The current quality of the mangrove sediments was evaluated by porewater bioassays using embryos of Crassostrea rhizophorae and by an analysis of benthic macrofauna and its relationships with organic compounds, trace metals and bioavailability. Porewater toxicity varied from low to moderate in the majority of the samples, and polychaetes dominated the benthos. The Grande Island sampling station (Station 1) presented more sandy sediments, differentiated macrobenthic assemblages and the highest metal concentrations in relation to other stations and guideline values, and it was the only station that indicated a possible bioavailability ofmetals. The origin of the metals (mainly barium) ismost likely associated with the barite ore deposits located in the Grande and Pequena islands. These results may be useful for future assessment of the impact of oil exploration in the coastal region.Submitted by Ana Valéria de Jesus Moura (anavaleria_131@hotmail.com) on 2012-03-03T14:30:54Z No. of bitstreams: 1 Integrated assessmentofmangrovesedimentsin.pdf: 762586 bytes, checksum: 0b7a0e338715c220aac68df33b77eb7f (MD5)Made available in DSpace on 2012-03-03T14:30:54Z (GMT).
