Combustion Sources of Residential Air Pollution: An Overview
Combustion by-products are a major source of indoor air pollution and have been measured in homes at levels above typical outdoor concentrations, and at levels which approach or exceed...
Development of Data Quality Indicators for Indoor Air Pollution Measurements
Indoor air quality measurements pose a unique problem for the application of traditional Quality Assurance/Quality Control approaches. The lack of reference methods and materials in some...
Special Water Treatment in New Jersey
The New Jersey Department of Environmental Protection (NJDEP) performed a study on 'special water treatment'. The main goal of the project was to assess in detail...
Integration of EPA Guidelines Air Quality Models with Human Exposure/Risk Estimation Procedures
Techniques, based on dispersion models which are currently available, for performing population and maximum individual exposure and risk assessments due to ambient air emissions are described....
Removal of Radon and Uranium from a water supply
The removal of Radon and Radium from drinking water with the help of granulated activated carbon (GAC) adsorption was investigated. A packed bed column was used for the purpose. It has...
Health Effects,Risk Assessment and Guidance for Indoor Radon
Unlike many inorganic elements, radionuclides have no nutritional value. Radionuclides are carcinogenic and uranium is also known to be non-carcinogenic as well. This paper is primarily...
Treatment Facilities and Costs for the Removal of Radon from Ground Water Supplies
Two methods for removal of Radon from drinking water are considered: activated carbon adsorption and packed tower aeration. Although both granular activated carbon (GAC) and packed tower...
Current Status of Flue GasDesulfurization in the United States
Flue gas desulfurization (FGD) systems have been in existence in the United States for only 17 years but they have made a tremendous impact in the operation of utility plants. At present,...
On the Ship's Waterways Passing Through Bridges
This paper reports on a study of bridge openings that serve as waterways, in view of the analysis of ship collision accidents. For the purpose of this study, cases of ship collision accidents...
