An integrated assessment of air pollutant abatement opportunities in a computable general equilibrium framework
… and anthropogenic greenhouse gas emission reduction policies are desirable to reduce smog, tropospheric concentrations of ozone precursors, acid rain, and other adverse effects on human health, the environment, and the economy. While reduction of both air pollution and greenhouse gas …

Development of a Method to Compare Storm Water Best Management Practices at The University of Toledo
… BMPs are ranked based on flow quantity reduction, pollutant reduction, and payback period. The payback period includes capital costs associated with constructing the BMP as well as monetary values associated with environmental gains from implementing the BMP. This model provides the …

Performance Analysis of the Ashby Stormwater Retention Pond in Fairfax City, Virginia
… Virginia and local municipalities assign pollutant reduction credits to retention ponds that meet certain design requirements. However, to actually meet existing and future water quality goals set by TMDLs, it must be proven that such ponds truly provide the water quality benefits for …

Reduction of pollution levels in the Chatty River through Sustainable Drainage Systems: A case study of the Bethelsdorp River sub-catchment
… level in the Swartkops estuary has led to the reduction and even halting of various social and cultural activities such as the Redhouse River Mile swimming event, cleansing ceremonies by traditional healers, and baptisms by the Zion Church. SuDS are appropriate for a range of contexts and …

Thermochemical properties, bond energies and internal rotor potentials in methyl ethyl sulfide and oxygenated sulfur hydrocarbons intermediates for modeling its combustion and atmospheric chemistry
… for improvement of combustion processes and pollutant reduction. This study determines the structures, internal rotor potentials, bond energies and thermochemical properties ([Delta]fH , S and Cp(T)) of methyl ethyl sulfide (CH_3SCH_2CH3), a widely used sulfuric hydrocarbon, and its main …

Regulatory and Economic Consequences of Empirical Uncertainty for Urban Stormwater Management
… through the Clean Water Act's National Pollutant Discharge Elimination Systems' Stormwater (NPDES SW), and Total Maximum Daily Load (TMDL) programs. These programs require that regulated entities reduce the discharge of pollutants from their storm drain systems to the "maximum extent …

Analysis of best management practices implementation on water quality using the Soil and Water Assessment Tool (SWAT)
… Unfortunately, high discharge levels of these pollutants have led to major problems, affecting both health and the ecological balance. Discharged nutrients entering the Gulf of Mexico from the Mississippi River accelerate the growth of algae. When the algae die, the decomposing microorganisms …

Modeling phosphorus transport in surface runoff from agricultural watersheds for nonpoint source pollution assessment
… of phosphorus in the Chesapeake Bay. These pollutants, whether from point or nonpoint sources, have been found to be the primary cause of declining water quality in the Bay. Numerous studies have indicated that, for many watersheds, a few critical areas are responsible for a disproportionate …

Farm waste management: the effects of fine bubble aeration on cattle slurry and the fate of ammonia during the treatment process
… NH3 can present a significant atmospheric pollutant. Here aeration treatment was studied at laboratory-scale (1 litre) and pilot-scale (100 litres). Air was externally supplied to tubular fine bubble diffusers. Initially a settleable floculative microbial culture was developed using …

Co-Pyrolysis and Co-Combustion of Coal and Biomass
… for heat and/or energy production results in pollutant reduction. Most notable is the impact on the emission of NOx, SOx, volatile organic compounds and polyaromatic hydrocarbons. These latter compounds largely arise from their formation and release during incomplete combustion/gasification. …
