Abstract: Microplastics, defined as particles <5 mm in diameter, are emerging environmental pollutants that pose a threat to ecosystems and human health. Ecosystems are under serious threat from microplastic contamination, which affects both biotic and abiotic elements. Diverse and extremely complex pollutants known as microplastics spread other toxins and bacteria. There are now several ways to get rid of microplastics, including recycling, landfilling, incineration, and biodegradation. This review systematically summarizes the factors affecting degradation of microplastics.....

Abstract: The pilot research had as main objective recognise and discuss the geosocioenvironmental realities with emphasis in the quality of the water of Pará River in the stretch of Furo das Marinhas and Tracuateua River in the metropolitan region of Belém. Field research was made, with exploratory traits, as part of the technical scientifical contents of the discipline Introduction to the Environmental Science from Chemistry course in the Campus of Ananideua from the Federal University of Pará. It was examined in locus the conditions of water in those rivers, from Where quali-quantitative physiochemical samples were collected and analysed to identify the quality of water in part of the hydrographic basin. The analyses were determined following the procedures conceded by Guedes (2023). Through this, it was understood the challenges faced, with proposal of solutions to promote and preserve de water resources. As conclusion, it is observed the presence of detritus and sewage on the stretches of Pará River, causing impacts on health and environment, needing public policies of garbage collection and selective garbage collection, as well as Investments on environmental education.

Abstract: The availability of clean and reliable groundwater is essential for the sustainment of human and environmental health. Groundwater is a crucial resource that contributes significantly to the total annual supply. However, over- exploitation has depleted groundwater availability considerably and led to some land subsidence. Determining the potential zone of groundwater is vital for protecting water quality and managing groundwater systems. Groundwater potential zones are marked with the assistance of Geographic Information System techniques. During the study, a standard methodology was proposed to determine groundwater potential using an integration of GIS and AHP techniques. When choosing the prospective groundwater zone, accurate information was generated to get parameters......
