Diesel exhaust.

Some on YT hate the EPA wanting cleaner air.

I can't inhale diesel exhaust without getting a throbbing headache in 15 second. If a diesel truck passes me, I have to pull off, until the air is free of exhaust.

I found an interesting article about diesel exhaust. Bet someone on TY will say it's not true. Like tobacco said 40 years ago smoking won't kill you. So, if this article is wrong, please post a link showing diesel exhaust is safe.

Cancer
Vehicles emit numerous carcinogenic chemicals. Diesel contains benzene, formaldehyde, and 1,3-butadiene?all three are well recognized carcinogens. EPA estimates that vehicle emissions account for as many as half of all cancers attributed to outdoor air pollution.

Please if you have a diesel, do your best to maintain the air pollution devices the EPA requires.

I'm hoping someday to buy my bucket list tractor, new gas tractor.

Is there anyone else that has difficulty breathing diesel exhaust? Do you know anyone with lung cancer?

I also realize that diesel tractors are necessary, no way do I want a total ban on diesel engines. I just want to stay away from them. Don't really want lung cancer either.

I have worked in health care for over 37 years. And I can tell you that there are more things that can cause cancer than you can shake a stick at. Diesel exhaust may very well be one of them. That new carpet smell in a new car or home is another. Heck they even say now that meat cooked over charcoal is bad for you. I work on people with lung cancer almost every day. And its almost 100% they have had exposure of being a smoker or living with a smoker. There are some exceptions but not that often. Smoking you can avoid. A diesel truck going by is much harder to avoid and much less a danger. I wouldn?t want to suck in exhaust 10 hours a day right down my throat like a smoker does. I'm sure that wouldn?t be good for you. I have been at some tractor pulls that if the wind is from the wrong direction it will give me a dull head ache.
 
Isn't formaldehyde in carpet, the trailers sold to FEMA after Katrina, and the glue used to make laminate flooring sold by lumber liquidators in China?
 
Has this always bothered you ? or is it more recent ? I never minded diesel exhaust from a good running one before but recently with the advent of low sulfur and maybe more likely DEF I really hate the smell of some of these and it really bothers me too. If I get behind one of them in my car it sucks that nasty fumes right into it and makes me sick too.
 
My dad was a diesel mechanic for most of his life. They hardly ever put the exhaust tubes out of the ceiling on the trucks in the Plough Inc. garage. And right down the street was Vesocal Chemical and Humko plants. It always stunk around there and Humkho had to repaint a lot of trucks and cars where the chemicals in the air fell on them and messed up the paint. Daddy was always clearing his throat and later in life had breathing problems. I used to work at Payless Cashways part time and the cheap paneling had warning labels on the back that said contains formalgihyde (Forgive the spelling) and said do not use around children and people with respitory problems. I'd show that to people when they wanted to buy it but it was cheap and they never cared they got it anyway.

Geo: Thing of it is is "they say". We have proof beyond any question that smoking cause cancer. As far a diesel we have the EPA saying. Too many people were around heavy diesel smoke for too long without getting cancer for me to believe that. If that were true, non smoking diesel techs from before the day of shop exhaust fans and heavy equipment operators would all be dead or dying of cancer at the same rate as smokers or at higher rates. The EPA would like to outlaw ALL internal combustion engines. I believe that they are doing the old "camels nose under the tent flap" thing. Go after one, the less used one then go after the rest. From what I was told tierIII diesel is cleaner burning than a modern gas engine. If that's the case why did they force through the tierIV if they were not trying to kill the diesel? I understand that it has a bad effect on you. Well tell you what, go out to your garage and close the doors. Then start your car. See how long you last. Then do the same with a diesel. Diesel fuel combustion engines produce much lower concentrations of carbon monoxide (CO) than gasoline engines. That gas engine you love so much will kill you much faster!

I believe that it is like "eggs are bad for you" bacon is bad for you" diesel exhaust is bad for you" " . Excessive amounts MAY be bad but the occasional breath of diesel exhaust won't cause cancer or else we would all be dying from it. There is no doubt that asbestos causes lung cancer and other problems. However the people that developed these problems worked with asbestos for YEARS, not just an occasional exposure. Typically we only get the fear mongering part of the story, not all the facts.
 
I would imagine these same chemicals are in most hydrocarbon fuels in varying degrees. Don't let the boys at the coffee shop get you all riled up. If diesel bothers you, I am sorry. Others mileage may vary. Mike
 
Mike diesel didn't bother me driving tractors on farm as a kid. Worked at Bethlehem steel for a few years. Air was so bad it was like I smoked 2 backs a day. I never smoked. Past 40 years I react to diesel, two cycle, even someone smoking, headache in less than 15 seconds.
 
I can't breathe diesel either. I quit one job because they run diesel in a cylinder heater in winter. I could have stood kerosene but not diesel.
 
Danny, was it Velsicol you were referring to? Such as the one in St Louis, MI that destroyed the Pine River? Or not that one?
 
I was always told formaldehyde was a naturally occurring chemical in all wood products. How old are you and what did you for a living and what kind of shape are you in?
 
Bingo, Greg.

Everything is bad for you.

Getting up in the morning is risky.

Not to worry. The nanny state will eliminate all risks for all of us.

I predicted some would say diesel exhaust doesn't cause cancer and some even say the EPA just made it up. Read the articles from WebMD and Mayo Clinic. This isn't coffee shop hyp it's real.

From WebMD:
Diesel engine exhaust does cause cancer
The International Agency for Research on Cancer has re-classified diesel engine fumes as carcinogenic to humans.


Here is what Mayo Clinic has to say;

Before this June, 2012, diesel engine exhaust was listed as a 'possible carcinogen.' Now the World Health Organization has classified the fumes as cancer causing. As semis roll down the road, there's a new threat level when it comes to their emissions?Health experts say diesel engine exhaust is now in the same carcinogenic category as asbestos, benzene and tobacco smoke. "The studies seem to suggest that there's an increased risk of lung cancer, and possibly bladder cancer," said Stephen Campbell, M.D. of Mayo Clinic Health System.

http://inthenews.mayoclinic.org/?s=diesel+exhaust

I know 2 truckers with stage 4 lung cancer. One trucker is only 52 and never smoked. The other quit smoking 10 years before his cancer. Can't really say they got cancer for diesel exhaust. But the 52 year old man has no doubt it did.

Perhaps you will change your mind when you get lung cancer and never smoked.

If I may add something here....
Older diesels had a kind of "kerosene" smell to them when idling. More of a "furnace" smell to them under load. At least that is what they smelled like to me.
Somewhere along the line, they added some type of exhaust device to them that I am told was some form of a catalytic converter. These were the ones that had to periodically regenerate. Their exhaust had a really sour smell to them. Those would give anybody a headache in no time flat.
However, the newer ones - tier IV I suspect - seem to have no smell to them at all.

Back in the 1980s, when we were emission testing cars (gasoline powered) with a probe in the tailpipe, emissions were quite low. Something like 200ppm or less on the HCs and around 10ppm or less on the CO. Even then, diesels were considered cleaner than gas because they emitted much less HC and CO. Their downfall was particulates and NOx emissions. This was due to the lean running nature of diesels along with higher combustion temperatures. Now, diesels are coming with particulate filters, catalysts, and EGR. By now, there should be nothing coming out of the exhaust but fresh air.

If you want to know what REALLY stinks, get behind an older car prior to 1975. Those fumes will bring tears to your eyes.
 
If all this stuff causes cancer then explain to me how a baby can be born with it? Diesel trucks now emit less pollution than exists in most major US cities. yes they are cleaning the air. They have particle filters in the exhaust and use def. to clean the filters and burn off pollutants. Cancer has been around forever they used to call it consumption.
 
With the exception of the Allis B that I mow with, all of my tractors and trucks are diesel. Wouldn't have it any other way. I mentioned this here a month or so ago that one night I went up to the fuel station for something, and there was an absolutely gorgeous Mack R being fueled up. Lots of chrome and polish, sleeper, twin screw, accent lighting everywhere without being gaudy looking lined in front of its grain trailer. That was one of the sharpest I've ever seen. Just beautiful so I complimented the farmer that it belonged to. He smiled, beaming from ear to ear and repeated a couple of times, "She sure blows smoke". I bet she does and am darn glad for the fella. Truth be told, I wish she was mine cause I'd be proud of the smoke I'm sure that she blows. Darn proud.

I have a lot of aches and pains from different things that we were around and worked with. Some of the things we did were damaging to our bodies. I did not have to do any of this, I could have worked else where. Time has shown that there are hazards everywhere and we learn to live with them. Some people think they got a s deal in life and want to p and moan about it all the time. If it makes you feel better good on ya. There are a lot of things I would like to be able to buy new today that are not out there anymore, no market no product. I can see wanting a new gas tractor, narrow front and cab, not going to happen. A lot of things in life are not fair unloading your unhappy put upon life on the rest of the world will not make your life any better. I am sorry for the problems you have, and I do mean that. May be time to look around you and see what real trouble's are and consider just how lucky you are to be able to do what you do.
 
Fun fact, even with DPF technology, diesel engines still emit PM but a fair amount of this PM is made up of very small particles. It just so happens that modern gasoline engines also emit PM with particles in this size range during transients. It has recently been found that the smaller particles are more likely to cause cancer due to how far they can work their way into your bronchial tubes. The larger particles ( like the black stuff that you see as smoke) is not as harmful.
 
Well george, You could be pulling out of your gravel yard and get TEE Boned buy a dump truck. Do you quit going to your gravel yard, or mount a protest to stop all dumptrucks from travling on the road to your gravel pit.
Life is at risk from the time you get up in the morning until you go to bed!!! And then you may die in your sleep.
I just try to be causious and hope for the best. You can't change everything to your own likeings.
Loren
 
You are wrong. I have an old gravel pit, but it hasn't been operational in 50 years. It a relational like park, our private shootings range. One large flower bed. NEVER sold gravel but do use for my own purposes.
 
Look under your kitchen sink if you want to find something that will cause cancer. Almost all cleaning products, aerosol air fresheners and even dryer softener sheets can cause cancer. Ever read the warnings on a tube of tooth paste? If you swallow to much of it you are advised to contact the Poison Control Center. The list goes on.
 
Wait George....you shoot guns at a range? Are you concerned about the chemicals that burning gunpowder ejects into our atmosphere? I am sure that algore would tell you that it contributes to global warming!!!
 
stonerock,
Wrong to say I'm a city boy. Lived in the city 3 semesters during college, grew up on a dairy farm, country boy all my life.

I find some people on YT to be like big tobacco 40 years, in denial. No scientific proof smoking causes cancer, No proof tobacco killed the Marlboro Man and John Wayne. They would have gotten cancer without smoking. No proof diesel exhaust causes lung cancer. It's cool to attack the messenger on YT, calling me a city boy. So childish. Name calling is a form of bullying. Seems to be a lot of that going around on YT too, not to mention in politics.

I'm glad my state has laws against smoking in public places. I enjoy eating and not breathing second hand smoke.

I'm glad the EPA is looking after the air I have to breath. I enjoy breathing clean air.

And I looking forward to the day when I can buy a new 30 hp gas powered tractor. I may not get my narrow front end, but I will be smiling ear to ear in a climate controlled cab.

I also hope none and pray none of you get lung cancer.

My wife is the same way....She is highly allergic to lots of petroleum products....Smelling diesel fuel and fumes makes her ill....That presents a problem since I have several diesel tractors..She didn't used to be that way when she was younger..
 
George, I have no doubt that diesel exhaust gives you headaches. You probably are allergic to it, or have some reaction to it that most people don't have. Fumes from a kerosene space heater affect me that way and they don't bother most people. Scientists will tell you that a lot of things cause cancer, mainly because they don't know exactly what causes cancer. Science in general is not an "exact science". Something that was absolute scientific truth one day, will be proven totally false after further review. Because of that, I have to use my own experience and common sense to decide if something is bad for me. I know or know of many people that smoked, that have lung cancer or related diseases, so I believe that smoking causes cancer. I was born into a farming family and I operated and repaired heavy equipment all of my life, so I have known many people who have done the same. I don't know a single person that operated or repaired diesel equipment that has lung cancer, that didn't smoke. I have to conclude that the chances of getting cancer from diesel exhaust is very small.
 
Diesel exhaust bothers me too. Not headaches and all but after a couple hours on a diesel tractor I feel queasy. I run mostly propane tractors.

I swear diesel exhaust smelled different 25 or 30 years ago. Now it smells like someone blew out 100 candles all at once, kind of a burning wax smell.
 
My wife (who grew up on a farm) is sensitive to the smell of petroleum products like Kerosene and diesel fuel, and diesel exhaust. Sometimes her throat closes up to the point of needing her Epipen in order to breathe.
 
I really can't get going til I've breathed in several good huffs of diesel exhaust. Don't know why but it has always invigorated me for the past 40 yrs.
 
Genetics has as much to do with how your body reacts to certain chemicals as anything. You get headaches from diesel but I get headaches from women's perfume. I literally can't breath if I just get a whiff. Diesel doesn't bother me at all and I've been breathing it for over 40 years.
My grandfather was a chain smoker, he smoked filterless Camel cigarettes and the only time he didn't have one in his mouth was when he was spitting his Days work tobacco juice. He lived to be 87 and died from complications of gallbladder surgery.
My point is that the "experts" are always moving the goal post. They do a study and call it fact. If they had done a study on people like my grandfather they would have concluded that tobacco was healthy.
 
You need to get a team of Mules seems like they'd be the perfect match for you,do your tillage work and then they'd do your weed eating on their day off.Plus you would have something
to talk to when you felt the need.
 
I know of secretaries that never smoked and died from lung cancer. Perhaps the office copier was diesel powered.
 
I think genetics really determine how long you live and what you die from. Weak genetics wont tolerate much exposure to certain chemicals before you succumb when strong genetics will allow you to accumulate a lot of toxins in your body. The headaches are probably a symptom of the accumulation of a lot of the chemicals that you have stored in your body and your body is saying that it can not accept much more. It would probably be best for you to limit your exposer to these chemicals that cause you discomfort for your own good.

I worked for years with a guy that painted large industrial parts with epoxy paints. no respirator. The guy smoked like a Fein, always had a coffee in his hand and his lunch came from the vending machine. At the end of the day he would dip his finger in the paint thinner then run it up his nostrils to clean the paint residue from his nose. He is still alive in his early eighties. I would have bet that he would have died way before retirement but he is still going.
 
Pair-a-dice

Genetics has as much to do with how your body reacts to certain chemicals as anything. You get headaches from diesel but I get headaches from women's perfume. I literally can't breath if I just get a whiff.

I can't stand women's perfumes, other organic smells.

Diesel exhaust still tips my list. This all started from me wanting a 30 hp new gas tractor and no one makes one in the US.

My Aunt smoked all her life too, right up to the time the died from lung cancer.
 
I'm the same way. I can't stand portable K1 heaters and torpedo heaters. Not a lot of difference between K1 and #2 diesel exhaust, both give me a headache.
 
You need to meet my 71 year old brother. After farming he was a heavy equipment operator for 30 years. Dr say he has only 25% lung capacity. Dr asked him if he was a coal miner?

Other brother sucked on a nebulizer 6 times a day before he died, lung issues.

Dr's have no idea where the 100's of black spots in my lungs came from, not to mention the golf ball tumor. Glad I don't have lung cancer. Glad I never smoked. I do everything I can to protect my lungs. I have respirators, charcoal filters and all, on my tractors, mowers and one in the truck. I hate wearing them, but really no choice until I get a tractor with a climate controlled cab.

Everyone can find a person who smoked all their life and died from something else. Doesn't mean smoking isn't a leading cause for lung cancer. Research will someday show diesel may be leading cause. Particles from coal fired power stations may surpass all the rest.

Times are changing, thanks to the medical research and the EPA acting on that information.
 
I'm going to fully admit I did not read that entire 60+ page paper but one thing that immediately jumps out.

The paper is dated 2006. that was before any type of stricter emissions went onto vehicles.

most of the research they cite is from the 90s, with little from the early 2000s.

I don't even think ULSD was standard in 2006 yet.

so my diesel truck causes cancer? guess what, according to the state of California, so does the charging cord for my iphone.
 
If diesel does I should have all types of cancer, I hauled millions of gallons of the stuff. If I got a bad cut I would poor some diesel on that and it would be healed up the next day. I've been soaked so many times I cant count them. I grew up running gas tractors and I have 1 now that hasn't been run in 10 years, my preference is diesel, wide fronts. they ride better that narrow fronts, you don't have front end balling up with mud after every rain and the advantages go on and on.
 

It probably will be better for you in the rest home, maybe you should go there now. Be sure to pick one that doesn't smell of old urine and Pine Sol - you never know what that odor will cause!
 
I can avoid sawdust too, especially fine oak, but I can't avoid diesel trucks polluting the air when I'm driving.
I elect to stay away from diesel tractors, because of headaches and it feels like an elephant is sitting on my chest.
I won't allow anyone to smoke in my shop, house or car. Extremely glad Indiana has a no smoking law, smoke free public places.
I guess the guys at YT are smarter and know more than the Dr's at Mayo Clinic that say diesel exhaust causes cancer. Sure can't defend that argument.

Carcinogens not only cause lung cancer, it can cause other forms of cancer too.

I read some place fatty organs are humans toxic waste dump, liver, pancreas, brain.

Take lead in little kids. It attaches to brain cells and causes learning disabilities. A chemist got exposed to mercury, she had all sorts of brain issues.

I elect to limit my exposure to carcinogens. You may do what you want.

Again, I hope the EPA pushes for stricter standards concerning all forms of air pollution. I'm all for cleaner air.

Hope I live long enough to buy a new gas tractor.
 

Some people just get an idea or conditioned to believe that something is hazardous and then the oder is somehow worse than it is to somebody that doesn't find the item hazardous . Similar to the fish diner that smells good to the cook but stinks other people out of the house.
Diesel has hardly stunk since ULSD was introduced.
The same environmental protestors screaming about coal and carrying images of 1940's smoke stacks . as they march outside a new coal plant with scrubbers, parcipitators and lime injection burning powder River basin coal. They go home and smoke weed as they tell each other about their moral superiority for cleaning up the world.
 
That smell reminds me of my time in the military where everything is diesel. Being a nostalgic smell ,I kind of like it in small doses.

All that could just be that your family has the genetic code that is susceptible to fumes or that your family just has a weak immunity. For every person that you can name that has lung trouble from what you think is diesel fumes I can name 10 that weren't. I've raised animals all my life and have seen 1st hand how there are too many variables in our environment to narrow the causes of disease and conditions down to one reason. Most of the time it's a combination of differences in the animal's environment. Humans are just a different animal.
Nature will always win and regardless of what we try to do the survival of the fittest will eventually win out. If it doesn't then the species will become extinct.

Ontario has a 1-800-rat-fink number to call and sic the Governemt on any vehicle blowing excessive smoke .
 

Those stinking essential oils. Plug in air frsheners, scented candles and timed spray bombs are some of the worst offenders of unbreathable air. .

That's amusing. Avoiding carcinogens! How? They are literally everywhere! And the best part is that there is NO WAY to AVOID them or get rid of them in the modern world!

Now when I see scientific research from a reputable source, not the EPA, I'll believe all the dead children from diesel particulate matter.

For someone who hates diesel so much you sure like to buy goods that wind up in the stores due to diesel power.

Do I see compact and small tractors making a comeback in gas anytime soon? Maybe with the tierIV imposed and tierV looming. But if someone figures out a cheap way to make the diesels compliant all bets are off. On the gas side they will have to design a fuel injection system, cat system and emission controls while getting long engine life and economy near that of a diesel. It would still be hard to sell because most people looking for something that sized in a tractor associate diesel with tractors. That's going to be the big thing, getting the city guy who wants to impress his neighbors convinced that gas is OK for a tractor.

While a DI gasser in small equipmemt makes sense in the US and Canada where diesel varies from similar to more expensive than gasoline per gallon. The rest of the world taxes gasoline as a luxury commodity which makes diesel somewhere between 2/3 to 3/4 the cost per gallon of gasoline . Even a small Tier V diesel can be cheaper to operate.
Consumers , most being short sighted will purchase diesel equipmemt no matter the up front me cost and additional ongoing lifetime maintenance costs .
Emissions legal DI gassers are showing up in outboards , ATV's , motorcycles and snowmobiles for a reason .
