Five-day biochemical oxygen demand (BOD5) and chemical oxygen demand (COD) for ethylene glycol and propylene glycol were determined for both Type I and Type IV anti-icer formulations in Corsi et al. (2012); values presented here are an average of the two. Acetate BOD5 and COD were determined for both liquid potassium acetate and solid sodium acetate pavement deicers in Corsi et al. (2012); values presented here are an average of the two. —, BOD5 results were not reliable for sodium formate.
