Summary
This study demonstrates that former fluorescent lamp factory workers exposed to mercury vapor show lasting neuropsychological deficits and autonomic dysfunction years after exposure cessation. Dynamic pupillometry proved useful as a non-invasive tool for detecting sympathetic nervous system impairment, with implications for occupational health monitoring in lighting manufacturing environments.
Key Findings
- Former mercury-exposed workers had significantly higher Beck Depression Inventory scores than controls (p=0.025).
- Significant deficits were found in attentional span/SSP direct (p=0.004), spatial recognition memory/SRM (p=0.039), pattern recognition memory/PRM (p=0.001), and decision-making latency/IST (p=0.001).
- Dynamic pupillometry showed significantly lower '75% pupil diameter recovery time' response in former workers vs. controls at 10 cd/m² luminance (p=0.025), indicating sympathetic nervous system dysfunction.
- This is reported as the first use of dynamic pupillometry to assess autonomic nervous system function specifically in patients with prior mercury exposure.
