The Economic Impacts of Soil Contamination in Wenatchee, WA
This study determines the economic impacts of soil contamination as a result of historical pesticide use in Wenatchee, WA. A hedonic regression analysis of home values before, during, and after cleanups of six contaminated schoolyards demonstrates the public’s willingness to pay for remediated soil …

IMPACTS OF RDX SOIL CONTAMINATION ACROSS AN AGE GRADIENT FOR THE NATIVE SHRUB MORELLA CERIFERA.
Understanding the impacts of explosive contamination on vegetation is key to understanding explosives behavior in the environment. I quantified shrub growth responses to 1,3,5-trinitroperhydro-1,35-triazine (RDX) soil contamination across three life stages and I hypothesized that RDX would have the …

Legacy soil contamination by crude oil from the First Gulf War : geochemical characteristics, spatial pattern and environmental risk
… oil spills in Kuwait. Selection of appropriate soil remediation methods needs to be informed by accurate soil characterization and this knowledge is currently lacking. The aim of this PhD study was to obtain insights into the geochemical characteristics of the aged contaminated soils and, using …

Influence of diesel spillage on the productivity of ipomoea batatas and lactuca sativa
The effects of diesel contamination in soil on the germination, growth and dry matter partitioning in Lactuca sativa (crisp head variety) and Ipomoea batatas (dagga variety) were studied at two diesel concentration ranges 0-30 and 0-6 ml/kg soil. The first experiment tested the effects of diesel …

A comparison of soil management systems for urban agriculture
Soil contamination is a universal concern of urban agriculture. Reliable soil management systems are desirable in order to provide ideal growing conditions for urban crops. Due to concerns such as soil contamination, alternative soil management systems (e.g. raised-beds) are necessary to provide …

Remote sensing of grassland with contaminated soil using the spectral red-edge
In most cases contaminants are concealed in soil and under vegetation and therefore can<br/>not be measured directly by remote sensing. However, soil contaminants were detected<br/>using the spectral red-edge to indicate vegetation stress caused by the presence of<br/>the contaminants. An improved …

Quantification of neonicotinoid residues in soils and dust drift in conservation reserve program fields in Illinois, USA
… legacy neonicotinoid residues may persist in the soil of CP-42 habitats. In the study, soil and dust samples were collected from multiple CP-42 habitats located in east-central Illinois to survey for the presence of neonicotinoid residues. The field surveys were conducted in the spring planting …

Aplication of circular economy to manufacture sneakers from the banana pseudostem yarn
Traditional sneaker production uses water and soil contamination, due to the use of synthetic fibers and bad waste management. But new solutions have been developed, one of them being the replacement of natural fiber for synthetic fiber, one of the natural fibers is the banana fiber obtained from …

Disentangling Perceived and Measured Soil Health in New York City Urban Farms
Soil contamination is often addressed by constructing new compost-based soils for urban agriculture. We examined these constructed soils to assess soil health across a diversity of farming sites across New York City, consulting with farmers to characterize their soils as “healthy” or “unhealthy” …

Factors Influencing Salmonella Survival in Agricultural Soils and Internalization through Solanaceous Crop Roots
… occurred in the United States. The source of contamination for some of these outbreaks was traced back to the preharvest environment. Sources of contamination at the preharvest level of production often include irrigation water, soil, and the use of biological soil amendments of animal origin …

Hormone analyses of Black-Footed Albatross (Phoebastria Nigripes) at Midway Atoll NWR and Tern Island, Hawaiian Islands NWR
… has looked at the transfer of contaminants via soil to P. nigripes. However, studies have been done on how the Laysan albatross (P. immutabilis) is affected by lead in the soil (Work and Smith, 1996; Finkelstein et aI., 2003). Studies on endocrine disruption and effects of PCB contamination in …

Pore-scale processes : quantification of the controls on the transport of Ra and Cr, and development of a novel geochemical visualization tool
Addressing soil contamination inorganic metals and metalloids remains a critical task for the continuing protection of human health globally. The dissolved concentrations of contaminants are controlled by a wide range of biogeochemical processes including oxidation and reduction by microbes, …

Essays in applied microeconomics
… hazards and risk of water, atmosphere, and soil contamination. This paper quantifies these costs by estimating the effect of unplugged wells on housing prices. I use rich data on oil and gas drilling, housing market transactions, and lease agreements to conduct difference-in-differences and …

Environmental impact of heavy metal pollution in natural aquatic systems
The distribution of heavy metals between soil and soil solutions is a key issue in evaluating the environmental impact of long term applications of heavy metals to land. Contamination of soils by heavy metals has been reported by many workers. Metal adsorption is affected by many factors, including …

Μελέτη της κινητικής ανάπτυξης μικροοργανισμών κατά την βιοαποδόμηση τοξικών ρύπων σε πορώδη μέσα
Το πρόβλημα της ρύπανσης του εδάφους και του υδροφόρου ορίζοντα έχει πάρει ανησυχητικές διαστάσεις τις τελευταίες δεκαετίες. Η βιομηχανική ανάπτυξη πέρα απο τις θετικές συνέπειες που έχει για την ζωή των ανθρώπων, έχει δυστυχώς επιφέρει προβλήματα ρύπανσης του υπεδάφους και του υδροφόρου ορίζοντα …

Environmental and efficacy studies of a chromated fluoride wood preservative
… below toxic levels. Chemical analysis of field soils adjacent to creosoted remedially treated pole sections and 'on-line' poles confirmed that falls in timber fluoride concentrations were due to leaching to the surrounding soil. Leaching of chromium to soil was also established, probably …
