Geology and Human Health Case Studies Collection

These case studies were developed by students in the 2012 introductory-level Geology and Human Health course offered by the Department of Earth Sciences at Montana State University. This course is offered for non-geoscience majors and counts for our Core Curriculum credit in the Contemporary Issues in Science rubric.

Asbestos in the Home
This web page it designed to provide easy access to information about asbestos in order to spread awareness. Asbestos has become a major environmental health hazard. It has been used in many industrial and commercial products that can be found in the home and in the place of work. When asbestos is inhaled it causes sever damage to the lungs which can lead to major health problems including emphysema and, in cases of high exposure, lung cancer.

Volcanic Ash: More Than Just A Science Project
The term "volcano" has its origin from the name of Vulcan, the Roman god of fire. However, volcanoes are a result of processes of the earth much older than Roman mythology. While volcanoes may be fun to construct for science class or watch on television, the real consequences of volcanic eruptions can be harmful and serious. Some of these consequences include fires, structure damage, and differences in climate. One of the most deadly effects of a volcano is the ash coming from the eruption, which carries poisonous gases that are harmful to humans, plants, and animals alike.

What Will Climate Change Mean for Lyme Disease?
The first case of Lyme disease to be reported in the United States was in the town of Lyme, Connecticut, in 1975. The disease is caused by a bite of a deer tick (Ixodes scapularis) leading to a bacterial infection (Borrelia burgdorferi). With the impending changes to the climate, scientists expect to see the reported cases of Lyme disease to increase, as well as the disease to be able to occur in areas it previously had not. Arming yourself with knowledge of the signs and symptoms of the infection is paramount for those who spend time outdoors.

Smoke and Ash Inhalation Related to Wildfires
The number one cause of death when it comes to fires is smoke inhalation. Smoke inhalation damages the body by asphyxiation (lack of oxygen), chemical irritation, or a combination of the two. Smoke itself can be harmless to you but it takes up the space needed for oxygen, similar to carbon dioxide. Smoke inhalation is especially dangerous because people may not show symptoms until 24 to 48 hours after the event. An estimated 50-80% of fire deaths are from inhalation, not burns.

Health Effects of Radon
Radon is a naturally caused radioactive gas that can infiltrate your home. Knowing where radon comes from and how it gets into your home can help protect you from its negative health effects.

Asbestos at Thetford Mines, Quebec Canada
After being the focal point for the economies of nations such as Canada for a century, the asbestos industry looks to be all but dead. The health hazards that this silky-white product presents are now seen to outweigh the benefits of its fire, rust, and rot resistance, tensile strength, and sound absorption.

Plastics in the Ocean Affecting Human Health
Over a few decades, humans have managed to dump tons upon tons of garbage into the ocean. Of the most devastating elements of this pollution is that plastics takes thousands of years to decay. As a result, fish and wildlife are becoming intoxicated. Consequently the toxins from the plastics have entered the food chain, threatening human health. In the most polluted places in the ocean, the mass of plastic exceeds the amount of plankton six times over. This is a large piece of evidence that leaves the problem of polluted oceans undeniable. It is upsetting that more of clean up effort is not taking place.

Health Hazards from Mining in Butte, Montana
Butte, Montana was once know as "the richest hill on earth" for it's historical extensive mining industry. The area has now transformed into the nation's largest superfund site after much of the mining was shut down and the Berkeley Pit filled up with acidic groundwater with high concentrations of hazardous heavy metals.

Nuclear Mitigation Measures at the Department of Energy's Hanford Nuclear Site
Since humans first started working with nuclear processes, we have had the problem of safely storing and containing the tailings of these. The Hanford Site, ran by the Department of Energy, has thought of and is currently building a 65 acre facility to take care of this very large problem.

Health Effects from British Petroleum Oil Spill
The British Petroleum oil spill made history on April 20, 2010. An explosion on the drilling platform caused the oil rig to begin sinking and as the oil rig sunk, millions of gallons of oil began dissipating into the Gulf of Mexico with no way to try and stop it. As the oil continued to leak out into the open ocean, not only sea life became endangered, human health did as well. Once the ocean became polluted with oil, it was only a matter of time until the effects began weighing on human health.
