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.
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.
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.
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.
Radiation and Cancer
This web page provides information about the different types of radiation, where they come from, how they can impact your health, and what you can do to lower your chances of radiation exposure.
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.
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.
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.
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.
