Use of Eisenia andrei as Bioindicator of Soil Toxicity of Agrochemicals

Abstract

Given the importance of soil as a source of water and nutrients for plants and other organisms, pollution of the soil ecosystem can have important consequences for all forms of life and the quality of food, water and the atmosphere. The indiscriminate use and undue disposal by most agricultural properties can increase the accumulation of agrochemicals in the soil causing contamination. The ecological niche of the earthworms characterizes them as very important organisms in the soil and as environmental bioindicators. The objective of this study was to evaluate the sensitivity of Eisenia andrei by means of leakage test in soils contaminated by two agrochemicals. The experiment was composed of four treatments: T1 (Wood soil + Herbicide), T2 (Wood soil + Insecticide), T3 (Cultivated soil + Herbicide), T4 (Cultivated soil + Insecticide), in a randomized block design and factorial scheme. About 2000 g of soil were placed in polypropylene trays lined with parchment paper, whose dimensions were 44 x 28.5 x 10.4 cm, filled to the height of 4 cm of soil layer. The agrochemicals used were: glyphosate and organophosphate. After 72 hours of addition of the agrochemicals, 6 adult individuals were added. After the 48-hour period, according to NBR ISO 17512-1, the evaluation was carried out. Through the analysis of variance and multivariate, it was found that organophosphate acts under individuals, regardless of soil, while glyphosate tends to have interaction with the soil type evaluated.
