PEC_sw_sed: Calculate predicted environmental concentrations in sediment...

In jranke/pfm: Utilities for Pesticide Fate Modelling

Calculate predicted environmental concentrations in sediment from surface water concentrations

Description

The method 'percentage' is equivalent to what is used in the CRD spreadsheet PEC calculator

Usage

PEC_sw_sed(
  PEC_sw,
  percentage = 100,
  method = "percentage",
  sediment_depth = set_units(5, "cm"),
  water_depth = set_units(30, "cm"),
  sediment_density = set_units(1.3, "kg/L"),
  PEC_sed_units = c("µg/kg", "mg/kg")
)

Arguments

PEC_sw	Numeric vector or matrix of surface water concentrations in µg/L for which the corresponding sediment concentration is to be estimated
percentage	The percentage in sediment, used for the percentage method
method	The method used for the calculation
sediment_depth	Depth of the sediment layer
water_depth	Depth of the water body in cm
sediment_density	The density of the sediment in kg/L (equivalent to g/cm3)
PEC_sed_units	The units of the estimated sediment PEC value

Value

The predicted concentration in sediment
