Download or read book Quality Control Methods for Medicinal Plant Materials written by World Health Organization and published by World Health Organization. This book was released on 1998 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: A collection of test procedures for assessing the identity, purity, and content of medicinal plant materials, including determination of pesticide residues, arsenic and heavy metals. Intended to assist national laboratories engaged in drug quality control, the manual responds to the growing use of medicinal plants, the special quality problems they pose, and the corresponding need for international guidance on reliable methods for quality control. Recommended procedures - whether involving visual inspection or the use of thin-layer chromatography for the qualitative determination of impurities - should also prove useful to the pharmaceutical industry and pharmacists working with these materials.
Download or read book Pesticides in the Diets of Infants and Children written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many of the pesticides applied to food crops in this country are present in foods and may pose risks to human health. Current regulations are intended to protect the health of the general population by controlling pesticide use. This book explores whether the present regulatory approaches adequately protect infants and children, who may differ from adults in susceptibility and in dietary exposures to pesticide residues. The committee focuses on four major areas: Susceptibility: Are children more susceptible or less susceptible than adults to the effects of dietary exposure to pesticides? Exposure: What foods do infants and children eat, and which pesticides and how much of them are present in those foods? Is the current information on consumption and residues adequate to estimate exposure? Toxicity: Are toxicity tests in laboratory animals adequate to predict toxicity in human infants and children? Do the extent and type of toxicity of some chemicals vary by species and by age? Assessing risk: How is dietary exposure to pesticide residues associated with response? How can laboratory data on lifetime exposures of animals be used to derive meaningful estimates of risk to children? Does risk accumulate more rapidly during the early years of life? This book will be of interest to policymakers, administrators of research in the public and private sectors, toxicologists, pediatricians and other health professionals, and the pesticide industry.
Download or read book Phytochemical Methods written by Jeffrey B. Harborne and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: While there are many books available on methods of organic and biochemical analysis, the majority are either primarily concerned with the application of a particular technique (e.g. paper chromatography) or have been written for an audience of chemists or for biochemists work ing mainly with animaltissues. Thus, no simple guide to modern metho ds of plant analysis exists and the purpose of the present volume is to fill this gap. It is primarily intended for students in the plant sciences, who have a botanical or a general biological background. It should also be of value to students in biochemistry, pharmacognosy, food science and 'natural products' organic chemistry. Most books on chromatography, while admirably covering the needs of research workers, tend to overwhelm the student with long lists of solvent systems and spray reagents that can be applied to each class of organic constituent. The intention here is to simplify the situation by listing only a few specially recommended techniques that have wide currency in phytochemical laboratories. Sufficient details are provided to allow the student to use the techniques for themselves and most sections contain some introductory practical experiments which can be used in classwork.

Download or read book Regulating Pesticides in Food written by National Research Council and published by National Academies Press. This book was released on 1987-02-01 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concern about health effects from exposure to pesticides in foods is growing as scientists learn more about the toxic properties of pesticides. The Delaney Clause, a provision of the Food, Drug and Cosmetic Act, prohibits tolerances for any pesticide that causes cancer in test animals or in humans if the pesticide concentrates in processed food or feeds. This volume examines the impacts of the Delaney Clause on agricultural innovation and on the public's dietary exposure to potentially carcinogenic pesticide residues. Four regulatory scenarios are described to illustrate the effects of varying approaches to managing oncogenic pesticide residues in food.

Available in PDF, EPUB and Kindle. Book excerpt: Policy Issues in Genetically Modified Crops: A Global Perspective contains both theoretical and empirical evidence of a broad range of aspects of GM crop policies throughout the world. Emphasizing world agriculture production and ethics of GM crops, the book balances insights into the various discussions around the use of GM crops including soil health, effects on animals, environmental sustainability impact, and ethical issues. The book presents aspects of GM crop policies and prevailing controversies throughout the world, in 5 sections containing 23 chapters. Beginning with the discussion of the policies related to GM crops, the book dives deep into issues related to food insecurity, agricultural sustainability, food safety, and environmental risks. Section 5 also captures the recent advances in agricultural biotechnology encompassing research trends, the nano-biotech approach to plant genetic engineering, and other transformation techniques in crop development. The contributors of the book represent different backgrounds, providing a holistic overview of diverse approaches and perspectives. Policy Issues in Genetically Modified Crops: A Global Perspective is a valuable resource for researchers in agricultural policy and economics, agricultural biotechnology, soil science, genetic engineering, ethics, environmental management, sustainable development, and NGOs. - Discusses ethics, varieties, research trends, success, and challenges of genetic modification - Addresses both crop production and potential health impacts - Includes extensive theoretical research and studies

Book excerpt: The global biodiversity and climate emergencies demand transformative changes to human activities. For example, food production relies on synthetic, industrial and non-sustainable products for managing pests, weeds and diseases of crops. Sustainable farming requires approaches to managing these agricultural constraints that are more environmentally benign and work with rather than against nature. Increasing pressure on synthetic products has reinvigorated efforts to identify alternative pest management options, including plant-based solutions that are environmentally benign and can be tailored to different farmers’ needs, from commercial to small holder and subsistence farming. Botanical insecticides and pesticidal plants can offer a novel, effective and more sustainable alternative to synthetic products for controlling pests, diseases and weeds. This Special Issue reviews and reports the latest developments in plant-based pesticides from identification of bioactive plant chemicals, mechanisms of activity and validation of their use in horticulture and disease vector control. Other work reports applications in rice weeds, combination biopesticides and how chemistry varies spatially and influences the effectiveness of botanicals in different locations. Three reviews assess wider questions around the potential of plant-based pest management to address the global challenges of new, invasive and established crop pests and as-yet underexploited pesticidal plants.
