Bleach Solution
The bleach bath converts metallic silver on film back to a silver halide through an oxidation reaction. An iron solution is commonly used to accomplish this. Used C-41 RA bleach may contain up to three parts per million (ppm) silver.
Developer
Most developers for black and white film contain a small percentage of hydroquinone. These developers, if disposed as an unused product will be dangerous due to hydroquinone levels. However, hydroquinone does not show up in used developer in concentrations that are considered dangerous waste because it is consumed during use.
Fixer and Bleach-Fixer Solution
Fixer allows silver to dissolve out of the film and paper into the solution. As a result, used fixer and bleach-fixer contain high concentrations of silver, usually between 3,000 and 8,000 ppm. Because of these high silver levels, used fixer is a dangerous waste.
