title: Baseline trace elements in the seagrass Halodule wrightii Aschers (Cymodoceaceae) from Todos os Santos Bay, Bahia, Brazil.
abstract: Trace elements concentrations (As, Ba, Cd, Cr, Cu, Ni, Pb, V and Zn) were found in samples of Halodule wrightii Aschers (Cymodoceaceae) seagrass from Todos os Santos Bay, Bahia, Brazil by inductively coupled plasma mass spectrometry (ICP-MS). This bay has been impacted by the presence of industrial activity that includes chemical and petrochemical plants as well as an oil refinery and harbor activities located in the north and northeastern area. Samples were collected at 4 stations to evaluate the distribution of element concentrations in this area and under different climatic conditions. The mean concentrations, in mgkg(-1), found in dry tissues for all the studied metals and stations were: As (1.08-5.42), Ba (3.72-32.0), Cd (0.135-1.68), Cr (1.15-10.4), Cu (2.23-13.4), Ni (1.95-9.87), Pb (0.873-5.18), V (3.39-22.4) and Zn (13.1-39.5). Statistical analysis (ANOVA) of the seagrass data showed significant inter-site differences for all elements examined except nickel and vanadium.
