Abstract:

The World Health Organization classified carbaryl, glyphosate, and paraquat as hazardous to human health. In the Agriculture Health Study in the United States, health problems were associated with the use of these 3 agrochemicals 12 or more times per year. These 3 agrochemicals were commonly used in Grenada. The purpose of this quantitative cross-sectional study was to investigate the relationship between the social and economic characteristics of the farmers who participated in the 2012 agriculture survey and the use of agrochemicals at frequencies that could pose health risks.

Abstract:

The global human population is expected to exceed 9 billion individuals by 2050, putting greater strain on the natural resources needed to sustain such a population. To feed this many people, some expect agricultural production will have to double and agrochemical use will have to increase anywhere from two- to five-fold relative to the turn of the century. Although industrial agriculture has provided many benefits to society, it has caused declines in biodiversity, both directly (e.g., through conversion of habitat) and indirectly (e.g., through contamination of adjacent natural habitats).

Abstract:

Traceability through all the stakeholders in food production is an issue of increasing importance, being specifically required by the regulations for food safety and quality (EC 178/2002), and for compliance with environmental protection. The agricultural market perceives a need for systems and technologies to automate the currently manual process of producing records of agrochemical inputs loaded into a spraying machine. A novel prototype Automated Agrochemical Traceability System (AACTS) to identify and weigh agrochemicals as they are loaded into crop sprayer has been designed, constructed,

Agrochemical use has been increasing in both developing and the developed nations. The unsafe handling and use of agrochemicals can lead to accumulation of hazardous chemicals in the body, causing adverse effects on health. This quantitative cross sectional study sought to understand the level of awareness, practices, and perceptions of safe chemical handling by agrochemical using the Theory of Planned Behavior. This study was conducted among 260 farmers in Plateau State, Nigeria. Data on background knowledge and practices of safe agrochemical handling by farmers were collected using a structu

Abstract:

The goal of this thesis is to analyze the emerging trends in the cross-border agrochemical distributors' network in Central and Eastern Europe. It aims to answer three research hypotheses and uses desk research methodology to reach this goal. The thesis studies five distributors of agrochemicals considered as pioneers in the industry and assumes their behavior as a proxy for the whole industry behavior. It verifies the first hypothesis that there is an ongoing cross-border consolidation of the distribution network. On the other hand, due to the industry stage and the agrochemicals' market grow

The relatively new separation technique of capillary electrophoresis, with its ability to provide rapid, high resolution separations based on electrophoretic mobility differences, has developed enormously over the last decade.

The objectives of these studies were to conduct further investigations into the interfacing of capillary electrophoresis with mass spectrometry via atmospheric-pr

Abstract:

Agrochemicals and pesticides are compounds of significant industrial and commercial importance. Over recent years, legislation has increased greatly and with this increased regulation, the necessity for trace impurity analysis of pesticides has grown. Modem chromatographic techniques with both UV and mass spectrometric detection have been used in the study of pesticidal compounds to separate and characterise impurities present at low levels. The use of these techniques is evaluated and suggestions for future work are outlined. The use and analysis of the pesticidal study compounds are reviewed

Abstract:

The overuse of agrochemicals by arable crop farmers in Guyana is of increasing concern. But the literature reveals a paucity of information concerning the reasons for farmers‟ persistence of this inappropriate practice. No previous study has been conducted using a structured format to reveal the scope or reasons for farmers‟ sustained overuse of these chemicals. This research adopted an original structured-type approach, suitable for unearthing and explaining the reasons for this phenomenon. The study was theoretically and analytically guided by the theory of practices and critical realist the

Abstract:

Currently, the increase of food demand of a steadily growing human population is not balanced by a global agricultural supply. As a consequence, crop protection plays a crucial role in maximising crop productivity and preventing losses caused by biological and not biological agents. Biological agents, collectively named as pests, are responsible for quantitative losses ranging from 20 % to 40 %, and qualitative losses, thus reducing the value of crops. For these reasons, new methods to control pests must be developed.The discovery of new agrochemicals is necessary to face the problem of the em

Abstract:

In agricultural watersheds, streams are intimately connected with croplands and may be inadvertently exposed to agrochemicals such as fertilizers and herbicides. Riparian plants and aquatic primary producers (aquatic plants, phytoplankton and periphyton) may be particularly affected by agrochemicals due to their taxonomic similarity to the intended targets (crop and weed species). The overall objective of this thesis was to assess the effects of fertilizers and the herbicide atrazine on riparian plants and aquatic primary producers. Effects were assessed across varying scales of observation

In recent years, the Mekong delta has been strongly developed both for agriculture and aquaculture.

Specifically, the large amount of pesticides imported and used in the Mekong delta not only help agriculture purposes but can also easily enter aquatic systems and affect aquaculture. Pesticides can be transported in the environment by chemo-dynamic procedures and hydrological processes. As a result, pesticides used in agriculture become dispersed and their residues

In order to do so, we conducted an exploratory research and made use of a bibliographical study as an instrument for the review of the pertinent literature, which incl

Abstract:

Rainfastness is the ability of agrochemical deposits to resist wash-off by rain and other related environmental phenomena. This work reports studies of the rainfastness of selected water-soluble polymers, including poly(vinyl alcohol) (PVA) and chitosan, on Vicia faba leaf surfaces. This was achieved using a novel method involving fluorescent microscopy combined with image analysis. The retention of polymer deposits was analysed via lab-scale washing to simulate rain. PVA over a threshold molecular weight and chitosan were shown to be excellent rainfastness aids. The washing method was ̳scaled

Abstract:

The world's population is expected to grow from 6 billion to about 10 billion by 2050. The greatest population increase is expected to occur in Africa, Latin America, and Asia. To feed a world with huge increases in population and to sustain the well-being of humans, a large increase in food production must be achieved. The projected increase in food production must be accomplished on the existing cultivated areas because the expansion of new land is limited by environmental concerns, urbanization and increasing water scarcity. Different compounds have been developed for the "immunization" of

<p>There are great problems of pesticide poisonings in the rural parts of the developing countries. Although these countries only use 25 percent of the world’s pesticide production they suffer from 99 percent of the deaths due to pesticide poisoning.</p><p>The study took place in Tarapoto, Peru, where immense quantities of pesticides are used in their extensive cultivations of rice. The highly toxic pesticides are applied with backpack sprayers without using any safeguard.</p><p>The objective of the study is to find out if the unsafe use of pesticides in Tarapoto is a result of insufficient in
