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 The percentage in sediment, used for the percentage method The method used for the calculation Depth of the sediment layer Depth of the water body in cm The density of the sediment in L/kg (equivalent to g/cm3) 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)#>      1 m
#> 2.130769
