Fine particulate matter smaller than 2.5 micrometers (PM2.5) and PM10 could cause infant deformities and lung cancer, environmental group Air Clean Taiwan said on Thursday, reiterating a call to tighten air pollution monitoring standards.
There are no safe levels for PM2.5, as many studies have suggested that the particles might penetrate the placenta, organs and cells, and damage human health, Air Clean Taiwan chairman Yeh Guang-perng (葉光芃) said.
However, the Environmental Protection Administration (EPA), in its draft amendments to air quality standards, released in May last year, did not adjust its monitoring standards for PM2.5, Yeh said.

The agency’s maximum acceptable concentration level for PM2.5 is 15 micrograms per cubic meter per year and 35 micrograms per cubic meter in a 24-hour period, he said.
Canada’s annual average PM2.5 level is 6.1 micrograms per cubic meter, and it has linked more than 14,600 premature deaths each year to air pollution, Yeh said, asking how Taiwan’s relatively loose standards would not have a greater impact.
The EPA should tighten PM2.5 monitoring to 10 micrograms per cubic meter per year to match the WHO’s standards, or the US’ 12 micrograms per cubic meter, which might prevent an estimated 3,568 premature deaths, he said.
Exposure to PM10 might cause fetus deformities, autism, kidney dysfunction or stroke, New Taipei City Clinics with Health Insurance Association chairman Wang Huo-chin (王火金) said.
PM10 exposure could also increase a person’s risk of lung cancer or dementia, Taipei Medical University Hospital physician Chen Ching-hui (陳菁徽) said.
EPA Department of Air Quality Protection and Noise Control Deputy Director-General Hsu Su-chih (徐淑芷) said the agency would publish a final draft of the amendments to air quality standards by the end of this year, as it is required by the Air Pollution Control Act (空氣污染防制法) to review the standards every four years.
The EPA is tasked with protecting people’s health, but it is cautious in adjusting the standards, as any changes might affect many parties, Hsu added.
LOUD AND PROUD Taiwan might have taken a drubbing against Australia and Japan, but you might not know it from the enthusiasm and numbers of the fans Taiwan might not be expected to win the World Baseball Classic (WBC) but their fans are making their presence felt in Tokyo, with tens of thousands decked out in the team’s blue, blowing horns and singing songs. Taiwanese fans have packed out the Tokyo Dome for all three of their games so far and even threatened to drown out home team supporters when their team played Japan on Friday. They blew trumpets, chanted for their favorite players and had their own cheerleading squad who dance on a stage during the game. The team struggled to match that exuberance on the field, with
Taiwanese paleontologists have discovered fossil evidence that pythons up to 4m long inhabited Taiwan during the Pleistocene epoch, reporting their findings in the international scientific journal Historical Biology. National Taiwan University (NTU) Institute of Ecology and Evolutionary Biology associate professor Tsai Cheng-hsiu (蔡政修) led the team that discovered the largest snake fossil ever found in Taiwan. The single trunk vertebra was discovered in Tainan at the Chiting Formation, dated to between 400,000 and 800,000 years ago in the Middle Pleistocene, the paper said. The area also produced Taiwan’s first avian fossil, as well as crocodile, mammoth, saber-toothed cat and rhinoceros fossils, it said. Discoveries

Whether Japan would help defend Taiwan in case of a cross-strait conflict would depend on the US and the extent to which Japan would be allowed to act under the US-Japan Security Treaty, former Japanese minister of defense Satoshi Morimoto said. As China has not given up on the idea of invading Taiwan by force, to what extent Japan could support US military action would hinge on Washington’s intention and its negotiation with Tokyo, Morimoto said in an interview with the Liberty Times (sister paper of the Taipei Times) yesterday. There has to be sufficient mutual recognition of how Japan could provide
