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.

Download or read book The Seine River Basin written by Nicolas Flipo and published by Springer Nature. This book was released on 2021-01-30 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book reviews the water-agro-food and socio-eco-system of the Seine River basin (76,000 km2), and offers a historical perspective on the river’s long-term contamination. The Seine basin is inhabited by circa 17 million people and is impacted by intensive agricultural practices and industrial activities. These pressures have gradually affected its hydrological, chemical and ecological functioning, leading to a maximum chemical degradation between the 1960s and the 1990s. Over the last three decades, while major water-quality improvements have been observed, new issues (e.g. endocrine disruptors, microplastics) have also emerged. The state of the Seine River network, from the headwaters to estuary, is increasingly controlled by the balance between pressures and social responses. This socio-ecosystem provides a unique example of the functioning of a territory under heavy anthropogenic pressure during the Anthropocene era. The achievements made were possible due to the long-term PIREN Seine research program, established in 1989 and today part of the French socio-ecological research network “Zones Ateliers”, itself part of the international Long-term Socio-economic and Ecological Research Network (LTSER). Written by experts in the field, the book provides an introduction to the water budget and the territorial metabolism of the Seine basin, and studies the trajectories and impact of various pollutants in the Seine River. It offers insights into the ecological functioning, the integration of agricultural practices, the analysis of aquatic organic matter, and the evolution of fish assemblages in the Seine basin, and also presents research perspectives and approaches to improve the water quality of the Seine River. Given its scope, it will appeal to environmental managers, scientists and policymakers interested in the long-term contamination of the Seine River.

Download or read book Urban Stormwater Management in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-03-17 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.
Download or read book PAHs written by Peter E. T. Douben and published by John Wiley & Sons. This book was released on 2003-07-25 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polycyclic aromatic hydrocarbons (PAHs), or polyarenes, are one of the largest and most structurally diverse class of organic molecules known. High percentages of polyarenes, representing a wide range of molecular sizes and structural types, are present in coal tars and petroleum residues. The major sources of PAHs are crude oil, coal and oil shale. The fuels produced from these fossil sources constitute the primary source of energy for the industrial nations of the world, and the petrochemicals from these raw materials are the basis of the synthetic fibre and plastics industries. PAHs are however, widespread pollutants and their impact on the environment and human health must be monitored and controlled. This book will review and assess our scientific understanding of the ecological exposure and effects PAHs have in different environments and habitats. It will accomplish this by taking the recipients of the pollution in the environment as starting points and working its way back through pathways to access what is required for our understanding of effects and rationale for control. Although this book will concentrate on ecological exposure of PAHs, the general impacts of PAHs on human populations will be touched upon. It is thought to be the first book to focus on the ecological aspects of PAHs.

Download or read book Earth Materials and Health written by National Research Council and published by National Academies Press. This book was released on 2007-05-09 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: A range of natural earth materials, like arsenic or fluoride, have long been linked to significant human health effects. Improved understanding of the pervasive and complex interactions between earth materials and human health will require creative collaborations between earth scientists and public health professionals. At the request of the National Science Foundation, U.S. Geological Survey, and National Aeronautics and Space Administration, this National Research Council book assesses the current state of knowledge at the interface between the earth sciences and public health disciplines. The book identifies high-priority areas for collaborative research, including understanding the transport and bioavailability of potentially hazardous earth materials, using risk-based scenarios to mitigate the public health effects of natural hazards under current and future climate regimes, and understanding the health risks that result from disturbance of earth systems. Geospatial information - geological maps for earth scientists and epidemiological data for public health professionals - is identified as one of the essential integrative tools that is fundamental to the activities of both communities. The book also calls for increased data sharing between agencies to promote interdisciplinary research without compromising privacy.
Download or read book Urban Stormwater written by Victorian Stormwater Committee, and published by CSIRO PUBLISHING. This book was released on 1999-10-28 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intense concentration of human activity in urban areas leads to changes in both the quantity and quality of runoff that eventually reaches our streams, lakes, wetlands, estuaries and coasts. The increasing use of impervious surfaces designed to provide smooth and direct pathways for stormwater run-off, has led to greater runoff volumes and flow velocities in urban waterways. Unmanaged, these changes in the quantity and quality of stormwater can result in considerable damage to the environment. Improved environmental performance is needed to ensure that the environmental values and beneficial uses of receiving waters are sustained or enhanced. Urban Stormwater - Best-Practice Environmental Management Guidelines resulted from a collaboration between State government agencies, local government and leading research institutions. The guidelines have been designed to meet the needs of people involved in the planning, design or management of urban land uses or stormwater drainage systems. They provide guidance in ten key areas: *Environmental performance objectives *Stormwater management planning *Land use planning *Water sensitive urban design *Construction site management *Business surveys *Education and awareness *Enforcement *Structural treatment measures *Flow management Engineers and planners within local government, along with consultants to the development industry, should find the guidelines especially useful. Government agencies should also find them helpful in assessing the performance of stormwater managers. While developed specifically for application in Victoria, Australia, the information will be of value to stormwater managers everywhere.

Download or read book Pyrethroid Insecticides written by Ethel Eljarrat and published by Springer Nature. This book was released on 2020-08-04 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the latest developments concerning the analysis, fate, behaviour and toxicity of pyrethroid insecticides. Over the last few decades, pyrethroid insecticides have increasingly replaced organochlorine pesticides due to their relatively lower mammalian toxicity, selective insecticide activity and lower environmental persistence. They represent 25% of global sales of insecticides, and are considered to be “safe” since they are converted to non-toxic metabolites by oxidative metabolism in fish and by hydrolysis in mammals. However, recent studies have demonstrated their environmental ubiquity, their bioaccumulation and their toxicity in various aquatic and terrestrial organisms, and even in humans. Featuring contributions by leading experts, the book discusses the physico-chemical properties and uses of pyrethroid insecticides; the latest chemical analytical methods; their occurrence in the environment, biota and food; and their isomeric and enantiomeric behaviour. It particularly highlights the toxicological effects and human exposure to pyrethroid insecticides, and also offers insights into the effects of the salmon industry on the marine environment with a case study of sea lice treatment using pyrethroids. This comprehensive book is a valuable source of information for environmental scientists, policymakers and producers interested in issues related to pyrethroid insecticides.
