Travail en cours My current work involves: (I) elucidating the formation mechanisms of carcinogenic/mutagenic N-nitrosamines in aquatic systems under varying environmental conditions, (II) developing new analytical tools to detect and quantify N-nitroso compounds in water and biological fluids, and (III) elucidating the role of disinfection agents in the prevalence of antibiotic resistant bacteria in wastewater RechercheConferences Breider F., von Gunten U., (2017) Novel method for the quantification of the total N-nitrosamines concentration (TONO) in water, American Chemical Society Meeting, San Francisco, USA Yoshikawa C., Sasai Y., Makabe A., Breider F., Toyoda S., Matsui Y., Kawagucci S., Wakita M., Fujiki T., Harada N., Yoshida N., (2017) Development of a model of nitrous oxide in the western North Pacific, Japan Geoscience Union-American Geoscience Union Joint Meeting, Chiba, Japan Toyoda S., Kudo K., Breider F., Yamada K., Yoshida N., Sasano D., Kosugi N., Ishii M., Yoshikawa-Inoue H., Nishino S., Uchida H., Murata A., (2014) Distributions of methane, nitrous oxide and their isotopomers in the Arctic Ocean, 5th Symposium on Polar Science, Tokyo, Japan Breider F.

Dialogues urbains: durabilité et médiation PENS-233 Ce cours, en partenariat avec la HEP Vaud, traite de la ville durable et des potentiels de la médiation culturelle et scientifique. Les enjeux environnementaux et sociaux sont abordés en lien avec la rivière de la Chamberonne, pour concevoir et animer un atelier de médiation pour des classes.
