Book Synopsis Test No. 509: Crop Field Trial by : Organisation for Economic Co-operation and Development
Download or read book Test No. 509: Crop Field Trial written by Organisation for Economic Co-operation and Development and published by . This book was released on 2009 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crop field trials are conducted to determine the magnitude of the pesticide residue in or on raw agricultural commodities, including feed items, and should be designed to reflect pesticide use patterns that lead to the highest possible residues. Objectives of crop field trials are to: (1)quantify the expected range of residue(s) in crop commodities following treatment according to the proposed or established good agricultural practice; (2)determine, when appropriate, the rate of decline of the residue(s) of plant protection product(s) on commodities of interest; (3)determine residue values such as the "Supervised Trial Median Residue" and "Highest Residue" for conducting dietary risk assessment; and (4)derive maximum residue limits (MRLs). This Test Guideline requires one sample from treated plots at each sampling interval for crops that have eight or more crop field trials. The test substance(s) should be stored under appropriate conditions for the study duration and applied soon after preparation or mixing. Test substance applications should not be made in strong wind, during rain or when rainfall is expected shortly after application. For all applications, the application rate should be expressed in terms of amount of product and/or active ingredient per unit area. At the end of each crop field trial, the (stored) samples are analysed for residue level (expressed for example in mg/kg).

Book Synopsis Human and Ecological Risk Assessment by : Dennis J. Paustenbach
Download or read book Human and Ecological Risk Assessment written by Dennis J. Paustenbach and published by John Wiley & Sons. This book was released on 2024-04-15 with total page 1319 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understand the fundamentals of human risk assessment with this introduction and reference Human risk assessments are a precondition for virtually all industrial action or environmental regulation, all the more essential in a world where chemical and environmental hazards are becoming more abundant. These documents catalog potential environmental, toxicological, ecological, or other harms resulting from a particular hazard, from chemical spills to construction projects to dangerous workplaces. They turn on a number of variables, of which the most significant is the degree of human exposure to the hazardous agent or process. Human and Ecological Risk Assessment combines the virtues of a textbook and reference work to introduce and analyze these vital documents. Beginning with the foundational theory of human health risk assessment, it then supplies case studies and detailed analysis illustrating the practice of producing risk assessment documents. Fully updated and authored by leading authorities in the field, the result is an indispensable work. Readers of the second edition of Human and Ecological Risk Assessment will also find: Over 40 entirely new case studies reflecting the latest in risk assessment practice Detailed discussion of hazards including air emissions, contaminated food and soil, hazardous waste sites, and many more Case studies from multiple countries to reflect diverse international standards Human and Ecological Risk Assessment is ideal for professionals and advanced graduate students in toxicology, industrial hygiene, occupational medicine, environmental science, and all related subjects.
Book Synopsis Recent advancements in microbe-pesticide interaction: A smart-soil bioremediation approach, 2nd edition by : Pankaj Bhatt
Download or read book Recent advancements in microbe-pesticide interaction: A smart-soil bioremediation approach, 2nd edition written by Pankaj Bhatt and published by Frontiers Media SA. This book was released on 2024-06-19 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing use and the continuous development of pesticides are required to maintain sufficient global food production. The pesticide residues and their biotic and abiotic breakdown products may be harmful to the environment and may leach into waterways, thus it is crucial that the interactions of pesticides with microorganisms are deeply understood at all levels. Pesticides reach the soil via direct and indirect routes. The fate of the pesticides in the soil is affected by chemical, physical and microbiological factors. Microbial degradation of pesticides in soil is possible owing to the diverse metabolic capabilities of the microorganisms present, thus indigenous microbes act as biocatalysts for the remediation of the pesticides from the environment. The research topic will cover novel insights into microbial pesticide degradation with specific attention to the microbe-pesticide interactions in soil. To date researchers have focused on the degradation of pesticides using indigenous microbes with different degradation rate. There is scant information about the degradation intermediates, metabolic pathways, enzymes and complete set of factors involved into the microbes inhabiting into the pesticides contaminated soil. Therefore this Research Topic aims to contribute to the understanding of the role of microbes in pesticide degradation in soil. Since pesticide exposure may result in stress responses in the microbial population of the soil, there is also a need to know about the impact of pesticides on the microbial cell structure, membrane transporters, cellular content, metabolic pathways and gene expression. We are interested in reports of novel metabolic pathways, expression of the key genes in response to pesticide exposure and the changes in microbial physiology caused by pesticide exposure. The removal of the pesticides from the soil requires smart microbial methods that can reduce the pesticides concentration in a short time. The development of the smart bioremediation methods includes the direct application of the potential screened microbial strains and their enzymes. The immobilized microbial strains and their enzymes can be used for the rapid removal of the toxic pesticides from the soil environment. In addition, engineering of the microbial consortia can be developed as the potential smart bioremediation tool. Papers on single isolates or microbial communities are welcome as are reports of novel genes, enzymes or metabolites that might be used as markers of soil contamination. We would especially welcome manuscripts describing the application and development of smart soil bioremediation approaches that could be beneficial for the treatment of large scale contaminated agricultural and industrial soils. The research topic is of immediate interest to scientists and policy-makers and Frontiers in Microbiology is an ideal forum for a collection of novel, high-impact reports. The following themes are welcomes but not limited to: • Novel advancements into the microbe-pesticide interactions to clean the pesticide contaminated soil • High throughput screening of the potential bacterial, fungi and algae strains for the removal of pesticides from the contaminated soil • Smart soil bioremediation using indigenous microbial cultures and their purified enzymes • Microbial enzymes a smart tool for bioremediation of the soil • Engineering of the microbial consortia for the complete pesticides removal and resource recovery
