Johnson-Arbor and Schultz 2021 — Residential elemental mercury exposure and remediation
This case report documents residential elemental mercury exposure, delayed recognition through urinary biomonitoring, and the practical steps required for home decontamination. It is an a4 exposure source rather than a product paper. Its HMI value is the combination of human biomarker data, exposure circumstances, and concrete remediation lessons after indoor mercury contamination.
Key numbers
- The index patient had an initial urine mercury result of 216 ug/g creatinine (reference: <4 ug/g creatinine).
- A repeat 24-hour urine assay was 30 ug/L (reference: <20 ug/L).
- The patient’s husband had a 24-hour urine mercury concentration of 22 ug/L.
- The home required several weeks of professional remediation after vacuuming redistributed elemental mercury vapor.
Methods (brief)
Case report based on clinical toxicology evaluation, urine mercury testing, exposure history, and public-health remediation of a contaminated home. The exposure source was elemental mercury purchased online and used for recreational barometer calibration; vacuum cleaning worsened vapor spread.
Evidence Fitness
Strong for a4 exposure, biomonitoring, and remediation context. Not applicable to a1 occurrence routing. This is a practical toxicology/remediation source about household mercury exposure rather than a food or personal-care contamination survey.
Implications
Health: Useful for mercury exposure pages because it shows how urinary biomonitoring can identify chronic household exposure and how delayed recognition can prolong contact.
Mitigation: Useful for remediation pages because it documents that vacuum cleaning should not be used after elemental mercury spills and that larger spills may require professional cleanup and temporary relocation.
