A 38-year analysis of 21,000 waterways found rivers losing oxygen worldwide, with tropical systems declining fastest due to ...

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 ...

Rivers around the world are quietly running out of oxygen — and climate change is emerging as the main culprit. A sweeping ...

A new report card assessment says the Boise River is mostly healthy, with top marks for clarity, average water temperatures, pH levels, and trash removal.

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 ...

After all the work you’ve done with lighting, extractor fans, nutrients, grow medium, watering and everything else you need to consider when growing good cannabis indoors, an invisible component of ...

Hundreds of dead fish turned the shoreline of the pond at University Park, locally known as Crystal Park, into a grim scene ...

The absorption of light by organic molecules with chromophores contribute to the formation of brown carbon in the atmosphere, which can partially counteract the expected cooling effect of aerosols on ...

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 ...
