My question is about a kind of grey area of "cooking", i.e. repurposing an old enamelware bread box, for example, to create a hot smoker. I've seen this work quite well. Wood chips go on the bottom of the box, a rack is positioned with food, the lid goes on, the whole box goes directly onto coals. In regular cooking, liquid contacts the chipped areas and mingles with the food directly. Do you think somehow lead and cadmium could be aerosolized by the hot smoker method?
You are looking for answers best left to a chemist. The United States Department of Agriculture states that you should not use a homemade cooker made of materials not intended for the cooking of meats as the process can create "chemical residue contamination."
