  1. Criteria Air Pollutants

  2. PM 10 PM 2.5 • *Power plant boilers • steel mills • *Chemical plants • *Unpaved roads & parking lots • Wood-burning stoves & fireplaces • Automobiles & other. Aggravates respiratory effects like asthma & emphysema. May cause lung and heart problems. May carry toxic material deep into the respiratory system. Impairs visibility • Pollution control equipment (wet & dry scrubbers & cartridges) • Electrostatic precipitators.

  3. Power plant burning coal, pwrplt boilers, sulfuric acid plants, petroleum refineries, smelters, paper mills, & fuel combustion in diesel engines. • Respiratory irritant. • Aggravates lung & heart problems. • + water = sulfuric acid. • Sulfuric acid can damage marble, iron, steel & damage crops & vegetation, leach Al from soil. • Crushing limestone & mixing it with coal. Dry or wet • Low sulfur coal.

  4. Incomplete combustion of carbon-based fuels in motor vehicle & industrial boilers. Reduces the ability of blood to deliver oxygen affecting the cardiovascular & nervous system. Impairs vision, causes dizziness, & can lead to unconsciousness or death. Transportation planning, vehicle emissions testing, pollution equipment.

  5. Emissions of volatile organic compounds (VOC) & nitrogen oxides in the presence of sunlight. Fuel combustion in motor vehicles, gasoline storage & transport, solvents, pains & landfills. Irritates mucous membranes, aggravates lung & heart problems. Damages rubber, some textiles & dyes. Damages plants. Reduces crop yields. • Use of low-VOC solvents. • evaporative controls • vehicle emissions testing • pollution control equipment.

  6. Fuel combustion in motor vehicles & industrial sources. High temperature burning combining nitrogen & oxygen in the air. • Respirator irritant. • Aggravates lung & heart problems. • Precursor to ozone & acid rain. Causes brown discoloration of atmosphere. • Staged burning; 1st high temp. w/ low oxygen which prevents most NOx from forming. • 2nd Afterburner uses rich oxygen mix. 50% reduction. • Exhaust gas recirculation in cars, reduction of combustion. • Catalytic converters reduce 90% of NOx.
