Environmental Impact 1,4-Naphthoquinone may be released into the environment through its use as a chemical intermediate in the production of dyes and pharmaceuticals and by its use as an algicide and fungicide. In the environment it will probably biodegrade fairly moderately in soil and may degrade in surface water. Its fate in ground water is unknown. Being related to vitamin K, (vitamin K1 and K2 are alkylated derivatives of 1,4-naphthoquinone), it is apt to be metabolized as is vitamin K. It is expected to have moderate absorption to soil and sediment and not bioconcentrate in fish.
Environmental Fate TERRESTRIAL FATE: If released on soil 1,4-naphthoquinone would be expected to biodegrade fairly rapidly. It would have moderate adsorption to soil and evaporate from the soil surface. AQUATIC FATE: The fate of 1,4-naphthoquinone in water is unknown. It might be expected to biodegrade (see also BIOD), adsorb moderately to sediment and volatilize slowly from water, but there are no experimental data. ATMOSPHERIC FATE: The fate of 1,4-naphthoquinone in the atmosphere is unknown. Although it absorbs light in the visible region of the spectrum, it is not known whether it photolyzes.
