Calculate predicted environmental concentrations in sediment from surface water concentrations

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

PEC_sw_sed(
  PEC_sw,
  percentage = 100,
  method = "percentage",
  sediment_depth = 5,
  water_depth = 30,
  sediment_density = 1.3,
  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 L/kg (equivalent to g/cm3)

PEC_sed_units

The units of the estimated sediment PEC value

Value

The predicted concentration in sediment
