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 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...

Current ocean color sensors, for example SeaWiFS and MODIS, are well suited for sampling the open ocean. However, coastal environments are spatially and optically more complex and require more frequent sampling and higher spatial resolution sensors with additional spectral channels. We have conducted experiments with data from Hyperion and airborne hyperspectral imagers to evaluate these needs ...

There has been a significant investment in research to define exposures and potential hazards of pharmaceuticals in freshwater and terrestrial ecosystems. A substantial number of integrated environmental risk assessments have been developed in Europe, North America and many other regions for these situations. In contrast, comparatively few empirical studies have been conducted for human and vet...
