>I agree, except even if we as beekeepers don't use 'chemicals,' the forage they get into is often laden with chemicals, which they bring home and incorporate into their waxes.

The chemicals used at present for insects tend to either be systemic to the plant or short lived. The chemicals in the hive like cumaphos only break down in UV light. Maryann Frazier's work on what is coming into the hive showed mostly chemicals they took out of the hive.
