Final answer:
True, asbestos removal must be done by qualified professionals. False, radon is invisible and odorless, detectable only through testing. To reduce exposure to air pollution, detectors for radon and carbon monoxide are recommended in the home.
Step-by-step explanation:
Regarding the question about environmental issues, first, it is indeed true that when a building component containing asbestos is deteriorating, it is necessary to have it removed by qualified professionals. Asbestos can be a significant health hazard, and proper removal is essential to ensure safety. Second, the statement about radon having a distinctive citrus-like odor is false. Radon is an invisible and odorless noble gas. The only reliable method to detect radon levels in a building is through testing, as radon can enter a building through various means such as cracks in floors and walls, construction joints, and gaps around service pipes.
To reduce your exposure to air pollution, in addition to using less toxic chemicals and ensuring proper ventilation, it is also effective to have detectors for radon and carbon monoxide in your home. High radon levels are serious health risks, and exposure has been linked to an increased risk of lung cancer, particularly for nonsmokers.
Statement 1: True. When a deteriorating building component contains asbestos, the only acceptable method to safely resolve the issue is to have qualified professionals completely remove the component. Asbestos is a hazardous material that can cause serious health issues if released into the air.
Statement 2: False. High levels of radon in a building cannot be detected by radon's distinctive citrus-like odor. Radon gas is odorless and colorless, so the only way to know if a building has elevated radon levels is to conduct testing.
