Abstract: PROBLEM TO BE SOLVED: To sharply reduce or prevent the formation of leaching mercurons and mercuric compound by oxidation of element state mercury by preventing dissolution of iron and copper from a lamp part by introducing a free-oxygen scavenger to a mercury vapor discharge lamp. SOLUTION: When an oxygen control agent is introduced into a structure of a mercury vapor discharge lamp such as a fluorescent lamp or a test solution, oxygen usable for oxidation of a metallic part to an oxidizing shape having oxidizing capacity to soluble mercury oxide of soluble and element state mercury reduces. Therefore, generation and dissolution of soluble ferric compound and soluble cuprous compound from a lamp part is reduced or prevented, and as a result, a loading mercury compound is reduced or prevented. That is the formation of leaching mercury when the fluorescent lamp is disrupted and is exposed to a filling-up condition, can be prevented or restrained to the minimum extent by preventing oxidation of several pats of the lamp.
