Fiddler Crab (U. rapax) tissue, mangrove tissue and sediment from crab burrows were collected in Jobos Bay National Estuarine Research Reserve, Puerto Rico, to quantitate Persistent Organic Pollutants (OCs, PCBs, PBDEs) and selected heavy metals (cadmium, barium, mercury, lead, vanadium, chromium, cobalt, nickel, copper, zinc, arsenic and selenium). Once quantified, the concentrations were applied to a bioconcentration factor equation to determine potential uptake pathways of the target analytes. Bioconcentration factors determined that fiddler crabs were the most efficient at concentrating OC pesticides, while mangroves were the most efficient at concentrating PCBs and heavy metals.
