Trace and major elements were determined by ICP OES. Organic carbon, total nitrogen and sulfur were determined by CNS elemental analyser. Tubes, crabs and polychaetes were important in the retention of trace and major elements. Metals that presented the highest accumulation in polychaetes (i.e. Mg > Al > Fe > Zn > Mn > Co > Cu > Ba > Cr) where the same for crabs (i.e. Mg > Al > Fe > Mn > Co > Zn > Cu > Ba > Cr). High concentrations of Al, Ba, Cr, Mn and Fe, from terrigenous sources, were observed in tubes, which presented accumulation factors up to 81.5 for Mn. Sedentary polychaetes are seen as good biomonitor alternatives for metal contamination studies, because they are one of the most abundant taxon in the benthic system, live in direct contact with sediments, are present in broad distributions and can also handle relatively high concentrations of metals ensuring chronic exposition. The possibility to work with not only the polychaete but also its tube offers advantages compared to bivalves that generally do not accumulate certain metals in very high levels.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2014-05-05T13:23:40Z No. of bitstreams: 1 1-s2.0-S0025326X13004232-main.pdf: 1032500 bytes, checksum: b3231b44a396f3c3f0fe68b8a513929c (MD5)Made available in DSpace on 2014-05-05T13:23:40Z (GMT).
