NOA: Naturally Occurring Asbestos Naturally occurring asbestos (NOA) is a relatively recent focus of study and debate. The term "NOA" usually refers to the silicate minerals serpentine and amphibole that are present naturally in rock. If asbestos deposits in the ground or in rock ? the most common sources of NOA ? are left undisturbed, they may not present a significant health hazard.
When NOA Is Disturbed It is when NOA deposits are disturbed that they may give off the carcinogenic fibers that initiate asbestos diseases such as , asbestosis and lung cancer. Among the many ways that a deposit of NOA may be disturbed are:
?Mining ?Quarrying ?Evacuation for the construction of a building ?Farming ?Landscaping ?Gardening ?Shoveling or raking gravel that contains asbestos ?Recreational activities that disturb the soil ? e.g., ATVs, bicycles, jogging
Regarding the last item, recreational activities, it is known that the trailing members of a group of runners, cyclists or vehicle riders are exposed to much higher levels of toxins in the soil compared to the leaders, and that children may suffer from the asbestos exposure more so than adults.
Naturally Occurring Asbestos in Your Community If a community has confirmed that one or more naturally occurring asbestos deposits are present within its confines, several issues arise, including:
?Whether to remove the NOA, and how to do so ?How to reconcile the differing interests of residents, scientific experts, commercial interests, government agencies, etc. ?Possible reduction in property values ?Health concerns ?Employment changes
Harmful Affects of Asbestos Exposure While naturally occurring asbestos mines are not harmful, once disturbed, they become extremely toxic and can lead to the development of asbestos cancers. Asbestos is made up of strands of durable fibers that if broken down, separate, creating a form of dust that can be easily swallowed. If swallowed, the fibers can become embedded in the lungs and over time create irritation, and eventually lead to the development of fatal diseases such as asbestos cancer.

The naturally occurring terpenoid lipids in animals, plants, and fungi, Steroids are often classified into animal steroids, insect steroids, ecdysteroids, vertebrate steroids, steroid hormones, plant steroids, and fungus steroids. Steroids are found in human beings in the form of steroid hormones, which are further classified as sex steroids, corticosteroids, and anabolic steroids.
Sex steroids are the sex hormones that play important role in creating sex differences and reproduction in humans. They include estrogen or oestrogen, progesterone and testosterone. Oestrogen and progesterone are produced primarily in the ovary and placenta during pregnancy and testosterone is mainly produced in the male testes. Corticosteroids including glucocorticoids and mineralocorticoids are responsible in regulating many aspects of metabolism and immune function.
Anabolic steroids are the most well known steroids. Occurring naturally in human bodies, anabolic steroids play key role in the growth genitals, body muscles, and bones. However, anabolic steroids are also produced synthetically. The synthetically produced anabolic steroids are produced as anabolic steroid drugs or medications.
Synthetically produced anabolic steroids are also known as anabolic-androgenic steroids or AAS. They are actually steroid hormones associated with the hormone testosterone, a strong androgenic hormone produced chiefly by the testes, and it is responsible for the development of male secondary sex characteristics. The main function of anabolic steroids is protein synthesis within cells, which helps in building up of cellular tissue (anabolism), especially in muscles. These steroids also play androgenic and virilizing role. They help in the development and maintenance of masculine features, such as the growth of the vocal cords and body hair.
Thus, anabolic steroids are medically used to enhance bone growth and appetite, to stimulate male puberty, and to treat many chronic wasting diseases, such as AIDS and cancer. They are often used to increase muscle mass and physical strength. However, the synthetic anabolic substances are widely used as performance enhancing drugs. They are extensively used, abused, overused in sports and bodybuilding to increase strength or physique.
However, there are several serious health risks associated with excessive and long term use of anabolic steroids. Some of the side effects linked with anabolic steroid use include adverse changes in cholesterol levels – increase in LDL (Low Density Lipoprotein) and decrease in HDL (High Density Lipoprotein), severe acne, hypertension, liver damage, and deadly changes in the structure of the left ventricle of the heart.
