VOCs emission characteristics based on emission links of representative enterprises in a typical Chemical Industry Park in Pearl River Delta were investigated. Sampled by TENAX tubes and analyzed by Gas Chromatography-Mass Spectrometry (GC-MS), the VOCs concentrations and compositions of different emission links as well as the exhaust funnels were obtained. Cluster analysis of VOCs compositions presented six classes existing, and the amount of VOCs in 2014 was calculated based on emission links. The results showed that the VOCs concentrations in each emission link of representative enterprises were 0.2~107.02mg/m3, almost all samples were above 10mg/m3 and 1~34 times higher than that of enterprises' boundary concentration, which illustrates that the leakage of devices was serious. The VOCs composition of different factories or different emission links were diversity and alkane was the main pollutants, followed by benzene series and OVOCs. In addition, the detected compositions were inconsistent with raw materials in majority of factories expect storage and transportation enterprise, probably because of interreactions or by-products formation in factories. The amount of VOCs of each factory was less than 100t/a expecting YH storage enterprise, which amount was 1864.97t/a, and discharged mostly by fugitive emission.
