“…El-Shenaway et al (El-Shenawy et al, 2009 compared a water grab sample extraction (liquid/liquid), Chemcatcher passive sampler, and biosampling with mussels (Mytilus edulis) with a laboratory and field study. The study found that atrazine accumulates in the passive samplers in greater concentration than in the mussels while the mussels were found to preferentially accumulate dieldrin (El-Shenawy et al, 2009). The results from the El-Shenaway et al (El-Shenawy et al, 2009 studies are consistent with the Housatonic River field study.…”
