Toxic metal fumes from mantle-type camp lanterns.
The mantle of a gas lantern contains about 600 micrograms of toxic beryllium metal. Most of the beryllium is volatilized and becomes airborne during the first 15 minutes of use of a new mantle. The inhalation of this quantity of beryllium can be hazardous.
