| Abstract/Contents: | Explains that "the use of chemical pesticides is generally considered necessary to maintain high turf quality" but "those same toxic properties that provide pest control may be hazardous to ecosystems and human health." States that "the most useful tools for predicting chemical behaviors in the environment are 'fate and transport' models" that "are mathematical equations of chemical transformations and transport that are converted into computer programs that can be run for any chemical or site of interest." Describes volatization of pesticides on turf which "is governed by the same processes that affect water evaporation." Discusses how "it is reasonable that evaporation values from such [evapotranspiration] models could be converted to pesticide vaporization by scaling factors that reflect the differences in chemical properties of water and pesticide." Describes how this theory was used to create a model that was tested in "experiments conducted at the University of Massachusetts's Turfgrass Research Center in South Deerfield" on plots of "well established creeping bentgrass maintained at half-inch mowing height." States that "most results fall relatively close to the line of perfect prediction." States that "based on these results, we are confident that an ET-based approach is a resonable way to estimate pesticide volatilization from turf." Describes how using information regarding vapor pressure, vapor concentrations can be estimated in attempt to determine the hazard quotient of a pesticide. |
