ANTHROPIC EFFECTS ON ALKALINE METAL CONCENTRATIONS IN THE REGION OF THE ARAÇÁ STREAM MICRO-BASIN, CANOAS-RIO GRANDE DO SUL. This work presents alterations in the concentrations of alkaline metals sodium, lithium and potassium, in abiotic compartments, at Araçá stream micro-basin, located in Canoas, RS. Its spring is located in a low populational density region and crosses an elevated environmental impacted urban area. Its final course crosses an agricultural area. Samples of atmospheric particulates, macrophites, water and sediments were analyzed. High concentrations of alkaline metals, related with draining of rice fields or with the ground type, as well as correlations among its concentrations with regional activities were verified. Tripogandra diurética has shown bioaccumulation compatible with their concentrations on waters.
