Metodologias de avaliação da qualidade ambiental em ecossistemas aquáticos continentais

Abstract

The present work aims to carry out a bibliographic survey on methodologies used to assess environmental quality in lotic ecosystems, and analyze the importance of these methodologies for this type of assessment, highlighting their positive and negative points, in addition to highlighting their forms of application . Highlighting traditionally used methodologies, such as the Water Quality Index (WQI), with a more efficient approach to detect environmental impacts, seeking to integrate physical, chemical and biological information on aquatic ecosystems brought by the analysis of these methods, in addition to highlighting other mechanisms of analysis of water quality and its relevance in each circumstance of use, seeking to improve efficiency in detecting environmental impacts. The importance of bioindicators as tools for assessing environmental impacts is also highlighted, highlighting their ability to respond to natural and anthropogenic disturbances.
