Abstract The presence of natural organic matter (NOM) and anthropogenic (AOM) in polluted river water leads to the formation carcinogenic disinfection by-products (DBPs) during chlorination process. This study aimed determine trihalomethanes (THMs) formation, as regulated DBPs, tropical water. samples were taken from Citarum River, Bandung, Indonesia. NOM AOM characterized using UV 254 , 355 ul...

This study analysed the spatial and temporal occurrence of 29 disinfection by-products (DBPs) formed by chlorination chloramination.

Five malonanilide derivatives (M1-M5) were prepared by the reaction of ethyl malonate with aniline derivatives. These compounds were investigated as new stabilizers for double-base propellants (DBPs). The evaluation process has been performed through thermal stability tests, thermal analyses measurements (TGA and DSC) and kinetic parameters calculations (E(a)). The results of the new stabilizer...

The use of chlorination to purify water supplies is considered one of the most important public health advances of the twentieth century. Following the 1908 introduction of widespread water chlorination, once-common diseases such as cholera, dysentery, and typhoid fever were practically eliminated. However, the chlorination cure-all proved to have a caveat: disinfection by-products (DBPs), whic...

Digital battery passports (DBPs) may help support the transition towards more sustainable and circular electric vehicle (EVB) value chains by providing respective chain actors with valuable data in management. To ensure such support, DBPs have to fulfil EVB actors' needs requirements. This work sets out provide initial empirical insight into requirements context of The analysis is based on a DB...

The aim of this in vitro study was to compare the long-term effect overnight use denture cleansers with different chemical compositions on color stability base polymers (DBPs). four DBPs evaluated were PEEK (PK group), thermoinjection-molded polyamide (PA auto-polymerized polymethylmethacrylate (PMMA) (AP and heat-polymerized resin PMMA (HP group). cleaning agents used Corega tablet (CT), Prote...

a headspace-solid phase microextraction (hs-spme) and gas chromatography-mass spectrometry (gc-ms) method has been developed for the simultaneously determination of 20 disinfection by-products (dbps) in water samples from reverse osmosis (ro) membranes. selected compounds belong to different families including: trihalomethanes (thms), halogenated acetonitriles (hans), halogenated nitromethanes ...

Disinfection of drinking water is regarded as one of the major public health achievements of the twentieth century, resulting in drastic reductions in diseases such as cholera and typhoid fever. However, potentially hazardous disinfection by-products (DBPs) can form when water treatment chemicals interact with other compounds in the water. In this issue of EHP, investigators assess the reproduc...

Nano-silver is increasingly used in consumer products from washing machines and refrigerators to devices marketed for the disinfection of drinking water or recreational water. The nano-silver in these products may be released, ending up in surface water bodies which may be used as drinking water sources. Little information is available about the stability of the nano-silver in sources of drinki...
