This plan includes work items as follows: (1) Monitoring of hazardous air pollutants; (2) Monitoring of heavy metals in the air and factory chimney detection; (3) Monitoring of dioxin in the air and factory chimney detection; (4) Industry-specific surveys (5) Using scientific instruments to trace the source of pollution; (6) Review of the plan for emergency response to air pollution.
This project, started from 26th March 2020 till 31th Decenber 2020, was empowered by a contract which issued by the Bureau of Environmental Protection, Tainan city. Summaries of work items are as follows:
1.Dioxin monitoring and inspection operations
This project implements dioxin environmental monitoring for four seasons, and the sampling location is Yongkang District (Yongkang Industrial Zone Service Center).
Analyzing the monitoring results of dioxin, and comparing with the monitoring results of dioxin, furans and PCBs in the air in general air quality monitoring stations across the country, there is no obvious high situation.
In addition, the project also implements pipeline dioxin testing, and the test results didn’t meet the emission standards.
2.Heavy metal monitoring and inspection operations
This project implements heavy metal environmental monitoring for four seasons, and the sampling location is Yongkang District (Yongkang Industrial Zone Service Center).
Comparing the monitoring results with the previous results, it is found that the concentrations of aluminum, copper, manganese, lead and hexavalent chromium are high. Among them, the heavy metal lead is the most obvious. It may be two factories in the industrial zone. Both of them are lead battery manufacturing industries. Therefore, priority is given to implementation The pipeline heavy metal inspection results meet the emission standards. The project also implements pipeline heavy metal testing for the electric arc furnace steelmaking industry and small and medium-sized incinerators, and the test results meet the emission standards.
3. Hazardous air pollutant monitoring operations
This project implements HAPs environmental monitoring, and this project conducts sampling at two locations during the four seasons.
Analyzing the monitoring results, the measured values of most species of volatile organic compounds (87 items), aldehydes and ketones (16 items) and polycyclic aromatic hydrocarbons (17 items) are mostly lower than the minimum concentration of the calibration line, but higher than the MDL concentration. The main species detected in the Annan District were acetone and toluene, while the new urban area was acetone, propane, methylene chloride and toluene. The main characteristic species of acid-base gas (10 items) was ammonia, which was detected.
4.Using scientific instruments to trace the source of pollution
This plan selects one industrial zone to implement pollution source tracing, from a large scale to the factories, and at the same time conduct preliminary inspections of the factories to confirm the facts of pollution.
According to the results of the inspection, 3 companies in Tainan Technology Industrial Park violated laws and regulations, and 3 companies in Science and Technology Zone violated laws and regulations, showing that the use of scientific instruments does have its effect.
5. Industry-specific surveys
This project is aimed at two upstream suppliers in the gravure printing industry, only one is located in Tainan. In addition, 51 inspections in the printing industry have been completed and established in the fixed pollution source database.
6. Review of the plan for emergency response to air pollution
In response to the implementation of the "Administrative Measures for Emergency Response Measures for Air Pollution Sudden Accidents", we have mastered the list of public and private places under the jurisdiction of the jurisdiction. A total of 89 places have been reviewed.
