| I am a Grade 11 student at Northern Collegiate Institute and Vocational School in Sarnia. When I'm not working on science fair projects, homework, or studying for exams, I enjoy reading, swimming, and sailing. Recently, I have helped younger students learn mathematics by being a Kumon instructor, and I am looking forward also to obtaining my lifeguard certification this summer. |

Approximately sixty percent of the thermal paper receipts investigated contained Bisphenol A, and forty percent contained Bisphenol S. The levels present were approximately ten million times higher than those reported for Bisphenol A in polycarbonate plastic baby bottles, banned in 2008 by the Canadian government. |
