基本上，
大部份的研究資料都來自於財大氣粗的廠商，
各國鮮少能夠有主管單位或獨立單位，
對這些主題進行樣本數夠大的研究。
所以，
當廠商無良，
受害的是消費者～
等到累積足夠的官方或民間研究，
讓官方單位下重手時，
往往，已經有許多人在過程中受害了。
最近的一例，
就是「反式脂肪」這個東西：
https://zh.wikipedia.org/wiki/%E5%8F%8D%E5%BC%8F%E8%84%82%E8%82%AA
剛被研發的「數十年」，簡直是神物，
現在，卻成了文明國家人人喊打的過街老鼠。
而這數十年，卻透過心血管、腦血管疾病，
造就了數百萬「人年」的損失。
愛自己和家人，
就別再迷戀柴油動力的省油、高扭力了～
有東西，是比省錢、和自爽，
要來得更重要的！
包括，你和家人的健康。

按一些版友的立論，
用在下列主題，大概會是這般觀點：
(1)「反式脂肪」不好，
所以「所有脂肪」都不好、都不要吃!
但，您可知，「所有脂肪(包括飽和脂肪和不飽和脂肪)」，
是身體組織的重要元素，
都不吃，反而更是百病叢生。
(2)「吃紅肉」不好，
所以「所有動物蛋白質」都不好、都不要吃！
但，您可知，吃全素的人，
很容易缺乏某些關鍵營養素，包括維他命B12，
以致，腦力反而不足。
(3)「柴油車」不好，
所以「所有的機動車輛」都不好、都不要用！
但，您可活在馬車時代？
而，即便開馬車，您可知道，
馬也要吃草、和牛也一樣會排甲烷，
以致，造成溫室效應。
那麼，騎單車呢？
單車的路上事故率，
僅次於機車，
更何況，
不是每個人都可以騎單車上武嶺賞櫻的～
「過猶不及」、「中庸之道」，
以及「兩害相權取其輕，兩利相衡取其重」，
才是我們該有的準則，您說是嗎？

氮氧化物確定為非致...(恕刪)
中文維基查氮氧化物清楚標明為"空氣汙染物"
查英文的維基寫得更清楚
就是有毒物質
會導致呼吸系統疾病及加重心臟疾病 也是酸雨來源
會不會致癌我不知道 但絕對危害健康
有空多查查看吧
NOx
Environmental effects
NOx reacts with ammonia, moisture, and other compounds to form nitric acid vapor and related particles. Small particles can penetrate deeply into sensitive lung tissue and damage it, causing premature death in extreme cases. Inhalation of such particles may cause or worsen respiratory diseases, such as emphysema or bronchitis, or may also aggravate existing heart disease.
NOx reacts with volatile organic compounds in the presence of sunlight to form ozone. Ozone can cause adverse effects such as damage to lung tissue and reduction in lung function mostly in susceptible populations (children, elderly, asthmatics). Ozone can be transported by wind currents and cause health impacts far from the original sources. The American Lung Association estimates that nearly 50 percent of United States inhabitants live in counties that are not in ozone compliance.
NOx also readily reacts with common organic chemicals, and even ozone, to form a wide variety of toxic products: nitroarenes, nitrosamines and also the nitrate radical some of which may cause biological mutations. Recently another pathway, via NOx, to ozone has been found that predominantly occurs in coastal areas via formation of nitryl chloride when NOx comes into contact with salt mist.
NOx emissions also causes global cooling through the formation of OH groups that destroy methane molecules, countering the effect of greenhouse gases. The effect can be significant. For instance, according to the OECD "the large NOx emissions from ship traffic lead to significant increases in hydroxyl (OH), which is the major oxidant in the lower atmosphere. Since reaction with OH is a major way of removing methane from the atmosphere, ship emissions decrease methane concentrations. (Reductions in methane lifetimes due to shipping-based NOx emissions vary between 1.5% and 5% in different calculations)." "In summary, most studies so far indicate that ship emissions actually lead to a net global cooling. This net global cooling effect is not being experienced in other transport sectors. However, it should be stressed that the uncertainties with this conclusion are large, in particular for indirect effects, and global temperature is only a first measure of the extent of climate change in any event."
