摘要: Abstract Ambient oxidant concentrations have been monitored at Toronto, Canada since 1970. During the first 2 years of survey, more than 100 hourly in excess 10 pphm were observed. In summer months, high concentration levels appeared to result from photochemical reactions they accompanied by daily fluctuations primary and secondary pollutants characteristic activity. Simultaneous analysis monitoring data continuous records meteorological parameters showed that occurred on days temperatures, long solar irradiation periods sourtherly winds. The indicated precursors may originated sources south Toronto.
