Newly published research from late toxicologist shows dangers of fine particulate matter (2014/03/17)

When one of Taiwan’s best-known public health advocates died last year, he left behind an impressive legacy. Lin Chieh-liang’s contributions continue with new research published by a team he led that shows how fine particulate matter raises the mortality rate of dialysis patients.

These images are of the late renowned toxicologist Lin Chieh-liang. Lin was best known for explaining the intricacies to toxicology-related information to the general public. His influence continues to this day. The research team he led has published new information related to how fine particles smaller than 2.5 micrometers raise the mortality rate of dialysis patients. The work is available in the Public Library of Science.

Air pollution index readings in the TaipeiBasin tend to be higher. The results show that dialysis patients who live in polluted areas have a mortality rate 76 percent higher than patients who live in areas that aren’t polluted.

The study focused on 256 dialysis patients. It found that the relatively high carbon monoxide, nitrogen dioxide, and fine particulate matter in the TaipeiBasin area lead to inflammation. The resulting lowered oxygen content of blood raises the risk of heart attack. This contributes to the higher mortality rate.

Doctors recommend that dialysis patients wear an N95-level particulate respirator when going outdoors. If they feel respiratory tract discomfort, they should see a doctor.

洗腎怕空汙

毒物專家林杰樑醫師他生前所指導的醫療團隊，全球首度證實PM2.5等空污物質，將使洗腎患者死亡率提高七成六，重要的研究成果也登上國際《公共科學圖書館期刊》。

毒物專家林杰樑醫師，一襲白袍專心討論毒物資訊，這身影大家都很熟悉，雖然他過世了，影響力依然存在。他生前所指導的團隊，發現PM2.5等空污物質，將提高洗腎患者死亡率，研究登上國際《公共科學圖書館期刊》。

“住在台北盆地，空氣污染指數比較高，結果看到說，其實住在空氣污染地區的人， 洗腎病患，他死亡率比起沒有污染的地方，高達七成六”

研究針對北部256名洗腎患者，發現由於台北盆地一氧化碳，二氧化氮，以及懸浮微粒PM2.5，濃度比其他地區高出許多，因此會刺激身體發炎，當血液含氧量不足，就會提高心肌梗塞危險性，進而提高洗腎患者死亡率。

醫師建議平時出門，最好養成戴口罩的習慣，尤其洗腎患者，最好帶上醫療級的N95口罩，呼吸道不適時，也要立刻就醫，避免病情惡化。
