Hsinchu County has total 4 air quality manual stations located in Zhubei, Chutung, Wufeng and Shanchi. In 2017, the frequency of implementation of the TSP monitoring program is twice a month, and the monitoring frequency of PM10 and PM2.5 is once a month, each monitoring time is 24 hours. TSP , PM10 and PM2.5 monitoring are in line with air quality standards(250, 125, 35 μg/m3). Hsinchu County TSP and PM10 measured in March is the highest value, PM2.5 measured in January and February are the highest value. Speculated that the reasons for the seasonal impact of high monitoring values. The monitoring results in 2017 are lower than previous years, showing an improvement in air quality. The 4 stations air quality artificial stations also perform the monitoring of dustfall, the amount of dustfalls between serious and very slight pollution levels.
This project conducts station maintenance work before performing monitoring at artificial station, and fully cooperate with the EPA air quality manual station counseling, EPAto HAC Laboratory to complete the inspection on Nov. 23, 2017 and complete the station site inspection operations and system guidance on December 13, 2017.
This project will implement the monitoring of the concentration of harmful air pollutants in the atmosphere of a station in accordance with the contract specifications. In line with the policy of the EPA, the monitoring time is adjusted to Q4, allowing the cumulative air pollutant concentrations in the four seasons of Hsinchu County. November 27-28, 2017 Twenty-two heavy metals in the TSP, 87 kinds of volatile organic compounds, 16 kinds of aldehydes and ketones, 17 kinds of compounds dioxin, 17 kinds of polycyclic aromatic hydrocarbons, 10 kinds of acidic alkaline gases were implemented at the Hukou automatic station of the EPB. This monitoring has detected trace amounts of heavy metals, Methanol, Acetonitrile, Acetone, Isopentane, Methylene chloride, 2-Butanone, Toluene, Formaldehyde, Dioxin, Naphthalene, Acenaphthylene, Acenaphthene, Fluorene, Phenanthrene, Benzalkonium, Pyrene, Benzene (g, h, i), Ammonia nitrogen.
Air quality micro-monitoring has completed the cloud platform construction that can receive PM2.5,temperature, humidity and other values at the same time and real-time connection can be displayed on-site values. It was set up at Chutung Automatic Station to carry out parallel comparison on April 24, 2017. The continuous monitoring results were returned with the manual monitoring results of Chutung Automatic Station, and regression was obtained to correct the monitoring result of the designated sites. As specified by the EPA, Hsinchu Stadium and Yamasaki Station were completed on August 14, 2017 and were continuously monitored for more than 120 days. The regression results were calibrated by parallel comparison.
There are altogether six environmental noises and six traffic noise monitoring stations in Hsinchu County, and each monitoring station performs two times of monitoring per quarter for twenty-four consecutive hours. The results of the noise monitoring in the four seasons in 2017 passed with 100%. In conjunction with the requirements of the EPB, the project performs noise monitoring on three expressways, one high-speed railway and one aviation. The work commissioned by the certification company. This year, the Environmental Protection Department's enforcement office have not issued any forecast of sandstorms. Therefore, no mobility monitoring was implemented.
