Resumo: The gradual accumulation of copper and zinc in nurseries for cultivation of shrimp in the state of Cearà was quantified through the analysis of sedimentary profiles collected in nurseries with different times of activity. There was an increase of 52.25% copper in nurseries and 122.4% in the young old. For zinc, the percentage increase was 67.19% in nurseries and 80.66% in the young old. The calculation of enrichment factors for these metals indicates that natural sources of copper are still the most significant for the region. For zinc, the anthropic already beyond the natural sources of this metal. We also examined the temporal variation of concentrations of copper and zinc in samples of shrimp collected in southern Bahia. Concentrations of copper in muscle ranged from 14.7  1.9 to 36.6  2.9 Mg. g-1 (dry weight) and the carapace of 34.2  2.0 to 58.0  4.6 Mg. g-1 (dry weight). For zinc, the concentrations in muscle ranged from 59.3  5.2 to 68.4  3.5 and 29.5  shell of 6.2 to 69.8  12.1 Mg. g-1 (dry weight). Concentrations found differ from those calculated for the low Jaguaribe, demonstrating a regional character of the data.
