Total mercury (T-Hg) in Anomalocardia brasiliana (Mollusca) under different biological and environmental conditions

The objective was to determine the spatial-temporal distribution of total mercury (T-Hg) bioavailability at the Goiana Estuary using Anomalocardia brasiliana as model organism. Two seasons (rainy in February and dry in August), three habitats of the tidal flats (upper, middle and lower) and two size...
