In the 16th century, before the term mandarin became widespread in the European languages, the word Loutea (with various spelling variations) was often used in Europeans' travel reports to refer to Chinese scholar-officials.
Why do some people get smelly gas after eating eggs? I really love eggs, but I get really bad, sulfurous and rotten egg-smelling gas after eating eggs. This doesn't happen when I eat foods which contain eggs in moderate amounts (cakes, etc), but it does happen when I eat hard-boiled eggs or fried eggs. I don't get any stomach cramps or any other symptoms of allergy, however.
But, like any energy source, natural gas must be used properly. Since natural gas is colorless and odorless, we add a harmless, non-toxic chemical that makes it easier to detect a gas leak before it can create a hazardous situation. The chemical, called mercaptan, smells a lot like rotten eggs. If you aren't familiar with it, call Columbia Gas of Massachusetts at 1-800-688-6160 and ask for a scratch-n-sniff card that provides you with a sample of the odor. In a concentrated form, the smell is almost unbearable.
