Short summary
Our research investigates the volatile organic compounds evaporative emission characteristics of China's typical representative vehicle regulatory standards. The emission factors, chemical composition characteristics and source profiles of volatile organic compounds were determined. The hydroxyl radical total reactivity and compositions of evaporative emissions were quantified, and identified key volatile organic compounds reactive species contributing to atmospheric photochemical processes.
Our research investigates the volatile organic compounds evaporative emission characteristics of...
