Study Notes
Air Pollution: Air Quality & Monitoring
- Air quality is a dynamic and complex environmental phenomenon with large temporal and spatial variations.
- Variations in air quality are caused by changes in pollutant source emission rates and changes in meteorology and topography.
- These changes influence chemical reactions and control/removal of atmospheric pollutants.
Clean Air Act (CAA)
- The EPA defines ambient air as the portion of the atmosphere outside buildings accessible to the public.
- The CAA regulates pollution entering the outside air, including emissions from sources like stacks, chimneys, vents, etc.
- These emissions can be point source (e.g., specific factory) or area source (e.g., citywide) depending on size.
- Mobile and fugitive emissions directly released into the atmosphere are also regulated.
- The CAA does not regulate indoor air pollution or air pollution confined to private property.
National Ambient Air Quality Standards (NAAQS)
- The EPA establishes NAAQS standards for pollutants.
- Six criteria air pollutants are regulated: ozone, particulates (PM10 and PM2.5), sulfur oxides, carbon monoxide, nitrogen dioxide, and lead.
- Ozone is not directly emitted but formed from volatile organic compounds (VOCs) and nitrogen oxides (NOx) in sunlight.
- Standards depend on the time period over which measurements are averaged.
Types of NAAQS
- Primary standards protect human health and environment. They are "health-based" and protect sensitive segments of the population (children, elderly, asthma sufferers).
- Secondary standards protect public welfare and prevent damage to property (animals, plant life).
- Both primary and secondary standards specify maximum pollutant concentrations allowed in ambient air.
NAAQS (Primary & Secondary) - Specific Pollutants
- Pollutant data provided includes specific standards (e.g., average concentrations, maximum levels) for different time periods (e.g., hourly, annually, 24 hours) for various pollutants (e.g., CO, Pb, NO2, O3, PM10/PM2.5, SO2).
- There is noted correlation between standards and whether they reflect primary or secondary standards.
Air Monitoring
- Air quality monitoring is complex requiring detailed data related to spatial and temporal variations.
- Ambient air quality monitoring systemically assesses pollutant levels in communities.
- Monitoring is crucial in urban areas, near large pollution sources, and at sensitive environmental receptors.
- Data collection and analysis are essential for understanding air quality, predicting future pollution levels, and effective dispersion model development.
Portable Monitoring
- Mobile monitoring uses platforms like aircraft or vehicles for data collection.
- It enables understanding of atmospheric transport, chemical transformations, photochemical smog, acidic deposition, and pollutant dispersion.
- Mobile monitoring can be used to find areas with high pollutant concentrations (hotspots).
- It's also useful for monitoring sites impacted by spills or accidents.
Air Quality in Jordan
- Jordan's air quality is particularly challenging in areas with high vehicular traffic and industry density.
- Major sources of pollution include vehicles, industries, and residential activities.
- Data detail emission sources (e.g., road transport, diesel, industrial energy) and their contributions to air pollutants (e.g., TSP, PM10, NOx).
- Vehicle fleets are dated, which significantly contributes to pollution.
- Specific industrial sources (e.g., cement plants, power plants) are key pollution contributors, often impacting significant environmental receptors (e.g., mining activities).
Stationary Monitoring
- A stationary monitoring network provides background concentration levels, highest concentration levels in high-density areas, the impact of local/remote sources, and the relative influence of natural/anthropogenic sources.
- Spatial scales of monitoring range from microscopic to regional levels (e.g., 1-100 meters; 100m-half-km; half-km to 4 km; etc).
Relationship of Representativeness and Monitoring Objectives
- Correlations are noted between siting scales (e.g., micro, middle, neighborhood, region) and monitoring objectives (e.g., highest concentration effect, source impact).
Main Sources of Emissions & Monitoring Institutions
- Tables provide data on the sources of pollutants (e.g., cement plants, industrial plants, traffic) and monitoring institutions responsible for observation (e.g., ministries, research facilities).
- Frequency and general types of pollutants monitored are noted.
