Physicochemical parameters, levels of 2,4-D, estrogen hormones, and metals in Santo Antônio River (Brazil-Argentina): ecotoxicity and effect on water quality of the Iguaçu National Park
The Santo Antônio River, a surface watercourse forming part of the Brazil-Argentina border, is a tributary of the Lower Iguaçu River, region that houses the biodiverse Iguaçu National Park. This study aimed to assess its impact on the Iguaçu River’s water quality. Samples were collected at 10 points: eight along the Santo Antônio River (P1 to P8), from source to mouth, and two in the Iguaçu River, upstream (P9) and downstream (P10) of the Santo Antônio’s mouth. Physicochemical analyses revealed turbidity above the limit in P6, P7, P8, and P10 and higher than allowed biochemical oxygen demand (BOD) at all points. The hormone estriol (E3) was detected in all samples (10.50 to 30.54 μg.L⁻1), while 17β-estradiol (E2) was detected only in P2. The herbicide 2,4-D exceeded the limits in P3, P6, P7, P8, and P9. High concentrations of aluminum and iron were found in P8, with manganese above the limit in P8 and P10. In the sediments, high concentrations of chromium, nickel, and copper were confirmed at several points. Ecotoxicological tests with Artemia salina indicated high mortality in several points. Lithobates catesbeianus and Allium cepa showed cytotoxicity and mutagenicity at multiple points, while Eisenia fetida and Lactuca sativa did not present significant toxicity. Human liver cells (HuH7.5) had proliferation in P1, P2, and P8, while P9 and P10 showed cytotoxicity. The results show that the Santo Antônio River contributed to the degradation of water quality in the Iguaçu River, especially in terms of turbidity, BOD, hormones, metals, and ecotoxicity for A. salina.

Determination of Toxicity at Different Trophic Levels of Aqueous Film-Forming Foams (AFFF) Used in Fire Fighting
Aqueous film-forming foams (AFFF), containing perfluorinated surfactants, can reach the environment. The objective of this study was to determine the ecotoxicity of AFFF, according to the type of fire to be fought (A1: 1.05 g.L− 1, A2: 3.15 g.L− 1 and A3: 6.30 g.L− 1), to bioindicators of different trophic levels. For Artemia salina a toxic effect was observed at sample A1 (at concentrations of 100%), A2 (at concentrations above 25%) and A3 (at concentrations above 12.5%). For Lactuca sativa all samples affected the number of germinated seeds, speed and percentage of germination and root length. To the Eisenia fetida earthworm, samples A2 and A3 were considered toxic due to the percent avoidance being 70% and 100%, respectively. In Macaca mullata renal cell culture test, none of the samples were toxic by the MTT test. Therefore, it is necessary to develop methods for the safe use of AFFF by professionals.
