Animais domésticos (cães e gatos) e a rede hidrográfica da região central do município de Londrina-PR : a capacidade poluidora dos excrementos de cães e gatos e os riscos ao meio ambiente, à saúde humana e à saúde animal

Abstract

This dissertation is about the potential polluting capacity of the animal excrements which are improperly discarded in public areas of Londrina. The knowledge of the relevant theme "environmental impacts caused by the irregular evictions of human stool into streams and lakes", as well as the assurance that those excrements are potential sources of contamination of surface waters, justifies the search for the true extent in numbers related to the quantity of cats and dogs inhabiting the city. To accomplish this goal, it was implemented a specific assessment tool in two districts (which are Jardim Presidente and Jardim Pinheiros), near the lake that bathes the downtown area, where there is the possibility of causing risks to the environment and public health. The analysis of data obtained in the field research, as well as the bibliographical study led to the conclusion that it is necessary to discuss and implement solutions to the problem through public policies at the municipal level. Finally, some proposals are made in this regard.
