This book was released on 2017 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: In highly urbanized areas, intensive use of pyrethroids has led to offsite transport to surface waters at concentrations known to cause toxicity to aquatic organisms. However, there is limited knowledge on the occurrence and distribution of pyrethroids in urban settings, or the role dust particles play in offsite transport of pyrethroids. Additionally, when pyrethroids enter the environment, they undergo transformation to form a common degradation product 3-phenoxybenzoic acid (3-PBA), which has been shown to cause endocrine disruption. However, little research has been conducted on the formation of 3-PBA in urban environments, its occurrence in urban streams, or its stability in different environmental matrices. Here we first evaluated the occurrence of particle-borne insecticides including pyrethroids in outdoor urban dust and studied their spatial and temporal distribution patterns and correlation with particle sizes. Temporally, particle-bound insecticides increased over the dry season and then significantly decreased after winter rains. Spatially, levels of pyrethroids in dust did not differ with distance from point of application, suggesting redistribution. Pyrethroids were found to associate predominantly with the smallest particle size fraction in dust. These findings suggest that loose particles are likely a significant source for offsite contamination of insecticides. In a subsequent study, we investigated pyrethroid transformation processes on concrete and 3-PBA formation. Pyrethroid degradation was rapid with hydrolysis being the most significant pathway, leading to rapid formation of 3-PBA. Low levels of 3-PBA were constantly detected in urban surface water, suggesting the need to understand chronic exposure and risk to aquatic species. In order to aid risk assessment of 3-PBA, in the last study we examined its stability in different environmental matrices. The half-life of 3-PBA in surface water and aerobic sediments was relatively short, while it was prolonged in soil and anaerobic sediments. These results further suggested that urban soil may be a source of 3-PBA to surface water or underlying groundwater, and due to the continuous input, additional research is needed to evaluate adverse effects on non-target organisms.

This book was released on 2010-01-06 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of chemistry and pharmaceutical sciences is an impressive success story. The products of chemical and pharmaceutical industries are present eve- where in our everyday life. They help to pursue the modern way of living and they contribute to our high standard of living and safety, mobility, communication te- nologies, food, health, textiles and drinking water treatment, among many others. These products are labeled under the categories: pharmaceuticals, pesticides, det- gents, fertilizers, dyes, paints, preservatives, food additives and personal care pr- ucts, to name a few. Within these categories, groups of chemicals with similar structures can be found. However, often groups of chemicals with very different structures belong to the same category. For a long time the production of chemicals and pharmaceuticals, their usage and application was connected with the heavy pollution of the environment and serious health effects. At the end of the last century, it was realised that the products of che- cal and pharmaceutical industries are presenting a new type of environmental pol- tion that may also pose a health risk to the consumer. Most chemicals are used in so-called open applications in excessive amounts e. g. for personal care, hygiene, plant protection, health and in textiles. In many cases such as scents, detergents, textile chemicals, surface disinfectants, pesticides and others it is unavoidable that these chemicals are released into the environment according to their intended use.

Download or read book Pesticides written by Hamir S Rathore and published by CRC Press. This book was released on 2019-12-22 with total page 659 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pesticides play an important role in controlling pests that carry diseases and threaten crop production. In recent years, however, there has been increased concern about the adverse impacts of pesticides and their degradation products on public health and the environment. A considerable amount of work is being done to develop nonchemical methods of pest control, but it is not yet feasible to dispense with the use of chemical pesticides. Pesticides: Evaluation of Environmental Pollution brings together, in a single volume, current knowledge on environmental pollution caused by pesticides. It helps readers evaluate the effects that pesticide residues have in all compartments of the environment. Featuring contributions by eminent scientists from around the world, the book gives an overview of the fate and transport of pesticides and their degradation in the environment. Detailing the sources, concentration, and hazards of residues, it examines their effects in humans, birds and mammals, fish, soil invertebrates, soil microflora, aquatic invertebrates, water, milk products, and more. The book also addresses endocrine-disrupting pesticides and explores biopesticides as alternatives to chemical pesticides. A review of data on the potential hazards of pesticides, this reference will be of interest to readers working in the areas of chemical crop protection and pollution management. It adds a balanced perspective to the debate between those who think that pesticides should be banned and those who consider the continued use of large quantities to be necessary for the survival of humanity.

This is linked to FAO’s strategic objectives, especially SO1, SO2, SO4 and SO5 because of the crucial role of soils to ensure effective nutrient cycling to produce nutritious and safe food, reduce atmospheric CO2 and N2O concentrations and thus mitigate climate change, develop sustainable soil management practices that enhance agricultural resilience to extreme climate events by reducing soil degradation processes. This document will be a reference material for those interested in learning more about sources and effects of soil pollution.
Download or read book International Code of Conduct on Pesticide Management written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2023-04-29 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this guidance on fulfilling the reporting requirements of Article 12 of the Code of Conduct is to obtain a regular flow of information on its observance to strengthen implementation of the Code, to provide data for its future revisions and improvement, and, most importantly, to improve the protection of human health and the environment related to pesticide use and management in agriculture and public health. The guidance was prepared in compliance with the FAO/WHO International Code of Conduct on Pesticide Management, which sets out a framework and voluntary standards of conduct for stakeholders in pesticide management, in particular governments and the pesticide industry. Endorsed by FAO, WHO, governments, pesticide producers, non-governmental organizations and other stakeholders, the Code outlines their shared responsibility to promote best practice and risk reduction throughout the pesticide life cycle. The Code of Conduct thereby establishes the commitment and moral obligation of stakeholders to comply with the agreed standards of conduct and to assume their respective responsibilities. These include governments’ responsibility to promote pesticide risk reduction and the industry’s responsibility to produce products that are adapted to the context of their use and to provide stewardship of those products throughout their life cycle. This guidance was prepared with the support of the FAO/WHO Joint Meeting on Pesticide Management (JMPM) to provide further guidance on the provisions of the Code of Conduct related to its observance and implementation. It reflects the joint FAO/WHO approach to pesticide management, thus addressing the topic in both agricultural and public health settings.
