Question 8

NORM

Answer 8

Naturally Occurring Active Material

Question 9

Air Pollution

Answer 9

The presence in the outdoor atmosphere of one or more contaminents in such quantities and/or of such duration which may be injurious to human, animal , or plant health, or property, or which reasonably interferes with the comfort and enjoyment of life or property

Question 10

Clean Air

Answer 10

Air that is essentially odorless, tasteless, looks clear and has no measurable short or long term effects on humans animals or the environment.

Question 11

Areas of Air Sampling

Answer 11

1.Stack Testing
2. Indoor Air Quality/Industrial Hygiene
3, Ambient (Active and Passive)
4. Fugitive emmisions

Question 12

3 Types of Air Pollution

Answer 12

1. Micro
   - Local Level
   - Indoor air pollution resulting products used in construction, poor ventilation and exposure to NORM’s. (Naturally Occurring Active Material)
2. Meso
   - Industrial and mobile source contaminate the air that surrounds us.
3. Macro
   - Transport of ambient air pollution over large distances.

Question 13

Sources of Air Pollution

Answer 13

1. Natural
   - Volcanoes, cows, forest fires, swamp gasses, agriculture, etc.
2. Man Made
   - Cars, Industry, Smoking, Agriculture, etc.

Question 14

Common Air Pollutants

Answer 14

*CO2
*SO2
*Methane
*PM (Particulate Matter)
*H2S/TRS (Total reduced Sulphur)
*VOC’s (Volatile Organic Compound)
Ozone

Question 15

SOx

Answer 15

Sulphur Smell, Strong Odor.
Colorless
Possibility of Contracting Sulphur poisoning up to 72 hours after exposure.
Common Sources- sour gas plants and coal fired power plants.
Oxydizes to form SO3 which form H2SO4 in the presence of H2
Results in Acind Rains

Question 16

VOC’S

Answer 16

Volatile Organic Compound
VOC’s often written CH4 in testing
- also called THC’s (Total Hydrocarbons)
Consist of Organic Compounds with high vapor pressure
General term for solvents, fuels, & petroleum distillates

Question 17

CH4

Answer 17

Methane
Displaces O2
Can be explosive under certain concentrations levels
The principle component of Natural Gas

Question 18

CO

Answer 18

Colorless, Odorless, Poisonous
Incomplete combustion
Transportation accounts for 65% of CO production
CO enters blood stream and reduces O2 delivery to organs

Question 19

NOx

Answer 19

NO, NO2, N20
Often just referred to as NO2 in sampling
Pungent irritating odor
Transforms in air to form nitric acid
NO2 plays a roll in atmospheric rxns to create ground level ozone
precursers to nitrates forming respirable particulates
All combustion produces NOx at varried levels
NO2 is a lung irritant

Question 20

TRS

Answer 20

Total Reduced Sulphur
Offensive odor, rotten eggs
Only a health concern at high concentration
H2S causes immediate death
Includes compounds such as H2S, DMS, DMDS, & mercaptains

Question 21

Ozone

Answer 21

Major component of somg
Rxn btwn NO2 and VOC’s from ground level Ozone
Exposure results in chest tightness and coughing
Results in agricultural crop loss every year

Question 22

Types of Source Emmissions

Answer 22

Point - emissions forming from a single location
-eg. Stacks Flares Vents
Line- emissions running along a line in geography
-eg. Vehicles on a Highway
Area - emissions caused by a larger source, something that spans a distance
-eg. waste water ponds, fields
Volume - a larger 3 dimensional source of emissions
-eg. coal pile

Question 23

Purpose of Conducting Stack Survey

Answer 23

Compliance with AESRD (Alberta Stack Action Code)
Relative accuracy test audits (CEMS code)
Large Scale Projects
Equipment Design
Pollution Control Device Efficiency
Process Evaluation
NPRI (National Pollution Release Inventory)
GHG Reporting (Green House Gasses)
