At the study period, solid waste present in the environment was collected without no selection and stored in plastic bags to be later taken and analyzed in the laboratory. A total of 1,448 items were collected during the research period, being classified into six categories, totaling about 58 kg of garbage, most of which is plastic waste. plastic bottles soda, disposable materials, grocery bags, sandals and mineral water bottles were the five solid residues identified in greater amount. Maragojipe was the municipality with the highest volume collected, while in São Francisco do Conde, the beach area presented a greater number of residues than than the mangrove. To minimize these problems in the municipalities, the Environment should carry out more effective awareness campaigns for the population, about the risks that can be caused to aquatic species and to man himself. In addition In addition, there must be a more efficient work of urban cleaning, mainly in these areas of mangroves, which with the flow of the tides favor the deposit of waste in these environments.
