Mercury and Light Bulbs

Introduction

All fluorescent light bulbs contain some mercury. Some other lights also contain mercury:

  • high intensity discharge lamps (mercury vapor, metal halide, sodium)
  • fluorescent backlights in flat panel and liquid crystal displays commonly used as monitors, TVs and instrument displays.

Broken bulbs

When these light bulbs break, some mercury vapor is released to the air. Usually the amount released from one broken bulb is not a health concern.

Recycling bulbs

All mercury-containing lamps should be recycled. In Minnesota, it is illegal to dispose of mercury-containing light bulbs, or other mercury-containing products, in the trash.
