Resumo: | Abstract: This study investigated the impact of anthropogenic activities in Belém City, Brazilian Amazon, by comparing water quality and fish larvae communities in two creeks that flow into the Guamá River. One creek crossed a poor and crowded suburb of Belém while the other was located in an island section that was declared an Environmental Protected Area in 1997. Two sampling points were set in each creek and monitored over eight hours once every three months over a one year period. Strong variations of water quality were registered all year long and at all tides in BelémÆs mainland creek, along with, among other things, a very high number of thermotolerant coliforms. Few larvae were found. The water was considered unsuitable for human use and activities as well as for aquatic life. The island creek presented early signs of bacterial and nutrient contaminations during the rainy season, probably partly related to non point source pollution. In both creeks, larvae communities were almost exclusively composed of clupeiforms. All larval development stages were encountered. Higher densities and proportion of newly hatched larvae were registered during the dry season and associated with the presence of nitrate. The results of the study show that adequate sewage and drainage systems must be developed in the city and suggest that it would be useful to conduct an integrated ambient monitoring study in Combú Creek. |

Um dos igarapés atravessa um subúrbio pobre e populoso de Belém, enquanto o outro é localizado em uma ilha de Belém, declarada Área de Proteção Ambiental desde 1997. Dois pontos de coletas foram definidos em cada igarapé e monitorados durante oito horas, a cada três meses e durante um ano. O igarapé em região urbana apresentou fortes alterações na qualidade da água, durante o ano todo e em todas as marés, e isto deve-se essencialmente a presença de um elevado número de coliformes termotolerantes. Poucas larvas foram encontradas. A água foi considerada imprópria para uso e atividades humanas, assim como para a vida aquática. O igarapé da ilha apresentou primeiros sinais de contaminação por nutrientes e bactéria durante o período chuvoso, parcialmente decorrente de fontes de poluição difusa. Em ambos os córregos, as comunidades larvais foram quase exclusivamente compostas de clupeiformes. Todos os estágios de desenvolvimento larval foram encontrados. Densidades e proporções mais elevadas de larvas recém eclodidas foram registradas durante a estação seca e associadas à presença de nitrato. Resultados apontam a necessidade de desenvolver um sistema de drenagem urbano para esgoto e água pluvial na maior brevidade, e recomenda um estudo de monitoramento integrado do igarapé na Área de Proteção Ambiental.Universidade Federal do Pará.

Abstract: This study investigated the impact of anthropogenic activities in Belém City, Brazilian Amazon, by comparing water quality and fish larvae communities in two creeks that flow into the Guamá River. One creek crossed a poor and crowded suburb of Belém while the other was located in an island section that was declared an Environmental Protected Area in 1997. Two sampling points were set in each creek and monitored over eight hours once every three months over a one year period. Strong variations of water quality were registered all year long and at all tides in BelémÆs mainland creek, along with, among other things, a very high number of thermotolerant coliforms. Few larvae were found. The water was considered unsuitable for human use and activities as well as for aquatic life. The island creek presented early signs of bacterial and nutrient contaminations during the rainy season, probably partly related to non point source pollution. In both creeks, larvae communities were almost exclusively composed of clupeiforms. All larval development stages were encountered. Higher densities and proportion of newly hatched larvae were registered during the dry season and associated with the presence of nitrate. The results of the study show that adequate sewage and drainage systems must be developed in the city and suggest that it would be useful to conduct an integrated ambient monitoring study in Combú Creek. |
