Israeli Experience

A number of marine and coastal pollution monitoring programs were undertaken in Israel since the mid 1970's. The contribution of monitoring to environmental management is discussed in relation to three environmental problems: the presence of tar balls and litter on the coastline and the accumulation of anthropogenic heavy metals in the coastal ecosystem. The results of the monitoring coupled with the results of relevant research were used as a basis for decisions on pollution control and abatement programs and for assessment of their effectiveness.

The accelerated urbanisation without a planning, brought several environmental problems to Rio de Janeiro coastal zone, especially in areas such as Rodrigo de Freitas lagoon, which receives a great amount of untreated sewage every day. To assess the nature, potentially sources and extent of heavy metal pollution in the lagoon, sediments from the surrounding streets, from the entrance of the main canal that drains to the lagoon and from the bottom of the lagoon were collected and analysed by a modified selective extraction procedure in order to study the geochemical partitioning and bioavailability of Zn, Cu, Cr, Ni and Pb in these three compartments. The present study verified an increase in the Cu, Pb and Zn concentrations in the north of the Rodrigo de Freitas lagoon. Despite the different levels of oxidation between the sediments accumulated in the streets and in the bottom of the lagoon, the geochemical partitioning of the heavy metals did not show any pattern of variation for the metals, except for the element Cu. No concentrations were found in the soluble phase of samples collected in the surfacial sediments of the lagoon, suggesting no bioavailability of heavy metals
