Current methods to estimate exposure of wildlife to pesticides from diet depend on a database of published residue concentrations on crop plants normalized to a standard application rate to obtain a residue from a unit dosage (RUD). This database, first published in the early 1970s, was updated in the 1990s. For each category of crops, maximum and mean residues are determined and used to extrap...

in this study impact of climate change on operation of gorgan rud basin's dams was evaluated. in this regard temperature and precipitation of the basin for 2011-2035 periods were downscaled using sdsm model and cgcm3-a2 outputs. results showed that annual temperature would increase 0.05°c and annual precipitation would decrease about 4percent. to predict streamflow of the gorgan rud basin ...
