SESSION: CURRENT STATUS OF ENVIRONMENTAL RESEARCH ON WATER CONTAMINANTS:  

Iopromide (IPM), a type of iodinated contrast media, is frequently detected in wastewater treatment plants, sometimes up to 10 µg/L at wastewater treatment plants…

Bisphenol A (BPA) is an endocrine-disrupting compound (EDC) that is mainly released from anthropogenic sources. In this study, the degradation mechanism of BPA during vacuum ultraviolet (VUV) reaction was investigated…

Oseltamivir is widely used as an antiviral drug and it has been a concern in the aquatic environment. In this study, the degradation mechanisms of oseltamivir were investigated in UV photolysis and UV/H2O2 reactions…

This study examined the abundance of microplastics (MPs) in 106 fish from 22 families inhabiting the Han River (South Korea). In total, 1,753 MPs in 106 fish samples were identified with an average number of MPs of 15.60 ± 13.45 MPs per individual fish (MPs indiv-1) in the North Han River, 16…

Semiconductor wastewater usually has low dissolved oxygen levels because ultra-pure water and solvents underwent a rigorous degassing process…

Hexafluoropropylene oxide dimer acid (HFPO-DA), commonly referred to as GenX, is a replacement compound for the straight-chain perfluoroalkyl substance (PFAS), perfluorooctanoic acid (PFOA)…

Perfluorooctanoic acid (C7F15COOH, PFOA) has attracted attention due to its chemical durability, wide distribution, biotoxicity, and bio-accumulative properties…

During drinking water treatment, chlorination leads to the degradation of bisphenol A (BPA) and the formation of chlorinated derivatives (ClxBPA) which have higher estrogenic activity than BPA…

Perfluorooctanoic acid (C7F15COOH, PFOA) has attracted attention due to its chemical durability, wide distribution, biotoxicity, and bio-accumulative properties. The UV radiation under 200 nm is known as vacuum UV (VUV), an alternative technology to treat micropollutants…

Consumer products containing numerous chemical substances increase the risk of human exposure as their usage increases. However, there are a lack of research on the identification of chemicals in consumer products…

Per and polyfluoroalkyl substances (PFAS) are contaminants of concern because they persist in the environment and water treatment systems…

Hexafluoropropylene oxide dimer acid (known as GenX) is known to have adverse effects on human health, thus the treatment for removing GenX in water is necessary…

This study investigated the removals of 53 micropollutants (MPs), including 10 per- and polyfluoroalkyl substances (PFAS), 25 pharmaceuticals and personal care products (PPCPs), 7 pesticides, 3 endocrine disrupters (EDCs), 3 disinfection byproducts (DBPs) and 3 taste and odor compounds (TNOs), duri…

The use of volatile organic compounds (VOCs) used in consumer products is a source of chemical exposure that is potentially harmful to humans…

Benzopenone-8 (BP-8) is an ultraviolet (UV) filter commonly used in sunscreen and plastic products. BP8 can cause acute and chronic toxicity in living organisms because it is biologically toxic and bioaccumulates…

Wastewater treatment plants (WWTPs) serve as notable origins of per- and polyfluoroalkyl substances (PFASs)…

This study aimed to identify PFAS present in consumer products and to understand the relationship between these substances and their precursors…
