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%.

Mean recoveries for field spikes averaged 80% and 93% for spring and fall, respectively (n = 24 for each season; ,RSD, < 25%). Mean relative percent difference between field

According to the statistical data estimated by local government, the sedimentation rate is about 10 cm–60 cm a year for different river. Moreover, the sampling tool is the grab sampler, so the ,sediment, samples can be used as representative samples of different seasons. Surface ,sediment, sampling was collected by grab sampler.
