\title{Calculate DTx from parameters of parent degradation models}
\usage{
DTx(type = c("SFO", "FOMC", "DFOP", "HS", "SFORB"), parms, exact = FALSE)
}
\arguments{
\item{type}{Character string specifying the degradation model}

\item{parms}{Named numeric vector giving the kinetic parameters}

\item{exact}{Should we used log(10)/log(2) instead of the widely used value
of 3.32 for backcalculation of DT50 values from DT90 values?}
}
\description{
Calculate DTx from parameters of parent degradation models
}
\examples{
# Check what type of DT50 is given in the bixafen EFSA conclusion from 2012 on p. 42
DTx("HS", parms = c(k1 = 0.0081, k2 = 0.00023, tb = 53))
# We get 1200 days for the time the concentration reaches 50\%, the value of 1235
# was likely based on more digits for the parameters. The half-life corresponding
# to the slow phase is around 3000 days
