Risk assessment...
In light of the smoking thread, I was curious about how dangerous smoking was compared to second hand smoke exposure or significant exposure to diesel emissions. From here I read that the influence of second hand smoke isn't too bad compared to one pack a day, with someone consistently (I'm guessing.) exposed to second hand smoke have a 25% increased risk of lung cancer compared to the average, and someone who smokes on pack a day having a 2500% increased risk of lung cancer compared to the average. So, second hand smoke is more dangerous than air, in most places, but what's up with all those second hand smoke kills commercials I'm seeing? Are they valid, or are there greater threats when it comes to lung cancer? Well, I found this, and it seems like workers exposed to diesel had an inordinately high rate of lung cancer. If two pack a day smokers (Greater than 2500% increased risk/one pack a day) have a 1 in 7 chance of dying from lung cancer, and ~1 in 10 railway workers die from lung cancer, what are people who live in CA near the LA Harbor or by the trucking terminals in Riverside/San Bernardino having to deal with? It seems like the one liner about living in these areas being the equivalent to smoking about a pack per day has some merit. And everyone deals with it. What would a pack a day for their formative years do to a child? :eek:
So, given the seemingly high risk associated with diesel pollution in certain areas, why aren't I seeing commercials like this about diesel emissions run on LA tv stations? For that matter, how dangerous are the driving styles and auto choices of parents to their children? Is driving a lifted F350 spewing black smoke out the back worse than second hand smoke alone? Bueller? Bueller? Bueller? :confused: |

I think the key difference is mentality. You can stop smoking. You can't stop your neighbor from idling his/her car for 10 minutes before leaving for work. And because so many people share this thought process, they don't see any harm in also idling their cars for 10 minutes before leaving for work. Quote:

Yes, based on exposure - it looks like pollution is worse than second hand smoke... But that wouldn't change the risk looking at second hand smoking independently. ----- I'll look more for the NOx paper tomorrow (the reason why I'm up late is now finished) - but I found this buried in my bookmarks (1100 premeature deaths as a result of In-use off-road diesel vehicles). https://www.arb.ca.gov/msprog/ordiese...OverviewFS.pdf |
I say overblown from the perspective of commercials, not the actual risk, since that money could be spent combating a greater threat. Especially in high risk communities. And, since production is controlled, it's easier to regulate. I suppose the proof's in the pudding, since CARB hasn't done anything to regulate outdoor/private second hand smoke, but they are going after offroad/marine/trucking for diesel emissions based on the ~6,500 deaths and ~$7 billion in externalities per year in CA alone. Not only that, but my dirty diesel bunny is cleaner (per hp*hr) than even semis built according to the 07 standards IIRC, and the owners have the gall to complain, since they might have to meet emissions standards passenger vehicles had in the mid seventies with primitive 21st century technology.... :rolleyes:
*puts the keyboard down and steps away from the rant* Edit- Oh yeah, majority vs leading, tomatoe tomato. Leading is what I meant, I swear. ;) |
