Ambient air monitoring of Beijing MSW logistics facilities in 2006

Abstract

In China, "green" integrated waste management methods are being implemented in response to environmental concerns. We measured the air quality at several municipal solid waste (MSW) sites to provide information for the incorporation of logistics facilities within the current integrated waste management system. We monitored ambient air quality at eight MSW collecting stations, five transfer stations, one composting plant, and five disposal sites in Beijing during April 2006. Composite air samples were collected and analyzed for levels of odor, ammonia (NH3), hydrogen sulfide (H2S), total suspended particles (TSPs), carbon monoxide (CO), sulfur dioxide (SO2), and nitrogen dioxide (NO2). The results of our atmospheric monitoring demonstrated that although CO and SO2 were within acceptable emission levels according to ambient standards, levels of H2S, TSP, and NO2 in the ambient air at most MSW logistics facilities far exceeded ambient limits established for China. The primary pollutants in the ambient air at Beijing MSW logistics facilities were H2S, TSPs, NO2, and odor. To improve current environmental conditions at MSW logistics facilities, the Chinese government encourages the separation of biogenic waste from MSW at the source.

Role of Garbage Classification in Air Pollution Improvement of a Municipal Solid Waste Disposal Base

“…14 Li et al reported that the concentration of H 2 S in the air around a land ll in Beijing was less than 36 ppb. 15 The concentration of H 2 S in the ambient air of land lls in Korea, Spain, and the US is in the ppb level. 16-18 H 2 S pollution levels were relatively low in the base before garbage classi cation.…”
