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.

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.

Health Effects of Mercury
Mercury is a devastating neurotoxin that has signficant health consequences in the United States and across every other developed country. Where there is any type of industry there is usually a risk of higher mercury levels effecting every envirnoment. Learn more about how mercury gets into the environment, what the health impacts are, and how to protect yourself from mercury poisoning.

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 Effects of Coal Combustion In China
Coal is a fossil fuel and when burned in factories it creates massive amounts of smoke that can be harmful to human health. This web page will explain and educate the effects of coal combustion in areas of China where it has become an issue.

Radiation and Nuclear Health Hazards
When we think of radiation we may immediately think of only dangerous and harmful things. In reality, the word radiation refers to any transfer of energy through space from a source. Some examples of radiation include sunlight, radio waves, x-rays, heat, alpha, beta, gamma ionizing radiation, and infrared, just to name a few. Not all of these types of radiation are harmful, in fact, in moderation, most radiation will not pose a health risk. Certain types of radiation, however, can be dangerous, even in small doses.

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.

Airborne Dust Particles
Airborne dust is particle, or Particulate Matter (PM), pollution, and is one of the most significant air pollutants in Pima County. PM is made up of tiny solid particles or liquid droplets (a fraction of the thickness of a human hair) that float in the air we breathe. Because they are so small, you cannot see individual particles, but you can sometimes see the haze that is formed when millions of particles blur the spread of sunlight.

Chromium and its negative effects on the environment
Chromium comes in a plethora of forms and shapes in nature; it is a naturally occurring element (Atomic Mass #24), and can be both helpful and harmful to human health and the environment.

Agricultural Pesticides and Human Health
A pesticide is any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any pest ( Pests can be defined as any organism that causes plant diseases. Agricultural pesticides are then those chemicals that are used by farmers to prevent the effectivity of the pests on the growth and productivity of agricultural crops.

Airborne Microbes
In order to educate you about airborne microbes in different environments, I will let you know a little bit about when, where and how you can find these little, microscopic buggers and what kind of affect they'll have on you or your family. Everyone has their own natural microorganisms that live on, in and around their own bodies. These bacteria are known as natural flora and our own bodies (specifically the immune system) recognize that they are good for us. We, as humans, would not survive without such creatures. However, this website gives information regarding pathogenic microorganisms in general. That is, things that you can't see causing physical harm.
