An automated micro solid phase extraction gas chromatography–mass spectrometry (μSPE-GC–MS) detection method for geosmin and 2-methylisoborneol in drinking water

open access: yesScientific Reports, 2023
Geosmin and 2-methylisoborneol (2-MIB) are amongst the most common earthy and musty taste and odour (T&O) compounds found in drinking water. With low odour threshold detection limits below 10 ng L−1, and the complexity of raw water matrices, these two ...

Impact of water quality parameters on geosmin levels and geosmin producers in European recirculating aquaculture systems

open access: yesJournal of Applied Microbiology, 2021
Geosmin is associated with off‐flavour problems in recirculating aquaculture systems (RAS) and represents an economic problem for the aquaculture industry.

HS-SPME-GC/MS Method for the Simultaneous Determination of Trihalomethanes, Geosmin, and 2-Methylisoborneol in Water Samples

open access: yesChemosensors, 2023
Drinking water treatment plants (DWTP) use chlorination as an oxidation stage in the first step of the processes used to eliminate the natural organic matter (NOM) responsible for the formation of 2-methylisoborneol (2-MIB) and Geosmin (GM), which ...

Modeling geosmin removal in a full-scale filter [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2020
Taste and odor compounds affect drinking water safety perception and may drive consumers to less secure water sources. Adsorption, using powered activated carbon, is the most common method to remove these compounds but greatly increases the amount of ...

The analytic hierarchy process method to design applicable decision making for the effective removal of 2-MIB and geosmin in water sources. [PDF]

open access: yesEnviron Sci Pollut Res Int
Numerous utilities encounter issues with taste and odor that alter the public’s impression of the safety of drinking water. The creation of certain components in water naturally due to global climate change is another source of taste and odor components,

Type-specific molecular signaling architectures and synaptic plasticity of Drosophila olfactory sensory neurons [PDF]

open access: yesFrontiers in Cellular Neuroscience
Olfactory sensory neurons (OSNs) detect odours at a wide range of intensities. In Drosophila, volatile compounds bind to specific odorant receptors (ORs), which tune the sensitivity of chemoreception.

Effects of Geosmin on the Behavior of Soil Protists. [PDF]

open access: yesMicrob Ecol
Geosmin is a volatile organic compound (VOC) produced by a range of different soil microorganisms, and is most commonly recognized for its characteristic "earthy" scent evident after rainfall. Though it remains unclear why microorganisms produce geosmin, we know that exposure to geosmin can influence behaviors across a wide range of organisms, serving ...

Seasonal Rise in the Contents of Microcystin-LR and Odorous Substances Due to Cyanobacterial Blooms in a Drinking Water Reservoir Supplying Xinyang City, China [PDF]

open access: yesToxins
Cyanobacterial blooms have become a serious water pollution problem in many parts of the world, and the monitoring and study of the impacts of biotoxins on human health are of vital importance.

Influence of Temperature Regimes on the Production of 2-MIB and Geosmin by Pseudanabaena galeata and Phormidium ambiguum. [PDF]

open access: yesWater Environ Res
Two cyanobacteria species Pseudanabaena galeata and Phormidium ambiguum were exposed to 20°C, 30°C, and 40°C for a 10‐day period, and samples were taken every other day for a 10‐day period. Both species showed significant changes in odor compound production at different temperature regimes.

Geosmin reduction by algaecide application to drinking water: field scale efficacy and mechanistic insights

open access: yesHeliyon, 2021
Ten years of field data from an Oklahoma drinking water utility were analyzed for the effects of an acid-stabilized, ionic copper algaecide/bactericide called EarthTec on geosmin concentrations in the water traveling by pipeline from the source lake to a
