+\title{Calculate predicted environmental concentrations in soil}
+\usage{
+PEC_soil(rate, rate_units = "g/ha", interception = 0, mixing_depth = 5,
+  bulk_density = 1.5, PEC_units = "mg/kg")
+}
+\arguments{
+\item{rate}{Application rate in units specified below}
+
+\item{rate_units}{Defaults to g/ha}
+
+\item{interception}{The fraction of the application rate that does not reach the soil}
+
+\item{mixing_depth}{Mixing depth in cm}
+
+\item{bulk_density}{Bulk density of the soil. Defaults to 1.5 kg/L, or 1500 kg/m3}
+
+\item{PEC_units}{Requested units for the calculated PEC. Only mg/kg currently supported}
+}
+\value{
+The predicted concentration in soil
+}
+\description{
+This is a basic, vectorised form of a simple calculation of a contaminant
+concentration in bulk soil based on complete, instantaneous mixing.
+}
+\examples{
+PEC_soil(100, interception = 0.25)
+}
