Resumo: We characterized the spatial and seasonal distributions of different phosphorus fractions in surface sediments from the Furo of Muriá estuary by chemical fractionation. Five phosphorus species were successfully separated: phosphorus bound to Fe/Al oxyhydroxides (non-apatite inorganic phosphorus (NAIP) ranging from 164.54 to 280.32 μg g-1), phosphorus bound to calcium (apatite phosphorus (AP) ranging from 63.02 to 102.80 μg g-1), inorganic phosphorus (IP, ranging from 227.21 to 378.61 μg g-1), organic phosphorus (OP, ranging from 30.33 to 135.88 μg g-1) and total phosphorus (TP, ranging from 257.54 to 507.73 μg g-1), in which 88% of TP is constituted by IP. Statistical results showed that seasonality was not a major factor influencing phosphorus concentrations. Considering the classification of estuarine sediment conditions, we can conclude that the TP concentrations found in Furo of Muriá do not yet indicate the risk of environmental deterioration.
