Re: [新聞] 世衛專家證實 柴油廢氣導致肺癌

實在看不下去了

記者真的太亂來......

所以我去找了報告書原文
http://press.iarc.fr/pr213_E.pdf

人家明明寫的很清楚:
Increasing environmental concerns over the past two decades have resulted
in regulatory action in North America, Europe and elsewhere with
successively tighter emission standards for both diesel and gasoline
engines.

There is a strong interplay between standards and technology – standards
drive technology and new technology enables more stringent standards.
For diesel engines, this required changes in the fuel such as marked
decreases in sulfur content, changes in engine design to burn diesel fuel
more efficiently and reductions in emissions through exhaust control
technology.

However, while the amount of particulates and chemicals are reduced with
these changes, it is not yet clear how the quantitative and qualitative
changes may translate into altered health effects; research into
this question is needed. In addition, existing fuels and vehicles without
these modifications will take many years to be replaced, particularly in
less developed countries, where regulatory measures are  currently
also less stringent. It is notable that many parts of the developing
world lack regulatory standards, and data on the occurrence and impact of
diesel exhaust are limited.

也就是說，目前新的柴油引擎設計上已經被要求提高運轉效率並改善汙染排放，
同時也有對柴油有含硫量的限制。
考慮了這些改善因素後，這個問題還有需要進一步討論。
