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.

Freshwater stormwater ponds are the most susceptible to fish kills. They collect both water runoff and the contaminants that ...

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 ...

Without intervention, the trend could continue to undermine the stability of freshwater ecosystems that billions of people ...

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 ...

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, ...

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

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 ...

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 ...

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

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 ...
