Overview
Dissolved oxygen (DO) is the amount of gaseous oxygen present in water, and it is one of the most important indicators of the health of aquatic ecosystems. Oxygen enters water through diffusion from the atmosphere and through photosynthesis by aquatic plants and algae, while it is consumed by respiration, decomposition, and chemical oxidation. Adequate dissolved oxygen is essential for fish, invertebrates, and the microorganisms that drive nutrient cycling, so its concentration directly affects biodiversity and water quality. Levels are influenced by temperature, salinity, organic loading, photosynthesis, and pollution; warmer or more polluted waters generally hold less oxygen, and high inputs of organic matter raise biochemical and chemical oxygen demand, which can deplete DO and stress aquatic life. For these reasons, dissolved oxygen is a routine parameter in monitoring rivers, lakes, wetlands, and wastewater treatment systems. Research relevant to this topic examines how agricultural land use, industrial activity, and effluent discharge affect water quality, how biochemical and chemical oxygen demand relate to one another in treatment settings, and how aquatic organisms respond to changing oxygen conditions. This page brings together peer-reviewed, open-access research relevant to dissolved oxygen, water quality, and oxidative processes in aquatic environments.
