Calculate initial predicted environmental concentrations in surface water due to drainage using the UK method

+ +
+
+

Usage

+ 
PEC_sw_drainage_UK(rate, interception = 0, Koc, latest_application = NULL,
+  soil_DT50 = NULL, model = NULL, model_parms = NULL)
+ +

Arguments

+
+
rate
+
Application rate in g/ha
+
interception
+
The fraction of the application rate that does not reach the soil
+
Koc
+
The sorption coefficient normalised to organic carbon in L/kg
+
latest_application
+
Latest application date, formatted as e.g. "01 July"
+
soil_DT50
+
Soil degradation half-life, if SFO kinetics are to be used
+
model
+
The soil degradation model to be used. Either one of "FOMC", +"DFOP", "HS", or "IORE", or an mkinmod object
+
model_parms
+
A named numeric vector containing the model parameters
+
+ +
+

Value

+ +

+The predicted concentration in surface water in µg/L +

+ +
+ +
+

Description

+ +

This implements the method specified in the UK data requirements handbook and was checked against the spreadsheet +published on the CRC website

+ +
+ +

Examples

+ 
PEC_sw_drainage_UK(150, Koc = 100)
