The test was performed in lake water and sediment at two different dimoxystrobin concentrations (10 μg/L and 90 μg/L).

^(a)

Measured in calcium chloride solution.

^(b)

Temperature of incubation = temperature that the environmental media were collected or std. temperature of 20°C.

^(c)

Normalised using a Q10 of 2.58 to the temperature of the environmental media at the point of sampling. (note temp of × should be stated).
