The Environmental Protection Administration (EPA) debuted an upgraded version of its environmental survey vehicle and its high-altitude air sampling technology on the outlying islands of Penghu County.
EPA Environmental Analysis Laboratory Acting Director Yen Chun-lan (顏春蘭) said the vehicle, donated by Delta Electronics last year, uses a soft chemical ionization proton transfer reaction time-of-flight spectrometer, which can monitor more than 300 gaseous pollutants that have the ability to bind with oxonium ions using.
The pollutants include volatile organic compounds, inorganic gases and a range of odorous substances, which make up the majority of gaseous pollutants, she said.

The vehicle also boasts quick sample analysis — capable of yielding results in less than 10 minutes — and can detect pollutants with concentrations as low as 0.01 parts per billion, Yen said.
The technology represents a major improvement on first-generation environmental survey vehicles, which can analyze about 56 pollutants and require up to one hour to produce results, she said.
The faster analysis would also speed up emergency response times to situations such as gas leaks, she said.
Other equipment on the vehicle includes a MS200 portable spectrometer and a Fourier transform infrared spectroscope (FTIR). Although both devices have a lower resolution than the chemical spectrometer, they can operate without an external power supply and can be used to detect escaping gases and pollutants in hard-to-reach areas, she said.
The FTIR uses an infrared spectrometer that shows the intensity of wavelengths projected by leaked gases, thereby identifying them, Yen said.
The equipment cost more than NT$15 million (US$479,202), she added.
The EPA deployed the vehicle close to the site of the recently Penghu Fireworks Festival in Magong City (馬公) to detect any surges in air pollutants caused by fireworks.
The results, produced between April 20 — the start of the festival — and June 15, showed margin increases in particulates under 10 micrometers, particulates under 2.5 micrometers and nitros oxide, which the EPA previously said were associated with fireworks.
The agency said that the phenomenon might be due to the high altitude at which fireworks explode, as environmental survey vehicles are usually monitor air quality near the ground.
The vehicle is to do an environmental surveillance mission at several industrial complexes and science parks, including Formosa Plastics Group’s naphtha cracker in Yunlin County, the Central Taiwan Science Park and Hsinchu Science Park, before being deployed in Kaohsiung, one of the municipalities most affected by air pollution, the EPA said.
Also debuted last month, the EPA’s high-altitude sampling technology, which uses a sampler attached to a balloon that can reach alttitudes of 700m to 1,000m to collect bacteria carried by air streams.
Laboratory researcher Yen Jung-hua (顏榮華) said that with the help of a high-speed motor, bacteria are sucked in by the sampler before falling on a petri dish where they are cultivated.
After bacterial colonies are formed, researchers conduct DNA sequencing to identify them, he said.
Comparing the results obtained in Penghu last month with others produced in New Taipei City’s Wanli District (萬里) between March and April 2013, when northeast monsoons blew across the nation, Yen said that there is no noticeable difference in the types of bacteria identified, and results from both tests showed bacteria commonly found in dirt and deserts.
So far, the laboratory has not detected any health risks associated with these types of bacteria, but would carry out more detailed analysis on days when northeast winds are strong to ascertain whether elevated concentrations of bacteria would affect people’s health, he said.
VOTERS’ CHOICE: The DPP’s Chen and independent candidate Huang conceded defeat before 7:20pm, with Chiang pledging to remain humble and do his best Legislator Chiang Wan-an (蔣萬安) yesterday won the Taipei mayoral election, with the Chinese Nationalist Party (KMT) candidate defeating the Democratic Progressive Party’s (DPP) pick, former minister of health and welfare Chen Shih-chung (陳時中), and former Taipei deputy mayor Vivian Huang (黃珊珊), an independent. After polling stations closed at 4pm, the Taipei Election Commission issued a preliminary estimate that voter turnout in the city was about 64 percent, slightly lower than in 2018. Chiang, 43, is to be the youngest Taipei mayor ever, with the KMT regaining the capital after eight years. Chen had an exceptionally high national approval rating when he was head
FAMILY BACKGROUND: Chiang was effective in running a cautious campaign to avoid making mistakes, waiting for other candidates to slip up, an analyst said Chinese Nationalist Party (KMT) Taipei Mayor-elect Chiang Wan-an (蔣萬安) stood out among his rivals due to his energy, his die-hard supporters and his relative openness to discuss issues such as same-sex marriage, a political analyst said yesterday. Chiang’s campaign was also aided by his family’s background in politics, which helped him garner greater support in Taipei where there is a large KMT base, said the analyst, who chose to remain anonymous. “Chiang is also not a typical KMT member when it comes to certain issues, such as gay marriage, and his more open stance widened his support base — particularly among young
First-time politician Mai Yamada’s (山田摩衣) Japanese name has attracted attention in Chinese-language media after her win in the New Taipei City Council election on Saturday. Born to a Taiwanese mother and Japanese father, the 32-year-old Taiwanese-Japanese stood out after becoming one of nine elected city councilors in Banciao District (板橋) in the nation’s local government elections on Saturday. Although she has a Japanese name, she grew up and was educated in Taiwan, Yamada said, adding that “Taiwan is my home.” Before running for local government, Yamada, who speaks fluent Japanese and English, was Legislative Speaker You Si-kun’s (游錫堃) secretary. She has been involved in
Mask easing: Teachers are allowed to take their masks off while lecturing indoors, but students should keep theirs on, as COVID-19 measures ease this week The Ministry of Education (MOE) yesterday released new on-campus COVID-19 prevention guidelines, stating that masks can be taken off while exercising, singing, dancing, performing, taking photographs, dining, drinking, video and voice recording, hosting events, presenting speeches and lecturing outdoors. Large outdoor events organized by schools should comply with the mask regulations issued by the Central Epidemic Command Center (CECC), it added. The new guidelines came into effect yesterday, and people in Taiwan are no longer required to wear masks outdoors for the first time since May 19 last year. The CECC announced the easing of the mask mandate on Monday, adding that it
