Argentina and Uruguay – January 26th, 2013

The Río de la Plata is a complex water system that connects the del Plata Basin with the Atlantic Ocean. Streams flow from southwest to northeast discharging along the coast of the Río de la Plata Estuary.

Its southwestern coastal sector holds densely populated areas (here, the city of Buenos Aires is visible as a large grey area) with tributaries running across them, which are also receptors of different discharges of pollutants. Human activity is the cause of serious pollution of surface waters, sediments and soils due to point and non-point industrial, agricultural and urban sources.

Results of recent studies show high burdens of different chemical loads in tributaries such as Riachuelo and Canal Oeste. Concentration levels of pollutants are within ranges expected to produce biological effects on aquatic biota, pointing to the need for mitigation interventions (click here for more information).
