The recovery efficiency of PAHs ranged from 89% to 111% for HS-5 and from 78% to 105% for the spiked samples with relative standard deviation (,RSD,) 3.2%–10.6%. The method detection limits were in the range of 0.5–2.0 ng g −1 dry weight.

18/6/1998, · For spiked sediment samples (+10 ng/g) recoveries of 98−105% (RSD 1−7%) were achieved for all OTs, except for TCyT (51%, RSD 4%). The developed analytical procedures were validated with reference material and applied to various environmental samples, such as fresh- and seawater, field runoff, wastewater, sediments, and sewage sludge.

While injections were not directly repeated, we assessed repeatability by calculating the relative standard deviation (,RSD,) between measured concentrations in parallel incubation bottles. The average ,RSD, for each compound over the first three sampling time points ranged from 0.8% (metoprolol acid) to 23.6% (sitagliptin) with a median of 4.6%.
