  • Air pollution has been a major transboundary problem and a matter of global concern for decades. High concentrations of different air pollutants are particularly harmful to large cities residents, where numerous anthropogenic activities strongly influence the quality of air. Although there are many books on the subject, the one in front of you will hopefully fulfill some of the gaps in the area of air quality monitoring and modeling, and be of help to graduate students, professionals and researchers....

  • Environmental Engineer’s Mathematics Handbook brings together and integrates in a single text the more practical math operations of environmental engineering for air, water, wastewater, biosolids and stormwater. Taking an unusual approach to the overall concept of environmental engineering math concepts, this offers the reader an approach that emphasizes the relationship between the principles in natural processes and those employed in engineered processes.

  • Ecotoxicological models have been applied increasingly to perform chemical risk assessments since the first models of this kind emerged about 25 years ago. The first ecotoxicological models were applied to very specific cases — for instance, cadmium contamination of Lake Erie or mercury contamination of Mex Bay, Alexandria. The models were inspired by the experience gained in ecological modeling and therefore contained good descriptions of ecological processes. Slightly later, the so-called fate models emerged, which were first developed by McKay and others.

  • The use of models to provide additional details on contaminant fate and transport has rapidly increased in the past 3 decades. The increasing global recognition of the potential risks associated with surface water or ground water contamination and speciÞc environmental regulations implemented after 1980 have demanded a more accurate understanding of these risks as they relate to human health and the environment.

  • Analysis and abatement of air pollution involve a variety of technical disciplines. Formation of the most prevalent pollutants occurs during the combustion process, a tightly coupled system involving fluid flow, mass and energy transport, and chemical kinetics. Its complexity is exemplified by the fact that, in many respects, the simplest hydrocarbon combustion, the methane-oxygen flame, has been quantitatively modeled only within the last several years.

  • About 70% of the world’s population dwells in coastal zones. With the economic and population growth, the shortage in freshwater supply becomes increasingly acute. With surface water more and more depleted and polluted, coastal communities have turned to groundwater to make up for the shortfall. For domestic supply purposes, the percentage of groundwater use has increased to more than 40% on a worldwide basis.

  • Weather natural hazards, the environment and climate change are of concern to all of us. Especially, it is essential to understand how human activities might impact the nature. Hence, monitoring, research, and forecasting is of the outmost importance. Furthermore, climate change and pollution of the environment do not obey national borders; so, international collaboration on these issues is indeed extremely important.

  • In the Asian monsoon and adjacent regions, the aerosol forcing and responses of the water cycle are even more complex. Both direct and indirect effects may take place locally and simultaneously, interacting with each other. In addition to local effects, monsoon rainfall may be affected by aerosols transported from other regions and intensif ied through large-scale circulation and moisture feedbacks.

  • We use three models to estimate health damages from PM10. First, we use an air dispersion model to estimate each source’s contribution to annual average ambient levels of PM10 at several thousand receptor locations in Paso del Norte. Next, we use a health effects model to estimate the number of cases of human mortality and morbidity that result from this pollution each year. Finally, we use a valuation model to calculate the dollar values of these health impacts. This section briefly discusses each of these models. A more detailed discussion is available in Blackman et...

  • Unlike stratospheric ozone that protects life on earth, tropospheric ozone is highly toxic and is the main pollutant of the atmosphere of industrialized countries and cities. Its precursors are emanated from industrial activities and traffic. Generated by lightning, photochemical reactions or with free radicals, it has a density of 1.66 times greater than air and is maintained close to the ground. It decomposes easily, generating free radicals with oxidizing power. The main primary pollutants leading to ozone formation are nitrogen oxides, volatile organic compounds and methane.

  • Our estimated results are therefore consistent and free frombias. Fourth,we investigate the impact of amore comprehensive set of demographic factors on pollution including the age composition, the urbanization rate and the average household size.Many existing econometric studies neglect demographic factors other than total population size. Parikh and Shukla’s (1995) analysis of the effect of the urbanization rate on energy use and greenhouse gas emissions in developing countries represents a notable exception in this regard....

  • Mangalore coast is a stretch of about 22 Kms at the western part of the Western Ghats of the Indian peninsula. This area is receiving huge quantity of pollution load from the major industries and factories located nearby. This pollution load is discharged into the sea either directly or through the major west flowing rivers of the region, Nethravathi and Gurupura. The pollution load includes runoff of the sediment, waste from oil refineries, nutrients and pesticides, iron ore residues from the nearby iron are company and chemicals from the chemical factory from the point source.
