Review of polyoxymethylene (POM) passive sampling methods for quantifying freely‐dissolved pore water concentrations of hydrophobic organic contaminants

by John Wiley & Sons, Ltd.  (Feb. 21, 2015)

Methods involving polyoxymethylene (POM) as a passive sampler are increasing in popularity to assess contaminant freely‐dissolved porewater concentrations in soils and sediments. These methods require contaminant‐specific POM‐water partition coefficients, KPOM. Specific methods for determining KPOM perform reproducibly (within 0.2 log units). ...

Three seabird species, Common eider (Somateria mollisima), European shag (Phalacrocorax aristotelis aristotelis), and European herring gull (Larus argentatus), were selected to survey for a broad range of legacy and emerging pollutants to assess chemical mixture exposure profiles of seabirds from the Norwegian marine environment. A total of 201 ...

Quantifying natural variability as a method to detect environmental change: Definitions of the normal range for a single observation and the mean of m observations

by John Wiley & Sons, Ltd.  (Feb. 5, 2015)

The normal range has been defined as the range that encloses 95% of reference values; in practice this range has been defined as the reference mean ± 2 standard deviations. When sample sizes are small and reference data are not normally distributed, the mean ± 2 standard deviations do not enclose 95% of data values. Prediction intervals ...
