Abstract:

this study examined the spatial and temporal variations of six important parameters of the salt accumulation process in water samples collected along section urban of contas river. the na+, k+, ca2+ and mg2+ concentrations were determined by faas. the conductivity, total dissolved solids, na+ and ca2+ presented the largest seasonal and spatial variations in the urban area demonstrated that are appropriate indicators of urban contamination. the readily soluble salts in drainage urban, contribute for the degradation of the water of rivers located in semi-arid zones.
