“…The WQIs are commonly used in either the classification of surface waters (Boyacıoglu, 2010;Lermontov et al, 2011) or the assessment of beneficial use (Said et al, 2004) and water pollution (Akkoyunlu and Akıner, 2012;Bakan et al, 2010;Kannel et al, 2007;Zhang and Zhang, 2007). For example, Pesce and Wunderlin (2000) calculated the objective WQI (WQI obj ) on 20 parameters and the minimum WQI (WQI min ) on three key parameters (dissolved oxygen, electrical conductivity or total dissolved solids, and turbidity) to assess the effect of urban discharge on a receiving river water quality.…”

“…The only exception was the sampling site B3, which was supereutrophic. This scenario results from the large amount of phosphorus and high concentration of chlorophyll-a (Akkoyunlu and Akiner, 2012).…”

“…Their main advantage is to synthesize a complex reality in a single number and to define clear goals (Akkoyunlu and Akiner, 2012;Lermontov et al, 2009;Silva and Jardim, 2006). The ALPI is a classic example of water quality indices: suitable for the protection of the aquatic life that incorporates the most representative parameters, especially toxicity and eutrophication (CETESB, 2013).…”

Bacanga River Basin faces environmental problems related to urbanization and discharge of untreated domestic sewage, which compromise its ecosystem health. Due to the small number of studies that assessed its water quality, the present study aimed to assess the current status of this ecosystem based on the aquatic life protection index. Samples were carried out every two months, in a total of six events, in six sites along the basin, where the water samples were collected to assess physicochemical parameters and calculate the trophic state index and the index of minimum parameters for the protection of aquatic communities. The data were also compared with values determined by the resolution National Environment Council -CONAMA 357/05. Our results reveal significant changes in the water quality of Bacanga River Basin. An increase in nutrients and chlorophyll-a concentration led it to eutrophication. The surfactant values were high and put in danger the aquatic biota. Dissolved oxygen rates were below the values allowed by the resolution in most sites sampled. The current water quality is terrible for the protection of aquatic life in 61.92% of the sites sampled.Keywords: water quality, contamination, domestic sewage. Índice de proteção da vida aquática em uma bacia urbana do rio Bacanga no norte do Brasil, São Luís -MA ResumoA Bacia Hidrográfica do rio Bacanga (BHRB) apresenta problemas ambientais relacionados a urbanização e lançamentos de esgoto in natura que comprometem a qualidade desse ecossistema. Devido ao reduzido número de estudos associados à avaliação da qualidade da água no local, este estudo teve como objetivo avaliar a situação atual desse ecossistema por meio do Índice de Proteção da Vida Aquática. Seis amostragens bimestrais foram realizadas em seis pontos ao longo da bacia, coletando parâmetros físico-químicos para a aplicação do Índice de Estado Trófico e Índice de Parâmetros Mínimos para a Proteção da Vida Aquática, relacionando-os com a resolução Conselho Nacional do Meio Ambiente -CONAMA/357. Os resultados revelaram alterações significativas na qualidade da água da BHRB, o aumento de nutrientes e das concentrações de clorofila-a conduziram ao um estado geral de eutrofização. Os valores de surfactantes foram altos colocando em risco a biota aquática e as taxas de oxigênio dissolvido estiveram abaixo do permitido pela resolução na maioria dos pontos amostrados. A situação atual da qualidade da água para proteção da vida aquática é péssima em 61,92% dos pontos amostrados.Palavras-chave: qualidade da água, contaminação, efluentes domésticos.

“…Water quality index (WQI) has been extensively applied to monitor water quality in recent years, and is indeed a practical method considering critical environmental variables, which represent the pollution conditions of a water body [15,[59][60][61] . It depicts the composite influence of different water quality parameters [24] .…”

Water quality assessment in pastoral of Tibetan Plateau, which is water sources for about 40% of world's population and the runoff-yield area of Yellow rivers, is very important. In this paper, Xiahe county which belongs to Tibetan Plateau pastoral was investigated. Six parameters(via, chloride, COD, ammonia nitrogen, nitrate, fluoride, sulfate) were selected to assess the water quality and health degree by using fuzzy comprehensive evaluation methods. The hydrochemical type in surface water was of HCO3 --Mg 2+ -C a2+ type. The cations and anions in surface water were mainly from weathering and dissolution of carbonate rock. Results showed that the water quality in all 69 sampling sites was all of class Ⅰ. The integrated health degree reached more than 0.85 and the health rate were 100%. Although ammonia nitrogen was regarded as the main contamination factor, but it had a little effect on the entire body of water. Overall, the surface water qualities of most samples in Xiahe County was good condition.
