Eczema's cause could be in the air we breathe

Makes sense with all the nitrated PAHs in the air. Not surprising that ammonia would also be identified since it's pretty much toxic to every part of the body. Yet another argument for keeping the sleeves down and bloused at all times while on duty.
I wonder what the characteristics are like after leaving the tail pipe in terms of air transport and phase stability. I believe ammonia and the other chemicals are soluble in water, so I imagine if the exhaust really is to blame, we would see higher rates of these conditions in very humid areas, or specific areas prone to fog. Even in a dry climate, there are particular places that tend to attract fog regularly and possibly concentrate the hazard for those who live or work in it.
Thanks for sharing!

Thanks for the info
