These are coupled to a less and a more persistent compound in water,
respectively FOCUS Compound A_sw and H_sw.

For substance A_sw the results of
v1.1.1 and v2.2.1 are exactly the same.
For substance H_sw the PECs
calculated with v1.1.1 and v2.2.1 differ slightly for most runs. The largest differences in global max if found for the D1-Ditch
scenario, which is 0.206 mg/L lower than the corresponding global max of FOCUS_TOXSWA v1.1.1. The
largest difference in TWAC 28 d is found for the D2-Ditch scenario, which is 0.253
mg/L higher than the corresponding
TWAC 28 d of FOCUS_TOXSWA v1.1.1. The differences in calculated PECs are due to
the tighter selection of the calculation time steps in the water layer for
substances with Koc values between 10 and 100 L/kg (Koc of H_sw is 100 L/kg)
(See the ‘Differences between TOXSWA_2.2.1 and TOXSWA_1.1.1’ document, item m1).
The differences in PECs between v1.1.1 and v2.2.1 are smaller than 0.2%, so
considered not significant.
[1] Please note that these runs are
intended as a test for the TOXSWA software only. They do not correspond to
sensible, consistent step 3 FOCUS runs that can be used for risk assessment
purposes. (E.g. because PRZM and MACRO do calculations for a pesticide with
D-sw properties, while TOXSWA performs calculations for a pesticide with A-sw
or H-sw properties.)
