Thermal degradation of haloacetic acids in water

, 2010
Haloacetic acids are commonly found in most natural waters. These are known as degradation products of some halogenated compounds such as C2- chlorocarbons and CFC replacement compounds: hydroflurocarbons (HFCs) and hydrochloroflurocarbons (HCFCs). While

Occurrence of disinfection by-products in the Krakow water supply system with respect to compliance EU standards

Desalination and Water Treatment
The research explored the presence of disinfection by-products (DBPs) in drinking water supplied to the Krakow agglomeration and compared it with the guidelines in Directive (EU) 2020/2184. The paper looked particularly into DBPs: haloacetic acids (HAA),

Degradation of 4-nonylphenol in bromide-containing water by UVC/O3/TiO2-combination processes: Impacts on trihalomethanes and haloacetic acids formation

Emerging Contaminants
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).

Moisture and Species Effect on Water Colour Generation in an Australian Temperate Forested Catchment

Ecohydrology, Volume 18, Issue 6, September 2025.
ABSTRACT South‐eastern Australian forested catchments supply most of Melbourne's drinking water, and discoloured water poses significant challenges for authorities because of the need for complex and costly treatment procedures. Identifying the sources and mechanisms of colour production is therefore critical.

Guidance on the use of read‐across for chemical safety assessment in food and feed

EFSA Journal, Volume 23, Issue 7, July 2025.
Abstract Read‐across is a method used in chemical risk assessment to predict the toxicological properties of a target substance by using data from structurally and mechanistically similar substances, known as source substances. EFSA's Scientific Committee has developed an approach for using read‐across in food and feed risk assessment.
