Distribution, behavior and toxicity of metals and sulfur in pore water from the surface sediments of Gulf of Cariaco, Sucre state, Venezuela

Because the criterion of sediment quality, derived from the partition equilibrium model, argues that the pore water is a major source of accumulation and toxicity of chemical species in the tissues of benthic organisms, and trying to reproduce the diffusion processes in them, it was considered interesting to study the behavior of metals and sulfur in the pore water of surface sediments of saco Gulf of Cariaco and its absoiption into polyacrylamide hydrogels, crosslinked with N, N metilenbisacrylamide. Total concentrations in pore water ( mu g/L, except S in mg/L) measured by ICP were: Al (173 - 530), Cd (
