What's The Latest On Roundup Herbicide?
"brojack" wrote in message ... What I really need to know is its effect on ground water. Jack Water: Solubility: Glyphosate dissolves easily in water. Potential For Leaching Into Ground-Water: The potential for leaching is low. Glyphosate and the surfactant in Roundup are strongly adsorbed to soil particles. Tests show that the half-life for glyphosate in water ranges from 35 to 63 days. The surfactant half-life ranges from 3 to 4 weeks. Surface Waters: Studies examined glyphosate and aminomethylphosphonic acid (AMPA) residues in surface water after forest application in British Columbia with and without no-spray streamside zones. With a no-spray streamside zone, very low concentrations were sometimes found in water and sediment after the first heavy rain. Where glyphosate was sprayed over the stream, higher peak concentrations in water always occurred following heavy rain, up to 3 weeks after application. Glyphosate and AMPA residues peaked later in stream sediments, where they persisted for over 1 year. These residues were not easily released back into the water. There are plenty of other peer-reviewed studies on glyphosate's effects on water...... |
