Toxicity of haloacetic acids to freshwater algae
Haloacetic acids (HAA), such as trichloroacetic acid (TCA), are commonly occurring by-products from disinfection and bleaching processes using sodium hypochlorite. Currently, the lowest no observed effect concentration (NOEC) for TCA is reported to be 8.7microgL(-1), which was derived from a toxicity study conducted in 1981 on Chlorella pyrenoidosa ...

Swimming pool water disinfection by-products profiles and association patterns
The aim of this work was to determine and study the concentration of different groups of disinfection by-products (DBPs): trihalomethanes, haloacetic acids, haloacetonitriles, haloacetones and combined chlorine (as an indicator of chloramine levels), in ...

Haloacetic Acids in the Aquatic Environment
Haloacetic acids (HAAs) are a class of disinfection by-products (DBPs), widely occurring in drinking water, wastewater and swimming pool water with concentrations at sub-μg/L to mid-μg/L levels. HAAs arose public attention due to their cytotoxicity, genotoxicity and carcinogenicity.

The influence of different matrices on the nature and content of haloacetic acids precursors in ozonized water [PDF]
This paper investigates the influence of different matrices (groundwater a realistic natural matrix and commercial humic acid solution a synthetic matrix) on the nature and content of haloacetic acid (HAA) precursors in ozonized water (0.4 to 3.0 mg ...

Haloacetic acids in drinking water and risk for stillbirth [PDF]
Background:Trihalomethanes (THMs) occurring in public drinking water sources have been investigated in several epidemiological studies of fetal death and results support a modest association. Other classes of disinfection by-products found in drinking water have not been investigated.Aims:To investigate the effects of haloacetic acid (HAA) compounds in
