Examples of Environmental Health Hazards. Those people who live near Superfund sites may be at risk for exposure to hazardous substances in contaminated drinking water, contaminated soil in such areas as playgrounds and gardens, or through the siting of homes on contaminated property with the possibility of exposure to toxic substances via numerous routes and pathways.

The characteristics of chlorofluorocarbons an environmental hazard

A well whose use has been permanently discontinued or which is in a state of such disrepair that it cannot be used for its intended purpose. Reducing the degree or intensity of, or eliminating, pollution. Waste from remediation activities. The uptake of waterother fluids, or dissolved chemicals by a cell or an organism as tree roots absorb dissolved nutrients in soil.

Any of the exchange sites of the body that permit uptake of various substances at different rates e. The location of an unexpected occurrence, failure or loss, either at a plant or along a transportation route, resulting in a release of hazardous materials.

The characteristics of chlorofluorocarbons an environmental hazard

The physiological and behavioral adjustments of an organism to changes in its environment. A corrosive solution with a pH less than 7. Acidic liquid or solid particles small enough to become airborne. High concentrations can irritate the lungs and have been associated with respiratory diseases like asthma.

A complex chemical and atmospheric phenomenon that occurs when emissions of sulfur and nitrogen compounds and other substances are transformed by chemical processes in the atmosphere, often far from the original sources, and then deposited on earth in either wet or dry form.

Classifying Hazards

The wet forms, popularly called "acid rain," can fall to earth as rain, snow, or fog. The dry forms are acidic gases or particulates. Drainage of water from areas that have been mined for coal or other mineral ores. The water has a low pH because of its contact with sulfur-bearing material and is harmful to aquatic organisms.

Measure of ability of a base e. Same as acid deposition Acidic: The condition of water or soil that contains a sufficient amount of acid substances to lower the pH below 7. Regulatory levels recommended by EPA for enforcement by FDA and USDA when pesticide residues occur in food or feed commodities for reasons other than the direct application of the pesticide.

As opposed to "tolerances" which are established for residues occurring as a direct result of proper usage, action levels are set for inadvertent residues resulting from previous legal use or accidental contamination. In the Superfund program, the existence of a contaminant concentration in the environment high enough to warrant action or trigger a response under SARA and the National Oil and Hazardous Substances Contingency Plan.

A highly adsorbent form of carbon used to remove odors and toxic substances from liquid or gaseous emissions.

In waste treatment, it is used to remove dissolved organic matter from waste drinking water. It is also used in motor vehicle evaporative control systems. Product that results when primary effluent is mixed with bacteria-laden sludge and then agitated and aerated to promote biological treatment, speeding the breakdown of organic matter in raw sewage undergoing secondary waste treatment.Environmental Health study guide by wes_capps includes questions covering vocabulary, terms and more.
