Reference number : GC-2017-Q2-00101, amendment number : , agreement type : G, recipient legal name : Bayen, Stephane (McGill University)|Bayen, Stephane (Université McGill), recipient country : CA, recipient province : nan, recipient city : Quebec|Québec, recipient postal code : nan, program name english : Engage Grants for Universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : The company partner in this Engage Grant, RHST Industries, has developed a novel technology described as_x000D_
polymer beads under the trade name of Water Pearls aimed at increasing the efficient use of energy and_x000D_
lowering the environmental footprints in order to obtain sustainable food production (soil agricultural and_x000D_
hydroponic applications). The success of the novel material is related to sustainability. The possible leaching of_x000D_
chemicals from polymer materials (e.g. unreacted polymer and plasticizers) is a concern, as they could be_x000D_
harmful to the plants or accumulate in it. To date though, no standards have been clearly defined to assess_x000D_
chemical migration for materials used for hydroponics. In the absence of such a standard, RHST Industries_x000D_
decided to take a proactive step with researchers to assess chemical leaching from its innovative product. This_x000D_
Engage Grant application seeks to establish a collaboration between RHST Industries and the applicant, Dr_x000D_
Bayen at McGill University. The objectives are: (i) the development of a migration test to simulate chemical_x000D_
migration under hydroponics conditions and identify the leaching organic migrants using HPLC-HRMS, (ii) the_x000D_
quantification of the mass transfer for target chemicals under different controlled conditions, and (iii) the_x000D_
review the available information in the literature on the toxicity of the major organic migrants on mammals and_x000D_
plants. Dr Bayen's laboratory is equipped with high resolution mass spectrometry (HPLC-QTOF-MS/MS), the_x000D_
state-of-the-art technology for the identification of such "unknown" chemicals and the investigation of the_x000D_
stability of polymer material. Successful completion of the project described in this application will lay the_x000D_
foundation for further collaboration between the applicant and RHST Industries on analytical methodology_x000D_
