This -defaults to lab in this implementation, in order to avoid -double-accounting for mobility. If comparability with the original GUS -values given by Gustafson (1989) is desired, non-normalised first-order -field half-lives obtained under actual use conditions should be used.</dd> - <dt>redox</dt> - <dd>Aerobic or anaerobic degradation data</dd> - <dt>sorption_value</dt> - <dd>Which of the available sorption values should be used? -Defaults to Kfoc as this is what is generally available from the European -pesticide peer review process. These values generally use a reference -concentration of 1 mg/L in porewater, that means they would be expected to -be Koc values at a concentration of 1 mg/L in the water phase.</dd> - <dt>degradation_aggregator</dt> - <dd>Function for aggregating half-lives</dd> - <dt>sorption_aggregator</dt> - <dd>Function for aggregation Koc values</dd> - <dt>x</dt> - <dd>An object of class GUS_result to be printed</dd> - <dt>digits</dt> - <dd>The number of digits used in the print method</dd> - </dl> - - <div class="Value"> - <h2>Value</h2> - - <p><dl> -A list with the DT50 and Koc used as well as the resulting score - of class GUS_result -</dl></p> - - </div> - - <div class="Description"> - <h2>Description</h2> - - <p>The groundwater ubiquity score GUS is calculated according to -the following equation -$$GUS = \log_{10} DT50_{soil} (4 - \log_{10} K_{oc})$$</p> - - </div> - - <div class="References"> - <h2>References</h2> - - <p>Gustafson, David I.
