Going green

A 57-year-old man recently developed unnaturally green fingernails after spending several months working in an electronics start-up company in Canada.

The man's job involved mixing buckets of chemicals and occasionally dipping circuit boards into chemical baths containing isocyanate-based resins.

Although he reported always wearing latex gloves while working directly with chemicals, he admitted to his GP that they often became moist after he left them on for too long, and that he tended to use his bare hands to wash up utensils in the area.
