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

Examples

PEC_sw_sed(PEC_sw_drift(100, distances = 1), percentage = 50)
