Calculate predicted environmental concentrations in sediment from surface +water concentrations

+ +
+
+

Usage

+ 
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 +

+ +
+ +
+

Description

+ +

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

+ +
+ +

Examples

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