摘要

In sugarcane crops, several agricultural pesticides are applied simultaneously, and a set of these can be detected in groundwater and surface waters, characterizing a contamination by pesticides mixtures with different concentrations in these bodies of water. Thus, the aim of this work is to estimate the gray water footprint of the pesticide mixture (herbicides) used in a dystrophic Yellow Ultisol in a sugarcane cultivation system, in Pernambuco, Brazil, based on the toxicity of each pesticide used in the mixture. For this objective, the model proposed by Paraiba et al. (2014) was used, where the gray water footprint is determined by physicochemical characteristics of the soil and pesticides, the pesticide application rates (dose), and the lowest value of the effective mean dose of these substances in a population of organisms (EC50). The gray water footprint of the pesticide mixture was 1.32 x 10(5) m(3) ha(-1). The highest volumes of gray water and higher ranks of the mixture were due to Amicarbazone and Hexazinone, with 1.05 x 10(5) m(3) ha(-1) (r= 5) and 3.71 x 10(4) m(3) ha(-1) (r= 4.6), respectively, and the lowest values were due to Paraquat and Glyphosate, with gray water footprint of 1.64 and 8.43 m(3) ha(-1), respectively. The gray water footprint for the yield of the sugarcane crop was estimated at 1731.1 m(3) t(-1), considered a high value for the gray water footprint of the sugarcane, demonstrating how much this crop can demands water resources to dilute its load of contaminants.
