Another possible cause of low blood oxygen saturation is anemia, which occurs when the red blood cells don't have adequate hemoglobin, an iron-rich protein that acts as the oxygen carrier, according to the National Anemia Action Council. Anemia has many causes.
Dissolved oxygen levels below 3 ppm are stressful to most aquatic organisms. Levels below 2 ppm will not support fish at all. Low dissolved oxygen levels can be the result of elevated temperature and thus the inability of the water to hold the available oxygen.Low dissolved oxygen levels can also indicate an excessive demand on the oxygen in the system.Some pollutants such as acid mine drainage produce direct chemical demands on oxygen in the water for certain oxidation-reduction reactions.ow dissolved oxygen levels can also indicate an excessive demand on the oxygen in the system.
