ABSTRACT

O objetivo deste trabalho foi avaliar os padrões qualitativos dos recursos hídricos localizadas no Parque Municipal dos Xetás na cidade de Umuarama (PR), o local é considerado Área de Proteção Ambiental, onde possui algumas fontes de poluição gerando conhecimento das condições físico-químicas e bacteriológicas para os habitantes da cidade ou para outros indivíduos. Foram analisados os parâmetros como demanda química de oxigênio (DQO), cor aparente, óleos e graxas, nitrato, surfactantes, turbidez, pH, chumbo e mercúrio em amostras coletadas de pontos específicos. As análises foram realizadas segundo as especificações do Standard Methods for Examination of Water and Wastewather e obtiveram-se teor mínimo e máximo que variou no resultado do DBO de 2,40 e 25,50 mg de O2/L, cor aparente variou entre 36,00 e 146 mg Pt-Co/L e óleos e graxas variou entre 8 e 28,5 mg/L de acordo com especificações vigentes todas as análises deveriam estar ausentes. Não foram detectados DQO, nitrato, surfactantes, turbidez, pH e mercúrio nas amostras analisadas. No microbiológico os coliformes totais foram de 3,0 x104 e 6,0 x105 e coliformes termotolerantes entre 1,0 x104 e 1,6 x107 nas amostras analisadas. A análise de mercúrio foi realizada pelo laboratório de análises toxicológicas e ambientais (LATAM) de Curitiba-PR, as análises microbiológicas de coliformes termotolerantes e coliformes totais analisadas pelo laboratório da SANEPAR conveniada com a UNIPAR e as demais análises foram realizadas no laboratório da Universidade Paranaense ­ UNIPAR. Concluiu-se que os efeitos causados pelas emissões de esgotos clandestinos de alguns pontos da cidade sendo estes, despejados nas nascentes do Parque Municipal dos Xetás, foram significativos de acordo com os parâmetros da portaria 518 do ministério da saúde e pela resolução 357 do CONAMA.


The purpose of this study was to evaluate the quality standards of water resources located in the Xetás municipal park in the city of Umuarama (PR). The site is considered an Environmental Protection Area. The study area has some pollution sources generating knowledge of the physical-chemical and bacteriological conditions for the inhabitants of the city or to other individuals. Parameters such as chemical oxygen demand (COD), apparent color, oils and grease, nitrate, surfactants, turbidity, pH, lead and mercury were analyzed in samples collected at specific points. Analyses were carried out according to the specifications set forth in the Standard Methods for Examination of Water and Wastewater, presenting minimum and maximum content BOD results that varied from 2.40 and 25.50 mg O2/L, apparent color ranged from 36.00 and 146 mg Pt-Co/L, and oils and grease ranged between 8 and 28.5 mg/L. According to existing specifications, all analyzes should be absent. No results for COD, nitrate, surfactants, turbidity, pH and mercury were found in the samples analyzed. In microbiological examinations, total coliforms were 3.0 x104 and 6.0 x105 and thermotolerant coliforms ranged between 1.0 x104 and 1.6 x107 in the analyzed samples. The analyses were carried out in the laboratory of the Universidade Paranaense ­ UNIPAR; mercury analyzes were carried out by the laboratory toxicological and environmental (LATAM) of Curitiba-PR, and the microbiological analysis of thermotolerant coliforms and total coliforms were analyzed by SANEPAR laboratory outsourced by UNIPAR, and the remaining analyzes were performed in the laboratory of the Universidade Paranaense - UNIPAR. It can be concluded that the effects caused by the emissions of clandestine sewage from some points of the city being dumped at the water sources of the Xetás Municipal Park were significant according to the parameters set forth in Ordinance 518 of the Ministry of Health and Resolution 357 by CONAMA.
