Acute and chronic effects of four commercial herbicide formulations on Ceriodaphnia dubia

Acute and chronic effects of four widely used herbicide formulations were determined in toxicity tests with neonates of the invertebrate, Ceriodaphnia dubia. In order of declining toxicity, 48-h LC50s were 14.36, 15.93, 32.99, and 35.36 mg/l of Micro-Tech, Bicep, Extrazine, and Lexone, respectively....

Description
Summary:Acute and chronic effects of four widely used herbicide formulations were determined in toxicity tests with neonates of the invertebrate, Ceriodaphnia dubia. In order of declining toxicity, 48-h LC50s were 14.36, 15.93, 32.99, and 35.36 mg/l of Micro-Tech, Bicep, Extrazine, and Lexone, respectively. Reproduction was inhibited at doses below the 48-h LC50s for three of the chemicals, and 7-d chronic values based on reproduction were 17.68, 8.84, 17.68, and 8.84 mg/l for Micro-tech, Bicep, Extrazine, and Lexone, respectively. These chemicals are not likely to directly impact invertebrates.
