Levels of Two Earthy and Musty Odor Compounds, 2-Methylisoborneol and Geosmin, in Wastewater and Concentration Variations during Treatment

Journal of Water and Environment Technology, 2023
We determined the concentrations of 2-methylisoborneol (2-MIB) and geosmin in final effluent from wastewater treatment plants in Kyoto City, Japan, investigating variations during treatment.

Cavitands: capture of cycloalkyl derivatives and 2-methylisoborneol (2-MIB) in water

, 2019
Cycloalkyl derivatives such as halides and alcohols are commonly encountered in chemical synthesis and in the environment, yet chemical methods for their sensing are limited. Here we develop a sensor–a deep cavitand–on a preparative scale.

Radiolytic degradation of 2-methylisoborneol and geosmin in water: Reactive radical species and transformation pathways

Chemical Engineering Journal Advances, 2021
Water radiolysis can serve as a useful tool to study the degradation of organic pollutants in water. Manipulation of the radiolytic system enables the selective production of reactive species (RS) with known yields.

Volatile Emissions From Diverse Estuarine Bacteria Share Core Compounds With a Subset of Strain‐Specific, Low Abundance Compounds

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Biogenic volatile organic compounds (BVOCs) emissions from 16 heterotrophic bacterial strains cultivated from Baltic Sea surface waters were quantified using PTR‐ToF‐MS. Strains showed broadly overlapping volatilomes with no clear phylogenetic relationship. Acetone was highly abundant in most strains, along with a suite of core compounds.

DETERMINATION OF GEOSMIN AND 2-METHYLISOBORNEOL IN WATER BY HEADSPACE LIQUID-PHASE MICROEXTRACTION COUPLED WITH GAS CHROMATOGRAPHY-MASS SPECTROMETRY

, 2011
Geosmin (GSM) and 2-methylisoborneol (MIB) were extracted from water samples, adsorbed in organic solvent microdrop by headspace liquid-phase microextraction (HS-LPME), and were analyzed by gas chromatography-mass spectrometry (GC-MS).

Dryland Soil Rewetting Induces Strong Volatile Organic Compound Emissions With Potential to Form Ozone and Aerosols

Global Change Biology, Volume 32, Issue 10, October 2026.
Rainfall after drought triggers strong petrichor VOC emissions from dryland soils. These emissions are chemically diverse, shaped by aridity and soil microbial community, and can increase regional ozone and secondary organic aerosol formation potentials.

Geosmin and 2-methylisoborneol removal in drinking water treatment

Water Practice and Technology, 2022
Abstract Geosmin (GSM) and 2-methylisoborneol (2-MIB) are metabolites derived from cyanobacteria which produce taste and odor problems in drinking water treatment plants. Conventional treatment processes in water treatment are ineffective for the removal of 2-MIB/GSM.

Development and validation of a challenge model using geosmin‐spiked feeds to obtain off‐flavor compounds in tissues of Atlantic salmon, Salmo salar

Journal of the World Aquaculture Society, Volume 57, Issue 5, October 2026.
Abstract Fish produced within recirculating aquaculture systems may develop flavors not desired by end‐consumers, hereafter “off‐flavor,” which is largely attributed to geosmin accumulation in fish tissues. To develop methods for mitigating geosmin accumulation, a reliable and reproducible method of introducing geosmin in fish tissue is needed. Current

Production and release of 2-MIB in Pseudanabaena: Effects of growth phases on cell characteristics and 2-MIB yield

Ecotoxicology and Environmental Safety
2-methylisoborneol (2-MIB), a secondary metabolite produced by cyanobacteria, often causes a musty odour in water, threatening the safety of drinking water supplies.
