Carbon dioxide is made up of one carbon atom covalently bonded to two oxygen atoms. Although electrons are shared, they are not shared equally between the carbon and the oxygen atoms. The oxygen atom ...

Dissolved oxygen is a measure of the amount of gaseous oxygen (as O 2) dissolved in water. Oxygen enters the river water from the atmosphere (via diffusion), from groundwater, and also as a by-product ...

Climate change is revealing oxygen levels in lakes are decreasing faster than experts expected due to warmer temperatures.

The sucrose molecules dissolve as they are separated from the other molecules and mix into the water. The sucrose molecule has many oxygen-hydrogen (O–H) bonds which are polar. The charge-density ...

Scientists know that streams and rivers can contribute significant quantities of greenhouse gases to the atmosphere. One way ...

The US Army Corps of Engineers Nashville District is installating an oxygen diffusion system at Wolf Creek Dam ...

This innovative system will allow the dam’s hydropower plant to operate more efficiently during times of year when dissolved oxygen (DO) levels in the water drop below environmental targets.

An effort to improve the water quality of a stretch of the Delaware River that has been chronically polluted took a step ...

Parts of the Delaware River have low dissolved oxygen levels caused by ammonia discharges from wastewater facilities.

Insight into the characterization of dissolved organic matter in shallow lakes with different trophic states and their net photo-generation capacity of reactive oxygen species, Water Research (2025).
