Melamine is an s-triazine with three amino groups and is mainly used to synthesize melamine-formaldehyde (MF) resins which are added to kitchenware, textiles, foamed plastics, electric appliances, and flooring to impart fire resistance. Aside from MF resins, melamine is also used in paints and coatings, flooring, machine wash liquids, leather treatment products and is commonly used as material for baby and children cutlery and plates. It is a high production-volume chemical with an import volume of up to 1000000 tons per year into the EU.
Melamine has been recently suggested as a persistent, mobile and toxic (PMT) substance and has gained increasing public attention worldwide. In order to protect public health and aquatic ecosystems and improve water quality, it is essential to understand the occurrence and fate of melamine and its related triazines (i.e., atrazine, cyromazine, ammeline, etc.) in waters.
The overall objective of this internship is to explore the chemistry (reactivity, reaction pathways and kinetics) related to the atmospheric degradation of melamine in the aqueous phase.
This project will also aim to contribute to a larger research program devoted to the study of atmospheric processes (Labex CaPPA, CPER Ecrin). The work will take place at PC2A laboratory, Lille University and will be performed in collaboration with Prof. Roxana Suehring from Toronto Metropolitan University in Canada.
Key words: molecular simulations, atmosphere, melamine, reactivity, water

Research project S3*; The S3 project is mainly dedicated to bibliographical research, preparation of a future laboratory work, feasibility tests in agreement with the laboratory policies (No internship agreement will be signed for the S3 project). The payment of a bonus is not mandatory.
Research project S4*; The S4 project is a full time research training (5-6 months) and an internship agreement should be signed. Students must receive an internship bonus in accordance with university policies. Supervisors must provide the internship bonus.
* Preferably, both options will be selected. However, the student is free to choose another project in S4.
