Download or read book Effects of Aerial Spraying of Forestry Herbicides on Aquatic Ecosystems Part II written by L. Gordon Goldsborough and published by . This book was released on 1986 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of a three-year study examining some potential effects ofherbicide use in forest management on adjacent aquatic ecosystems, baselinephysical and chemical characteristics of 6 small ponds located in the southeastern boreal forest near Pine Falls, Manitoba were monitored in 1985. Surficial sediment samples were collected from each pondand were analyzed for calcium, magnesium, iron, manganese, sulphate, carbonate, nitrate, phosphate, salinity, pH and organic matter content. Surface water samples were collected at weekly intervalsand were analyzed for true colour, pH, conductivity, alkalinity and concentrations of sodium, potassium, calcium, magnesium, iron, manganese, chloride, fluoride, sulphate, ammonia-nitrogen, nitrate/nitrite-nitrogen, total Kjeldahl nitrogen, total phosphorus, silica anddissolved organic carbon. Measurements of water transparency, air and surfacewater temperature and water depth at a fixed location in each pond were alsomade weekly. Climatic datawere collected from a station in the PineFalls townsite.

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

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.

Book Effects of Aerial Spraying of Forestry Herbicides on Aquatic Ecosystems Part V

Download or read book Effects of Aerial Spraying of Forestry Herbicides on Aquatic Ecosystems Part V written by Geoffrey B. Jones and published by . This book was released on 1996 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes a long-term study established to examine the response of forest aquatic vegetation to glyphosate applications at eight small ponds in the south-eastern boreal forest region of Manitoba. The ponds were monitored over 1985-1993, and were grouped into four pairs on the basis of similarities in water chemistry. One pond of each pair was designated as a control while the other received aerial applications of glyphosate. Baseline physical, chemical, and vegetation features of each site were recorded prior to glyphosate application. Following the herbicide treatment, a regular sampling schedule was established to monitor the chemical and physical variables at each site. In addition, weather conditions were monitored during each growing season over the whole study area. Results presented relate to whether glyphosate application affected the water chemistry of the ponds studied.
