Calculate predicted environmental concentrations in surface water due to drift

+ +
+
+

Usage

+ 
PEC_sw_drift(rate, applications = 1, water_depth = 30,
+  drift_percentages = NULL, drift_data = "JKI", crop = "Ackerbau",
+  distances = c(1, 5, 10, 20), rate_units = "g/ha", PEC_units = "µg/L")
+ +

Arguments

+
+
rate
+
Application rate in units specified below
+
applications
+
Number of applications for selection of drift percentile
+
water_depth
+
Depth of the water body in cm
+
drift_percentages
+
Percentage drift values for which to calculate PECsw. +'drift_data' and 'distances' if not NULL.
+
drift_data
+
Source of drift percentage data
+
crop
+
Crop name (use German names for JKI data), defaults to "Ackerbau"
+
distances
+
The distances in m for which to get PEC values
+
rate_units
+
Defaults to g/ha
+
PEC_units
+
Requested units for the calculated PEC. Only µg/L currently supported
+
+ +
+

Value

+ +

+The predicted concentration in surface water +

+ +
+ +
+

Description

+ +

This is a basic, vectorised form of a simple calculation of a contaminant +concentration in surface water based on complete, instantaneous mixing +with input via spray drift.
