Download or read book Effects of Aerial Spraying of Forestry Herbicides on Aquatic Ecosystems Part III Bioassay of the Effect of Glyphosate on Carbon Fixation by Intact Periphyton Communities written by D. J. Brown, (Dennis James) and published by Water Standards and Studies Section. This book was released on 1987 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of a three-year study examining potential effects of herbicide use in forest management on adjacent aquatic ecosystems, artificial substrate (acrylic rods) were positioned in shallow water within six experimental study ponds near Pine Falls during late summer. The substrata were permitted to colonize with periphytic algae for a period of 41 to 50 days, after which samples were collected and exposed in the laboratory to concentrations of glyphosate (added as the commerical formulation Roundup) ranging from 0 to 1800 mg/L. Carbon fixation rates during the first four hours after herbicide treatment were measured, and the change in rate relative to untreated controls was used to assess the short-term effects of glyphosate on algal photosynthesis.
