LC-MS/MS methods for the determination of 30 quaternary ammonium compounds including benzalkonium and paraquat in human serum and urine

Journal of Chromatography B: Analytical Technologies in the Biomedical and Life Sciences, 2023
Benzalkyldimethylammonium (or benzalkonium; BACs), alkyltrimethylammonium (ATMACs), and dialkyldimethylammonium compounds (DDACs) have been widely used for over six decades as disinfectants, especially during the COVID-19 pandemic. Here we describe methods for the determination of 7 BACs, 6 ATMACs, 6 DDACs, 8 BAC metabolites, and the structurally ...

Mass loading, removal and emission of 27 quaternary ammonium compounds, including metabolites of benzalkonium, in a wastewater treatment plant in New York state, USA

Journal of Hazardous Materials
Benzylalkyldimethylammonium (BACs), dialkyldimethylammonium (DDACs), and alkyltrimethylammonium compounds (ATMACs) are quaternary ammonium compounds (QACs) widely used in industrial and consumer products. Nevertheless, little is known about their fates in wastewater treatment plants (WWTPs).

[Simultaneous determination of chlorhexidine acetate and benzalkonium chloride in compound chemical disinfectants by capillary electrophoresis].

Se pu = Chinese journal of chromatography, 2013
Benzalkonium chloride (BAC) is a mixture of alkyl substituted benzyl dimethylammonium chloride homologs (C12-BAC, C14-BAC and C16-BAC). Chlorhexidine acetate is a widely used effective component in compound chemical disinfectants. A method for the simultaneous determination of chlorhexidine acetate and benzalkonium chloride in compound chemical ...

Benzalkonium chloride: selective inhibitor of histamine release induced by compound 48/80 and other polyamines.

The Journal of Pharmacology and Experimental Therapeutics, 1979
Benzalkonium chloride (BAC) is a mixture of quaternary benzyldimethylalkylammonium chlorides which was found to inhibit histamine release induced by polyamines (48/80, ATP, bradykinin, curare, guanethidine, polylysine, polymyxin B, poly-THIQ, protamine, stilbamidine or substance P), but not that caused by antigens, concanavalin A, dextran, lonophores ...

Toxicity and genotoxicity of the quaternary ammonium compound benzalkonium chloride (BAC) using Daphnia magna and Ceriodaphnia dubia as model systems

Environmental Pollution, 2016
The toxicity and genotoxicity of the cationic surfactant benzalkonium chloride (BAC) were studied using Daphnia magna and Ceriodaphnia dubia as model systems. Acute and chronic toxicity testing were performed according to the international standard guidelines and the genotoxicity was detected through the comet assay on cells from whole organisms in ...

A zoospore inhibition technique to evaluate the activity of antifungal compounds against Batrachochytrium dendrobatidis and unsuccessful treatment of experimentally infected green tree frogs (Litoria caerulea) by fluconazole and benzalkonium chloride

Research in Veterinary Science, 2009
Effective and safe treatments of chytridiomycosis in amphibians, caused by Batrachochytrium dendrobatidis, are needed to help prevent mortality in captive programs for threatened species, to reduce the risk of spread, and to better manage the disease in threatened populations.

[Toxic contact dermatitis due to the quaternary ammonium compound benzalkonium chloride (author's transl)].

Dermatosen in Beruf und Umwelt. Occupation and environment, 1980
A 20-year-old soldier caught an eczematous contact dermatitis on the left ear after the protection of hearing "Selektone" had been adapted. The protection of hearing had been disinfected before in a Zephirol solution 1% aqueous. Zephirol contains the quaternary ammonium compound Benzalkonium chloride.
