Abstract: The effects on the green alga Chlorella vulgaris of 40 herbicides in 19 different chemical structure classes and with 11 dissimilar modes of action were studied through 96-h acute toxicity tests. Experimental results indicated that the average acute toxicity of acetolactate synthase (ALS)-inhibiting herbicides to C. vulgaris was close to those of the acetyl-CoA carboxylase (ACCase)-inhibiting herbicides and the lipid synthesis-inhibiting protoporphyrinogen oxidase (Protox) inhibitor. Their acute toxicities were higher than those of the microtubule process inhibitor, mitotic process inhibitor, the glutamine synthase inhibitors, and 5-enolpyruvyl-shikimate-3-phosphate synthase (EPSP synthase) inhibitors. The acute toxicities of auxin herbicides to C. vulgaris were the lowest among all herbicides tested and that of the photosynthesis-inhibiting herbicides was the highest.
