Currently, 84 manufacturers have set up plants in Pingnan
Industrial Park, with 41 registered under control as fixed
pollution sources, 38 not registered (2 not operating), 3 under
suspension, and 2 under construction.
The project has completed 4 sets of air quality monitoring
(n=8). Judging by wind speed and direction during the
monitoring period, the effects of Pingnan Industrial Park on the
air quality of Jiadong and Fangliao areas were not significant,
and remained most affected by seasonal changes and human
activities in the vincinity.
The average dioxin level in the surrounding air, measured 4
times, was 0.032 pg I-TEQ/m3(n=4, equivalent to 0.034 pg
W-TEQ/m3), which was the second lowest of the historic average
values, slightly higher than the monitored level in 2011, and far
lower than the annual average value of 0.6 pg W-TEQ/m3 of the
Japanese air quality standard. Our measurement showed that the
presence of industrial park did not significantly affect the dioxin
level in the air of the surrounding areas; the level of
concentration was similar to the garbage incinerator in Taitung
County and certain areas in rural Spain.
The average biological dioxin level is 0.283 pg W-TEQ/g-fat,
and analysis from each sample found dioxin level that is lower
than the average background concentration from DOH's 2003
food investigation, and lower than the limit value promulgated by
the DOH's Guideline on Dioxin Processing In Food for poultry
meat products. The average dioxin level in plants was 3.024 pg
I-TEQ/g.d.w., which was equivalent to the concentration ranges
in lichens of Luxemburg, and Banyan tree leaves in areas
surrounding 3 garbage incinerators in Yongkang, Tainan City;
Linnei, Yunlin County; and Beitou, Taipei City. Main
component and clustered analysis on 17 characteristic species
have showed that the dioxin level in this year's media samples are
related to the secondary aluminum smelting. Fingerprint
characteristics are more susceptible to the effects of high chlorinespecies; however, since the TEQ of high chlorine species is
relatively lower, the effect on the human body is also lower.
This project conducted olfactometric analysis of odors and
possible sources of VOCs in 16 plants of the Pingnan Industrial
Park. 2 plants have exceeded the surrounding standard value and
were informed and penalized by the Environment Protection
Bureau; 5 plants approached surrounding standard value and
were suspected of odor pollution, and have been listed as key
inspection targets.
