The R package pfm provides some utilities for fate modelling, including simple PEC calculation routines and some routines for dealing with FOCUS pesticide fate modelling tools (currently only TOXSWA cwa and out files), made available under the GNU public license.

The R package pfm provides some utilities for fate modelling, including simple routines for calculating predicted environmental concentrations (PEC) and some routines for dealing with FOCUS pesticide fate modelling tools made available under the GNU public license.

+

More specifically, pfm includes facilities for simple one-box modelling of the saw-tooth-like curves resulting from multiple repeated applications, for calculation of PEC soil based on the 1997 SANCO guidance and the first tiers of the EFSA PEC soil guidance from 2012 and 2015, as well as some functions for calculating PEC surface water. The PEC drift calculations can be based on the Rautmann drift percentiles published by JKI, the exponential formulas published by Rautmann to inter- or extrapolate to arbitrary distances, or on the integrated Rautmann formulas (integrated over the width of the surface water body) used in FOCUS drift calculations.

+

For PEC drainage calculations, the methods used by the UK at tier 1 and by Germany are implemented. For runoff, the German method used at tier 1 is available.

+

The output of FOCUS TOXSWA calculations can be read in, plotted, and evaluated using the TOXSWA cwa class giving maximum time weighted average concentrations and peak statistics way as available when using the EPAT tool.
