The concentra- tions of As were determined using a slurry sampling procedure with hydride generation atomic absorption spectrometry (HG-AAS). The highest concentrations were observed at estuary mouths, and exceeded conservative lower threshold value (Threshold Effects Level; TEL). Due to the oxic conditions and abundance of Mn and Fe (oxyhydr)oxides in the sediments, most inorganic arsenic in the Subaé and Paraguaçu estuaries was present as As (V). Nevertheless, the concentration of As (III) at several loca- tions along the Jaguaripe River were also above the TEL value, suggesting that As may be toxic to biota. In the Subaé estuary, antropogenic activities are the main source of As. At the Jaguaripe and at Paraguaçu estuaries, nevertheless, natural sources of As need to be considered to explain the distribution patterns.Submitted by Rigaud Andréa (andrearigaud16@yahoo.com.br) on 2011-12-06T17:20:29Z No. of bitstreams: 1 __www.sciencedirect.com_....0-S0025326X10003905-main.pdf: 347910 bytes, checksum: 1d4e59328e70eebb899221056ffa5510 (MD5)Made available in DSpace on 2011-12-06T17:20:29Z (GMT).
