Table 3 degradation kinetics (SFO-kinetic, CAKE model) for different sampling depths at SSS setup

From: Impact of simulated sunlight on the degradation of pendimethalin in surface water in a scale-up experiment in accordance to OECD TG 309

Test setup: SSS (cm) Dis*T50 (days) Dis*T90 (days) Coefficient of determination (r2) Chi2 error (%)

35 7.174 23.83 0.9683 10.42
65 7.616 25.3 0.965 10.49

125 8.179 27.17 0.9443 12.55
  1. *”Dis” instead of “Deg” because substance exchange between the layers is possible
