| Question: | What forms of lead are detected and at what levels? |
| Answer: | - Full Disclosure is suitable for the detection of elemental lead, lead oxides, and some lead salts such as lead sulfate, lead nitrate, and lead acetate that can be solubulized by the mild acetic acid extraction solution included in the kit.
- The Full Disclosure extraction solution will not solubulize lead chromate. Full disclosure will not respond to alkly lead.
- Full Disclosure is not designed for and is not suitable for detecting lead in paint, paint chips, or on painted surfaces. The lead contained in paint is often encapsulated in a resin matrix that will not be broken down by the mild acetic acid extraction solution.
