38,000 People a Year Die Early Because of Diesel Emissions Testing Failures (theverge.com)
An anonymous reader quotes a report from The Verge: Diesel cars, trucks, and other vehicles in more than 10 countries around the world produce 50 percent more nitrogen oxide emissions than lab tests show, according to a new study. The extra pollution is thought to have contributed to about 38,000 premature deaths in 2015 globally. In the study, published today in Nature, researchers compared emissions from diesel tailpipes on the road with the results of lab tests for nitrogen oxides (NOx). The countries where diesel vehicles were tested are Australia, Brazil, Canada, China, the European Union, India, Japan, Mexico, Russia, South Korea, and the U.S., where more than 80 percent of new diesel vehicle sales occurred in 2015. The researchers found that 5 million more tons of NOx were emitted than the lab-based 9.4 million tons, according to the Associated Press. Nitrogen oxides are released into the air from motor vehicle exhaust or the burning of coal and fossil fuels, producing tiny soot particles and smog. Breathing in all this is linked to heart and lung diseases, including lung cancer, according to the International Council on Clean Transportation, which took part in the research. Governments routinely test new diesel vehicles to check whether they meet pollution limits. The problem is that these tests fail to mimic real-life driving situations, and so they underestimate actual pollution levels. The researchers estimate that the extra pollution is linked to about 38,000 premature deaths worldwide in 2015 -- mostly in the European Union, China, and India. (The U.S. saw an estimated 1,100 deaths from excess NOx.)
Considering that most Americans have less than $10,000 saved, dying early might actually be a good thing.

38,000 out of nearly 8 billion is hardly worth worrying about.
but if those people had such serious breathing problems, weren't they going to die soon anyway? I know when I worked IT for Univ of Washington hospital that most of the people that trouble breathing because of the pollution in Seattle didn't do much better after moving to the middle of nowhere.

It's important to keep in mind that this is only an estimate, expressed as a round number. That doesn't mean that it's wrong, or that we should disregard it, it just means that we shouldn't take it too literally.

And in the same period, how many people died as a result of pollution from ordinary gasoline automotive emissions? Smog is a huge problem in the world but it's not all diesel engines. Removing diesels may help the problem but people are still going to die from health complications because of smog even if everyone just ran gasoline engines. So the deaths are tragic, but at the same time I'm not convinced they are statistically significant as a sole driver of public policy.
Reminds me of the classic scene from Yes Prime Minister where Humphries argues that preventing smoking would just cost the NHS more money and that it's far cheaper for smokers to continue to die at about the present rate. Morally Humphries is wrong of course, but economically he was absolutely correct.
So none then. You propose we sacrifice 10 times that many people banning deisel then?
Time is what keeps everything from happening all at once.

According to a new paper by Ott and Pickering in the Journal of Geophysical Research, each flash of lightning on average in the several mid-latitude and subtropical thunderstorms studied turned 7 kilograms (15.4 pounds) of nitrogen into chemically reactive NOx. "In other words, you could drive a new car across the United States more than 50 times and still produce less than half as much NOx as an average lightning flash," Ott estimated. The results were published July.
When the researchers multiplied the number of lightning strokes worldwide by 7 kilograms, they found that the total amount of NOx produced by lightning per year is 8.6 terragrams, or 8.6 million metric tons. "That's somewhat high compared to previous estimates," said Pickering.
https://en.wikipedia.org/wiki/...
One estimate is that 24,000 people are killed by lightning strikes around the world each year and about 240,000 are injured. Another estimate is that the annual global death toll is 6,000.
love is just extroverted narcissism
Because its not 38,000..
Its 'researchers (who want this to matter) 'estimate' it to be 38,000. Here is how this works.
They take the number of people who die from ANYTHING that can be distantly LINKED to this, and pick a number less than that.
Since this is 'linked' to almost any lung condition..... (not through any actual evidence of course, just because it is 'obvious' - it probably
does have an effect of course, and the magnitude is anyone's guess, because it would be impossible to actually measure..)
In fact the claims are not even correct - NOx is NOT the 'soot' that comes from diesel - the two are almost completely unrelated, and quite different in both effect and risk. this is just an attempt to cash in on 'dieselgate', whos actually effect is to reduce efficiency of diesel engines and actually increase total emissions if actually complied with (because they restrict based on percentage, not absolute output).
Let alone the fact that petrol engines actually routinely produce LARGER total amounts of NOx..
Why you ask? its easy, Diesel is a lot less profitable for suppliers.
Does that make it obvious enough?
Hell, breathing oxygen is 'linked' to 60,000,000+ deaths a year... its not hard to make up stupid numbers..
From dubious statistical extrapolations.
And here we have an idiot as president that wants to encourage burning coal. Yes, soot and air pollution murder people and whether it is from diesel, gasoline or coal it is nothing more than murder. But the right wing goes even further. Once they give a person heart disease or cancer from burning coal they also don't want them to have medical care. They excuse all this nonsense as a monetary issue. But nobody counts the costs associated with heart or lung cripples and the long term disabilities that eat up the national budget. One sick person can run up millions in public expenses.
"It is one thing to present a problem, it is quite another to propose a solution"
Today people present problems, often highly exaggerated , but instead of proposing a solution the only goal is to identify someone to blame for the problem. After blame is assigned they move on to the next outrage of the day.
Smoking causes 7 million premature deaths per year.
Second-hand smoke alone causes 900 000 premature deaths per year.
Not saying emission rules are not important and should not be enforced, but some perspective is important when making rules.
This is why I keep coming back here. There's nothing more entertaining than a good tar and feathering of a bad claim. Keep up the good work guys!
Further, there are multiple oxides of Nitrogen.
Nitric oxide, NO, is used by the body as a regeneration signal. An acquaintance has a job designing NO generators for battlefield use, either as part of an O2 delivery system (to help injured lungs) or to be directly applied to burned skin (to help with regeneration). He's associated with MGH in Boston. They will probably be seeing use in civilian hospitals in a couple of years.
The other oxides dissolve in water to form acids, but NO is actually beneficial.
I wonder if the NOx studies take that into account.
Here is how this works.
You didn't read the paper. I did.
The basic idea in the method is that they ran a number of simulations of where diesel vehicles are estimated to be driving in the 11 jurisdictions (based on real-world measurements), where emissions would end up being carried (and dissipated) by the atmosphere, and matching that up with population estimates. This was then applied to the current best estimates of the exposure-response curves to get an estimate of the number of deaths.
They ran with measured emissions to validate that it matches up with measured death rates. Then they reran with "theoretical" emissions (i.e. if the vehicle emissions actually were what they were supposed to be) and subtracted the two. Actually, they probably ran the simulation multiple times to get a confidence interval; more on this later.
NOx, ozone, and PM2.5 ("soot") were accounted for separately. This is clear from the paper, but not clear from the
The model was validated against real-world studies to make sure that it matched what we find in the field.
Now, if you're thinking that's a lot of assumptions, you're right. The 95% confidence interval is 23,000–47,000, which is quite a wide margin of error. Again, that is not clear from the writeup, but it's clear from the paper.
sub f{($f)=@_;print"$f(q{$f});";}f(q{sub f{($f)=@_;print"$f(q{$f});";}f});
And in the same period, how many people died as a result of pollution from ordinary gasoline automotive emissions?
The question you should be asking is: How accurate are the emissions tests for "ordinary" automobiles?
Because that's what the paper is trying to estimate. Not how many people are killed by vehicle emissions, but how many people are killed by inaccurate vehicle emission testing.
sub f{($f)=@_;print"$f(q{$f});";}f(q{sub f{($f)=@_;print"$f(q{$f});";}f});
It may kill more people, but its politically correct.
Or you could just bring back the (now banned in many places) old diesels that did not make any NOx at all, and put filters on the exhausts to remove the particulates. No, that is NOT politically correct, and won't line the pockets of the AdBlue people.

Sorry to burst the bubble of dishonesty over some activist hack's head, but there's no "there" there.
This is typical statistical garbage rather than real data. Is there a correlation between bad air and people dying from respiratory failure? Almost certainly - HOWEVER there is not a specific direct link in any of those deaths. This is unlike the statisical case against cigarettes. In the case of cigarettes we know the mechanisms, the hows and the whys, and we can pin the names of actual individuals and connect their deaths directly to smoking. In the case of these activist-driven quasi-science stories however we have a different thing: NOBODY can specifically have his/her death pinned on diesel engine exhaust (well, except for people who kill themselves with a hose from the tailpipe of their Mercedes...but that's a different argument about mental health)
This is like those Obama EPA era studies that said farm dust had to be regulated because people were being killed by the dust kicked-up when farmers in places like Kansas plow their fields (a sort-of necessary activity if you do not want the general population to starve to death). Sorry, but if you cannot pin the death of a specific person directly to the specific specified cause, but you are insisting you know how many people are killed by that very same cause, then you are probably doing junk science.
Although here in the U.S., we do have a problem with excessive Vin Diesel emissions.

Wanna help? Don't ditch your diesel vehicle just yet. Diesels are way cleaner than they used to be and continue to get cleaner, Dieselgate notwithstanding. Instead, stop using your fireplace. Not talking about your super-efficient pellet stove with 20 afterburners and particle scrubbers made from unicorn hair, I'm talking about that hole in the wall with the pipe coming out of the roof. Which many people use more for ambience than for heat. Emission of particulates (PM2.5) from fireplaces is close to or even exceeds that of vehicles in several European cities (not countries, which is significant. Local concentration rather than national averages is what matters for effects on our health)

If some publication is going to write about a scientific article, shouldn't they get a journalist with some vague understanding of science to do the writing? Just as an example, this kind of leaps out at the reader:
"Nitrogen oxides are released into the air from motor vehicle exhaust or the burning of coal and fossil fuels, producing tiny soot particles and smog."
Soot is carbon. NOx does not contain carbon, nor can it create carbon. Also, what is the difference between "motor vehicle exhaust" and "burning fossil fuels"?
As far as the scientific article itself is concerned, it seems a bit obvious. Everyone already knows that the testing standards do not reflect real-world driving conditions. If they only find that "more than half" of the light-duty vehicles emit more pollution in real world condition than in testing conditions, that's actually better than I would have expected.
The conclusion: "Adopting and enforcing next-generation standards...could nearly eliminate real-world diesel-related NOx emissions" assumes that such standards are actually achievable. From the cheating scandals, it appears that the current standards are already on the edge - more stringent standards may not be realistic.
Enjoy life! This is not a dress rehearsal.
An emissions test does not have to emulate real world driving conditions; it only has to have a relationship to real world driving conditions and provided a standard baseline to check whether a vehicle is in good repair.

I am a big diesel fan, but your head is up your ass. Diesels ALWAYS generated NOx. ALL of them. Hell, EVERY internal combustion air-breathing engine generates plenty. As long as 4/5 of the atmospheric air they use for combustion is NITROGEN, there is no way in hell you can prevent some of the nitrogen forming oxides.
It's the scent of NO2 that bothers me more than any of the other emissions (yes, I can smell that!). It is a special issue with lean burn engines such as diesels. The problem is that the load levels car manufacturers currently use for passing emissions testing (contrived driving cycles) do not cover some real-world driving scenarios (especially during acceleration), worsened by the fact that some are cheating (we heard about VW). I'm pretty sure many (diesel) vehicles would not manage to stay below the limits set by legislation if tests were performed on average "real" courses using portable measurement equipment (PEMS) instead of doing them on the test bed with synthetic acceleration profiles etc..
It's time to just accept that emissions testing is never going to work right and will always be cheated, so it's just push for zero emission vehicles and move the problem away from population centres to places where it can be more easily controlled and mitigated.

To put it in perspective, there are 6 million deaths per year caused by smoking.
That's one Jewish-part-of-the-holocaust every year.
#1 If you're going to make holocaust comparisons keep in mind where this scandal originated.
#2 The affect on everyone's health are worth considering more than the relative handful that can be more definitively related to this as a cause of death. Diesel cars and Dieselgate is everywhere, it was pretty obvious before the scandal because it stinks, but we've been breathing that shit in as pedestrians for decades... i'm a young healthy individual, but it will definitely have damaged my lungs, I can't quantify it but in the future I will have decreased lung capacity, I may be less active depending on the significance, it will also have increased my chances of lung cancer... even though I don't smoke. I didn't ask for this, Diesel fumes are the only significant source of NOx in this country.
Upside? Car wrecks are self-cleaning.
Asphalt is flammable.
The generating plants are more-efficient, such that a certain lump amount of fuel burned provides more miles driven. It's not one oil plant per car--that would just be a car with a diesel engine.

It's time to just accept that emissions testing is never going to work right and will always be cheated,
As I read the article (not having read the referred-to paper):
This wasn't about cheating. This was about the government-prescribed test cycles not correctly modelling the actual average driving cycle of the world's fleet of vehicles, the academic's model of the actual fleet emissions being somewhat off, the error happening to be on the low side, and recent measurements updating the model.
The mandated emissions testing cycle was KNOWN FROM THE START to be only roughly representative of overall vehicle usage. (That's why "your mileage may vary". Though on-the-road emissions are hard to measure, mileage is easy, and mileage during the test cycle falls out of a simple calculation of carbon emission as CO, CO2, unburned hydrocarbons, and exhaust volume. And it is - that's where sticker mileage comes from. When they systematically mismatch you know the test cycle mismatches average usage.)
And this was FINE. As long as the testing was REPEATABLE, ROUGHLY PROPORTIONAL to the actual cycle emissions, and covered all the common driving modes, it was an effective tool to drive emission-reduction engineering and legislation. The engineering might tend to improve the test results slightly more than fleet average (because that's where the selection pressure of the evolutionary algorithm happens to be). But it still drove a DRASTIC than fleet average (because that's where the selection pressure drop in emissions and a resulting drastic, and measurable, improvement in air quality.
Cheating consists of having the engine control recognize whether the vehicle is running the test cycle and changing its behavior - being good on emissions during the test, bad on emissions but better on performance and/or mileage when not on the test.
Voice of experience here: I wrote emissions analysis and engine control software for two of the Big Three during the 70s and 80s.
We all knew that it would be possible to write cheats into the code. And we all knew not to do it - because it would not only be bad for the environment, but it would also eventually be caught, and cause the company massive trouble. So the engineers were very careful not to do it, the managers were careful not to give the engineers an incentive to do it, and upper management put in drastic organizational controls to both prevent and detect it.
Fast forward a couple generations of executives and you find:
- A German automaker with executives who decided that cheating was the way to go.

Fast forward a couple generations of executives and you find:
- A German automaker with executives who decided that cheating was the way to go, and actually detected whether there was a driver (e.g. steering wheel moving) and did the same cycle differently.
- An American automaker (the former big-three company I didn't work for back in the day, now owned by an Italian automaker) accused of cheating because they didn't do as well in some extreme conditions outside the testing regime as they did within it, and have a difference of opinion vs. the regulators on what some of the law means.
The first is cheating. The second is up for debate (and being debated in the legal system). But neither is what this "Testing Failure" article was about.

Do smokers really die early on average? It seems like every one that I've known kept hacking and wheezing miserably to a ripe old age, ultimately costing the health care system more in the long run.
Yes, they do.
It's sampling bias: You just happen to know a bunch of old, hacking, smokers because they're the ones that didn't die off yet - while the young ones mostly aren't yet to the hacking stage.

Especially when you get to Stalin. That guy was totally a killer. I name Stalin and while I think your "wanted to" isn't appropriate, Stalin lets me play with that handicap. He wanted to kill people. When Russ Hanneman met Stalin, he was all, "This guy kills! Am I right?"

Stop the lightning.
Reducing emissions like NOx makes sense in places like the Los Angeles basin where there is reduced air circulation and concentrated population centers. But it literally makes no sense in other areas where CO and HC emissions need to be targeted, even at the expense of some more NOx.
When I search for articles about NOx, I find information about the nitrogen cycle and how plants depend, in part, on the NOx produced in the atmosphere by lightning. So, it's plant food.

No one died. In order to get to this number, the researchers had to tap dance with numbers and forget to consult with wmbriggs.com
Doing that might have reduced the chance of their next paycheck though.
God: "I don't leave footprints!"
We mention that specifically in the paper (I'm a co-author). In Europe, the human health impact of the excess diesel NOx emissions is estimated to be 1/4th that of the total impact of all land-transportation sources of pollution (as estimated in Silva et al., Environ. Health Perspect., 2016). I think that's a pretty significant portion of the problem to be coming just from this particular source!
There is ample evidence from several tests in multiple countries to suggest that very few current diesel cars meet NOx emission limits even if they perform the exact same test run on the street in non-laboratory conditions. Even fewer come close to emission limits when driven in more realistic patterns.
Exactly.
It's interesting that NOx is so apparent to you. I don't think I've ever knowingly smelt it.
I'm not sure whether I've been sensitized for the smell of NO2 because we had to synthesize it during a lab course (we condensed it into a glass tube and sealed that by melting). Later I would also supervise those lab courses several times. Every once in a while, the sealed tubes of some students would not withstand the pressure upon dewing and explode, after which the awful smell of NO2 was quite pronounced. To be clear, I don't like the smell of other engine emissions either (and of course, unburnt fuel stemming from mopeds is among them). The runner-up to NO2, for me, would be the 'sooty' kind of smell.
