Mutation spectra of the drinking water mutagen 3-chloro-4-methyl-5-hydroxy-2(5H)-furanone (MCF) in Salmonella TA100 and TA104: Comparison to MX

Carcinogenicity of the drinking water mutagen 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone in the rat.

BACKGROUND Several epidemiologic studies have suggested that the consumption of chlorinated drinking water may be associated with the development of certain cancers in humans. 3-Chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX), a byproduct of the chemical reactions that occur in chlorinated drinking water, has been found to be mutagenic in bacteria and mammalian cells; however, its poten...

3-Chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX) and mutagenic activity in Massachusetts drinking water.

There is limited information on the prevalence of the potent mutagen 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX) in U.S. water supplies. We measured MX concentrations and mutagenic activity in tap water samples from 36 surface water systems throughout Massachusetts. We found MX levels much higher (up to 80 ng/L) than previously reported in the United States. We also evaluated the ...

DRAFT: Evidence on the carcinogenicity of MX (3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone

Solid-Phase Microextraction for Determination of 3-Chloro-4-(dichloromethyl)- 5-hydroxy-2[5H]-furanone in Water

Microextração em fase sólida, usando a derivatização on-line com bis(trimetilsilil)trifluoroacetamida, cromatografia a gás e espectrometria de massas, foi avaliada para a quantificação de 3-cloro-4-(diclorometil)-5-hidróxi-2(5H)-furanona (MX) em amostras de água. Foram usadas fibras de diferentes polaridades empregando a amostragem por imersão e por headspace. Para o sistema de imersão, foram a...

3-Chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX) induces gene mutations and inhibits metabolic cooperation in cultured Chinese hamster cells.

Investigations were carried out on 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX), a potent direct-acting bacterial mutagen found in chlorinated tap water, for the potential to induce 6-thioguanine (6-TG) resistant mutations in cultured Chinese hamster V79 cells. The mutagenicity of MX was manifested when cells were treated with MX in Hanks balanced salt solution, but not in serum-fr...
