<p>A halogenated substance such as a dioxin, a polybiphenyl chloride compound, e.g., PCB, a halogenated organic agricultural chemical, a halogenated organic compound, or a haloethylene compound is reacted with a substance which is chemically equivalent to the halogenated substance in decomposition and is lowly toxic or nontoxic, with the aid of a chemical substance such as an acid, alkali, or reducing agent, e.g., lithium aluminum hydride, a biological means such as a microorganism or an enzyme, or a physical means such as ultraviolet or ultrasonic. Thus, the halogenated substance can be dehalogenated and decomposed. Whether the halogenated substance has been decomposed can be easily detected or ascertained by thin-layer chromatography or UV irradiation.</p> |
