Types of indoor air pollutants - CO, Radon, Asbestos, Lead, Nitrogen Oxides, VOC
(offgassing) dust particles, Mold, Bacteria
Radon, What is it? - Decay of radioactive elements in the earth. Enters through cracks
in holes and service pipe penetrations. It can diffuse through concrete and brick and
wood. Colorless, Odorless, Tasteless.
Radon Limit in Water - 4 pci/L of air. One billionth of a curi
Asbestos - Long thin fibrous mineral. Released into the atmosphere if disturbed.
(Friable) held in suspension in the air.
Most common places to find lead. When was it banned? - Paint, plumbing, flashing.
Banned in 1978
What does mold require to live - Moisture, food source, right temp
Most common places to find mold - Places with high delta T and moist places
Carbon Monoxide, how is it formed? - Incomplete combustion. Colorless, odorless,
tasteless
CO thresholds in air - Below 9ppm 24 hrs. Good. 35 PPM disable appliances., identify
source. 35 ppm for 1 hr.
Clues for Carbon Monoxide - Carbon buildup, dirty burners, lazy flames, fails CO test.
What is correlated color temperature - Color appearance measured in degrees kelvin.
Bulbs are stamped, <3200K warm, 3200-4000 Neutral. >4000 Blue White
Color Rendering Index (CRI) - measurement showing effect of a light source on the
color of objects based on a 0 to 100 scale. Not all light sources propduce the right color
compared to naturally
Luminous efficiency - How many lumens you get vs watts
incandescent - Low efficiency, most energy goes to heat, light produced by glowing
tungsten wire
fluorescent - Requires ballast control, has mercury gas in it
