The toxicities of a polyunsaturated fatty acid and a microcystin to Daphnia magna
10.1002/tox.10003.abs
Polyunsaturated fatty acids (PUFAs) are essential components of zooplankton diets. However, studies with PUFAs from cyanobacteria indicate toxic properties. We investigated the toxicity of the PUFA γ‐linolenic acid and the cyanobacterial peptide toxin microcystin‐LR to Daphnia. The PUFA was acutely toxic at a concentration of 9 μg ml−1. The effect of microcystin‐LR was not statistically significant at the concentration used (3 μg ml−1), but an additive effect with the PUFA was observed. Relative to LC50‐values of well‐known pollutants, the PUFA was intermediately toxic. The activity equaled that of microcystin‐LR, which is commonly treated as one of the most potent cyanobacterial toxins. Our results suggest that the toxic properties of PUFAs deserve more attention. © 2001 John Wiley & Sons, Inc. Environ Toxicol 16: 444–448, 2001
