My husband agrees with you ... I should spend my time on something that will make a difference - even if it's just cleaning house. He thinks nothing will change and I am wasting my time.
And of course you are correct that mucous membranes would be affected (though to a lesser degree than the eyes or cuticle exposure areas). One worker of the Exxon Valdez oil spill cleanup said he was having a second operation on his sinuses (not doing well); another
had a massive nose bleed one night due to dry nasal passages. It makes you realize your mortality.
In the study being referenced by the World Health organiztion this isn't mentioned; however, esophageal cancer is one of the cancers gulf war vets have come down with. I wonder what other things?
There is such a thing as second hand exposure. I have several examples. The study by the World Health Organization (or whoever) is one I noticed first off. I think that the most serious exposure to this solvent is through one's eye membranes and thru the cuticle areas of one's hands. It would certainly dry out mucous membranes and I have heard of that, too.
If you just put in the search word, 2-butoxyethanol, on one of the internet search engines it goes on for pages and pages and pages. Some know more than I do; I just work in the area of 'let's give credit where credit is due' and the practical aspects of learning about it. For instance has 2-butoxyethanol poisoning ever been given as the main cause of harm to someone, per the CDC?
