Trihalomethanes (THMs) are regulated disinfection by-products (DBPs), analyzed in drinking water due to their toxicological health effects. However, few data exist regarding the content of emerging THMs in drinking water, which are present at very low concentrations. This study aimed to monitor hazardous and emerging THMs from drinking water supply in a residential area via solid phase microextraction using gas chromatography. Response surface methodology was employed to evaluate the role of… 
Comparison of chlorination and chloramination practices on microbial inactivation efficiencies within a scaled‐up water distribution network using central composite design
Disinfection practices reduce the incidence of water‐borne diseases but may result in formation of disinfection byproducts (DBPs) in raw water that are reported to be carcinogenic. Central composite
Evaluation of genotoxicity and hematological effects in common carp (Cyprinus carpio) induced by disinfection by-products.
Results demonstrated that iodoform was statistically more damaging as compared to chloroform, suggesting liver damage in fish specimens exposed to spiked DBPs.


Fuzzy risk-based decision-making approach for selection of drinking water disinfectants
A framework for comparative evaluation of disinfectants and their application approaches has been developed through incorporation of human health risk from DBP exposure, cost of disinfection process, technical feasibility and disinfection performance through a multi-stage hierarchy risk model.
Halonitromethane drinking water disinfection byproducts: chemical characterization and mammalian cell cytotoxicity and genotoxicity.
This research demonstrated the integration of the procedures for the analytical chemistry and analytical biology when working with limited amounts of sample and found the brominated nitromethanes were more cytotoxic and genotoxic than their chlorinated analogues.
Solventless Microextraction Techniques for Determination of Trihalomethanes by Gas Chromatography in Drinking Water
Three different solventless sample preparation techniques based on microextraction, membrane extraction, and headspace extraction have been developed and optimized for determination of
Simultaneous analysis of 23 priority volatile compounds in water by solid-phase microextraction–gas chromatography–mass spectrometry and estimation of the method's uncertainty
Most water contaminations with volatile organic compounds (VOCs) are traceable to leaking underground fuel reservoirs, solvent storage vessels, agricultural practices, industrial residues, and
