Caractérisation des sous-produits de chloration de la microcystine-LR et de la cylindrospermopsine

Abstract : With climate change and anthropic pressure, the occurrence of cyanobacteria blooms and the related toxins in surface water used to produce drinking water is a growing public health concern since various intoxications have been reported worldwide. In order to protect consumers' health, cyanotoxins behaviour towards classical processes like disinfection by chlorine should be examined. The present study investigated chlorination of a common cyanotoxin and an emerging one: microcystin-LR and cylindrospermopsin. The reaction between chlorine and toxins was characterized and various by-products were identified through ultraviolet spectrophotometry and high resolution mass spectrometry. Then tests performed on bacteria Vibrio fischeri and on Caco-2 cells allowed to assess the effect of chlorination on mixture toxicity.
