This article presents a study on rapid ecotoxicity indicators to monitor effluents and surface waters of the Meia Ponte River. Water pollution by emerging pollutants has been a concern due to their negative effects on ecosystems and human health. Physicochemical parameters, cytotoxicity using luminescent bacteria Vibrio fischeri, and phytotoxicity using Allium cepa and Lactuca sativa were evaluated. The results showed high values of total dissolved solids and electrical conductivity in several collection areas, indicating the presence of pollutants. In addition, the bioindicators demonstrated toxicity, mainly in untreated effluent samples and near the river mouth. This suggests the presence of pollutants in the Meia Ponte River, especially in the urban area of Goiânia, due to agricultural and livestock activities. [Extracted from the article]

This article presents a study conducted in the Meia Ponte River, in Goiás, with the aim of quantifying the presence of five antimicrobials in effluents and surface waters. Samples were collected at different points along the river, including a sewage treatment plant. The results showed the presence of metronidazole and sulfamethoxazole at all collection points, with values ranging from 0.1 to 45.5 ng/L and 0.1 to 502.7 ng/L, respectively. The other antimicrobials analyzed were not detected. These results highlight the need for monitoring the rivers that cross the Cerrado. [Extracted from the article]
