This book was released on 2007 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greater than 50% of all class B biosolids produced in the US are reused by application to agricultural land. The goal of this research was to pair a comprehensive literature review with a field aerosol sampling campaign to characterize aerosols emitted during the land application process and provide a simplified framework for evaluating exposure to on-site workers and off-site residents. Three aerosolization scenarios for dewatered biosolids were considered and include spreading biosolids onto land by side slinging, disk incorporating into soils, and aerosolization of land applied biosolids due to high wind events. Particulate mater, metal aerosols, and biological aerosols of biosolids origin were in the respirable size range and were markedly greater downwind of land application than in upwind ambient control sites. Low level aerosolization of field applied biosolids were detected during high wind events, and biosolids derived aerosols were detected at 170 meters downwind of disk incorporation.The ability to reconstruct source aerosol concentration from PM10 measurements and the linear correlations made between bulk biosolids concentrations and source emission rates serve as a framework for determining relevant aerosol concentrations without the requirement of biological or chemical aerosol sampling. Application of this framework eliminates the inherent limitations and costs associated with monitoring low aerosol concentration of toxic compounds and pathogens.

This book was released on 2011 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Land-application of biosolids is an important means of disposal with possible benefits for soil quality. Bioaerosols might be generated from the application of biosolids and the possible human health risk of pathogenic microorganisms contained in bioaerosols has become an increasingly important issue. Microbial evidence thus far has suggested human health risks are minimal during application of biosolids; however epidemiological studies have reported increased numbers of infection in residents living near biosolids application. Previous studies have focused on the quantification of aerosolized bacteria and the presence of indicator species, while the currenty study uses a DNA-based method to detect alterations to the genetic composition of the aerosolized community following biosolids application. The current study collected soil and aerosol samples from a field site receiving land-applied Class B biosolids. Samples were collected prior to application and over the course of a ten week period following application. Analysis of the data suggested densities of bacteria in aerosol samples did not increase following the application of biosolids. A DNA-based community approach was utilized to investigate the composition of the communities. No change in the community composition was observed after the application of biosolids. Biosolids did not significantly contribute to the airborne population of bacteria in the current study.
Download or read book Biosolids Applied to Land written by National Research Council and published by National Academies Press. This book was released on 2002-10-01 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1993 regulation (Part 503 Rule) governing the land application of biosolids was established to protect public health and the environment from reasonably anticipated adverse effects. Included in the regulation are chemical pollutant limits, operational standards designed to reduce pathogens and the attraction of disease vectors, and management practices. This report from the Board on Environmental Studies and Toxicology evaluates the technical methods and approaches used by EPA to establish those standards and practices, focusing specifically on human health protection. The report examines improvements in risk-assessment practices and advances in the scientific database since promulgation of the regulation, and makes recommendations for addressing public health concerns, uncertainties, and data gaps about the technical basis of the biosolids standards.

This book was released on 2003-05-03 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioavailability refers to the extent to which humans and ecological receptors are exposed to contaminants in soil or sediment. The concept of bioavailability has recently piqued the interest of the hazardous waste industry as an important consideration in deciding how much waste to clean up. The rationale is that if contaminants in soil and sediment are not bioavailable, then more contaminant mass can be left in place without creating additional risk. A new NRC report notes that the potential for the consideration of bioavailability to influence decision-making is greatest where certain chemical, environmental, and regulatory factors align. The current use of bioavailability in risk assessment and hazardous waste cleanup regulations is demystified, and acceptable tools and models for bioavailability assessment are discussed and ranked according to seven criteria. Finally, the intimate link between bioavailability and bioremediation is explored. The report concludes with suggestions for moving bioavailability forward in the regulatory arena for both soil and sediment cleanup.

This book was released on 2018-04-30 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document presents key messages and the state-of-the-art of soil pollution, its implications on food safety and human health. It aims to set the basis for further discussion during the forthcoming Global Symposium on Soil Pollution (GSOP18), to be held at FAO HQ from May 2nd to 4th 2018. The publication has been reviewed by the Intergovernmental Technical Panel on Soil (ITPS) and contributing authors. It addresses scientific evidences on soil pollution and highlights the need to assess the extent of soil pollution globally in order to achieve food safety and sustainable development. 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers the topic of microplastics in water and wastewater. The chapters start with introductory issues related to the growing interest in the scientific community on microplastics and the human water cycle and point out where the microplastics could interact with water. The subsequent chapters examine evidence of the microplastic presence in freshwater, such as in both rivers and lakes, in freshwater biota, and hazardous chemicals associated with microplastics in such systems. Another set of chapters discuss the presence of microplastics in wastewater: their sources; their transfer through a wastewater treatment plant; the concentration of microplastics in effluents throughout the world; the plastic biomedia used in wastewater treatment plants and the effect on the surrounding environment of effluent wastewater pipes. These chapters also discuss the sampling methods, the sample treatment and analysis techniques used so far for microplastics in wastewater. Additionally, the presence of microplastics in sewage sludge and in soils irrigated with wastewater or fertilized with sludge are discussed. The possible impact of plastics and their additives on plants, microalgae, and humans are reviewed and presented in a critical way. Finally, a chapter summarizes all the relevant regulations and initiatives that point to the necessity of a global directive for the protection of the environment from plastic and microplastic pollution. The topic of microplastics in freshwater systems and in wastewater has scarcely been studied and requires more attention. Microplastics in Water and Wastewater aims to bring these initial findings to the attention of a broader audience and especially to operators and managers of freshwater and wastewater systems. It will also be helpful to people already aware of the marine debris problem to understand the sources of microplastics in the oceans, from freshwater systems and wastewater treatment plants.

This book was released on 2003-04-07 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air Emissions from Animal Feeding Operations: Current Knowledge, Future Needs discusses the need for the U.S. Environmental Protection Agency to implement a new method for estimating the amount of ammonia, nitrous oxide, methane, and other pollutants emitted from livestock and poultry farms, and for determining how these emissions are dispersed in the atmosphere. The committee calls for the EPA and the U.S. Department of Agriculture to establish a joint council to coordinate and oversee short - and long-term research to estimate emissions from animal feeding operations accurately and to develop mitigation strategies. Their recommendation was for the joint council to focus its efforts first on those pollutants that pose the greatest risk to the environment and public health.
