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.

Predictive Modeling of Bacterial Inactivation With Hydrogen Peroxide Over a Cobalt Ferrite Catalyst

ChemPhysChem, Volume 27, Issue 14, 29 July 2026.
Hydrogen peroxide decomposition over a cobalt ferrite catalyst generates hydroxyl radicals for bacterial inactivation. A hybrid machine learning model combining gradient boosting and random forest accurately predicts nonlinear disinfection kinetics, offering a new data‐driven framework for catalytic advanced oxidation processes and intelligent water ...

Effectiveness of biosurfactant for the removal of trihalomethanes by biotrickling filter

Engineering Reports, 2019
In this study, the biodegradation of a mixture of two trihalomethane (THM) compounds, chloroform (CF) and dichlorobromomethane (DCBM), was evaluated using two laboratory‐scale biotrickling filters (BTFs).

Potential cancer risk estimates from trihalomethanes in peri-urban settings of Kawama East of Mufulira, Zambia

Journal of Water and Health, 2022
In this study, we report the formation and cancer risk estimation of trihalomethanes (THMs) emanating from ‘ex-situ’ chlorination of shallow hand-dug well water obtained from a peri-urban area of Mufulira District, Zambia.

Identification of Sources of Dissolved Organic Matter Using Multi‐Isotope Approach

CLEAN – Soil, Air, Water, Volume 54, Issue 7, July 2026.
• A precise and multi‐isotope method was developed using solid phase extraction (SPE) and Element Analyzer – Isotope Ratio Mass Spectrometry (EA‐IRMS) to characterize the dissolved organic matter (DOM). • The DOM extraction and elution methods were standardized for natural waters containing as low as 0.5 mg DOM. • The extraction efficiencies range from

Bromoform exposure is associated with non-melanoma skin cancer: evidence from NHANES 2011–2020

Frontiers in Public Health, 2023
BackgroundNon-melanoma skin cancer (NMSC) is a prevalent skin malignancy. It has been indicated in many studies that trihalomethanes (THMs) exposure has a strong association with tumors but has not been associated with NMSC.
