This project is aimed at studying environmental pollution using ion-beam analysis (IBA) techniques. The work will focus initially on the analysis of aerosol samples collected around New York State and will eventually be extended to include soil, water, sh, and tree samples. The samples will be analyzed using the IBA techniques of particle-induced X-ray emission, proton elastic scattering, parti...

some contaminants associate with soil particles and, thus, their transport and fate in the environment is determined by the soil erosion processes. eutrophication, low oxygen levels and high nutrient (nitrogen and phosphorus) concentrations in reservoirs, canals and other water courses, is a common water pollution feature. phosphorus (p) is one of the major plant nutrients and also the major nu...

[1] Summer soil moisture increased significantly from 1958 to the mid 1990s in Ukraine and Russia. This trend cannot be explained by changes in precipitation and temperature alone. To investigate the possible contribution from solar dimming and upward CO2 trends, we conducted experiments with a sophisticated land surface model. We demonstrate, by imposing a downward trend in incoming shortwave ...

To enhance the quantitative simulation and integrated assessment of non-point source (NPS) pollution in plateau lakes in data-poor regions, a simple and practical NPS assessment method is developed by combining the improved export coefficient model (ECM) and the revised universal soil loss equation (RUSLE). This method is evaluated via application to the Chenghai Lake watershed (Yunnan Province...

Arsenic pollution became a great problem in the recent past in different countries including Bangladesh. The microlevel studies were conducted to see the spatial variation of arsenic in soils and plant parts contaminated through ground water irrigation. The study was performed in shallow tube well command areas in Sadar Upazila (subdistrict), Faridpur, Bangladesh, where both soil and irrigation...

Although environmental pollution was first realized to be a threat to public health in the latter part of the 20th century, events in the 21st century have served to increase the public awareness of the impacts of environmental pollution. Several communities, including the scientific community initiated dialogues to help protect the planet from environmental pollution. Further, scientific commu...

Soil erosion associated with non-point source pollution is viewed as a process of land degradation in many terrestrial environments. Careful monitoring and assessment of land use variations with different temporal and spatial scales would reveal a fluctuating interface, punctuated by changes in rainfall and runoff, movement of people, perturbation from environmental disasters, and shifts in agr...

Salt pollution and human-accelerated weathering are shifting the chemical composition of major ions in fresh water and increasing salinization and alkalinization across North America. We propose a concept, the freshwater salinization syndrome, which links salinization and alkalinization processes. This syndrome manifests as concurrent trends in specific conductance, pH, alkalinity, and base cat...

Environmental protection of urban areas requires a wide range of data about air pollution, water pollution, soil pollution, waste management, noise, transport, landscape, and energy supply. In order to perform impact assessment and model predictions, various techniques of short-term, medium-term and longterm monitoring are required for spatial processing and time series analysis. The Geographic...
