What is composed of fibers known to cause lung disease?

Asbestos

What is a potential human health effect most likely to be associated with a thermal inversion?

Asthma

What is the human health impact most closely associated with atmospheric particulates?

Asthma

The danger from radon gas would most likely be greatest in what situation?

Basement or crawl space

What pollutant has a stronger affinity for hemoglobin than oxygen has?

Carbon monoxide

In the figure below, the letters A, B, C, and D represent the different thermal layers present in an inversion.What is the correct sequence of thermal layers as one moves vertically upwards from the surface of Earth?

Cool sea breeze → Warm → Cool

Which cities regularly experience the worst levels of photochemical smog that is enhanced by thermal inversions?

LA, los angeles

What pollutant is found in old plumbing pipes and fixtures and some ceramic glazes?

Lead

What pollutant is colorless, odorless gas that is a naturally occurring decay product of uranium?

Radon

The major source of radon in houses in the United States is what?

The main source of indoor radon is radon gas infiltration from soil into buildings.

What is a problem that is associated with a thermal inversion?

The stale air of an inversion allows for the buildup of pollutants created by vehicles, factories, fireplaces, and wildfires. These pollutants most often affect those with health problems such as asthma, but particularly unhealthy air can lead to respiratory problems even in folks without preexisting conditions.

A student is setting up a model to study the carbon cycle and natural sources of carbon dioxide. They create a microenvironment that contains soil, leaf debris, an earthworm, heterotrophic bacteria, and a sun lamp. What natural source of carbon dioxide and major metabolic process was left out of the model?

There is no representation of photosynthesis in the model environment.

What pollutant is emitted from most manufactured building materials and furniture?

Vocs such as Formaldehyde, asbestos, radon gas, and mold

What sources should be examined in a study to determine the impact of a geologic source on levels of CO2 in the atmosphere?

Volcanoes

What is an appropriate remediation strategy for removing radon gas from the home?

What is an appropriate remediation strategy for removing radon gas from the home?

What is a natural source of atmospheric carbon dioxide?

decomposition, ocean release, and respiration.

What are the consequences of indoor air pollutants?

irritation of the eyes, nose, and throat. Headaches, dizziness, and fatigue. Respiratory diseases, heart disease, and cancer.

What is a natural process that adds carbon dioxide to the atmosphere?

organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt respiration

What pollutant has been implicated as the cause of as much as 15 percent of lung cancer cases?

radon
