    Environmentalists criticize newly adopted air quality standards as too lax (2016/12/19)

    Taiwan’s Environmental Protection Administration adopted a new set of United States air pollution standards on December 1, a move that’s come under fire by environmentalists for relaxing controls on dangerous pollutants. Criticism has focused on the higher air quality warning threshold for PM10, a cancer-causing category of air pollutant that can cause lung and heart problems.

    In the old system, if PM10 reached 150 micrograms per cubic meter a red warning would be issued. But now the red warning threshold in the new US air quality index is set at 255 micrograms per cubic meter, a difference of about 100 micrograms per cubic meter.

    Environmental groups criticized the EPA’s decision to adopt the new AQI pollutant index, which effectively relaxes standards for PM10. The WHO considers PM10 a dangerous carcinogen, and recommends a maximum yearly exposure of no more than three days during which PM10 levels exceed 50 micrograms per cubic meter. However, 76 of Taiwan’s monitoring stations found that PM10 levels exceeded that threshold on more than 200 days in 2015.

    Taiwan has many days during which PM10 is in excess of 50 (micrograms per cubic meter), and actually many days over 60 and even 70 (micrograms). Taiwan’s average yearly PM10 levels are some three to four times the maximum recommended by the WHO.

    (The new system) doesn’t distinguish between pollutants such as ozone, sulfur oxides, and others. But as long as they are air pollutants we will regulate them.

    Some experts suggest the EPA should implement UK air pollution standards, which they argue are stricter than the US standards recently adopted.

    AQI太寬鬆? 環署澄清:按美國標準制定

    環保署12月初採用美國空氣品質指標AQI,遭到環團痛批,標準變寬鬆,以前PM10只要到達150微克立方米,就是紅色警戒, 如今卻要高達255才算紅色警戒,造成民眾混淆,專家表示,PM10是一級致癌物,不只對肺部,甚至連心臟都有影響

    [[台灣健康空氣行動聯盟理事長 葉光芃]]
    “它的PM10以前是150以上就顯示紅色,但新的美國的AQI是255才顯示紅色,差了(100)。”

    環團批評環保署12月1號採用新制AQI後,放寬PM10的標準。PM10是一級致癌物,WHO建議PM10每年最多,只有3天可以超過50微克立方米,但台灣有高達76個站,超標天數高達200天以上。

    [[台灣健康空氣行動聯盟理事長 葉光芃]]
    “台灣很多(測站的年均值)都是50(微克立方米)以上、60以上、70以上,整整超過世界衛生組織的3到4倍。”

    [[環保署環境監測資訊處副處長 張順欽]]
    “不會去區分哪個污染物把它忽視掉,包括臭氧其他的硫氧化物等等,只要這些空氣相關污染物我們都會作管制。”

    環保署目前用的是美國標準,但專家建議台灣環境類似英國,應該採用英國標準。
