Gas-phase hydrogen peroxide (H/sub 2/O/sub 2/) and formaldehyde (HCHO) were measured in Glendora, California from August 14-21, 1986. These measurements were part of the Carbonaceous Species Methods Comparison Study sponsored by the California Air Resources Board. Both of these species were measured using enzymatic techniques: H/sub 2/O/sub 2/ by the peroxidase catalyzed dimerization of p-hydroxyphenylacetic acid and formaldehyde by the formaldehyde dehydrogenase catalyzed reduction of NAD/sup +/ to NADH. Both H/sub 2/O/sub 2/ and HCHO showed a strong diurnal variation with the highest concentrations measured during the period of maximum photochemical activity. H/sub 2/O/sub 2/ concentrations ranged less than 0.1 ppbv at night to a maximum of 3 ppbv for the hourly average on one day. The HCHO concentrations ranged from a low of 5 ppbv at night to a maximum of 20 ppbv during the day.
