WHO已經確定柴油車...(恕刪)
我們公司本身是做引擎尾氣排放的量測設備商,其實柴油車所安裝的過濾器是比較針對大顆粒的微粒子(>5um),至於小顆粒(<2.5um)的部分,阻擋效果有限,更不用提那些早期的柴油車,連過濾器都沒有,但是俗稱的PM2.5基本上是會對人體造成很多負面的影響,因為它不容易排出體外,如果微粒子表面沾黏了許多致癌物質,進入人體的話......各位可想而知,所以歐盟的柴油引擎排放標準才會提升至EURO6,是要控管柴油車所排放的PM2.5的量(台灣不知道何時會實施?),當然並不是汽油引擎的車輛不會排放,只是相對的柴油車比較嚴重,另外樓上大大有提到戴口罩是否可以阻隔這些致癌微粒?很抱歉告訴各位,是不行的,活性碳也只能讓你聞到時比較不會那麼臭而已,真的要阻隔,應該也只有N95等級的口罩,但是戴起來不能有洩漏喔,不然也是一樣....(話說騎車時戴N95,除了呼吸困難外,也很好笑捏~)

說實在,小弟潛水很久了,實在對這種無聊的議題沒興趣(反正台灣記者發新聞的篩選程度如何民眾最知)
但是若是竟敢發"油電車掃盲的"maken大來自暴那就讓他打臉吧
請maken大大回應一下WHO的下面文字(敢問maken大認不認識Limited evidence of carcinogenicity這幾個英文字?)至於WHO引用的學術論文統計母體就先暫時略過，以免maken大下不了台
Group 4: The agent is probably not carcinogenic to humans.(恕刪)
1.我知道「limited evidence of carcinogenicity」的意思。然後呢？
2.不管是世衛官網的簡單報導或是全文，都很明確地把柴引廢氣列為group 1。
『After a week-long meeting of international experts, the International
Agency for Research on Cancer (IARC), which is part of the World Health Organization (WHO), today classified diesel engine exhaust as carcinogenic to humans (Group 1), based on sufficient evidence that exposure is associated with an increased risk for lung cancer.』
『The scientific evidence was reviewed thoroughly by the Working Group and overall it was concluded that there was sufficient evidence in humans for the carcinogenicity of diesel exhaust. The Working Group found that diesel exhaust is a cause of lung cancer (sufficient evidence) and also noted a positive association (limited evidence) with an increased risk of bladder cancer (Group 1).』
『Large populations are exposed to diesel exhaust in everyday life, whether through their occupation or through the ambient air. People are exposed not only to motor vehicle exhausts but also to exhausts from other diesel engines, including from other modes of transport (e.g. diesel trains and ships) and from power generators.』
『Dr Christopher Portier, Chairman of the IARC working Group, stated that “The scientific evidence was compelling and the Working Group’s conclusion was unanimous: diesel engine exhaust causes lung cancer in humans.” Dr Portier continued: “Given the additional health impacts from diesel particulates, exposure to this mixture of chemicals should be reduced worldwide.“』
而group 1的意思，按照WHO同一篇的附錄，是
『 The agent is carcinogenic to humans.
This category is used when there is sufficient evidence of carcinogenicity in humans. Exceptionally, an agent may be placed in this category when evidence of carcinogenicity in humans is less than sufficient but there is sufficient evidence of carcinogenicity in experimental animals and strong evidence in exposed humans that the agent acts through a relevant mechanism of carcinogenicity.』
我才想請教你一聲，這和閣下抬出來的group 4何干？請說明。就算不是這一則WHO的新結論吧，1988年，IARC就已經把柴引廢氣的致癌等級列為比汽油引擎廢氣更高的group 2a了。閣下這位一心想打我臉的，引出個和它離得很遠的group 4，其中原委為何，真是讓我費解。
有辦法「讓我下不了台」的話，儘管出手。橫豎我也只是把WHO的東西轉貼出來而已，你要質疑WHO的說法儘管去。連WHO白紙黑字寫明group 1、sufficient evidence都能不知何故沒看見或者沒看懂了，這種程度想給我打臉，在擔心會不會讓我下不了台之前，先擔心你自己吧。潛水多時難得浮出來發言，一發言找人尋釁卻這麼破綻百出拙劣不堪。很有趣啊！
很多人口口聲聲說柴引廢氣致癌的消息是台灣記者亂擬的稿子，所以我請大家直接看WHO官網的內容。就這麼簡單。
