Levels of Two Earthy and Musty Odor Compounds, 2-Methylisoborneol and Geosmin, in Wastewater and Concentration Variations during Treatment
نویسندگان
چکیده
We determined the concentrations of 2-methylisoborneol (2-MIB) and geosmin in final effluent from wastewater treatment plants Kyoto City, Japan, investigating variations during treatment. The 2-MIB were 5.1–29.8 3.9–13.9 ng/L, respectively. Geosmin primary higher than those influent. concentration increased reactors, while that decreased. anaerobic-anoxic-oxic step-feed biological nitrogen removal processes lowered more did anaerobic-oxic activated sludge process. Other factors regulating earthy musty odor compounds may include flowing secondary settling tank, changes total efficiency, anaerobic conditions reactors or tanks, deterioration sludge, including by formation a scum layer.

Geosmin and 2-methylisoborneol, molecules with the same odor characteristics, are mainly responsible for the smell of soil and cause odor problems worldwide in drinking water supplies. However, the effect of these odor molecules on human brain function is still unclear. The present investigation aimed to evaluate the effect of inhalation of geosmin and 2-methylisoborneol on human electroencepha...

The objective of this study was to analyze organic off-flavors in water by gas chromatography/mass spectrometry (GC/MS) using Stir Bar Sorptive Extraction (SBSE). Six compounds were quantitatively determined using Selected Ion Monitoring (SIM): 2-methylisoborneol (MIB), geosmin, 2,4,6-trichloroanisole, 2,3,6-trichloroanisole, 2,3,4-trichloroanisole and 2,4,6-tribromoanisole. The Limit of Quanti...
