Notes: Values are reported in dry weight concentrations.

Rinsing fiddler crabs of sand and dirt was inadvertently omitted prior to placing them into sample containers.

ATSDR also analyzed fiddler crabs in the Live Impact Area for RDX, 1,3-dinitrobenzene, 2,4-dinitrotoluene, 2,6-dinitrotoluene, 2-amino-4,6-dinitrotoluene, 4-amino-2,6-dinitrotoluene, nitrobenzene, nitroglycerin, 2-nitrotoluene, 3-nitrotoluene, 4-nitrotoluene, tetryl, 1,3,5-trinitrobenzene, and 2,4,6-trinitrotoluene. For all samples, chemicals were found below detection limits.

The US Fish and Wildlife Service also analyzed fiddler crabs in West Vieques for HCB, PCB-1242, PCB-1248, PCB-1254, PCB-1260, PCB-total, alpha BHC, alpha chlordane, beta BHC, cis-nonachlor, delta BHC, dieldrin, endrin, gamma BHC, gamma chlordane, heptachlor epoxide, mirex, o,p'-DDD, o,p'-DDE, o,p'-DDT, oxychlordane, p,p'-DDD, p,p'-DDT, toxaphene and trans-nonachlor. For all samples, chemicals were found below detection limits.

Averages were calculated using detected values only.

Values are reported in wet weight concentrations.

The non-detected results for sixteen iron samples were regarded as unusable during the validation process because iron displayed a strong interference in the analysis of the samples (probably due to the high concentration of calcium).
