Mercury
88 published decisions mention Mercury. Most of them are deciding other claims at the same time, so the table below is narrower on purpose: it counts only the 46 individual issues where the claim itself was tied to this exposure. This is a non-presumptive agent, the medical link must be proven case by case, so these Board rulings are the roadmap.
What the Board has tied to Mercury
Each row: a condition claimed as related to Mercury, how many issues the Board ruled on, and the granted / denied / remanded split. Click a condition to see its code page, criteria, and the decisions.
What these numbers count: 88 decisions MENTION Mercury; of the issues inside them, 46 were actually tied to this exposure, and 9 of those appear in the table. A further 30 conditions came up too few times to chart (fewer than 5 issues each, 37 issues in total) and are not listed, because a single case cannot show a pattern.
| Condition | Issues | Granted | Denied | Rem. | Grant % |
|---|---|---|---|---|---|
| Hypertensive vascular disease (hypertension and isolated systolic hypertension) DC 7101 | 9 | 2 | 7 | 0 | – |

What the science says about Mercury
Mercury is a toxic metal found in some instruments, switches, dental amalgam, and industrial processes. Elemental mercury vapor is the main occupational concern; exposure is by breathing vapor.
Health effects documented in the toxicology literature
- Nervous system: Tremor, memory and mood changes, and other neurological effects from chronic vapor exposure.
- Kidneys: Can damage the kidneys.
- Other: Effects depend on the mercury form (elemental, inorganic, organic).
Cancer classification: Not classifiable / limited evidence, depends on form.
Latency: Neurological effects can persist after exposure ends.

Common questions
Is Mercury a presumptive exposure?
No. Unlike Agent Orange, burn pits, or Camp Lejeune, Mercury carries no automatic (presumptive) service connection. You have to prove the medical link yourself, usually with a nexus opinion, which is exactly why how the Board has ruled on it matters.
Why do so many of these conditions show denials?
The granted / denied counts reflect the mix of cases where Mercury comes up and how hard each link is to prove, not the merit of any one claim. A denial often means the file lacked a medical opinion tying the condition to the exposure, or proof of the exposure itself, not that the condition can never be connected.
How do I show I was exposed to Mercury?
Service records, your military job (MOS), unit history, and buddy statements can establish the exposure; a medical opinion then connects it to the diagnosed condition. This page reports Board outcomes and is not legal or medical advice, a VSO representative can help with your specific case.
