Ammonia or ammonium? What’s the difference? In water, ammonia (NH3) and ammonium (NH4+) exist together in an equilibrium that depends on pH and temperature. As the temperature or pH rise, ammonia (NH3) becomes more abundant. This is important because ammonia is more toxic than ammonium.

The Animated Nitrogen Cycle
This animation of the biogeochemical nitrogen cycle illustrates the main steps of the cycle in air, water, and soils. The video explains and connects the many forms of nitrogen, such as ammonia, ammonium, hydroxylamine, nitrite, nitrate, nitrous oxide, and nitrogen dioxide, and explains the role of nitrate in nitric oxide signaling in the human body.

USGS Missouri River Dye Tracing Assessment
Scientists from the U.S. Geological Survey conducted a dye-trace assessment on May 5, 2021 along the Missouri River near Huntsdale, Missouri. The assessment helped scientists understand how larvae from the critically endangered pallid sturgeon drift downstream after hatching and how they find supportive habitat in the complex Missouri River.
