Measuring the effect of increasing salinty on the concentration of Dissolved oxygen

I want to investigate the effect of increasing salinity on the concentration of dissolved oxygen, in a water sample being distilled water.
Would that work?


My concern is, that since its not a true fresh water sample, I am worried that changing the salinity of distilled water, to create different saline solutions, would impact the oxygen content significantly?


I want to model the direct relationship, so I can apply it to a real life example. For instance the effect of road salting on oxygen concentration in fresh water habitats.
