Cooking is one of important emission sources of fine particles(PM_(2.5)). This study using the catering enterprises of Shanghai as an example,presents a method to estimate the PM_(2.5) emission inventory from cooking according to the number of stoves,cooking time,and number of customers. Based on in situ measurements,the concentrations of PM_(2.5) emissions ranged from 0. 1 mg·m~(-3) to 1. 8 mg·m~(-3),which exceeded the limit(1. 0 mg·m~(-3) for lampblack) in the national standard. Organic carbon dominated t...
