Widespread changes in water temperatures, salinity, alkalinity and pH have been documented inland waters North America, which influence ion exchange, weathering rates, chemical solubility contaminant toxicity. Increasing major concentrations from pollution, human-accelerated saltwater intrusion contribute to multiple ecological stressors such as changing ionic strength mobilization of mixtures resulting the freshwater salinization syndrome (FSS). Here, we explore novel combinations elements,...
Abstract Factors driving freshwater salinization syndrome (FSS) influence the severity of impacts and chances for recovery. We hypothesize that spread FSS across ecosystems is a function interactions among five state factors: human activities , geology flowpaths climate time . (1) Human drive pulsed or chronic inputs salt ions mobilization chemical contaminants. (2) Geology drives rates erosion, weathering, ion exchange, acidification‐alkalinization. (3) Flowpaths contaminant along...
Understanding transport mechanisms and temporal patterns in the context of metal concentrations urban streams is important for developing best management practices restoration strategies to improve water quality. In some cases, in-situ sensors can be used estimate unknown trace metals or interpolate between sampling events. Continuous sensor data from United States Geological Survey were analyzed determine statistically significant relationships lead, copper, zinc, cadmium, mercury with...
