Ethical considerations were considered All workers were subjected to structured interview questionnaire,occupational,medical assessment and bilateral nerve conduction for motor and sensory functions of median and ulnar nerves. Paint workers were 16 rag bucket,10 sprayers, 8 mixers and 6 assistants while 6 service workers,6 administration employees and 8 security workers as controls.

Eleven painters had symptoms of polyneuropathy.One painters had numbness,tingling,distal weakness in the upper limb.Nerve Conduction Velocity NCVs measurement showed statistically significant lowering mean NCVs of sensory,motor radial and median nerves velocities among the exposed workers Vs non- exposed. Median Nerve Sensory conduction velocity was: terminal C.V. was 41.4 ± 6.1 m/s Vs 52.3 ± 6.1, distal latency was 3.7 ± 0.5 Vs 3.5 ± 0.5 and amplitude was 37.1 ± 13.6 Vs 52.9 ± 21.3. The findings of Ulnar Nerve Sensory conduction velocity are: terminal C.V. was 37.5 ± 6.2 m/s Vs 55.4 ± 7.6(p < 0.01), distal latency was 4.2 ± 1.7 Vs 3.7 ± 0.4(p > 0.05) and amplitude was 26.2 ± 13.1 Vs 45.9 ± 20.2(p < 0.05). The motor median and ulnar nerve conduction velocities were: for median nerve: 50.6 ± 10.1 Vs 59.0 ± 4.2 (p < 0.01) and for ulnar nerve: 48.4 ± 10.5 Vs 60.5 ± 3.9 (p < 0.01).

There were statistically significant difference regarding NCVs between workers used complete PPE, incomplete uses and the control group except sensory latency of ulnar sensory nerve and motor amplitudes of median nerve.

Exposure to paints, age and smoking were found to have significant effects on NC measurements of the studied population. Among the exposed group, using of PPE, type of job and duration of exposure in years had significant effects on certain NC parameters.
