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

Chemosensors, 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 ...

Cometabolism of Trihalomethanes by Nitrosomonas europaea [PDF]

Applied and Environmental Microbiology, 2005
ABSTRACT The ammonia-oxidizing bacterium Nitrosomonas europaea (ATCC 19718) was shown to degrade low concentrations (50 to 800 μg/liter) of the four trihalomethanes (trichloromethane [TCM], or chloroform; bromodichloromethane [BDCM]; dibromochloromethane [DBCM]; and tribromomethane [TBM], or bromoform ...

A case of canine urothelial carcinoma of the urinary bladder with skull and skeletal metastases

Australian Veterinary Journal, Volume 104, Issue 8, Page 509-514, August 2026.
Canine urinary bladder neoplasia is uncommon, representing less than 1% of canine neoplasms. Amongst cases of urinary bladder neoplasia in dogs, primary urothelial carcinoma is the most frequent. Urothelial carcinomas are malignant invasive tumours which tend to be slow growing and metastasise late.

Removal of natural organic matter from water by coagulation and flocculation to mitigate the formation of chlorine-disinfection by-products: a case study at Chinaimo water treatment plant, Vientiane capital, Laos

Vietnam Journal of Science, Technology and Engineering, 2022
The reaction between natural organic matter (NOM) and chlorine during disinfection of water potentially forms trihalomethanes (THMs), which are classified as dangerous, carcinogenic disinfection by-products.
