This project started on year 2012 April 2nd, which included two fixed locations to conduct the infrared continuously monitoring (OP-FTIR) for 180 days on the one hand, and one the other to conduct harmful pollutants detection operations within and outside the region which include: the volatile contaminants (VOCs), polycyclic aromatic hydrocarbons (PAHs), and the metal elements for offshore industrial zone. The establishment of offshore industrial zone adjacent sensitive background concentration data as the basis for subsequent monitoring and for further understanding offshore Islands Industrial Zone and its impact on neighboring area through the effective implementation of this project were mostly achieved.
This project was completed as follows:
1. it integrated the offshore industrial zone’s monitoring resources to identify the pollution sources.
This project used hazardous air pollutants data to supplement the insufficient sampling number of the risk assessment plan and follow-up analysis and meteorological data were provided in the form of electronic files to the risk assessment plan. In other aspect of clarifying pollutants, the working team collected data surrounding Taihsi photochemical station, aggregated petition information, and compared detection information around outlying islands.
2. It used infrared continuously monitoring operations to explore the offshore industrial zone’s impact on its surroundings in different season.
This project applied two OP-FTIRs to measure Feng An and Nan Men two survey lines for at least 180 days and the results summarized as follows:
2.1 Feng An survey line: This line showed the maximum concentration of ethylene, propylene and ammonia to be relatively high. In previous monitoring results, the average concentration of ammonia got the highest 17.64 ppb, then propylene to 10.72 ppb and ethylene to 8.63 ppb. The non-zero average concentration for the highest was ethylene 276.34 ppb, then propane to 199.53 ppb, propylene to 149.79 ppb. From this line, ammonia appeared frequently and its frequency of occurrence up to 72.82%.
2.2 Nan Men survey line: This line showed the maximum concentration of ethylene and propylene to be relatively high. In previous monitoring results, the average concentration of propylene got the highest 76.35 ppb and ethylene to 36.77 ppb. The non-zero average concentration for the highest was propylene 329.24 ppb, then ethylene to 226.55 ppb propane to 103.91 ppb. The previous frequency of occurrence by ethylene, propylene and ammonia were measured up to 29.24%, 25.16% and 42.46% respectively.
3. The expansion of CO2 monitoring equipment’s explored CO2 concentration distribution inside and outside industrial zone.
This project completed 3 sets CO2 analyzers on June 28th 2012 respectively located in the Sixth Naphtha North Gate Dormitory, Shang Der and Giau Tou Elementary Schools.
From collected data of Yulin county's five stations’ CO2 analysers , the Xinsin Elementary School showed its 462.21 ppm relatively high data compared with the average data of each station and the Sixth Naphtha South Gate Dormitory quarters showed its 423.79 ppm relatively low data. The maximum day and night value/minute were in Sixth Naphtha Cracker Factory perimeters including North Gate and South Gate dormitories which showed higher CO2 concentration may have been a factory impact.
4. It investigated trends and distribution characteristics of offshore industrial zone factory in the concentration of polycyclic aromatic hydrocarbons (PAHs).
The seasonal concentration trend of PM2.5 particles of T-PAHs in offshore industrial park showed autumn > summer > spring. Possibly industrial area of PAHs (Ind-of PAHs) was consisted by NaP, ACPy, ACP, FLU, ANTHR, PHE and FLT; Ind-of PAHs in the dust also appeared the same trend. In addition, Me-PAHs belonged to mobile pollutant had the higher characteristic and daytime concentration had been about double compared with night time concentration. PCA analysis showed that the pollutants contribution from the industrial process, coking plants, oil combustion and traffic sources.
5. It established the PAHs’ fingerprint characteristics on offshore Islands industrial zone.
The current data showed that fingerprint characteristics of offshore industrial park in Ind-PAHs were possibly consisted by NaP, ACPy, ACP, FLU, ANTHR, PHE, FLT, and Me-PAHs.
6. It investigated PAHs’ concentrations trends and distribution characteristics of the Yunlin area.
The seasonal concentration trend of T-PAHs of the PM2.5 particles in neighboring industrial areas and away from the industrial area showed autumn> summer> spring. According to the current results showed that Ind-PAHs in the neighboring industrial area has transmission phenomenon; additionally, PAHs of BkF, BeP, IND and BghiP took the higher proportion. Away from the offshore industrial area, the main classification of PAHs was traffic sources of Me-PAHs PYR, BaA, ANTHR, etc. According to the result of the PCA statistical analysis, the neighboring industrial area would be affected by the industrial process of the industrial area, steelworks, incinerator, traffic sources and coal-fired power plants or biomass burning; away from the industrial area (Yuan-Chang) was affected by the nearby Yuan-Chang industrial area, the Sunny Friend medical waste incinerator, traffic sources, and biomass burning.
7. It assessed the offshore industrial zone’s PAHs emissions impact on Yunlin.
The current data showed that the emission of Ind-PAHs in the offshore industrial area might affect nearby industrial areas including industrial process, coking plants, traffic sources, and coal-fired power plants or biomass burning.
8. It provided the monitoring result of hazardous air pollutants in the offshore industrial zone and the follow-up risk assessment.
The measurement of hazardous air pollutants in this project mainly including VOCs, PAHs and metal elements, the results as follows:
8.1 Volatile Organic Compounds: this year's measured compounds of testing result were acetone, 2 - butanone, toluene, propane and methanol, and the measured distance in the offshore industrial zone within 10 km (Xinsin Elementary School, Haifeng Elementary School Branch, Feng An Elementary School and Lun Feng Elementary School) showed the number of measured species were significantly more and relatively high concentration, in which n-hexane, ethyl benzene and acetonitrile were not measured 10 km away from measured points, and the methylene chloride and 2 - butanone were significantly higher than the concentration of the other range of measurement points. In addition, this year the district Run 12 times detection with respect to outside the 14 compounds detected in this district detected a total of 26 kinds of compounds containing 1,3-butadiene, 1,2 - dichloro-B such as alkyl and acrylonitrile were offshore industrial zone indicator pollutants.
8.2 The Metal Elements: For seasonal distribution of total concentration of heavy metals in PM2.5 particles showed the same trend as PM2.5 concentration; it was autumn > summer > spring. As a result, it was estimated Ind-metal of industrial area were consisted is possibly with Ni, Cu, Cr, Co, Cd, Se, and Hg in the current project.
