A low cost and portable flow-through passive sampling device (PSD) which is not affected by the flow pattern of the sampled aquatic system was developed. Zn2+ was selected as the target analyte in optimizing and testing the device under laboratory conditions using as the source solution (SS) either Zn2+ solutions or environmental waters, spiked with Zn2+. It was demonstrated that the accumulated amount of Zn2+ in all sampling experiments with the newly developed PSD was independent of the flow pattern of the sampled SS which was in contrast with results obtained with previously developed dip-in and shielded dip-in passive samplers. The flow-through PSD consists of an acrylic-based 3D-printed..View full abstract
