Resumo: OBJECTIVE: The assessment of water quality and phytoplankton community in recreational environments allows to setting management programs aiming at preventing potential harm to human health. The purpose of the present study was to describe phytoplankton seasonal changes in a freshwater system and their relation to water quality. METHODS: The recreational fishing lake is located in the southern area of the city of São Paulo, Brazil. Water samples were collected in three previously selected sites in the lake throughout a year and analyzed regarding floristic composition and physical and chemical parameters. RESULTS: The phytoplankton qualitative analysis revealed 91 taxa distributed among eight classes: Chlorophyceae, Cyanophyceae, Euglenophyceae, Zygnemaphyceae, Bacillariophyceae, Xantophyceae, Dinophyceae, and Chrysophyceae. Some physical and chemical parameters seemed to influence phytoplankton community behavior. Chlorophyceae development was favored by local conditions. Among the species of cyanobacteria identified, Microcystis paniformis, Cylindrospermopsis raciborskii, and Anabaena species were the most important due to their ability to produce toxins, posing a high risk to public health. CONCLUSIONS: Some physical and chemical parameters had an impact on the structure of phytoplankton community. The presence of Microcystis paniformis, Cylindrospermopsis raciborskii and Anabaena species indicates toxic potential and likelihood of public health problems unless there is constant monitoring. Further studies are recommended to prevent hazardous effects to the environment and public health.

OBJETIVO: A avaliação da qualidade da água e da comunidade fitoplanctônica em ambientes destinados à recreação permite estabelecer formas de manejo desses sistemas, evitando possíveis problemas à saúde humana. Assim, realizou-se estudo com objetivo de analisar a variação sazonal do fitoplâncton de um sistema lacustre natural, e sua relação com a qualidade da água. MÉTODOS: O lago estudado faz parte de um pesqueiro localizado na zona sul da cidade de São Paulo. Foram realizadas quatro coletas no período de um ano, em três pontos de amostragem. As amostras foram analisadas quanto à composição florística e às variáveis físicas e químicas da água. RESULTADOS: A análise qualitativa do fitoplâncton revelou o total de 91 táxons distribuídos em oito classes: Chlorophyceae (52%), Cyanophyceae (16%), Euglenophyceae (12%), Zygnemaphyceae (10%), Bacillariophyceae (5%), Xantophyceae (3%), Dinophyceae (1%) e Chrysophyceae (1%). Alguns dos parâmetros físicos e químicos parecem ter influenciado o comportamento do fitoplâncton; a classe Chlorophyceae foi a mais favorecida pelas condições ambientais. Dentre as espécies de cianofíceas identificadas, destacaram-se Microcystis paniformis, Cylindrospermopsis raciborskii e espécies de Anabaena, que apresentaram maior importância do ponto de vista sanitário devido à produção de toxinas. CONCLUSÕES: Algumas variáveis físicas e químicas da água interferiram na estrutura da comunidade fitoplanctônica. A presença de Microcystis paniformis, Cylindrospermopsis raciborskii e espécies de Anabaena indicam o potencial tóxico e os possíveis problemas que podem ocorrer à saúde pública, caso esse ambiente não seja continuamente monitorado. Estudos adicionais são recomendados, com a finalidade de se evitar efeitos deletérios ao ambiente e à saúde da população. Universidade de São Paulo.
