Rapid mineralization of the endocrine‐disrupting chemical 4‐nonylphenol in soil
Abstract The persistence of the xenoestrogenic compound 4‐nonylphenol in agricultural, noncultivated temperate, and Arctic soils was assessed in laboratory microcosm incubations. At 30°C, [ ring ‐U‐ 14 C]4‐nonylphenol was rapidly mineralized without a lag in six soils tested. A sandy loam agricultur...
