Abstract Introduction The on-going substance use crisis has led to unprecedented rates of hepatitis C virus (HCV) in Canada, with increasing positivity among women who use drugs (WWUD). Despite efforts to reduce barriers to HCV testing and treatment, follow-up remains a major issue.

The stable carbon kinetic isotope effect (KIE) of ethane photo-oxidation by OH radicals was deduced by employing both laboratory measurements and theoretical calculations. The investigations were designed to elucidate the temperature dependence of KIE within atmospherically relevant temperature range. The experimental KIE were derived from laboratory compound specific isotope analyses of ethane with natural isotopic abundance exposed to OH at constant temperature, showing ?
