Analyse TOXSWA output

-

Read in and analyse a cwa file:

-
library(pfm)
-
## Loading required package: R6
-
example_cwa <- read.TOXSWA_cwa("00003s_pa.cwa")
-plot(example_cwa)
-

Calculate PEC soil

-

Simple PEC soil calculation for an application rate of 100 g/ha and 25% interception, assuming complete mixing into 5 cm and a soil bulk density of 1.5 kg/L, output in mg/kg:

-
PEC_soil(100, int = 0.25)
-
## [1] 0.1

PEC surface water due to drift

-

Initial PEC values for an application of 100 g/ha in the vicinity of a 30 cm deep water body are obtained using
