Pollution Characteristic of VOCs during Straw Burning Period in Chengdu, China

Abstract:

Volatile organic compounds (VOCs) were analyzed in straw burning period and non-straw burning period in the center of Chengdu city. The results showed that the concentrations of TVOC during straw burning were significantly higher than that in the non-straw burning period in Chengdu. The main components were alkanes, aromatic hydrocarbons and esters in straw burning period while aromatic hydrocarbons, alkanes, esters, aldehydes and ketones as the main contents in the period of non-straw burning. The correlation of TVOC, SO₂, NO₂, PM₁₀, PM_2.5, CO, O₃ and the API index was discussed and the NO_X-sensitive of photochemical reaction type was determined by the ratio of TVOC / NO₂ during straw burning period.
