Abstract :

The study was carried out in the municipality of Cubatão, Baixada Santista, São Paulo, in the Casqueiro and Cubatão rivers. Three aquatic macrophyte species were used: water hyacinth (Eichhornia crassipes), lettuce (Pistia stratiotes) and Salvinia (Salvinia auriculata). The use of plants is to observe their ability to bioabsorb toxic chemicals present in the water, serving as bioaccumulation of toxins that cause damage to the species present in the hydric body and people who use. Some way these water bodies, since it is observed the use of these rivers as a source of obtaining food resources and recreation. The search for environmental recovery of these rivers is one of the tasks of this work, rivers that over the years were being destroyed by the addition of domestic and industrial effluents. It is known that many aquatic macrophytes have the power to bioabsorb toxic substances, whether with this study, to observe how much they can absorb and what would be the best species to use in the treatment of water, or if equivalence occurs in the power of biormediation of a degraded environment. These species are being used due to the ease of finding the same in the water bodies of the Baixada Santista, are being sampled from Lagoa da Saudade, Morro da Nova Cintra, Santos, in this location there is an abundance of these species, facilitating the Sampling. The plants were stored in plastic boxes with water from the rivers under study. Therefore this project helped to understand how much the environment itself can recover without intervention in fact of man who in the use of these 3 (three) species of plants we can in future recover both rivers and back bring aquatic life Diversified that inhabited it, we know that it is an intense work o but that with the help of the correct macrophyte for both rivers we can see good results before the rivers Casqueiro and Cubatão.
