This project started on April 16, 2013, 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 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:
1.1 The species what were over Odor threshold were ammonia and 1,3- butadiene. 1,3- butadiene was measured in Nan Men survey line and it was measured in last fall (September), this year’s summer (June) and winter (November).
1.2 Compared with the concentration trends of ethylene, propylene and propane those were detected from Taihsi photochemical station and OP-FTIR, we cound conjecture legitimately that the VOCs concentrations of ambient areas were obviously affected by the Sixth Naphtha Cracking Project Industrial Zone.
1.3 In Nan Men survey line, the high relatively values of ethylene, propylene and propane were detected in fall and winter. The wind direction were northeasterly and upwind area was the Sixth Naphtha Cracking Project Industrial Zone. In Feng An survey line, the high values of Ammonia was detected in summer and the high relatively values of ethylene was detected in May and September. The wind direction in May was from west to southwest and that in September was from west to westnorth. In both periods, the upwind area was the Sixth Naphtha Cracking Project Industrial Zone. Therefore, we cound conjecture that survey results of two survey lines were affected by the Sixth Naphtha Cracking Project Industrial Zone.
2. The investigation on trends and distribution of the concentrations of polycyclic aromatic hydrocarbons (PAHs) and heavy metals on offshore industrial area.
The sources of PAHs in PM2.5 particles were industrial emission (ACP、ACPy、PHE、ANTHR and FLT) and mobile pollutant Me-PAHs(1-MeNAP、2-MeNAP、3-MePHE and 3,6-DMP) on offshore industrial area. Additionally, NAP、FLU、BNT、BaA and BeP also took the higher proportion. The industrial emission PAHs were ACPy、ANTHR and FLT in dry deposition. And the PAHs were 2-MeNAP、3-MePHE and 2-MePHE in mobile pollutant. The heavy metals in PM2.5 particles were consisted of Cd、Se and Hg from industrial emission, Pb and Zn from mobile pollutant and V from heavy oil combustion. PCA analysis was shown that the pollutants on offshore industrial area originated in industrial process, steel industry, incinerator, coal fuel and traffic sources.
3. The establishment of the fingerprint characteristics of PAHs and heavy metals on offshore industrial area.
The current data and the data from papers showed that fingerprint characteristics of Ind-PAHs on offshore industrial area were possibly consisted of ACP、ACPy、ANTHR、PHE、FLT and Me-PAHs. The fingerprint characteristics of Ind-metals were possibly consisted of Ni、Cu、Cr、Co、Cd、Se and Hg.
4. The investigation on trends and distribution of the concentrations of PAHs and heavy metals on Yunlin area.
The concentration of low molecular weight PAHs in PM2.5 was the highest on offshore industrial area. The result showed that the initial emission of PAHs from offshore industrial area was partial to low molecular weight. According to the ratio of Ind-PAHs/(Total-PAHs - Me-PAHs), the ratio was the highest on offshore industrial area no matter in day or night. The ratio on the offshore industrial area, the neighboring industrial area and away from the industrial area was higher in day than in night. The concentration of Ind-PAHs in dry deposition was the highest on offshore industrial area. The result showed that there was an influence of emission of PAHs from industrial source on environment. No matter in day or night, there was the highest concentration in total heavy metals on offshore industrial area. Besides, the total concentration of heavy metals was higher in day than in night. The total heavy metals and Ind-metals in dry deposition were significant the lowest on away from the industrial area.
5. The assessment of the influence of PAHs and heavy metals from offshore industrial area on other areas in Yunlin.
In this project the assessment of the influence of the offshore industrial area on other areas in Yunlin was devised by analysis of PAHs and heavy metals. The result showed that the PAHs and heavy metals in dry deposition, and low molecular weight PAHs in PM2.5 were the highest on offshore industrial area. As mentioned above, the PAHs and heavy metals in coarse particles, and the gas PAHs were more significant in representing the situation of pollution from industrial area. According to the result of PCA statistical analysis, in PM2.5 the mainly pollutant source was originated in industrial process, steel industry, incinerator, coal fuel and traffic sources on offshore industrial area. There was a tendency toward mainly pollutant source on the neighboring industrial area as the same on offshore industrial area. The mainly pollutant source on the away from the industrial area was from traffic sources and the emission from industrial area. In dry deposition, the source of pollutant from earth-crust elements distributed over three areas. Moreover, the mainly pollutant source was originated in industrial process, steel industry, coal fuel, coking plants and traffic sources on offshore industrial area and neighboring industrial area. The mainly pollutant source on the away from the industrial area was from coal fuel, coking plants, industrial process, incinerator, biomass burning and traffic sources. It might be influenced by local traffic sources and the emission from industrial area.
6 The VOCs surveys in Sixth Naphtha Cracking Project Industrial Zone and perimeter were to understand the trends of the concentration changes.
6.1 From the survey results, we can understand that the closer the Sixth Naphtha Cracking Project Industrial Zone, the measured species more.
6.2 To calculate the average concentration of the every species in each area, we could found that most species were detected within 10 km ,or we could also found that the average concentrations within 10 km were larger than that of the other distance.
6.3 Chloroform was detected in Feng An Elementary School. Methylene Chloride was detected in Feng An Elementary School, Lun Feng Elementary School, Haifeng Elementary School Branch and Xinsin Elementary School where those were near the Sixth Naphtha Cracking Project Industrial Zone. Though Methylene Chloride also was detected in Cihtong junior school and Huwei junior school, species concentration was relatively low.
6.4 to compare the survey results of nearby 14 schools, 6 spots of the factory districts were detected more species obviously.
