The amount of dissolved oxygen in a river is a matter of life or death for the plants and animals living within it, but this oxygen concentration varies drastically from one river to another, ...

Dissolved oxygen analyses are performed with an SIO/ODF-designed automated oxygen titrator using photometric end-point detection based on the absorption of 365nm wavelength ultra-violet light. The ...

Dissolved oxygen meters are used to quantify the amount of dissolved oxygen (DO) in surface waters or at different stages of wastewater treatment. There are two dissolved oxygen meters in the ...

Fish and other aquatic organisms survive in water because of DO. The amount of DO in water is affected by the water temperature, salt concentration, and atmospheric pressure, among other factors.

What is dissolved oxygen (DO)? Why is this parameter so relevant, e.g., for water analysis, and which technologies are used to determine it? In a free White Paper, Dr. Sabrina Gschwind, product ...

Published on Friday in the journal Nature Geoscience, the research found that oxygen levels in China's inland waters actually increased between 2005 and 2022, despite surface waters warming at a rate ...

Over the past 17 years, China's rivers and lakes have experienced a surprising increase in dissolved oxygen levels despite ...

Chinese scientists have recently developed a novel method for measuring dissolved oxygen (DO) levels in the ocean and a new dataset for monitoring dissolved oxygen concentration (DOC) of global oceans ...

Reactive oxygen species (ROS) are critical drivers of aquatic biogeochemical processes, with dissolved organic matter (DOM) serving as a primary photosensitive source of ROS in natural waters. Despite ...

Oxygen concentrations rose as much as 12% over a decade, a rare environmental success story as climate change warms water.
