Description
Zhao and co-authors present a 2025 study on an antibacterial chemical, triclocarban, and its effect on frog tadpoles. The chemical washes into waterways, yet its harm to amphibians was little known. Tadpoles of a Chinese frog species swam in water dosed at levels found in nature. The team tracked body form, gut microbes, and body chemistry together.
Short tests set the lethal level near one hundred seventy micrograms per liter. Longer exposure at far lower levels still left tadpoles in worse body condition. Gut microbe mixes shifted at several levels, and immune-linked chemicals in the body changed too. The authors warn that real-world levels already strain young frogs.
