Atmospheric Pollution
What is a potential health effect associated with exposure to Radon-222?
It can lead to no change in respiratory function or risk of cancer
It can lead to respiratory problems and certain cancers
It can lead to occasional respiratory problems, depending on the level of exposure
It can lead to improved respiratory function and reduced risk of cancer
Considering the sick building syndrome, what ventilation strategy could exacerbate the presence of indoor air pollutants?
Using recirculated air exclusively without adequate filtration or fresh-air intake
Installing High-efficiency particulate arrestance (HEPA) filters in the HVAC system
Increasing the number and length of open windows throughout the building
Integrating an energy recovery ventilator (ERV) system for controlled ventilation
Asbestos contamination indoors is primarily associated with which building material?
Detection Systems Detected by Detectives With Disabilities From Deafness To Diabetes
Incorrected Excerpts
Insulation materials from older buildings
Modern vinyl flooring products designed for safety standards compliance
Considering biogenic volatile organic compound (BVOC) emissions, how can urban planning effectively decrease potential contributions to indoor air pollution?
Promoting exclusively man-made structures devoid of vegetation in city designs
Mandating rooftop gardens across urban developments without species selection
Installing mechanical ventilation systems in all urban buildings regardless of cost
Incorporating plant species with lower BVOC emissions in urban greenspaces
What long-term health effect is primarily associated with chronic exposure to fine particulate matter found within many urban households?
Respiratory diseases such as asthma and bronchitis.
Neurological disorders including migraines and dizziness.
Skin irritations including eczema and rashes.
Digestive issues like gastritis or ulcers.
A homeowner wants to minimize her family's exposure to volatile organic compounds (VOCs); which action would be most effective for this purpose?
Installing carpets with tight weaves throughout the home
Frequent use of unvented kerosene heaters
Increasing insulation thickness around pipes
Using paints and varnishes with low or no VOC content
What is a primary environmental disadvantage of using coal as an energy source compared to wind power?
Lower energy efficiency per unit area
Increased noise pollution associated with operation
More land use displacing wildlife habitats
Higher greenhouse gas emissions

Give us your feedback and let us know how we can improve
Which indoor air pollutant is commonly associated with building materials and can cause respiratory issues when inhaled?
Radon
Carbon monoxide
Lead paint
Asbestos
In terms of reducing combustion-related indoor air pollution, what practice should be discouraged in residential settings?
Electric heater utilization which does not emit combustion pollutants directly into homes
Propane stove use with proper venting as it minimizes incomplete combustion products
Installation of fireplace inserts that improve efficiency & reduce particulate matter release
Unvented kerosene heater use due to emissions of carbon monoxide and nitrogen oxides
What regulatory approach could simultaneously help reduce radon levels indoors and provide data for future policy decisions regarding this pollutant?
Instituting voluntary guidelines for new constructions to include radon-resistant features with no enforcement mechanism or data reporting requirement.
Distributing free radon test kits to homeowners without requiring result submission or follow-up action plans if high levels are detected.
Subsidizing radon mitigation systems solely for schools and public buildings without broader application or data collection.
Requiring mandatory radon testing during real estate transactions and submitting results to a national database.
