BRUSSELS — The fungicide used in dandruff shampoo is not completely eliminated by wastewater treatment plants.

BRUSSELS — A new study published in the journal Environmental Toxicology and Chemistry has identified the damage that dandruff shampoos, which contain a considerable amount of fungicide, can do to water quality, according to an article by Newser.

The antifungal substance climbazole, commonly used in many over-the-counter dandruff shampoos, is not completely eliminated from water in wastewater treatment plants and can be found in concentrations of up to 0.5 micrograms per liter of water, the article reported.

The new study set out to characterize the ecotoxicity of climbazole and found that even low concentrations can harm living things such as algae and fish, according to the article.

The study also found a "reduction of frond size in water lentils and shoot length in higher plants" caused by climbazole, the article noted.
