This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The applications of fertilizers and pesticides to home lawns may contribute to the deterioration of ground and surface water quality. Loss of nutrients and pesticides to ground and surface water can be detrimental for human consumption, reduce recreational usage, and negatively impact aquatic organisms. A field study was initiated to examine the effect fertilizer and pesticide applications can have on the concentrations and mass loss of nutrients and pesticides in leachate and runoff. Studies were arranged on a slope of 13-15% of Arkport Sandy Loam soil (coarseloamy, mixed, active, mesic Lamellic Hapludalf) through establishing Kentucky bluegrass (Poa pratensis L.) sod, or mixtures of Kentucky bluegrass sod and traditional weedy species (Taraxacum officinale, Trifolium repens, Plantago major, and Digitaria ischaemum) found in the Northeast of the U.S. Runoff and leachate collected from natural precipitation events were analyzed for nitrate (NO3--N), ammonium (NH4+-N), total Kjeldahl nitrogen (TKN), phosphate (PO43--P), total Kjeldahl phosphorus (TKP), and applied pesticides. Nitrate contributions in leachate reflected the overall largest potential loss from the landscape. Differences were observed among lawn types for NO3--N loss; however significant losses were seen from lawn types regardless of the application of supplemental fertilizer. Ammonium and PO43--P losses in runoff were significantly higher for the fertilized turfgrass plots compared to non-fertilized lawn types. Although differences in nutrient losses occurred from lawn types, less than 2% of total applied N was lost in leachate and less than 1% and 0.5% of N and P applied were lost in runoff respectively. Pesticide applications could pose a risk to water quality, but the risk to off-site surface water contamination appears to be much more prevalent. Over-time, levels of pesticides in runoff were reduced; however during establishment, concentrations of 2,4-D and Mecoprop were greater than 2800 and 1600 [mu]g L-1, respectively, which could negatively impact aquatic organisms. Overall, differences in nutrient loading existed, but the ability of turfgrass to reduce runoff volumes and utilize applied nutrients appeared significant. The percent of nutrients contributed by fertilizer applications to ground and surface water was minimal and may not pose a significant environmental concern.

Download or read book Occurrence Fate and Transport of Pesticides and Their Degradation Products in Urban Environments written by Jaben Ross Richards and published by . 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 Diffuse Pollution written by N. Campbell and published by IWA Publishing. This book was released on 2005-02-01 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diffuse (non-point source) pollution is increasingly being recognised as a major source of water quality problems in both surface and ground water. Indeed, as pollution resulting from point sources is reduced by the efforts of regulators, diffuse sources frequently remain as the dominant source of pollution. The book is an introductory text covering the nature, causes and the significance of diffuse pollution of both urban and rural origin. Best management practices to tackle the problems are examined as are the ways in which the adoption of such practices may be brought about. Use is made of case studies from several countries to examine the strengths and weaknesses of various approaches. Diffuse Pollution covers both urban and rural sources. Urban sources include run-off from impermeable surfaces of roads, industrial areas and housing which may be contaminated by hydrocarbons, heavy metals, organic chemicals and other undesirable substances. Rural sources include water containing pollutants arising from agriculture and forestry such as plant nutrients, pesticides, microbes and soil itself. This concise book will prove useful to practitioners in the field of pollution control both in an urban and a rural environment, to regulators, to researchers new to the field, and to academics and students. An extensive reference section aids the reader in exploring the subject further.

Download or read book Urban Soils written by Rattan Lal and published by CRC Press. This book was released on 2017-10-18 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Globally, 30% of the world population lived in urban areas in 1950, 54% in 2016 and 66% projected by 2050. The most urbanized regions include North America, Latin America, and Europe. Urban encroachment depletes soil carbon and the aboveground biomass carbon pools, enhancing the flux of carbon from soil and vegetation into the atmosphere. Thus, urbanization has exacerbated ecological and environmental problems. Urban soils are composed of geological material that has been drastically disturbed by anthropogenic activities and compromised their role in the production of food, aesthetics of residential areas, and pollutant dynamics. Properties of urban soils are normally not favorable to plant growth—the soils are contaminated by heavy metals and are compacted and sealed. Therefore, the quality of urban soils must be restored to make use of this valuable resource for delivery of essential ecosystem services (e.g., food, water and air quality, carbon sequestration, temperature moderation, biodiversity). Part of the Advances in Soil Sciences Series, Urban Soils explains properties of urban soils; assesses the effects of urbanization on the cycling of carbon, nitrogen, and water and the impacts of management of urban soils, soil restoration, urban agriculture, and food security; evaluates ecosystem services provisioned by urban soils, and describes synthetic and artificial soils.

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.
