Abstract

Anthropic activities cause negative environmental impacts on the environment. These practices include the accumulation of solid waste improperly, which results in public health problems. An example of this is the possible presence of fauna in an unbalanced way, posing a risk to the health of workers who provide services in the collection of recyclable materials. This research aimed to evaluate the possibility of the presence and the level of bioindication of the environmental quality of the species Blattella germanica, Tityus stigmurus, and Rattus norgevicus in the Recyclable Materials Collectors Association (Associação de Catadores e Catadoras de Materiais Recicláveis - Ascmari) of the Municipality of Iguatu-CE. The methodology used was descriptive and deductive, and from there, the three species were evaluated for bioindication. Thirteen parameters were considered for assessing the species, and three of them referred to the degree of danger of these animals. R. norvegicus was the one with the best bioindication results among the species studied, although the presence of these animals may result from the presentation of the others already mentioned in this research. Despite the need for further studies on bioindicators of environmental quality, they are an aid tool for management, evaluation, and environmental monitoring. The main limitation to the research was the impossibility of site visits due to the Covid-19 pandemic. The present work addresses the assistance in improving the environmental quality, health, and working conditions of scavengers and the possibility of applying scientific methodologies at a distance to benefit a given community.
