To understand the effects of diffuse pollution information on the source of pollutants, quantities in transport, mode of transport, transient nature of the pollution event, and most importantly, a consideration of remediation efforts need to be known.
The reports usually identify the pollutants, the quantity, the geographic spread and any cleanup efforts.
As typical chlorinated organic pollutants, large quantities of PCB byproducts are released into the environment causing serious pollution and adverse impacts on ecosystems [2, 3].
Then, a known quantity of pollutant (e.g. CO, propane) was injected into the exhaust, so as to create an approximated pulse input into the DOC (e.g. with peak CO concentration = 3000 ppm).
During diffusion phase, more quantity of pollutant is extracted at low flowrate than at high flowrate.
A lower system cost would be incurred if a larger quantity of pollutant emission is allowable; meanwhile, the planning scheme with a higher cost would urge the environmental quality maintain at a higher level.
However, rates of over 16% water exchange increase operating costs, such as the amount of fuel used, as well as increasing the quantity of pollutant inputs [ 8].
The reflection of such pollution in the karst underground waters depends on the type and quantity of pollutants, and on the rock structure through which the waters penetrate.
In an extensive analysis of geographic exposure modeling and its usefulness in environmental epidemiology (Beyea and Hatch 1999), the authors emphasized the importance of considering all uncertainty aspects when making the models: type and quantity of pollutants, their pathways into surroundings, exposed population, and time of pollution.
Long Beach and central Los Angeles are congested urban areas where air quality is dominated by fresh emissions from air pollution sources; Azuasa and Rubidoux are located farther downwind and receive transported air pollutants plus increased quantities of the products of atmospheric chemical reactions.
