In Chemistry Transport Models (CTMs), spatial scale interactions are often represented through off-line coupling between large and small scale models. However, those nested configurations cannot give account of the impact of the local scale on its surroundings. This issue can be critical in areas...

A variety of global metrics indicate the Earth has overshot its capacity to supply source and sink resources without substantial negative feedback. Here the relationship between consumption indicators (oil, freshwater, vehicle and meat consumption, GDP, $mathrm{CO }_{2}$ CO 2 emissions) an...

Marsh sediment accumulation is predominately a combination of in situ organic accumulation and mineral sediment input during inundation. Within the Pamlico River Estuary (PRE), marsh inundation is dependent upon event (e.g., storms) and seasonal wind patterns due to minimal astronomical tides (...

Green supply chain management (GSCM) integrates ecological concepts with those of supply chain management in order to minimize energy and material usage and to reduce adverse impacts of supply chain activities on the environment. GSCM implementation in mining industries depends largely upon certa...

The effects of maneb were investigated in C57BL/6 Nrf2 wildtype and knockout mice. Treated KO mice showed significant weight loss as compared to WT counterparts. ICPAAS analysis demonstrated a significant increase in manganese concentration in the tissues of treated KO mice as compared to WT. Bio...

Life cycle assessment (LCA) of a microalgae biomass cultivation, bio-oil extraction and pyrolysis processing regime is a useful means to gauge the likely environmental impact of this prospective new development on an industrial scale. Coupled to thermal conversion via slow pyrolysis, the prospect...

A free water surface constructed wetland (CW) designed for effluent treatment was dominated by the emergent macrophyte Typha domingensis reaching a cover of roughly 80% for 5 years. Highly efficient metal and nutrient removal was reported during this period. In June 2009, a population of approxim...

The East-Ural Radioactive Trace (EURT) is a result of the Mayak Production Association accident that occurred in 1957 in Russia. Radiological assessment improves the interpretation of biological effects of exposure to ionizing radiation. Therefore a modeling approach was used to estimate dose rat...

It has been suggested that Xenopus laevis is less sensitive to some chemicals than other amphibians and therefore, the Frog Embryo Teratogenesis Assay-Xenopus (FETAX) may have limited use in risk assessments for other amphibians. However, comparisons are mostly based on results of FETAX which emp...

As the production and applications of nano silver (nano Ag) increase, it is essential to characterize fate and effects in environmental systems. Nano Ag materials may settle from suspension, therefore, our objective was to utilize environmentally relevant bioassays and study the impact, bioaccumu...

On December 22, 2008 a dike containing coal fly ash from the Tennessee Valley Authority Kingston Fossil Plant failed and resulted in the largest coal ash spill in U.S. history. This study was designed to determine sediment metal concentrations at multiple site locations and to determine if site-s...

Simulation of the increase of sorption in time is one of the options in higher tiers of pesticide regulatory leaching assessments to obtain more realistic leaching estimates. Therefore, accurate estimates of non-equilibrium sorption parameters are required as input for the pesticide leaching scen...
