ABSTRACT
Currently, there are eighty- three factories in the Pingnan
Industrial Park. Among them, forty-one factories are regulated
under the “Stationary Pollution Source Installation and Operating
Permit Management Regulations” (three of them are suspended
voluntarily). Thirty-seven factories are not regulated under the
“Stationary Pollution Source Installation and Operating Permit
Management Regulations” (five of them are suspended
voluntarily). Four factories are temporarily suspended. The other
factory is under construction.
This project is conducted air quality monitoring for 6 times at
three consecutive quarters. The results of the air quality
monitoring indicate that only the average concentration of O3
between 1 to 9 pm on the 24th of May, 2010 is higher than
maximum allowable limits, the rest of the results of the air
quality monitoring are lower than maximum allowable limits.
The air quality is between the ones assessed in year 2007 and
2008, and the changes of the O3 concentration might be due to
the changes of the regional air quality.
In this survey, the average concentration of dioxin (from
eight samples at four consecutive quarters) is 0.071 pg I-TEQ/m3
(which is 0.077 pg I-TEQ/m3) lower than the average 0.104
I-TEQ/m3 sampled at the same area in 2007. It is also lower than
the Japan’s 0.6 pg I-TEQ/m3 maximum allowable limits, but is
higher than 0.033 pg I-TEQ/m3 at the same area in 2008. The
concentration range of dixion is similar to the concentration
range before the construction of incinerator in the agricultural
surroundings in Italy as well as the similarity of surrounding
areas of the Letzer Incineration in Yilan in 2005.
The average concentration of dioxin sampled from the
aquatic species in 2010 is 0.331 pg I-TEQ/m3, which is lower
than 0.903 pg I-TEQ/m3 (the average concentration sampled in
2007), but is higher than of 0.172 pg I-TEQ/m3 (the average
concentration sampled in 2008). The overall average
concentration of dioxin sampled from the aquatic species is lowerthan the maximum allowable limits of 4 pg I-TEQ/g.w.w. set by
the National Department of Health. The overall average
concentration of dioxin sampled from the plant is 2.788 pg
I-TEQ/g.d.w., the result range is similar to the average
concentration of dioxin sampled from moss of urban areas in
Luxembourg and as to the average sampled from the leaves of
Banyan at the surrounding areas of Miaoli Incineration.
In addition, This project also analyzed the the results of
dixion survey by using the principal component analysis and
cluster analysis and target species analysis. Based on the findings
of the three analysises mentioned above, among all the pollutants
of dixion, the secondary aluminum smelting has influenced the
surroundings of the Park significantly.
Hence,this project aimed at the four factories which produce
the materials containing “high-risk species that should give
priority to filing” and the industrial district sewege treatment
plants to conduct the examinations of the odor species and
surrounding VOCs. The findings of the study found that no
pollutants above the maximum allowable limits of odor species
or only a trace of concentration. As for the surrounding VOCs,
other than Shin Foong and Hsinhwa and Kao Hsing Chang’s
propylene nitirle and methyl methacrylate higher than the odor
threshold value, the average concentrations of the rest of the
factories are far lower than the odor threshold value.
