Compact and tubular florescent bulbs contain the very hazardous metal mercury. Mercury is liquid at room temps but can be very easily changed from a liquid to a vapor. This vapor is odorless and colorless. Bulbs contain mostly mercury vapor but may also contain tiny amounts of liquid mercury.
Here’s some important information on mercury exposure safety.
Health Effects: The health effects of mercury mainly depend on exposure route, duration, and level of exposure. The nervous system and kidneys are the most exposed to mercury. It is also known to cause harm in unborn children. Signs of mercury poisoning include tremors, changes in mood, impaired memory, and or skin irritation and allergy. If exposed to high levels of mercury you can expect coughing, chest discomfort, trouble breathing, nausea, vomiting and diarrhea, sore gums, eye irritation, severe tremors, and changes in behavior.
