Resumen

Abstract The multiresidue method used in this study allows the determination of 101 pesticides, including organophosphorus, organochlorine, and nitrogen-containing pesticides, in crops by gas chromatography with mass selective detector. Analysis was performed in the selected–ion monitoring mode, and the identities of the positive analytes were confirmed by retention time and the ratios of selected ions. The selected ion mode demonstrated an acceptable selectivity for most of the pesticides determined in 3 kinds of samples (Chrysanthemum coronarium; Perilla japonica, leaf; and Lactuca savita, which are very popular vegetables eaten raw in Korea), and very minor interferences were observed in the elution area of the pesticide analytes. Samples were spiked with pesticides at 0.1–1.0 mg/kg. The recoveries of 90% of the pesticides were between 70 and 110%; however, the recoveries of acephate and folpet were very poor, i.e., <50%. The limits of detection (LODs) for most pesticides were between 0.02 and 0.3 mg/kg, and the LODs for about half of the pesticeds studied were <0.05 mg/kg.

Resumen

Abstract Pesticides are the main remedy for pest eradication, but their use has been found to be harmful also to various non-target organisms. In this study, giant cell formation was observed in hepatocytes of experimental albino rats following two type II pyrethroid pesticdes, Cypermethrin and Beta-cyfluthrin. Histopathological examination was done for this purpose and the results revealed the formation of giant cells and polyploidy condition following intoxication of these experimental compounds with Beta-cyfluthrin, with an edge over, and Cypermethrin, probably due to structural differences.

Resumen

Pesticides are derived from the Greek word pestis - pest, cido - to destroy, and are substances used to exterminate, repel or reduce plant pests or to act as plant growth regulators, as well as nitrogen stabilizers, plant defoliants, or desiccants. Pesticides are primarily used in agriculture, but about half of the 200 pesticides registered today are widely used by non-agricultural organizations such as hospitals, restaurants, and decontamination services. Pesticide misuse is a big problem not only in Mongolia but all over the world. When this toxic chemical is sprayed on crops, plants, and soil, it accumulates and is released back into the living organism through soil, air, and atmospheric degradation, resulting in poisoning and sickness.Pesticide levels in vegetables and food brought into Mongolia must be kept under strict monitoring.Furthermore, assessments of the types and applications of imported pesticides, as well as their residues in food, reveal the need for further detailed research into pesticide exposure and its negative consequences on human health in Mongolia.

Resumen

The plague bacillusYersinia pestisis unique among the pathogenicEnterobacteriaceaein utilizing an arthropod-borne transmission route. Transmission by fleabite is a recent evolutionary adaptation that followed the divergence ofY. pestisfrom the closely related food- and waterborne enteric pathogenYersinia pseudotuberculosis. A combination of population genetics, comparative genomics, and investigations ofYersinia-flea interactions have disclosed the important steps in the evolution and emergence ofY. pestisas a flea-borne pathogen. Only a few genetic changes, representing both gene gain by lateral transfer and gene loss by loss-of-function mutation (pseudogenization), were fundamental to this process. The emergence ofY. pestisfits evolutionary theories that emphasize ecological opportunity in adaptive diversification and rapid emergence of new species.

Resumen

Sari. Pestisida banyak digunakan petani untuk mencegah hama pada proses penanaman daun teh, padahal jika tertelan manusia bisa menimbulkan banyak penyakit. Kita perlu mempelajari metode yang mudah untuk mendeteksi kandungan pestisida. Pada penelitian ini, pestisida deltamethrin pada daun teh dideteksi dengan menggunakan alat spektroskopi Raman. Daun teh segar disemprot pestisida dengan konsentrasi 0,01 ppm; 0,1 ppm; 1 ppm; 10 ppm; dan 100 ppm. Variasi penyemprotan juga dilakukan pada daun teh, yaitu 3x dan 6x penyemprotan untuk setiap konsentrasi pestisida yang digunakan. Daun teh yang sudah disemprot kemudian dikeringkan dan ditaruh di dudukan sampel di alat spektroskopi raman dengan sumber laser yang dipakai adalah 532 nm. Spektroskopi Raman membantu dalam menentukan nilai deteksi pestisida pada daun teh dimana nilai deteksi pestisida berupa perbandingan antara panjang gelombang (Raman shift) dengan intensitas. Tujuan penelitian ini adalah untuk mengetahui nilai deteksi pestida yang disemprot pada daun teh dan menentukan pengaruh variasi jumlah semprotan pestisida ke daun teh. Hasil penelitian menunjukkan bahwa pestisida deltamethrin pada daun teh berhasil dideteksi dengan menggunakan alat spektroskopi Raman. Pada penyemprotan 6x puncak deltamethrin menunjukkan intensitas yang lebih tinggi dibandingkan dengan intensitas puncak pestisida deltamethrin dengan kondisi penyemprotan 3x pada daun teh.Kata kunci: Pestisida Deltamethrin ∙ Spektroskopi raman ∙ Teh Detection of Deltamethrin pesticide on tea leaves with different spray variations (3x and 6x) using spektroskopi raman Abstract. Pesticide were widely used by farmers to prevent pests on tea plant , whereas if swallowed by human could cause many diseases. We need to know the easy method to detect deltamethrin pesticide. In this experiment, deltamethrin pesticides in the tea leaves were detected using Raman spectroscopy. The fresh tea leaves were sprayed with pesticides at the concentration of 0.01 ppm, 0.1 ppm, 1 ppm, 10 ppm, and 100 ppm. Spraying concentration were also carried out on the tea leaves with 3 and 6times spray variation for each concentration. The sprayed tea leaves were dried and placed in a sample position at the Raman spectroscopy. Its testing tool helped in determining the detection value of pesticides on tea leaves, the value of detection of pesticides in the form of a ratio between wavelength (Raman shift) with intensity. The purpose of this study was to determine the detection value of pesticides sprayed on tea leaves and determine the effect of variations in the amount of pesticide spray to tea leaves. The results showed that the deltamethrin pesticide on tea leaves was successfully detected using the Raman spectroscopy. In spraying 6 times, the peak of deltamethrin showed a higher intensity compared to the peak intensity of the pesticide deltamethrin with spraying conditions 3 times on the tea leaves.Keywords: Deltamethrin pesticides ∙ Raman spectroscopy ∙ Tea leaves

Resumen

Many pathogens usurp the host hemostatic system during infection to promote pathogenesis.Yersinia pestis, the causative agent of plague, expresses the plasminogen activator protease Pla, which has been shownin vitroto target and cleave multiple proteins within the fibrinolytic pathway, including the plasmin inhibitor α2-antiplasmin (A2AP). It is not known, however, if Pla inactivates A2APin vivo; the role of A2AP during respiratoryY. pestisinfection is not known either. Here, we show thatY. pestisdoes not appreciably cleave A2AP in a Pla-dependent manner in the lungs during experimental pneumonic plague. Furthermore, following intranasal infection withY. pestis, A2AP-deficient mice exhibit no difference in survival time, bacterial burden in the lungs, or dissemination from wild-type mice. Instead, we found that in the absence of Pla, A2AP contributes to the control of the pulmonary inflammatory response during infection by reducing neutrophil recruitment and cytokine production, resulting in altered immunopathology of the lungs compared to A2AP-deficient mice. Thus, our data demonstrate that A2AP is not significantly affected by the Pla protease during pneumonic plague, and although A2AP participates in immune modulation in the lungs, it has limited impact on the course or ultimate outcome of the infection.

Resumen

DMT2 is the most common type of diabetes in the world. In developed countries, dia¬betes affects people over 65 years old. However, in Asia, the younger generation is also affected and the age onset of diabetes has declined. Several factors that may lead to early diabetes is changes in consumption and activity patterns. However, that should be noted that pestisides expusure by food and environmental pollutants can even be the reason behind the increasing incidence of type-2 diabetes mellitus. This study aims to provide a systematic review of the impact of pesticide exposure on the incidence of type-2 diabetes, especially at a young age. We performed articles search using Science Direct, Spinger Link, ProQuest, Pubmed and Scopus databases published since 2010 until 2020. In total, 10 scientific articles included in this study. Pesticide exposure is determined by the nature of the sources. Most studies showed a strong association between organochlorine pesticides and also the incidence of diabetes. The average age of the entire study was 43 years this has proven that there is a decrease in the onset of age of people with DMT2 in Asia. The results show that organochlorine pesticides had an impact on the incidence of DMT2 at a younger age. Someone with high levels of organochlorines serum will had a high blood glucose levels. Race may also effect the incidence of diabetes, it need to be assessed experimentally.

Resumen

La notion d’itinéraire technique est une notion agronomique qui nous permet d’appréhender l’imbrication entre les rendements objectifs et les niveaux d’utilisation d’intrants associés. Dès lors, on peut admettre qu’à différents types d’itinéraires techniques correspondent différentes fonctions de production. Modéliser ces différentes fonctions est une des clés pour mieux comprendre la dépendance de certaines pratiques culturales aux pesticides et de ce fait constitue un enjeu majeur pour concevoir les futures politiques publiques.Intégrer cette notion d’itinéraire technique nécessite de tenir compte de l’interdépendance entre les choix de ces pratiques, leur rendement et les utilisations associées. Pour ce faire, on considère des modèles de changement de régime endogène qui permettent de contrôler des biais de sélection. Lorsque ces pratiques sont inobservées, on définit la séquence de choix comme processus Markovien.Le modèle résultant nous permet de recouvrir les pratiques culturales, leurs niveaux de rendement et d’utilisation d’intrants ainsi que la dynamique de choix des dites pratiques. Lorsque ces pratiques sont observées, on décide de considérer un modèle primal afin de pouvoir vérifier le rôle différencié des pesticides et évaluer l’effet des politiques publiques conjointement sur les rendements et les niveaux d’utilisation d’intrants chimiques.En bref, cette thèse vise à donner des outils pour évaluer au mieux les effets des politiques agro-environnementales sur les utilisations de pesticides, les rendements et mes choix de pratiques culturales des agriculteurs
Cropping management practices is an agronomic notion grasping the interdependence between targeted yield and input use levels. Subsequently, one can legitimately assume that different cropping management practices are associated to different production functions. To better understand pesticide dependence – a key point to encourage more sustainable practices – one have to consider modelling cropping management practices specific production functions.Because of the inherent interdependence between those practices and their associeted yield and input use levels, we need to consider endogenous regime switching models.When unobserved, the sequence of cropping management practices choices is considered as a Markovian process. From this modelling framework we can derive the cropping management choices, their dynamics, their associated yield and input use levels. When observed, we consider primal production functions to see how yield responds differently to input uses based on the different cropping management practices. Thus, we can assess jointly the effect of a public policy on input use and yield levels.In a nutshell, in this PhD we are aiming at giving some tools to evaluate the differentiated effect of agri-environmental public policies on production choies and on the associated yield and input use levels

Resumen

La photodégradation de l'imazapyr et de l'imazamox, deux herbicides de la famille des imidazolinones, a été étudiée en solution aqueuse sous rayonnement UV. Les résultats obtenus ont permis de proposer des schémas de dégradation de ces herbicides. Les cinétiques de dégradation des pesticides d'une part, d'apparition et de disparition des principaux photoproduits d'autre part, ont été suivies par chromatographie liquide couplée à un détecteur à barrettes de diodes (LC-DAD). Après une étape de pré-concentration sur phase solide (SPE), la caractérisation des photoproduits a été réalisée par chromatographie liquide couplée à un spectromètre de masse (LC-MS) et par spectrométrie de masse haute résolution (HRMS). Les pesticides sont stables à l'obscurité mais se dégradent sous irradiation selon une cinétique de premier ordre, l'imazamox étant deux fois plus stable que l'imazapyr. Ces pesticides conduisent en présence d'ions métalliques à des interactions de complexation fortes de type chélate. Une structure cristalline entre l'imazapyr et le cuivre [Cu(Himz)2(H2O)2] a été mise en évidence par diffraction X. Une étude chimiométrique a permis d'évaluer l'influence sur la dégradation de cations métalliques tels que le cuivre ou le calcium, d'anions associés tels que les ions nitrate ou chlorure, et du rapport molaire pesticide/ion métallique, ainsi que les éventuelles interactions entre ces paramètres. Les cinétiques de dégradation et d'apparition des pesticides et des principaux photoproduits sont ralenties en présence d'ions métalliques (Cu2+ > Ca2+). En effet, la complexation tend à stabiliser les molécules. Au contraire, la présence d'ions nitrate augmente la dégradation par suite de formation de radicaux hydroxyle sous irradiation UV

Resumen

Armyworm (Spodoptera frugiperda) is a pest on several food crops including soybeans and corn. Armyworm control still emphasizes the use of resistant varieties and insecticides. Alternative efforts are needed to use more environmentally-friendly control methods, including the use of organic pesticides from biological materials. The control of Spodoptera frugiperda was carried out by testing the application of several types of organic pesticides at the same concentration of 50%. The purpose of this study was to determine the type of pesticide that was most effective in reducing mortality and attack from Spodoptera frugiperda. The study was started by doing mass propagation of S. frugiperda larvae, S. frugiperda larvae investment, and mortality test. The test used the Randomized Block Design (RBD) method using several organic pesticides consisting of five treatments, namely P0 (control), P1 (tobacco), P2 (shallot), P3 (garlic), and P4 (papaya leaves), P5 (blimbing wuluh leaves), P6 (Jatropa curcas fruit), P7 (lemongrass). The results of the application of organic pesticides on the mortality and attack rate of S. frugiperda had a significant effect. Organic pesticides that are most effective in reducing the mortality and attack rates of S. frugiperda are pesticides made from tobacco (Nicotiana tabacum). At a concentration of 50% organic pesticides made from tobacco can reduce the mortality of S. frugiperda up to 100%. Tobacco-based pesticides also received the lowest land attack rate at 46%. Organic pesticides applied to S. frugiperda larvae also affect the growth of S. frugiperda pupae.

Resumen

In production experiments carried out in the crops of winter wheat of two varieties Iziuminka and Stanichnaya at the FSUE Kalininskoye enterprise in the Volgograd region, it was found that a decrease in weediness of crops and the number of pests as a result of the use of pesticides contributed to an increase in the yield of the variety Izuminka by 7 centners / ha, variety Stanichnaya on 4 c / ha. The use of pesticides also affected the gluten content in grains, its amount increased from 33% to 36% in the Stanichnaya variety and from 30% to 34.5% in the Iziuminka variety. A varietal reaction to the use of pesticides was revealed. Variety Izuminka showed greater sensitivity to the improvement of the phytosanitary situation as a result of the use of pesticides than variety Stanichnaya.

Resumen

Pesticides are used in intensive farming to help fight plant pests and diseases (insecticides, fungicides), kill weeds (herbicides), as well as accelerate the growth of seeds (defoliants), but until 1992 pesticides were kept in improperly equipped warehouses, there was no maintenance or accounting of the pesticides. Consequently, the environment of the warehouse was often polluted. Such sources of pollution are hazardous to the environment. Economic activities in the area have been carried out from 1980 to 1994. Various agricultural chemicals have been stored and used there. Later, in 1997, chemicals (fertilizers and plant protection chemicals) stored in the territory of the warehouse have been collected and removed from the territory. During the inventory of 2009, no chemical substances were found in the territory. In 2010, an investigation carried out in the territory of the pesticide warehouse revealed unacceptable levels of pollution in the soil and the groundwater by pesticides and other toxic and neutral chemicals. In 2012, the polluted territory was cleaned eliminating the remains of buildings, and removing the soil polluted by the pesticides. The aim of the study was to evaluate the impact of the territory of the former pesticide warehouse in Kaunas District Municipality, Bubių Village on the groundwater during the period from 2012 to 2016. The results have shown that the groundwater is mostly polluted with nitrogen compounds, as well as the tendency in increase of chlorides, sodium, and calcium. Minimum and unchanging concentrations of the pesticides (DDD, DDE, DDT) were determined throughout the investigation.

Resumen

The purpose of the research was to investigate pesticide residues in bee’s body and to identify the most common and dangerous pesticides that can affect honeybees in the forest site. The bee samples have been analyzed to the residues of 11 most widely used pesticides. As a result of the research, it was established that most of the studied pesticides (72.7%) wasn’t registered in the bee samples, collected from the apiary, stationed in the forest site. In 20% of the analyzed bee samples no residues of either of the 11 investigated pesticides were found, in 40% of the bee samples, detectable level of residues of a single pesticide (the pyrethroidic insecticide Tau-fluvalinate) was recorded, in other 20% of the samples detectable residues of 2 pesticides (the neonicotinoid insecticide Imidacloprid and acaricide Amitraz) was recorded, and in the other 20% of the bees samples detectable residues of 3 pesticides (pyrethroid insecticide Tau-fluvalinate, insecticide neonicotinoid Imidacloprid and acaricide Amitraz) was registered. The values of detectable concentrations of pesticide residues recorded in bee samples taken from the forest site were very small, constituting on average: the pyrethroid insecticide Tau-fluvalinate – 0.0062±0.0007 mg/kg; the neonicotinoid insecticide Imidacloprid – 0.0060±0.0006 mg/kg and the acaricide Amitraz – 0.0058±0,0006 mg/kg. The detected concentrations of pesticide residues are 1.7 - 32.2 times lower than the maximum admisibile limits, according to national and EU standards. Hence, the forest site environment is not polluted with pesticide residues and, therefore, doesn’t represent any risk of contamination for bee families, which could compromise the bee’s health and the safety of apiculture products, intended for human consumption.

Resumen

Pesticides are substances widely used in agriculture, which are the cause of acute poisoning in a significant percentage worldwide. The aim of this paper is to analyze cases of pesticide poisoning during 2020, according to the data of the Toxicology Laboratory of the Institute of Forensic Medicine in Nis. Pesticide poisoning has been proven in 18 cases (8.11% of all cases). Organophosphate pesticides were detected in nine cases, glyphosate in five, pendimethalin in two, while metolachlor and piperonyl butoxide were detected in one case each. Data on cases of poisoning indicate that education on the proper use of pesticides is necessary in order to reduce the number of acute and chronic poisonings.

Resumen

Copper-based pesticides have been used around the world for more than 200 years to control bacterial and fungal diseases in a variety of crops. In our review, we found that copper content from cupric fungicides in vineyard soil surface horizons often exceeds 200 mg/kg. However, there are few studies on copper content in vineyard soils in Russia. The fact of the matter is that soil microorganisms have greater metal sensitivity than plants. Therefore, the use of copper-based pesticides may damage microbial communities in vineyard soils and disrupt litter decomposition processes, thus leading to a long-term deterioration of ecological attributes and agricultural value of soils. It is this fact that makes the need for constant monitoring and assessment of the impact of copper-based pesticides on vineyard soils in Russia so paramount.

Resumen

Based on the analysis of statistical yearbooks "state of contamination of soils and objects of the natural environment of the Russian Federation with pesticides and toxicants of industrial origin", analysis of the incidence of workers and the population from exposure to residual pesticides and heavy metals, the need to assess soil contamination for organic farming purposes in accordance with the requirements of article 9 of the Federal law of 03.08.2018 No. 280-FZ "on organic products and amendments to certain legislative acts of the Russian Federation"is justified. For evaluation, a digital technology is proposed in the management of environmental safety and labor protection in agriculture, developed by scientists of the ITOSH-branch of the FGBNU FNAC VIM. It is proposed to solve the problems of detoxification of soils contaminated with heavy metals and residual pesticides identified during the assessment using the available domestic and foreign experience by various methods: physical, physical-chemical, and biological.

Resumen

The objective of this collaborative research project was to determine the factors that may cause enhanced pesticide transport under effluent irrigation. For s-triazines, the potential for enhanced transport through association with effluent dissolved organic matter (OM) was shown to be small in batch and column studies and in numerical simulations. High alkalinity and pH of treated effluents increased soil-solution pH for selected soil-effluent combinations, promoting the dissolution of soil OM and mobilizing otherwise OM-retained pesticides. Evapotranspiration in column studies resulted in increased pore-water concentrations of dissolved OM and some pesticide transport enhancement with the greatest effect observed with OM-poor soils. For ionogenic pesticides, effluent-induced increases in soil-solution pH increased the mobility of pesticides with acid dissociation constants within 2 pH units of the initial soil-solution pH. Effluents high in suspended solids and/or monovalent cations resulted in blockage of soil pores reducing water-flow velocity and/or changing flow paths. Reduced flow resulted in an increase in desorption time of soil sorbed pesticides, increasing the amount available for further transport with the net effect being soil texture dependent. In terms of pesticide degradation in soils, effluents appeared to have only a minor effect for the few pesticides investigated.
