Análise sazonal de parâmetros fisicos e químicos do Lago Luzio de Freitas na cidade de Inhumas-GO

Abstract

The present work aimed to analyze the water quality of Lake Luzio de Freitas, located in the city of Inhumas-GO, during periods of drought and rain (seasonal) to verify the water quality of the lake with anthropogenic, surrounding natural factors and amount. Chemical and physical parameters such as ammonia nitrogen, dissolved oxygen, redox potential, pH, temperature, transparency (turbidity), orthophosphate, hardness, iron and conductivity were analyzed, and the results were treated with descriptive statistics. To identify the sampling points, physical observation of the site was used as a method of methodology. The results showed that the water of Luzio de Freitas lake is in a process of eutrophication, inferring the anthropogenic influence on the causes of the alteration of the water quality, either by the materials from the garbage dump on the lake margins, the presence of animals that lie on farms adjacent to the lake and even the erosive process on its shore.
