Abstract:The toxicity of triclosan (TCS) on the freshwater cladoceran Moina macrocopa was investigated by acute and chronic toxicity assessments followed by genotoxicity and oxidative stress response analyses. The 48‐h LC50 of TCS for ≤24‐h‐old M. macrocopa was determined as 539 μg L−1. Chronic exposure to TCS at concentrations ranging from 5 to 100 μg L−1 showed a stimulatory effect at low concentrations (≤10 μg L−1) and an inhibitory effect at high concentrations (≥50 μg L−1) on growth, reproduction, and population‐g… Show more
