Authors: Wable Revati , Pardhi Prachi
Published: May 2021

Several types of Routing Protocols for mobile ad hoc networks have been proposed recently for their application in various
areas such as military, government and many other fields. In this paper, we have proposed a comparative study of various routing
protocols for mobile ad-hoc networks particularly emphasizing on its security aspect. Furthermore, we have discussed the comparison
among existing routing protocols for MANET. Main factor for comparison is routing methodologies and knowledge required to make
routing decisions. The comparison is made on the basis of the following factors: integrity, confidentiality, authentication, nonrepudiation and availability. Analysis of the secured version of proposed routing method has been done on the basis of the five security
requirements and the same has been shown in the comparison tables.

Published: May 2021

Over the years, zoonotic bacteria of the genus Salmonella, have acquired antimicrobial resistance properties, with a wide variety of resistance genes and resistance-mediating mutations being identified. This study isolated and characterized multiple drug resistant Salmonella species isolated from abattoir wastewaters in Abia State, Nigeria. Seven hundred wastewater samples from three abattoirs: Aba (300), Ubakala (250) and Lokpa (150) samples were analyzed from 2016 to 2019. Standard microbiological procedures were followed in isolation and identification of the Salmonella spp isolates. The antibiotic susceptibility test was done using the Kirby Bauer disk diffusion method. The results showed moderate but significant prevalence of Salmonella spp in the three abattoir locations; 135(45.0%) from Aba, 108 (43.2%) from Ubakala and 74 (49.3%) from Lokpa. The antibiotic susceptibility pattern of the Salmonella spp isolates show that the organisms were highly susceptible to Ofloxacin (84.4% in Aba, 89.8% in Ubakala and 82.4% in Lokpa) and highly resistant to Ampicillin (97.0% in Aba, 91.7% in Ubakala and 98.6% in Lokpa). Most isolates recorded Multiple Antibiotic Resistance (MAR) index greater than (>0.2). This result emphasizes the urgent need for regulation in the use of antibiotics in man and animals and their subsequent disposal into the environment.
Metric Routing Protocol for Detecting Untrustworthy Nodes for Packet Transmission
Authors: S Smys , Joe Vijesh
Published: May 2021

IoT objects that have a resource constrained nature resulting in a number of attacks in the routing protocol for lossy networks and low-power networks. RPL is very vulnerable to selfish behaviours and internal attacks though they are built with encryption protection to secure messages. To address this vulnerability, in this paper, we propose a novel trustworthiness methodology based on metric for incorporating trust evaluation, enhancing the robustness of security mechanism. Simulation results indicate that the proposed work is efficient in terms of throughput, nodes’ rank changes, energy consumption and packet delivery ratio. Moreover, using mathematical modelling, it has been observed that this methodology meets the demands of loop-freeness, optimality and consistency. This shows that this metic has both monotonicity and isotonicity requirements to enable the routing protocol. Incorporating the concepts of game theory, we can use this technique as a strategy to iterate Prisoner’s Dilemma. Both evolutionary simulation and mathematical analysis indicate that the proposed metric-based routing protocol is an efficient technique in promoting evolution and stability of the IoT network.

Identification of the microbiota in sugar extraction juices by sequencing-based techniques
Authors: Moser Cordula K. , Ukowitz Christina , Emerstorfer Florian , Hein Walter , Domig Konrad J.
Published: May 2021

The importance of microorganisms in the beet sugar industry came up in 1930. Since then, several approaches have been made to describe these bacteria. For this purpose, mainly cultivation-based methods were applied. However, the majority of the microorganisms cannot be cultivated or are in the viable-but-non-culturable state. In addition, these methods are time-consuming and costly. Progress in molecular biology allows a cheaper, faster and more precise identification of the microbiota. This study evaluates the application of an 16S rDNA-based metagenomic sequencing approach based on Illumina MiSeq technology to identify the microbiota in raw juice and juice of mid-tower in a beet sugar production plant and compares the results with those obtained by cultivation-based techniques. All bacteria orders detected with cultivation-based methods could be also found with the applied metagenomic approach. In raw juice, mainly mesophilic bacteria such as Lactobacillus spp. and Leuconostoc spp. species were identified. Additionally, a partly large proportion of gram-negative bacteria belonging to the order Enterobacterales were detected by the metagenomic approach. The diversity in juice of mid-tower was much lower and predominated by mainly thermophilic genera such as Geobacillus, Caldanaerobius and Thermoanaerobacter. The last two mentioned genera belong to the class of Clostridia. Surprisingly, in the juice of mid-tower Lactobacillus species could be verified by cultivation-based methods as well as by the metagenomic approach. As a consequence, it can be presumed that lactobacilli can survive in this very specific environment at 70 °C occurring in the central part of the extraction tower.
The SMRI-NIRS technology: development, validation and benefit
Authors: Walford Stephen N.
Published: May 2021

The Sugar Milling Research Institute NPC (SMRI) has developed a simple to use near-infrared spectroscopy (NIRS) transmission-based analysis method as an alternative to conventional methods for analysis of sugarcane factory stream samples. The technology provides rapid, simultaneous analysis of refractometric dry substance (rds), polarimetric sugar, sucrose, glucose, fructose, conductivity ash contents as well as colour and pH for all streams and additionally, dry solids for final molasses and eliminates the need for sample clarification chemicals. The analyte prediction equations were developed using conventional results of samples from 14 South African factories, analysed at SMRI using SANAS/ISO17025 accredited test methods, and NIRS scans of the same samples using up to 16 different NIRS instruments. The NIRS analyte prediction equations were validated against more than 1,500 independent factory samples that had been analysed by conventional methods of analysis, including samples from factories outside South Africa. The reproducibility of the NIRS results were equivalent to existing conventional analysis reproducibility values (juice and final molasses) and previously undocumented values determined for this study for conventional raw house analysis methods. Correlation coefficients of greater than 0.97 were recorded for all major analytes and greater than 0.9 for minor analytes when predicted results were compared against conventional results. A maintenance protocol was also developed to ensure that the prediction equations remain robust and can account for sample matrix variations that can occur from season to season. The SMRI-NIRS technology was installed at all 14 South African factories and found to be robust and give equivalent results to conventional methods of analysis.

Published: May 2021

Jumpai (Glinus Oppoitifolius (L.) Aug. DC) contains flavonoids compounds that can act as antioxidants by donating hydrogen so as to stabilize the lack of electrons in free radicals. This study aims to determine the antioxidant potential of stem, leaf, and flower extracts by looking at the IC50 value. The stems, leaves, and flowers were extracted by maceration using 70% l ethanol solvent. The results of the antioxidant activity test using the DPPH method (2,2-diphenyl-1-picrilhydrazil) showed very strong antioxidant activity with IC50 values of 9.523 µg / ml stem, 32.89 µg / ml leaves, and 23.07 µg / ml flowers with vitamin comparisons. C obtained IC50 value of 1,698 µg / ml. Based on these results, it can be rejected that the stems, leaves, and flowers have antioxidant activity with a very strong category against DPPH free radicals (2,2-diphenyl-1-picrilhydrazil).

Authors: Listyarini Risnita Vicky , Dewi Noer Kurnia
Published: May 2021

The need for paper continues to increase, indicating that there is an alternative wood material that can be used as a base for making pulp. Materials that can be used are dried banana leaves which contain cellulose. The quality of the pulp can be obtained by the characteristics of the pulp produced. This study was conducted to determine the effect of the type of solvents on the pulp quality of banana leaves. The pulp has been made using delignification process with addition of 3% NaOH or 3% Na2CO3 3% and heating up to 120 minutes, at 105 °C. Pulp quality was obtained from the results of pulp analysis, cellulose content, water content, physical appearances and qualitative analysis by FTIR. From the analysis of cellulose content, water content and FTIR instruments, pulp made with 3% NaOH solution are better suited to 3% Na2CO3 where the resulting pulp has a water content of 4.96%, a smooth and fibrous texture, a rich color, and produces a cellulose hydroxyl absorption band that is stronger than the pulp made of 3% Na2CO3. However, the pulp made from 3% NaOH solution has a lower yield (56.5%) and cellulose content (26.07%) than Na2CO3 3%. Dried banana leaves can be used as an alternative in pulp making.

Optimalisasi Adsorpsi Kitosan Dari Kitin Cangkang Keong Sawah (Pilla Ampullacea) Terhadap Logam Kadmium (Cd)
Authors: Moray Olivia Indra , Tani Djefry , Gumolung Dokri
Published: May 2021

This research aims to make the chitosan from the chitin of the Snail shell (Pilla ampulacea) which can be used as a cadmium metal adsorbent (Cd). It is derived from the isolation of the snail shells through 2 phases, which are deproteination to remove protein and demineralization to remove mineral salts. The formed Kitin is transformed into Chitosan by deacetylated using NaOH 60%. Kitin and Chitosan were acquired, identified by FTIR. The results showed that the chitin yield was 26.81% of the shell weight of 400 grams and the rendemen Chitosan was 31.78% of the weight of chitin.  The results of the identification indicate the absorption area of chitin and chitosan function groups, similar to the standard chitin and chitosan uptake areas. Metal adsorption Cd uses adsorbent chitosan from the shell snail (pilla ampulacea) Most optimal occurs at a contact time of 15 minutes and on the weight of adsorbent 0.25 grams, the most optimal absorption occurs at a comparison of 1:30 weight chitosan/volume solution Cd.

Authors: LUTKOVSKA Svitlana , KAZMYR Valentyna
Published: May 2021

The research conducted in the article allowed to identify problems, explore strengths and weaknesses, consider threats and alternative opportunities and identify priority areas for development of the grain market of Ukraine. In particular, it is noted that the grain market is a complex economic system, which is significantly influenced by climatic factors, demand, supply, pricing, government regulation, efficiency of institutions, the existence of appropriate infrastructure, the intensity of competition of economic entities and more. At the macro level, the efficiency of the grain market is influenced by the following key factors: environmental (climate change); demographic (population growth); energy (growing cereals for biofuels); attractiveness of the grain market for TNCs and transnational grain traders; underdeveloped infrastructure of the grain market; lack of effective instruments of state regulation of supply and demand in the grain market; low level of credit security (high level of interest rates); imperfection of insurance protection; low efficiency of budget support for agricultural producers. Priority areas for the development of the grain market are: improvement of the regulatory framework for the functioning of the grain market; improvement of protection measures for grain market entities; optimization of land tenure and land use; introduction of effective insurance protection; modernization of material and technical base of business entities; creation of an information portal based on e-logistics and digitalization (monitoring, forecasting); development of the export potential of the grain market; ensuring equal economic conditions for all subjects of the grain market; improving state support; promotion of agrarian integration and cooperation; raising the competence level of managers and managers of business entities; diversification of grain use; introduction of new credit and investment collateral instruments; development of grain market infrastructure; introduction of e-logistics.

Published: May 2021

The article outlines the role of the grain market, assesses its condition, identifies trends and develops new scientific approaches to strategic areas of improvement and development of the grain market, which will help overcome the information asymmetry of the market environment.It is noted that the grain market forms the basis of food security and significantly affects the living standards of the population, so qualitative and quantitative indicators of its condition, development trends are of strategic importance for the entire national economy, as it is a crucial prerequisite for sustainable growth. It is substantiated that the need for state regulation of the grain market is associated with the rapid growth of production of cereals and legumes, which generates additional challenges and problems, among which are the following: intensification of competition in global markets; lower world prices and, accordingly, falling export revenues; lack of capacity and storage space for reliable storage and quality processing of grain and their obsolescence; logistical capacity of domestic ports and rail transport; limited distribution channels; modern agricultural innovative technologies, providing high productivity, contribute to increasing unemployment in rural areas; low capacity of processing plants; deformation of traditional production chains. In addition, it should be emphasized that the COVID-19 pandemic has provoked a decline in incomes. The following directions of development of the grain market are defined: increase of transparency of the grain market; strengthening the importance of the state agent in the grain market; expansion of grain export channels; diversification of grain use areas; expanding the financial capabilities of grain producers; improving information support for the functioning of the grain market; increasing the effectiveness of state support programs; establishment of reliable distribution channels; assistance in entering world grain markets; formation of a protectionist environment for domestic grain market participants; creation of a favorable regulatory field for grain producers; timely provision of necessary public services in a pandemic.

ECONOMIC EFFICIENCY OF USE OF WASTE-FREE TECHNOLOGIES IN THE AGRO-INDUSTRIAL COMPLEX
Authors: VOVK Valeriia
Published: May 2021

The article explores the economic essence of the concept of “waste-free technologies” and it was determined that the main idea of waste-free production is the conversion of residues of secondary raw materials and waste obtained in the production process into finished products, which is able to bring economic benefits to the enterprise. Has been analyzed the dynamics of the volume of generated and utilized agricultural waste in Ukraine in 2010-2019. And it was determined that no more than 30% of waste is disposed of, the share of which has been rapidly decreasing in recent years. It was noted that the agro-industrial complex is one of the material-intensive and high-waste sectors of the economy, which accounts for a significant part of greenhouse gas emissions - more than 12%. It is concluded that the introduction of waste-free production technologies in agricultural enterprises of Ukraine will not only reduce the amount of waste generated and their impact on the environment, but it is also a source of income by replenishing the energy balance of enterprises.

Attention is paid to the most promising direction for the introduction of waste-free technologies at agricultural enterprises - the production of biogas from organic waste (biomass). It is noted that agricultural waste, mainly animal waste, such as manure, chicken droppings, can be an additional source of replenishing the energy balance of agricultural enterprises and ensuring the energy security of the region. Have been analyzed the volumes of animal waste generation in Ukraine and the potential for biogas production from manure in Ukraine in 2020.

A sample of the 10 largest biogas plants in Ukraine was carried out and the further development of the bioenergy sector in 2050 in terms of biogas production was predicted. 6 main environmental effects from the introduction of biogas complexes in Ukraine were identified. The main directions of the European Green Deal are characterized and the key areas of harmonization of domestic legislation on waste management are given with European ones.

Eleven samples of honey collected from different locations spread in the Baia Mare area and situated at various distances from the pollution source, the company Romplumb S.A. (while it has been in operation and after its closure in January 2012) were studied to determine the presence of the Pb and Cd by electrothermal atomic absorption spectrometry. It has been found that the concentration of lead and cadmium is generally correlated with the degree of pollution of the environment with these heavy metals, as well as with the distances from the pollution source and the directions of circulation of the contaminated air. In order to characterize the contamination of honey we introduced the index of contamination (IC) that shows a medium contamination for Pb and weak contamination for Cd in the period the pollution source was active and a weak contamination for Pb and no contamination for Cd after the closure of the metallurgical plant. We obtained a mathematical model representing the concentration of Pb in honey with respect to the geographical position in case the air was also contaminated with Pb, and showing more clearly the influence of air flows on the contamination of honey.

In the present note, we extend some univariate uniform approximation results by means of Lagrange interpolating polynomials [Ivan, M., Elements of Interpolation Theory, Mediamira Science Publisher, Cluj-Napoca (2004)] to the bivariate case. It is well known that generally, in the univariate case, the sequence of Lagrange interpolation polynomials does’t converges to the approximated function. This fact was first observed by G. Faber (see [9]), which constructed an example when the sequence of Lagrange interpolation polynomials diverges. The result of G. Faber was more generalized by I. Muntean (see [12]). M. Ivan established first sufficient conditions for the uniform convergence of the sequence of Lagrange interpolation polynomials associated to a univariate real valued function. First, we represent the remainder term of bivariate Lagrange interpolation formula in terms of bivariate divided difference. Using this representation we establish sufficient conditions for the uniform convergence of the sequence of bivariate Lagrange interpolation polynomials to the approximated function.

In this paper, we show that for every semispray S on a vector bundle (R × TM, π, R × M), there are several sequences of semisprays and correspondingly several nonlinear connections associated to it. It is important to derive conditions on S, which guarantee that a sequence of nonlinear connections associated to S is constant. We show that the homogeneity condition for S yields the result.

Prospective and multicenter observational cohort study of the blood cultures ordered in 74 Spanish emergency departments for patients with CAP seen from November 1, 2019, to March 31, 2020. The predictive ability of the model was analyzed with the area under the Receiver Operating Characteristic curve (AUC-ROC). The prognostic performance for true bacteremia was calculated with the chosen cut-off for getting the sensitivity, specificity, positive predictive value and negative predictive value. Results. A total of 1,020 blood samples wered cultured. True cases of bacteremia were confirmed in 162 (15.9%). The remaining 858 cultures (84.1%) wered negative. And, 59 (5.8%) were judged to be contaminated. The model´s area under the receiver operating characteristic curve was 0.915 (95% CI, 0.898-0.933). The prognostic performance with a model´s cut-off value of ≥ 5 points achieved 97.5% (95% CI, 95.1-99.9) sensitivity, 73.2% (95% CI, 70.2-76.2) specificity, 40.9% (95% CI, 36.4-45.1) positive predictive value and 99.4% (95% CI, 99.1-99.8) negative predictive value. Conclusion. The 5MPB-Toledo score is useful for predicting bacteremia in the patients with CAP seen in the emergency departments.

Az utóbbi években egyre többet olvashatunk az egyajánlatos közbeszerzésekről. Valahányszor szóba kerül a közpénzek elköltése közbeszerzések útján, természetszerűleg reflektorfénybe kerül az is, hogy volt-e verseny az adott közbeszerzési eljárásban és ha igen, akkor az milyen mértékű volt. A szakcikk konkrét példákon keresztül mutatja be, hogy milyen veszélyeket hordoz az egyajánlatos közbeszerzések leegyszerűsítő statisztikai mérése vagy a részajánlattételi lehetőségek mechanikus biztosítása. A szerzők rámutatnak az Európai Bizottság mérési módszertanának ellentmondásaira és javaslatot tesznek az egyajánlatos közbeszerzések pontosabb mérésére. Addig is, amíg ez nem következik be, a cikk javaslatokat fogalmaz meg, hogy miképpen lehetne javítani Magyarország esetében az Európai Bizottság mérési módszertana szerinti egyajánlatos közbeszerzések mutatóját úgy, hogy más bizottsági indikátor se gyengüljön.

Published: May 2021

In this study, a new and further generalized form of the fractional kinetic equation involving the generalized V$-$function has been developed. We have discussed the manifold generality of the generalized V$-$function in terms of the solution of the fractional kinetic equation. Also, the graphical interpretation of the solutions by employing MATLAB is given. The results are very general in nature, and they can be used to generate a large number of known and novel results.

Teknoloji-Etik İlişkisine ve “İyi-Yaşam” İmkânına Dair Bir Soruşturma
Authors: YILMAZ Erdal
Published: May 2021

Teknolojik alandaki gelişmelerin yaşamımızı köklü bir şekilde değiştirmesi ve kontrol altında tutmasıyla ilgili endişeleri günümüzde kesif bir şekilde hissetsek de bu, şüphesiz yeni bir durum değildir. Söz konusu endişeler, Martin Heidegger’in teknolojiye dair analizlerinde yaklaşık yarım asır evvel ele aldığı meseleler arasındadır. Heidegger’in teknoloji hakkındaki düşüncelerinin türlü disiplinler ve alanlarda epeyce ilgiyle karşılandığı ancak bunların etik ile olan ilgisinin çok sınırlı bir şekilde tartışıldığı görülür. Bunun nedeni olarak onun teknolojiye dair düşüncelerini çalışmalarında doğrudan etik ile ilişkilendirmemiş olması gösterilebilir. Heidegger’in teknolojiye dair soruşturması her ne kadar etiği doğrudan ilgilendiren bir içeriğe sahip olmasa da etik ve teknoloji arasındaki ilişkinin nasıl bir zeminde ilerlediği hakkında bize ipuçları sunmaktadır. Bu makalede, Heidegger’in felsefesinden hareketle teknoloji-etik ilişkisine ve “iyi-yaşam” imkânına dair bir soruşturma yapılmaktadır. Bu kapsamda, etiğin teknolojik düşünme tarzının bir ürünü olduğu ve cari etik yaklaşımların böyle bir zeminde vücut buldukları sonucuna ulaşılmaktadır. Ayrıca Heidegger’in teknolojik düşünmenin karşısında konumlandırdığı sükûnetle derin düşünme fikrinin, insana dair geliştirdiği varlığa-açık olma fikri üzerinden yeni bir etik yaklaşımı ve iyi-yaşam fikrini doğurabileceği iddia edilmektedir.
E-Devlet –Şeffaflık İlişkisi: Avrupa Ülkeleri İçin Panel Veri Analizi

Published: May 2021

Bu çalışmada modern kamu yönetimi anlayışının iki temel bileşeni olan şeffaflık ile e-devlet ilişkisini araştırmak amacıyla panel veri analizi yönteminden yararlanılmıştır. 26 Avrupa ülkesi için 2008-2018 yıl aralığındaki 2’şer yıllık veri kullanılmıştır. Sabit etkiler modeli ile gerçekleştirilen tahmin sonrasında e-devlet gelişim düzeyi arttıkça şeffaflığın arttığı bulgusuna erişilmiştir. E-devletin yanı sıra siyasal haklar, hükûmetin etkinliği ve kişi başı gayrisafi millî hasıladaki büyümenin etkisi ele alınmıştır. Siyasal hakların genişletilmesi ile şeffaflığın arttığı ve hükûmetin etkinliğinin artmasının da şeffaflığı arttırdığı görülmüştür. Gayrisafi millî hasıladaki büyümenin ise şeffaflığa etkisinin istatistiksel olarak anlamlı olmadığı görülmüştür.
"Her" Filminde “Benlik Tabusu”nun Yıkımı ve Etik Bir İmkan Olarak Satori
Authors: BÜTEV Sarper
Published: May 2021

Bu çalışmada, yapay zekâlı bir işletim sistemi olan Samantha ile aşk yaşayan Theodore’un bu ilişki sonucunda yaşadığı duygusal ve zihinsel dönüşümü konu alan "Her" (Spike Jonze, 2013) incelenmektedir. Çalışmada filmin felsefi referansının, düşünür Alan Watts’ın Taoculuk ve Zen düşüncesinden hareketle geliştirdiği ego psikolojisi eleştirisi olduğu ileri sürülmektedir. Zira, filmin 98. dakikasında Samantha, Theodore’u fikirlerinden çok etkilendiğini söylediği Alan Watts adlı hiper zekâlı bir işletim sistemiyle tanıştırır. Alan Watts, Zen düşüncesinin ve Taoculuğun Batı’da tanınmasına büyük katkılarda bulunmuş bir akademisyen ve düşünürdür. Dolayısıyla çalışmada, Watts’ın görüşlerinden hareketle Her’ün etik düşüncesinin ortaya koyulması amaçlanmış ve ilgili literatür taranarak, yöntem olarak felsefi eleştiri kullanılmıştır. Zen düşüncesine koşut olarak düşünür Watts, dünya ve yaşamın günlük düşünme alışkanlıklarının ötesine geçerek yeni bir bakış açısıyla görülebilmesi için evren ve diğer insanlardan ayrık, özerk varlıklar olduğumuza duyulan ego merkezli inançtan kurtulmamız gerektiğini öne sürmektedir. "Her"de öncelikle Samantha, sonrasında da Theodore, tam da Watts’un ileri sürdüğü gibi bir dönüşüm yaşarlar. Böylelikle Theodore, egosunun kabuğunu kırarak evrendeki bütünlüğü görmeye başlar. "Her"ün sonunda Zen düşüncesinde ‘satori’ adı verilen durum, yaşamı yeni baştan kurmanın ve yeniden düzenlemenin etik imkânı olarak belirmektedir.
Higher Grounds: Practical Guidelines for Forging Learning Pathways in Upper Primary Education

Published: May 2021

To address chronically low primary school completion rates and the disconnect between learners’ skills at the end of primary school and the skills learners need to thrive in secondary school identified in many low- and middle-income countries, more investment is needed to improve the quality of teaching and learning in upper primary grades. Accordingly, we provide guidelines for improving five components of upper primary education: (1) In-service teacher professional development and pre-service preparation to improve and enhance teacher quality; (2) a focus on mathematics, literacy, and core content-area subjects; (3) assessment for learning; (4) high-quality teaching and learning materials; and (5) positive school climates. We provide foundational guiding principles and recommendations for intervention design and implementation for each component. Additionally, we discuss and propose how to structure and design pre-service teacher preparation and in-service teacher training and ongoing support, fortified by materials design and assessment, to help teachers determine where learners are in developmental progressions, move learners towards mastery, and differentiate and support learners who have fallen behind. We provide additional suggestions for integrating a whole-school climate curriculum, social-emotional learning, and school-related gender-based violence prevention strategies to address the internal and societal changes learners often face as they enter upper primary.
TD 2630 - Contrabando de Agrotóxicos no Brasil: o perigo é real? Uma análise com base em laudos periciais de produtos apreendidos (2008-2018)
Authors: Moraes Rodrigo Fracalossi de
Published: May 2021

Entre 2007 e 2018 órgãos federais apreenderam, em vários pontos do país, cerca de 1,3 mil cargas de agrotóxicos contrabandeados ou com suspeita de serem falsificados/ adulterados. Estes produtos são apresentados frequentemente pela indústria como mais tóxicos do que os comercializados no mercado legal ou como falsificações ineficazes no combate a pragas, mas há pouca informação sistematizada sobre este tipo de crime. A partir de um banco de dados com 3.690 observações, construído a partir de laudos periciais com informações sobre agrotóxicos apreendidos por órgãos federais, foi feito um perfil deste tipo de crime no Brasil. Identificou-se que: i) o volume do contrabando de agrotóxicos é provavelmente pequeno quando comparado à dimensão do consumo deste tipo de produto no Brasil; ii) não há evidência de que produtos contrabandeados sejam mais tóxicos do que similares nacionais, embora possam ter um maior risco ambiental; iii) produtos contrabandeados raramente são falsos; iv) o contrabando é causado principalmente por diferenças de preço, e não pela proibição do uso de certos ingredientes ativos; v) agrotóxicos acondicionados em embalagens sem rótulo são mais tóxicos; vi) a principal origem dos produtos é a China, os quais comumente entram no Brasil pelo Paraguai e pelo Uruguai; vii) as apreensões tendem a crescer em períodos de pré-plantio ou plantio; e viii) há alguma evidência de que este tipo de crime é realizado por grupos organizados, mas em sua maior parte ele é do tipo “contrabando-formiga”. Estes dados indicam que não há evidência de que o contrabando de agrotóxicos traga riscos à saúde pública, saúde ocupacional ou ao meio ambiente significativamente superiores aos dos comercializados legalmente no país. Muito embora o contrabando deva, é claro, ser reprimido, é possível que este tema desempenhe sobretudo um papel simbólico. Em um contexto de mobilização de vários atores dentro e fora do Estado em prol de mais restrições ao uso de agrotóxicos e de ampliação na tributação para o setor, a ênfase no mercado ilegal contribui para associar a reputação de produtores e distribuidores de agrotóxicos no setor formal a comportamentos responsáveis e para expandir redes de relacionamento com integrantes do Estado.
