SUMMARY:

The Mundaú River Basin is undergoing an accelerated process of environmental degradation due to the deterioration of human actions such as: disposal of domestic sewage; inadequate collection and disposal of solid waste; silting; floods; discharge of untreated industrial effluents; indiscriminate exploitation of natural resources; low participation in the management of hydrographic basins, disorderly occupation and unconsolidated urbanization of risk areas and inadequate agricultural and fishing practices. These actions have compromised public health due to waterborne diseases and tourism to the main attractions of the region. Fishing has socioeconomic consequences, such as the reduction of employment opportunities in the Estuarine lagoon Mundaú-Manguaba Complex (CELMM) and harms sustainable local development and its surroundings. Cellulose alone accounts for approximately 40% of all available carbon stock in the biosphere. It is present in all plants, from highly developed trees to the most primitive of organisms; its content in these species can vary between 20 and 99%. Nanocellulose represents a new set of nanomaterials, which has a wide range of technological applications in the most varied scientific contexts. Desirable characteristics such as rigidity, low weight, hydrophilicity, biocompatibility and optical properties favor the use of this material in innovative applications. The biodegradable films will be prepared according to the casting technique, which consists of preparing a film-forming solution, using distilled water as a solvent. In this sense, the present work aims to study the development, characterization and evaluation of the application of films produced from nanocellulose and different concentrations of humic substances in the remediation of water contaminated with potentially toxic metals  present in the Mundaú - Manguaba lagoon estuarine complex, and propose strategies to minimize the impacts generated in the environment, with the use of ecologically correct, low-cost and environmentally favorable adsorbent materials.
