Industrial calibration lamps are sold for this intent; reflecting a liquid mercury price per oz fluorescent ceiling gentle into a spectrometer is a common calibration practice.[ninety five] Gaseous mercury can be found in a few electron tubes, together with ignitrons, thyratrons, and mercury arc rectifiers.
Human actions, nonetheless, are responsible for Considerably on the mercury which is unveiled into your ecosystem. The burning of coal, oil and Wooden as gas can cause mercury to be airborne, as can burning wastes that comprise mercury.
