Popis: The Espí
rito SantoBay is located in Espí
rito Santo state in the eastern part of Brazil. It is surrounded by the city of Vitó
ria on one side and by the Atlantic Ocean on the other. Superficial sediments of Espí
rito Santo Bay were analyzed at 12 (western shallow silt sediments) + 8 (eastern sandy sediments and relatively deep sampling stations) = 20 uniformly distributed sampling points, where geochemical analysis was performed. Nineteen elements were analyzed: Mo, Cu, Pb, Zn, Ag, Ni, Mn, Fe, As, U, Th, Sr, Cd, Sb, Bi, V, Cr, Ba, and Al. This selection was made based on the most representative heavy metals present in this area and according to the results obtained from the geochemical analysis. Their concentrations were compared with metal contamination benchmarks such asscreening quick reference tables (SQuiRTs), effects rangelow (ERL), effects range median (ERM), threshold effects levels (TELs), probable effects levels (PELs), and apparent effects thresholds (AETs). The results indicated that there was no particular pollution condition able to alter the condition of any part of this water body. The authors conclude that the Espí
rito Santo Bay is only moderately polluted, and some elements are virtually absent.
