Abstract
Requirements in the European Water Framework Directive include monitoring of priority
substances in the aquatic environment. Use of passive samplers for monitoring purposes in the
highly dynamic storm sewer systems is limited by the time-proportional sampling adopted by
the majority of the available samplers. This paper reports the preliminary results from work
with the SorbiCell passive sampler, which samples runoff with a velocity-proportional
approach. The inlet and outlet of a retention pond was monitored by using autosamplers and
SorbiCell passive samplers. Total concentrations of PAHs in samples from the autosampler
ranged from LOD - 0.63 μg/L in the pond inlet and LOD - 0.08 μg/L in the outlet. Dissolved
concentrations of PAHs measured using the passive samplers at the inlet varied from LOD -
0.93 μg/L. Dissolved copper concentrations ranged from 4.7-22 μg/L according to the data
from the autosamplers and between 18-43 μg/L according to the passive samplers. Dissolved
lead and zinc concentrations ranged from 0.3-35 μg/L and 36-122 μg/L respectively. The
different sampling techniques were compared by using an integrated stormwater quality
model. Representative samples can be obtained by using both sampling methods after an
accurate definition of the sampling configuration (sampling frequency, flow velocity around
the sampler).
