Environmental Protection Administration (EPA) Minister Wei Kuo-yen (魏國彥) yesterday said that the agency is mulling banning vehicles and reducing electricity generation when air pollution spikes to combat heightened levels of PM2.5 — fine particulate matter under 25 micrometers in diameter.
In a question-and-answer session at a meeting of the Social Welfare and Environmental Hygiene Committee at the legislature in Taipei, Wei said the EPA would announce a set of emergency measures against serious air pollution, including three action plans in response to three different levels of pollution.
Operations at factories would be limited and burning of paper offerings banned when air pollution reaches “primary levels”; when pollution reaches “medium levels” heavy-duty diesel trucks and two-stroke scooters would be prohibited, while the power industry would have to reduce its emissions by 20 percent; and private vehicles would be banned and the power industry would have to reduce its emissions by 40 percent when pollution reaches “emergency levels,” Wei said, without specifying the criteria used to differentiate the pollution levels.
The top three contributors of PM2.5 emissions are heavy-duty diesel trucks, cooking fumes and the power industry, accounting for 9.53 percent, 6.13 percent and 5.6 percent of total PM2.5 emissions respectively, the EPA said.
Other vehicles — trucks, buses, cars and motorcycles — contribute 20.37 percent of total PM2.5 emissions, the agency said, adding that emissions from transportation must be reduced.
The draft emergency measures would also include natural gas-fired power plants, in addition to coal-fired and fossil-fuel power plants, because PM2.5 pollutants also derive from nitrogen oxides emitted by gas-fired power plants, Wei said.
Meanwhile, the Democratic Progressive Party (DPP) caucus held a press conference yesterday, calling on the EPA and the Ministry of Education to unify regulations concerning their pollution response mechanisms and air pollution holidays for schools.
DPP Legislator Tsai Chi-chang (蔡其昌) said the PM2.5 concentrations have reached purple levels — concentrations above 71 micrograms per cubic meter, the most severe degree of PM2.5 pollution according to the EPA’s four-color categorization — in Taichung on eight days so far this month, and on 11 days in Kaohsiung.
As the EPA advises the public against outdoor activities when the PM2.5 concentration reaches purple levels, Tsai questioned the education ministry’s standards, as it only suspends outdoor activities when PM2.5 reaches 250 micrograms per cubic meter.
Ministry of Education senior specialist Chiu Jen-chieh (邱仁杰) said the ministry has requested that schools establish an air quality indicator system on campus and that they could decide to halt outdoor activities when PM2.5 pollution reaches purple levels.
DPP Legislator Ho Hsin-chun (何欣純) said the ministry should cooperate with the EPA and the Ministry of Health and Welfare to draft emergency response measures against serious air pollution to safeguard children’s health.
A group of Taiwanese-American and Tibetan-American students at Harvard University on Saturday disrupted Chinese Ambassador to the US Xie Feng’s (謝鋒) speech at the school, accusing him of being responsible for numerous human rights violations. Four students — two Taiwanese Americans and two from Tibet — held up banners inside a conference hall where Xie was delivering a speech at the opening ceremony of the Harvard Kennedy School China Conference 2024. In a video clip provided by the Coalition of Students Resisting the CCP (Chinese Communist Party), Taiwanese-American Cosette Wu (吳亭樺) and Tibetan-American Tsering Yangchen are seen holding banners that together read:
UNAWARE: Many people sit for long hours every day and eat unhealthy foods, putting them at greater risk of developing one of the ‘three highs,’ an expert said More than 30 percent of adults aged 40 or older who underwent a government-funded health exam were unaware they had at least one of the “three highs” — high blood pressure, high blood lipids or high blood sugar, the Health Promotion Administration (HPA) said yesterday. Among adults aged 40 or older who said they did not have any of the “three highs” before taking the health exam, more than 30 percent were found to have at least one of them, Adult Preventive Health Examination Service data from 2022 showed. People with long-term medical conditions such as hypertension or diabetes usually do not
POLICE INVESTIGATING: A man said he quit his job as a nurse at Taipei Tzu Chi Hospital as he had been ‘disgusted’ by the behavior of his colleagues A man yesterday morning wrote online that he had witnessed nurses taking photographs and touching anesthetized patients inappropriately in Taipei Tzu Chi Hospital’s operating theaters. The man surnamed Huang (黃) wrote on the Professional Technology Temple bulletin board that during his six-month stint as a nurse at the hospital, he had seen nurses taking pictures of patients, including of their private parts, after they were anesthetized. Some nurses had also touched patients inappropriately and children were among those photographed, he said. Huang said this “disgusted” him “so much” that “he felt the need to reveal these unethical acts in the operating theater
Heat advisories were in effect for nine administrative regions yesterday afternoon as warm southwesterly winds pushed temperatures above 38°C in parts of southern Taiwan, the Central Weather Administration (CWA) said. As of 3:30pm yesterday, Tainan’s Yujing District (玉井) had recorded the day’s highest temperature of 39.7°C, though the measurement will not be included in Taiwan’s official heat records since Yujing is an automatic rather than manually operated weather station, the CWA said. Highs recorded in other areas were 38.7°C in Kaohsiung’s Neimen District (內門), 38.2°C in Chiayi City and 38.1°C in Pingtung’s Sandimen Township (三地門), CWA data showed. The spell of scorching
