18 Questions
What are some examples of toxic metals often found as air pollutants?
Lead and mercury
What are Persistent Organic Pollutants (POPs) and why are they a concern?
Organic compounds resistant to environmental degradation; capable of long-range transport, bioaccumulate, and have significant impacts on health and environment
How are Persistent Organic Pollutants (POPs) different from other pollutants?
They are resistant to environmental degradation through various processes
What does CFCs stand for, and why are they harmful to the ozone layer?
Chlorofluorocarbons; harmful to the ozone layer emitted from products currently banned from use
What kind of health impacts can be associated with airborne fine particles linked to persistent free radicals?
Cardiopulmonary disease (Heart disease)
Give an example of an odor-related primary air pollutant.
Odors from garbage, sewage, and industrial processes
What are primary pollutants and provide an example?
Primary pollutants are directly produced from a process, such as ash from a volcanic eruption.
Explain how secondary pollutants are formed and provide an example.
Secondary pollutants are formed in the air when primary pollutants react or interact, such as the formation of ground level ozone from these interactions.
What is the major primary pollutant related to sulfur compounds?
Sulfur oxides (SOx), especially sulfur dioxide (SO2).
How is nitrogen dioxide (NO2) primarily generated?
Nitrogen oxides (NOx), especially nitrogen dioxide, are expelled from high temperature combustion.
What is a major source of carbon monoxide (CO) emissions?
Vehicular exhaust is a major source of carbon monoxide.
Explain the significance of volatile organic compounds (VOCs) as outdoor air pollutants.
VOCs are an important outdoor air pollutant.
What skin diseases have been linked to air pollution?
Eczema, psoriasis, and acne
What is the primary function of continuous monitoring stations?
To constantly monitor air quality by drawing air in through a tube and automatically transmitting the data.
What type of analysis is performed on the filters or canisters collected from non-continuous stations?
Chemical and/or gravimetric (weight) analysis
What is the purpose of mobile monitors?
To assess ambient air quality over short periods of time in areas not covered by the permanent monitoring network, or for special studies.
What is the name of the Ministry of Environment's mobile air monitoring laboratory?
Mobile Air Monitoring Laboratory (MAML)
How often are the filters or canisters collected from non-continuous stations?
After a discrete period of time (e.g. 24 hours)
Test your knowledge on air pollution and its primary pollutants like methane, non-methane, particulate matter, persistent free radicals, and toxic metals such as lead and mercury. Learn about the impact of these pollutants on the environment and human health.
