This project started on April 1th 2011 and it contained following working targets including the 180 days' continuously Open Path FTIR (OP-FTIR) infrared monitoring (OP-FTIR) in sensitive sites of the off-shore Island's industrial district, and the analysis of harmful pollutants examination at 14 schools and 2 places in the off-shore Island's industrial district. The harmful pollutants examination contents included: Volatile Organic Compounds (VOCs), Polycyclic Aromatic Hydrocarbons (PAHs), heavy metals, acid and alkali gas and particles and so on. The main purpose of this project is firstly to establish the background data in sensitive sites of the off-shore Island's industrial district for the future follow up comparative monitoring and secondly to understand the impact of pollutants coming from off-shore Island's industrial district.
Each executed achievements of this plan were listed as below:
First, this plan unified the Sixth Naphtha Cracking Project Industrial Zone existing monitoring resources to carry on the clarification of pollutant sources.
This plan utilized harmful air pollutant examination work to make up the insufficiency sample number of risk assessment plan, and all requested VOCs, PAHs and the Metal sampling and the analysis method were the same as the risk assessment plan, following obtained analysis and the meteorological data material all would be provide by the electronic file form for the risk assessment plan to use. In plan execution period, matching the Islands conformity plan in the Islands industrial district sampling plan, there were 3 times complimentary sampling, and in carried out for the first time in 6/23~6/24 using OP-FTIR synchronization monitoring.
Secondly, to coordinate VOCs and the stink material monitoring work is to grasp precisely the possible material ingredient and the origin which causes the stink events. This plan carried out at least 180 day-long monitoring by two sets OP-FTIR in 6 places of this county and collected the labor safety accidents and the populace appealing cases. Its achievements were summarized as follows:
(1) on May 5th at 22:36pm, populace stated one case in the material, i.e. the place was in the southeast gate of Tonghuan Road in the Sixth Naphtha Cracking Project Industrial Zone and the inspector also discovered unusual smell in the scene (wind direction was northeast), this measuring point obtained ethylene 54.19 ppb in 23:36PM, the wind direction was north north-east, which reflected the consistent result as the inspection.
(2) The Sixth Naphtha Cracking Project Industrial Zone occurred labor safety event with the fire, the Lunfeng Primary School obtained the vinyl chloride (the greatest density to reach as high as 217.94 ppb), the same time interval ethylene and the propylene also synchronized the high value occurrence approximately 4 hours after the fire (wind direction northwest ~ north wind; The wind speed approximately 2.1~2.4 m/s). In addition, the pleading case also carried on the canister sampling in 22:20pm in Formosa Plant Northeast gate, at that time the wind direction was the western wind, in the test result namely contained vinyl chloride 389 ppb, demonstrated that in this labor safety event, the vinyl chloride had dissipated truly to nearby area.
(3) In the pleading case, The Fengan Primary School received the unusual smell at 14:50pm on July 1st and the scene wind direction was a northwest wind. Around the same time in 14~15:00 the Sinsin Primary School, obtained 2.4~18.5 ppb the methyl alcohol separately, the wind direction was the north north-western wind, because the Sinsin Primary School located at the south side of the Fengan Primary School, compares its wind direction, the evaluation should have suitable correlational.
(4) The Sixth Naphtha Cracking Project Industrial Zone had labor safety events in 7/26 and 7/30. This plan set up the OP-FTIR monitoring facilities in the Haifeng Branch School and the Taici Secondary School respectively. By 7/23~8/3 Chroma graph analysis, mainly lied in 7/27~7/29 to have the high density ethylene, the propylene and the butane, the neighbor Haifeng Branch school measuring point obtained the high density the ethylene (172.5 ppb) and the butane (621.83 ppb).
Third, to use the monitoring data coordinated with meteorological data and the pollution ingredient characteristic provided the related control plan to control the pollution and maintain the good air quality and the living conditions.
Besides this plan carried on the harmful air material monitoring in the Islands industrial district and the ambient environment, it still had the Islands conformity plan and the risk assessment plan; this plan’ execution would be carried on crosswise contacting with two plans, and collected this county overall air pollutants distributed situation to be brought to the environmental protection bureau making the pollution control and the counseling basis.
Fourth, to build the Sixth Naphtha Cracking Project Industrial Zone monitoring data integrated platform with the aim of collecting the entire monitoring result effectively.
This plan integrated risk assessment plan to execute harmful air pollution test result showed total VOCs examining 96 samples, particle condition PAHs examining 82 samples, gaseous state PAHs examining 68 samples, the heavy metal examining 82 samples and the sour acidic material examining 80 samples, and collected the entire induction in this report.
In addition, to integrated the project “Air Pollutant Information Integration in Coastal Industrial Park” six times the volatile organic compounds investigation executions (altogether examining 72 spots) in the Islands industrial district, its result pointed out separated 157 kinds of volatile organic compounds, the harmful air pollution species have 43 kind, occupied the total 27%, in addition by the total species time looked that the idea has 358 kind of times, the harmful air pollution species number has 142 kind of times, accounted for the total species number of times 40%, looking from each examination species number presented 96 kinds by the second sampling.
But the second sampling region all in the light petroleum factory, next distributed for the fourth sampling 81 kinds of its sampling points in Formosa Plastics Group MMA, AN, C4, AE, plastifies OL-1, AROMA-1, PTA, PS, HAC, the Formosa Petrochemical corporation Waste Water Factory, but each sampling harmful air pollution species number picked out most much was the fourth sampling (33 kinds), next for the third sampling (29 kinds). From the examination density analysis, the acrolein had three points showing data respectively was 3.8 ppb, 2.1 ppb and 29.7 ppb surpassed the control standard (2 ppb), and other spotz conformed to the control standard.
Fifth, to conduct the harmful air pollutant (including: more than 16 kinds of PAHs, VOCs and 20 kind of heavy metals) monitoring in the Sixth Naphtha Cracking Project Industrial Zone nearby areas.
This plan completed in the Sixth Naphtha Cracking Project Industrial Zone 2 spot positions and 14 schools total 16 spot positions including the VOCs, PAHs and the heavy metal analysis, the result was as follows:
in (1) VOCs analysis result, took 1, 3 pyprolylene, the vinyl chloride, 1, 2- dichloroethane and the propylene nitrile as the target pollutants in the Islands industrial district, You Yi in May (prevailing wind for northwest wind) and in September (prevailing wind for western wind), Mailiao Town and the TaiXi Town located at the Islands industrial district leeward place, two place most measuring points have obtained 1, 3 pyprolylene and the vinyl chloride; In addition in the factory district 6 spot time monitoring result, obtained 36.68 ppb in methyl methacrylate factory (MMA) the methyl methacrylate, or obtains 26.2 ppb in propylene nitrile factory (AN) the propylene nitrile…And so on, the majority of data demonstrated that has obtained the measuring point in the factory district representative pollutant. As stated above, might know the pollutants by the factory district inside and outside testing result showed the escape question still exist and had to strengthen the pollutants control.
in (2) From the polycyclic aromatic hydrocarbon sample analysis result, it carried on the analysis by PAHs/PM2.5. We found PAHs occupying PM2.5 proportion obviously and taking the factory as measuring point with high percentage, especially four link's B[k]F and Chry, five link's DBA, six link's B[ghi]P accounted for the high proportion.
in (3) From the heavy metal sample in ambient air analysis result,it carried on the analysis by metal ingredient /PM10. We found the metal ingredients occupying PM10 obviously and taking the factory measuring points with highest percentage, next for high exposed zone, exposed group, control group as lowest; In the measuring point accounted for the proportion in the factory in which Cu was higher than other categories, next is V, Ni, Co, Se, Cr, and its proportion size gradually reduces from inside the factory to the outside, because Cu is the industrial pollution target, V, Ni and Cr discharge from the fuel oil factory and the coal-burning power plant, Co possibly comes from the refinery system regulation exhaust, therefore may regard as of feature element pollutant of the factory district emissions.
Sixth, the investigation the side volatilizes organic gas (VVOCs), the ozone and the ammonia continuous monitoring in the Sixth Naphtha Cracking Project Industrial Zone five kilometers scopes.
This plan from 2010 in the Fengan Primary School, Sinsin Primary School, Liufeng Primary School and Haifeng Branch School carried out volatilizes the organic gas monitoring mainly obtained the ammonia, the methane, the ethylene and the ether. Year 2010 monitoring result consisted by ammonia, methane and ethylene primarily, although was high by the methane density, but its characteristic for tasteless, was still take the ammonia as the main stink origin.
In this plan monitoring result, the density of the ammonia in the night was higher than the day, in addition the ammonia continuous monitoring data demonstrated also high at night density, because in this county governed the most animal husbandry, obtained the ammonia in various measuring points, its wind direction usually coming from various positions, and not obvious fixed origin.
Seventh, to carry on the monitor in view of the acid-base gas and the particle, the matching meteorological data and the discussion unusual smell and the particle to influence on the neighbor campus.
This plan completed in the Sixth Naphtha Cracking Project Industrial Zone 2 spot positions and nearby 14 schools with the total 16 spot positions the acid-base gas and the particle examination analysis, the result as mainly obtained the species take the ammonia, in the factory district the maximum value was 41 ppb, the high exposed zone maximum value was 86 ppb, the exposed zone maximum value was 100 ppb, the control farm plot maximum value was 76 ppb. Demonstrated that factory district system process had the ammonia escape, but outside border possibly because of animal husbandry influence, will cause outside the border perhaps the farther control group measuring point will obtain the high density the ammonia. Regarding the campus environment's influence, must carry on the long-term monitor, and judges the unusual smell type, avoids judging the Islands industrial district influence by the ammonia achievement the target.
Eighth, the weather station installation was agreed by the bureau, the work team on June 30 of 2011 completed 3 weather stations in Formosa Plan North Gate Dormitories, the Chiautou Primary School and Shander Primary School.
