Content: When asbestos is inhaled, the fibrous structure of this mineral makes it stick in your lung tissue, and the rest of the body then produces an acid to fight it. The acid scars the lung tissue but doesn't really do much to get rid of the asbestos, and the result is lung cancer or non-functioning lungs. Because we now know the dangers of indoor environmental hazards, there have been great efforts to remove them from our environment. Radon detection kits are available to test homes for the presence of radon gas. Pipes used in new-home construction contain much less lead than in older homes, and most paints are now lead-free. Asbestos is being removed from public buildings, but there are some who think that the exposure from removing asbestos is actually more dangerous than leaving it in place. Lesson Summary
We encounter a number of environmental hazards every day. Environmental health involves understanding all of the physical, chemical, biological and cultural hazards from natural and human-made sources. Physical hazards come from physical processes, which can be discrete events, such as tornadoes, hurricanes, and volcano eruptions, or they can be long-term hazards like UV radiation. Chemical hazards can come from a variety of natural and human-made sources.
