the usage and production of polychlorinated biphenyls (pcbs) was banned in argentina in2002, approximately twenty to thirty years later than in other countries. a total of 29 sediment samples (upto 14 m deep) were analyzed for a mix of seven individual pcbs in a time series for over more than one year in twelve selected locations, including harbors, recreational docks and several industrialized...

The present-day study of coastal morphodynamics involves a dynamic field of research in which combinations of coastal monitoring, process-oriented laboratory and field work, modelling studies and Data-Model Integration techniques enhance our capabilities to understand and predict coastal systems and their evolution. Innovations in coastal research and coastal instrumentation strongly interact a...

There are major differences in the bioproduction potential of different coastal areas. The aim of this work is to review and discuss simple, operational criteria related to the bioproduction potential of coastal areas and to present and motivate an Index of Biological Value (IBV) for coastal management. This index is based on two key variables, which can be determined easily from bathymetric ma...

Climate change related Sea Level Rise (SLR) increases the vulnerability of coastal ecosystems by posing threat to many coastal cities, urban centres and coastal population in developed as well as in developing countries. Coastal areas are predominantly rich in resources, easily accessible and facilitate infiltration of people and investments. The 8118 km long coastline in India is characterized...

Local jurisdictions’ coastal zone land use plans play an important role in protecting critical coastal resources and ensuring coastal communities’ sustainable development. This study extends the previous national and regional measurement systems to local coastal zone land use planning. This study evaluates 46 California local jurisdictions’ coastal zone land use plans and analyzes the factors i...

since heavy metals are considered as one of the major pollutants threatening, the main goal of this study was to bring out the concentrations of pb, zn and mn in the surface sediments off bushehr in the persian gulf. for this purpose, after collection of samples, the concentrations of the three metals in surface sediments were measured through the atomic absorption. the results were compared wi...

the bahía blanca estuary, located at the atlantic coast of argentina, includes a governmental nature reserve to protect biodiversity, lands and water; however, as the process of industrialization and urbanization is stepping rapidly at the neighbouring area, the potential increase in contaminant loads is a serious concern. after several contaminants surveys at the estuary, no single study has b...

sea shores of gilan province is one off the biggest tourist attractions in iran. this area have valuable forests and grasslands. in addition it provides significant amount of corps like rice, tea, olive. considering this facts, environmental protection of this area must be priority for national government. however waste management instruction have been ratified in iran, there isn’t any specific...
