Abstract
Incineration is the major way for waste treatment in Taiwan. EPA of the ROC government has planed to build 30 municipal solid waste incinerators（MSWIs）. Currently, there are 19 MSWIs in operation with a daily treatment capacity of 21,000 tons. The emission of PCDD/Fs from MSWIs has been of great concern of the public. Therefore, large-scale surveys over the PCDD/Fs in ambient air were focused largely on the vicinity of MSWIs in the last three years. There were only several small-scale projects for ordinary areas that were implemented in northern and southern Taiwan.
The EPA started to set up the Taiwan Air Quality Monitoring Network（TAQMN）in 1990. For now, there are 72 air quality monitoring stations, including 58 ordinary ambient air stations, 5 traffic pattern stations, 4 background pattern stations, 3 industrial pattern stations and 2 national park pattern stations. The priority pollutants being monitored in TAQMN include PM10, sulfur dioxides, nitrogen oxides, carbon monoxide, ozone, and hydrocarbons. Besides, it also records several meteorological conditions. These stations were set up after proper evaluation and can well represent the air quality in the vicinity areas.
The most recent data for the concentration of PCDD/Fs in ambient air have shown a trend of deceasing level in many areas, but have not been reported in Taiwan. Therefore, in this study,15 TAQMN monitoring stations were selected as sampling sites for a nationwide survey from 2002 to 2003.
