for the quantitative measurement of regional alcohol consumption. Alcohol.: Clin. Exp. Res. 35, 1593-1599.Reid, M. J.; Langford, K. H.; Morland, J.; Thomas, K. V. Analysis ...
In any event, the presence of N-formylmethylamphetamine at the trace level in illicit MA might require cautious interpretation. Kram and Kruegel [64] also report that a compound of MW 239 Da, tentatively identified as N-methyldiphenethylamine, was detected in illicit MA produced by the ...

The effect of the amount of negative charges on the surface of CNWs is estimated through conductometric titration measurements; this method can be utilized to approximate the number of sulfate ester groups on the surface of CNWs. The results are presented in Supporting Material (Fig. S1). To...
HBM-GVs are an easy to handle health-related risk assessment tool for the interpretation of internal chemical burden. For the general population, HBM-GVs were derived for the sum of the major metabolites of the aprotic solvents NMP and NEP, respectively, which are 10 mg/L for children and ...
3 Ethyl sulfate 3.1 In the footsteps of ethyl glucuronide Next to EtG, ethyl sulfate (EtS), appears to offer potential as a biomarker for recent alcohol consumption. Although its window of assessment is similar to that of EtG, there are important differences between the two markers in their ...
