Water quality in the lower stretch of the Negro River (Chaco, Argentine). The main physical, chemical and biological characteristics of surface waters were measured between November 1999 and May 2002 in four sampling sites located in the course of Negro River. At sites 1 and 2 wetlands and alluvial forest with low human occupation characterize the bordering landscape. Sites 3 y 4 were affected by domestic and industrial discharges, although in the last years tannin production was working at a reduce volume. The chemical composition of surface water was derived primarily from the rain seasonality and the wash-out of salt rich wetlands soil into the river channel. Conductivity was higher during the dry period than the rain period. Sali...
