Screening method for regulatory purposes in the Argentine Republic
This paper presents a comparison between the screening method in accordance with the requirements of the Argentine regulations and the detailed screening procedures recommended by the United States Environmental Protection Agency (US-EPA). Both methodologies are applied to different scenarios of point sources in rural and urban areas. The intercomparison between both screening estimations is ...
Quality control in dispersion modeling: Validation of a screening model for PM10 and NO2
European air quality guidelines require gathering information about air quality at locations where the population is affected or possibly affected by high concentrations. High concentrations are often found in densely built up streets with high traffic loads. In order to identify these hot spots and to assess possible measures to improve the situation, screening models are widely applied in ...
Pennsylvania's US Environmental Standards on Vapor Intrusion
Vapor intrusion occurs due to volatile substances found in groundwater or soil, and they find their way into buildings inhabited by human beings. Vapor phase intrusion of the volatile substances is a threat to human health. The Pennsylvania Department of Environmental Protection (PADEP) provides guidelines and standards used for the evaluation of vapor intrusion under site-specific standard (SSS) ...
Balancing simplicity with accuracy in the use of dispersion modelling in the United States
Dispersion modelling has been a requirement of air-quality regulatory agencies in the United States for over 20 years. Over the years, the task of performing this modelling has shifted from the regulatory agency to the applicant. One purpose of the modelling is to show that air-quality standards or air toxic guidelines will not be exceeded when the proposed modification or new facility is ...
