摘要: The objective was to estimate the seasonal and inter-tidal variability of dissolved particulate mercury fluxes between Ria de Aveiro (Portugal) Atlantic Ocean. were estimated by means a two-dimensional vertically integrated hydrodynamic model. Results showed that fraction plays an important role in transport while contribution seston always <0.5%. During spring tides, summer, about 2% transported present organic form. mass balance for fractions revealed export Ocean varied with season tidal regime, mainly terms relative importance fractions. An approximate range values annual 42 77 kg shows makes little impact on near shore region recovery lagoon from contamination is likely remain long-term issue.
