Calculate predicted environmental concentrations in soil for a product

+ +
+
+

Usage

+ 
PEC_soil_product(product, rate, rate_units = "L/ha", interception = 0, mixing_depth = 5, tillage_depth = 20, interval = 365, PEC_units = "mg/kg", scenarios = "EFSA_2015")
+ +

Arguments

+
+
product
+
An object of class pp
+
rate
+
Application rate in units specified below
+
rate_units
+
Defaults to g/ha
+
interception
+
The fraction of the application rate that does not reach the soil
+
mixing_depth
+
Mixing depth in cm
+
tillage_depth
+
Periodic (see interval) deeper mixing in cm
+
interval
+
Period of the deeper mixing, defaults to 365, which is a year if +rate units are in days
+
PEC_units
+
Requested units for the calculated PEC. Only mg/kg currently supported
+

Description

+ +

Calculates long term accumulation PEC values. Assumes that the complete load to soil during the +time specified by 'interval' (typically 365 days) is dosed at once. As in the PPR panel opinion +cited below (PPR panel 2012), only temperature correction using the Arrhenius equation is performed. +By default, PEC values for the scenarios as defined in the EFSA guidance +(2015, p. 13) are calculated.
