摘要: 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 the presence industrial activity that includes chemical petrochemical plants as well an oil refinery harbor activities located north northeastern area. Samples collected at 4 stations to evaluate distribution element this area under different climatic conditions. The mean concentrations, mgkg(-1), dry tissues for all studied metals 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), (3.39-22.4) Zn (13.1-39.5). Statistical analysis (ANOVA) data showed significant inter-site differences examined except nickel vanadium.
