Development of rapid and accurate genomic techniques for ballast water UV treatment

The United States Coast Guard (USCG) recently introduced stringent regulations for the treatment of ballast water. Ultra-violet (UV) light is a useful technology in a ballast water treatment system (BWTS), for inactivating phytoplankton which could be invasive and harmful to humans and the environment. UV damages DNA and prevents replication, but the vital stain methods mandated in the USCG protocol do not detect UV damage. Alternative culture-based measures of reproductive capacity are yet to be approved, time consuming, and have limitations (not all species may grow).

Action spectra characteristic of typical and potentially new challenge organisms used in polychromatic UV reactor validation Year One

Trojan Technologies provides UV-based technologies for water, wastewater and reuse wastewater treatment. This proposal is directed towards optimizing and developing the validation protocols for UV systems provided by Trojan. The study results will expand Trojan's ability to provide more holistic and sustainable reactors for water/wastewater treatment as well as expand the polychromatic UV market.

Études des effets de la désinfection aux UV sur l’activité œstrogène dans les eaux usées

Ce projet est en collaboration avec le Réseau canadien de l’eau. On désigne généralement « perturbateurs endocriniens » les substances chimiques ayant des effets sur le système endocrinien des animaux. Des études scientifiques décrivant les impacts des perturbateurs endocriniens sur la faune aquatique du Canada, en particulier les poissons des Grands Lacs, ont sonné l’alarme sur la présence de ces substances dans les milieux aquatiques.
