The objective of this study was to verify the impact of the anthropogenic action about the microbiological, cytotoxic and genotoxic quality of the Goiânia Botanical Garden.Microbiological analysis using the Most Probable Number (MPN) method for total and fecal coliforms, identification of the main contaminating strains through selective means, differential and biochemical tests; investigation of cytotoxicity and water genotoxicity by the Allium cepa test.The water samples collected in the Botanic Garden, presented contamination by total coliforms between 1.3 x 103 to 7.4 x 106 and fecal coliforms between 1.6 x 102 and 3.2 x 104 . Potentially pathogenic genera such as Escherichia coli, Klebsiella spp., Salmonella spp. and Pseudomonas spp., were identified. The water samples collected in two lakes presented significant results for cytotoxicity and genotoxicity for the A. cepa system. All the samples evaluated from the Botanic Garden water, presented low hygienic-sanitary quality, besides possible cytotoxic and genotoxic action in two lakes. These results plus the presence of environmental degradation, debris and litter at the site suggest a significant anthropogenic impact in this environment.porAcesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/Número mais provávelColiformesAllium cepaMost probable numberColiformsAllium cepaArtigo
