Modeled versus measured
concentrations of DEHP in PVC flooring
in Switzerland in 2021/2022. Departing from the best-estimate model
configuration (log-normal lifetime distribution of PVC flooring with
mean of 20 years, high DEHP market share, early DEHP phase-out, low
past recycling rates of PVC flooring; orange in all subplots), one
parameter was varied at a time. The exact parameter values for the
modeled system configurations are available from sections 2.2.2 and 2.2.3. The shaded area depicts the concentration range considered
plausible based on the measurement data, extending to plus/minus two-thirds
of the weighted measurement average (section 2.3.1). 15log: log-normal distribution, mean
