“…The H20: mixing ratios which we have measured to date are much lower than the 40-180 and 10-30 ppbv reported by Bufalini et al [1972] and by Kok et al [1978a] for polluted sites. Generally, they are also lower than the 1.2-2.6 ppbv reported by Kok [1980] …”

Tunable diode laser absorption spectroscopy has been applied to the determination of gas phase hydrogen peroxide in ambient air with sub-ppbv (parts per billion by volume) detection limits for measurement times of the order of minutes. The methods for calibrating the instrument and for assuring the absence of spectroscopic and sampling interferences at the level of our present detection limits are described. Ambient air monitoring with our system indicates that the hydrogen peroxide mixing ratio is often < 0.3 ppbv. Five-minute average mixing ratios of up to 2.9 ppbv have been measured at sites in southwestern Ontario, Canada, during the summer months of 1984 and 1985, while the highest 1-hour average value observed was 2.1 ppbv.

“…In Chiang Mai and Nakhon Pathom, the ranges of the monthly averages were from below the detection limit of 0.1 to 6.2 ppbv and 1.4 to 15 ppbv, respectively. The high levels in Nakhon Pathom were similar to levels in farmland in Claremont and Riverside, CA, USA, which showed strong diurnal variation (Kok et al, 1978).…”

Gas-phase hydrogen peroxide (H 2 O 2 ) is very harmful to plants when combined with ozone (O 3 ). Information on ambient H 2 O 2 concentrations, especially for long durations, is limited not only in Thailand and South East Asia but also in Japan. The objective of the present research was to accumulate data of H 2 O 2 concentrations over long durations in Tokyo and Thailand. Hydrogen peroxide concentrations were monitored at

“…Based on 7 such measurements, it was estimated that a diesel passenger car under idling conditions emits "' 10 ~g of H 2 o 2 per liter of exhaust (McKinney, 1984). A possible direct field observation of combustion-produced H 2 o 2 was made by Kok et al (1978), who observed an increase in ambient H 2 o 2 during a local grass fire.…”
