*2.4. Antiepileptics*

For CAR, once again, the pattern of acute data, was similar to that registered for anxiolytics and antibiotics, with the lowest concentrations promoting toxicity at 10.0 μg <sup>L</sup>−1, 20 000 μg L−<sup>1</sup> and 0.01 μg L−<sup>1</sup> for algae, fish and invertebrates, respectively [27,44,57]. Considering the chronic data, similar concentrations were found to produce toxicity in invertebrates and fish trophic levels, ranging from 25 to 25,000 μg L−<sup>1</sup> [27,29].
