This work is study 71 kinds of volatile organic compounds (VOCs) in the sewer system of a metropolitan city during dry/wet weather. The VOCs contains alkanes, alkenes and alkynes, aromatics, chlorinated organics, sulfides, ketones and ethers. The purpose of this work estimated the emission rates of VOCs and cancer risk within 12 kinds of hazardous air pollutants (HAPs) will be part of the investigation 26 HAPs by using risk assessment.
TVOCs (concentrations of total VOCs) in dry weather was higher than that in wet weather for both sewer systems. The concentration distributions of dominant were KB7 (C3) in the A (B) sewer system. This system collected sewage from harbor and industrial park. During dry and wet weather, the most common VOCs were chlorinated organics and alkanes in the A sewer system, respectively. The main contribution were chloroethene and isopentane; the most common VOCs were aromatics in the B sewer system. The main contribution was m / p-Xylene.
This results show that the most emission rates of TVOCs is C3 (13,834.79 mg/hr) during dry weather and KB2 (1875.25 mg/hr) during wet weather. The emission rates of K1
