Abstract

Abstract This study presents a system to electro-neutralize agrochemicals in food and water samples based on the properties of a controlled electron trap, the related apparatus is protected under patent application (WO/2018/090110; INPI: BR 10 2016 0268486) / (PCT / BR 2017/050115). The efficacy of the system was verified as to the type, quantity, surface tension charge, temperature, pH and static energy loading of the electrolyte for both solid and liquid samples. It also took into consideration the retention and accumulation measurement of electric charges, verification of electrical potential differences and also accumulation by applying pulsed high voltage in according to the Daniell Cell method. The proposed technology is able to provide the electron-neutralization of acidic and alkaline chemicals and their toxic byproducts by modifying the pH of the liquid or solid medium. This is justified by the action of the electron trap using different polarities and electrodes in the range of 8 to 100 kV.

Highlights

Brazil is a major worldwide consumer of food containing agrochemicals
Some of them consist in using potassium or sodium bicarbonate in alkaline solution in order to neutralize acidic pesticides (90% of the most used) and using acetic acid to neutralize the alkaline pesticides (Carneiro et al, 2015; Associação Brasileira de Saúde Coletiva, 2018; World Health Organization, 2018)
The pH reduction was more significant in both Distilled water (DW) and Water from public network (WPN) samples

Summary

Introduction

Brazil is a major worldwide consumer of food containing agrochemicals. According to the National Cancer Institute (INCA), the Brazilian Association of Collective Health (Abrasco), and the Oswaldo Cruz Foundation (Fiocruz) data on the consumption of such substances are worrisome (Agência Nacional de Vigilância Sanitária, 2014, 2018; Associação Paranaense das Vitimas Expostas ao Amianto e aos Agrotóxicos, 2018; Bassil et al, 2007; Bastos et al, 2011; Belmonte, 2018; Carneiro et al, 2015; Associação Brasileira de Saúde Coletiva, 2018; Duvoisin, 2016; Eustachewich, 2018; Food and Drug Administration, 2011; Instituto Nacional de Câncer, 2010, 2018; Jardim et al, 2009; Magalhães et al, 2018; Masur, 2018; Mourão & Marques Abramov, 2013; Oliveira et al, 2016; Peres et al, 2005; Rosalles, 2017; Rossi, 2015; Scientific American Brasil, 2016; Sperb, 2016; Velleda, 2017; World Health Organization, 2016, 2018).The use of agrochemicals tends to increase around the world, since the viability and productive security of agriculture are still based on the productive benefits that modern agrochemicals provide. Brazil is a major worldwide consumer of food containing agrochemicals. According to the National Cancer Institute (INCA), the Brazilian Association of Collective Health (Abrasco), and the Oswaldo Cruz Foundation (Fiocruz) data on the consumption of such substances are worrisome (Agência Nacional de Vigilância Sanitária, 2014, 2018; Associação Paranaense das Vitimas Expostas ao Amianto e aos Agrotóxicos, 2018; Bassil et al, 2007; Bastos et al, 2011; Belmonte, 2018; Carneiro et al, 2015; Associação Brasileira de Saúde Coletiva, 2018; Duvoisin, 2016; Eustachewich, 2018; Food and Drug Administration, 2011; Instituto Nacional de Câncer, 2010, 2018; Jardim et al, 2009; Magalhães et al, 2018; Masur, 2018; Mourão & Marques Abramov, 2013; Oliveira et al, 2016; Peres et al, 2005; Rosalles, 2017; Rossi, 2015; Scientific American Brasil, 2016; Sperb, 2016; Velleda, 2017; World Health Organization, 2016, 2018). Some of them consist in using potassium or sodium bicarbonate in alkaline solution in order to neutralize acidic pesticides (90% of the most used) and using acetic acid (vinegar) to neutralize the alkaline pesticides (Carneiro et al, 2015; Associação Brasileira de Saúde Coletiva, 2018; World Health Organization, 2018)
