Data on the level of haloacetic acids in indoor swimming pools of Iran: A case study of Tehran. [PDF]

Data Brief, 2018
Haloacetic acids (HAAs) are the second most prevalent class of DBPs after trihalomethanes (THMs) in water disinfected by chlorine compounds. Within this study, we present new data on occurrence and speciation of HAA levels in 15 indoor swimming pools in ...

Formation and estimated cytotoxicity of trihalomethanes and haloacetic acids during ozonation of nonylphenol in bromide-containing water after chlorination process: Impact of ozonation initial pH. [PDF]

Toxicol Rep
The presence of nonylphenol (NP) in bromide-containing water contributed to the formation of regulated disinfection by-products (DBPs): trihalomethanes-4 (THM4) and haloacetic acids-5 (HAA5).

Risks of Birth Defects Following In Utero Exposures to Unregulated Brominated Haloacetic Acids. [PDF]

Birth Defects Res
ABSTRACT Introduction Haloacetic acids (HAAs) are water disinfection byproducts (DBPs) regulated as a mixture of five species (HAA5) in the United States and Canada. To date, two brominated HAAs (BrHAAs) in HAA5 (monobromoacetic acid [MBAA], dibromoacetic acid [DBAA]) have been associated with birth defects in some epidemiologic studies, but the other ...

Enhanced trace detection of haloacetic acids in water using on-line isotachophoresis-capillary zone electrophoresis coupled with liquid-liquid extraction. [PDF]

Sci Rep
Haloacetic acids (HAAs) are toxic disinfection by-products formed during water chlorination. This study presents an optimized method for the trace determination of five HAAs: monochloro-, dichloro-, trichloro-, mono-, and dibromoacetic acids, using an on-

Pilot Study on Nucleation-Induced Pelleting Coagulation in Treatment of High-Algae Surface Water: Coagulant Dosage and Hydraulic Loading Optimization. [PDF]

Toxics
This study proposes a circulating pelletized fluidized bed (CPFB) with micro-sand loading for treating high-algae surface water. Key operational parameters (coagulant dosage, flow rate) were optimized to simultaneously remove algae, turbidity, and ...

Determination of haloacetic acids in bottled and tap water sources by dispersive liquid-liquid microextraction and GC-MS analysis. [PDF]

ScientificWorldJournal, 2014
Haloacetic acids are toxic organic pollutants that can be formed as by-products of disinfection of water by chlorination. In this study, we developed a fast and efficient method for the determination of six species of these compounds in water using ...

Route-resolved priority risks of disinfection by-products in indoor pools: the underestimated role of buccal/sublingual exposure for the public and competitive swimmers. [PDF]

Front Public Health
Disinfection of swimming pools is essential for preventing waterborne diseases; however, reactions between disinfectants and organic/inorganic precursors lead to the formation of disinfection byproducts (DBPs).

Chlorination of Clothianidin During Disinfection: Kinetics, Pathways, and Toxicity. [PDF]

Toxics
Neonicotinoid pesticides are a typical category of emerging hazardous micropollutants, and chlorine (Cl2) is a widely used disinfectant that readily induces the chlorination of organic micropollutants.
