“…Aquatic macrophytes have been used for monitoring the contamination level by various pollutants in aquatic environments (Sawidis et al, 1995), including organic matter and nutrients such as P and N in wetland systems (Borges et al, 2008) and heavy metals, such as Zn (Wolff et al, 2009), Hg (Molisani et al, 2006) and others as these plants have the ability to accumulate metallic ions (Devi et al, 1996). The use of these plants as bioindicators of contamination by heavy metals has advantages: a) high tolerance to the pollutant, b) easy sampling, c) selective absorption ability, and d) individuals are relatively big and easy to handle in laboratories (Lewis, 1995;Zhou et al, 2008).…”

“…Observa-se, ainda, que os valores de turbidez obtidos nos tratamentos com plantas foram bastante inferiores aos valores do efluente da lagoa de atual tratamento e do descarte. Borges et al (2008), ao avaliarem um sistema de áreas alagadas pelo rio Corumbataí em Rio Claro (SP), com a macrófita E. crassipes, obtiveram uma taxa de remoção de turbidez de 96,8% para um período de detenção de 20 dias.…”

“…Verifica-se, assim, que o sistema de tratamento pelas plantas utilizadas tornou o efluente adequado a esse parâmetro dentro do exigido pela resolução brasileira (CONAMA, 2005). Borges et al (2008), ao analisar um sistema de áreas alagadas com a macrófita E. crassipes, em escala laboratorial, na intenção de reduzir nutrientes e microrganismos da água do rio Corumbataí em Rio Claro (SP) obtiveram uma taxa de remoção de turbidez de 96,8% para um período de detenção do esgoto de 20 dias. Salati et al (1999) em uma estação composta por um sistema de solos filtrantes e canais de macrófitas no bairro de Emaús em Ubatuba (SP), observaram uma remoção de 95% de turbidez no esgoto doméstico.…”
