Effects of road salt on photosynthetic and enzyme activity of stream biofilms
Abstract
dc:description.abstract<p>Road salt application and salt-laden run-off are common, yet little information exists about its influence on periphyton. I measured extracelluar enzyme activity and photosynthetic activity of natural winter stream periphyton communities under various short-term laboratory salt exposures. The results of this study suggest that short-term exposure to increased concentrations of salt did not affect extracelluar enzyme activity but could temporarily reduce the photosynthetic activity of the periphyton. Further work will be necessary to understand the longterm effects of increased salt concentrations on periphyton and extracellular enzyme activity.</p>
