Acrylamide is a chemical widely used during the manufacturing of paper, dye, and other industrial products. It can also be formed when certain foods are cooked at high temperatures. Frying, baking, or roasting certain foods, such as potatoes or grains, can create acrylamide. French fries and potato chips, for example, may have measurable acrylamide levels. Acrylamide is also found in cigarette smoke.

Climate change endangers human health, affecting all sectors of society, both domestically and globally. The environmental consequences of climate change, both those already observed and those that are anticipated, such as sea-level rise, changes in precipitation resulting in flooding and drought, heat waves, more intense hurricanes and storms, and degraded air quality, will affect human health both directly and indirectly

There is abundant evidence that human activities are altering the earth’s climate and that climate change will have significant health impacts both domestically and globally. While all of the changes associated with this process are not predetermined, the actions we take today will certainly help to shape our environment in the decades to come.

Asbestos is a mineral fiber that occurs in rock and soil. Because of its fiber strength and heat resistance, asbestos has been used in many materials produced for building or home construction, particularly if they were manufactured prior to 1980, such as shingles, ceiling and floor tiles, and attic and pipe insulation. If these materials are broken, crushed, or disturbed, the asbestos fibers may be released into the air and become a health hazard. High exposures to asbestos may occur during demolition and rebuilding.

Asthma is an inflammatory disease of the lung. This inflammatory process can occur along the entire airway from the nose to the lung. Once the airway becomes swollen and inflamed, it becomes narrower, and less air gets through to the lung tissue. This causes symptoms like wheezing, coughing, chest tightness, and trouble breathing. During an asthma attack, the muscles around the airways tighten up and the asthma symptoms become even worse than usual.

Research has shown that environmental factors likely play a role in autism. Studies also indicate that genetics contribute to the disorder. The National Institute of Environmental Health Sciences (NIEHS) supports research to discover how the environment may influence autism. This important environmental research offers real promise for prevention — because you can’t change your genes, but you can change your environment.

Autoimmune diseases result from a dysfunction of the immune system. The immune system protects you from disease and infection. Sometimes, though, the immune system can produce autoantibodies that attack healthy cells, tissues, and organs. This can lead to autoimmune disease.
