Policy Bridge: Air Quality Impacts from Oil and Natural Gas Development in Colorado
Published: 2019-12-13
Subjects: Environmental Education, Environmental Health and Protection, Environmental Monitoring, Environmental Sciences, Oil, Gas, and Energy, Physical Sciences and Mathematics
The rise of hydraulic fracturing techniques has fostered rapid growth of oil and natural gas extraction in areas across the United States. In the Denver-Julesburg Basin (DJB), which mostly overlaps with Weld County in the Northern Colorado Front Range (NCFR) north of the City of Denver Metropolitan Area (DMA), the well drilling has increasingly approached, and in many instances moved into urban [...]

Published: 2019-06-27
Subjects: Civil and Environmental Engineering, Civil Engineering, Computational Engineering, Earth Sciences, Engineering, Environmental Engineering, Environmental Health and Protection, Environmental Sciences, Geomorphology, Hydraulic Engineering, Hydrology, Life Sciences, Natural Resources and Conservation, Natural Resources Management and Policy, Operations Research, Systems Engineering and Industrial Engineering, Other Civil and Environmental Engineering, Other Engineering, Other Environmental Sciences, Other Physical Sciences and Mathematics, Physical Sciences and Mathematics, Probability, Risk Analysis, Statistics and Probability, Sustainability, Systems Engineering, Water Resource Management
The increasing impact of flooding urges more effective flood management strategies to guarantee sustainable ecosystem development. Recent catastrophes underline the importance of avoiding local flood management, but characterizing large scale basin wide approaches for systemic flood risk management. Here we introduce an information-theoretic Portfolio Decision Model (iPDM) for the optimization of [...]

The following work is a part of wider uranium prospecting programme of the Atomic Mineral Directorate for Exploration and Research (AMD) for mapping radioactive anomalies in mineralized regions of Siwalik, Himachal Pradesh. This study reports the analysis of average activity concentration, potential radiological hazards; radium equivalent activity (Raeq), external hazard index (Hex), internal [...]
Dispersion, accumulation and the ultimate fate of microplastics in deep-marine environments: A review and future directions
Published: 2019-04-03
Subjects: Earth Sciences, Environmental Health and Protection, Environmental Indicators and Impact Assessment, Environmental Monitoring, Environmental Sciences, Natural Resources and Conservation, Physical Sciences and Mathematics, Sustainability
An estimated 8.3 billion tonnes of non-biodegradable plastic has been produced over the last 65 years. Much of this is not recycled and is disposed into the sedimentary system, has a long environmental residence time and accumulates in sedimentary systems worldwide, posing a threat to important ecosystems and potentially human health. We synthesise existing knowledge of seafloor microplastic [...]
Mapping geospatial processes affecting the environmental fate of agricultural pesticides in Africa
Published: 2019-04-02
Subjects: Environmental Health and Protection, Environmental Sciences, Physical Sciences and Mathematics
The application of agricultural pesticides in Africa has high negative effects on human health and the environment. To analyse the effect, spatial data characterizing the environmental fate of agricultural pesticides are needed. However, poor availability and quality of data that quantify pesticide application and pesticide fate limit direct analysis of the effect. This study selected key [...]

Among all Arctic seas, the Barents Sea is characterized by its unique environment and high level of the biodiversity. At the same time the Gulf Stream waters transport large amounts of pollutants in the Barents Sea bringing various contaminants and substances from the North Sea. Nowadays, there are in Timan Pechora-Carboniferous basin located in the Barents Sea with 76 oil and gas subsidies, [...]
