- Abstract
According to the National Association of the Plant Defense Products Industry (Sindiveg), from 2012 to 2014 about 10% of all pesticides sold in Brazil were destined for the sugarethanol sector of the economy. Among the pesticides recommended by ANVISA (National Health Surveillance Agency) for pest control in plantations is the active ingredient carbofuran. A report by IBAMA (Brazilian Institute of Environment and Renewable Natural Resources) states that, in 2010 and 2013, respectively, around 2000 and 1700 tons of carbofuran were commercialized in different regions of Brazil, including the states of Goiás and Minas Gerais. Thus, this study aimed to verify the existence of soil contamination by carbofuran in samples from sugar cane plantations. The selected area for this investigation is located in the border of the states of Goiás and Minas Gerais, in the Southeast region of the country, where the cultivation of sugarcane is becoming more prevalent. The samples were taken in 0-20 cm depth. The analytical method used to verify the existence of soil contamination by carbofuran was solid-liquid extraction with low temperature partition, followed by analysis by high-performance liquid chromatography, coupled to an ultraviolet detector. The samples were collected in two different seasons of the year 2016, the first at the end of May and the second in mid-November. Within the established analysis conditions and the detection limit of the applied method, evidence of contamination by carbofuran was not found in the samples from the evaluated area.
