TABLE OF CONTENTS
- Occurring over a short time [compare with chronic].
- Agency for Toxic Substances and Disease Registry (ATSDR):
- The principal federal public health agency involved with hazardous waste issues, responsible for preventing or reducing the harmful effects of exposure to hazardous substances on human health and quality of life. ATSDR is part of the U.S. Department of Health and Human Services.
- An underground formation composed of materials such as sand, soil, or gravel that can store and/or supply groundwater to wells and springs.
- Occurring over a long time (more than 1 year) [compare with acute].
- A substance that is either present in an environment where it does not belong or is present at levels that might cause harmful (adverse) health effects.
- Dermal Contact:
- Contact with (touching) the skin (see route of exposure).
- Environmental Protection Agency (EPA):
- United States Environmental Protection Agency.
- Contact with a substance by swallowing, breathing, or touching the skin or eyes. Exposure may be short-term [acute exposure], of intermediate duration, or long-term [chronic exposure].
- Water beneath the earth's surface in the spaces between soil particles and between rock surfaces [compare with surface water].
- Hazardous substance:
- Any material that poses a threat to public health and/or the environment. Typical hazardous substances are materials that are toxic, corrosive, ignitable, explosive, or chemically reactive.
- Indeterminate public health hazard:
- The category used in ATSDR's public health assessment documents when a professional judgment about the level of health hazard cannot be made because information critical to such a decision is lacking.
- The act of swallowing something through eating, drinking, or mouthing objects. A hazardous substance can enter the body this way [see route of exposure].
- The act of breathing. A hazardous substance can enter the body this way [see route of exposure].
- Monitoring wells:
- Special wells drilled at locations on or off a hazardous waste site so water can be sampled at selected depths and studied to determine the movement of groundwater and the amount, distribution, and type of contaminant.
- No apparent public health hazard:
- A category used in ATSDR's public health assessments for sites where human exposure to contaminated media might be occurring, might have occurred in the past, or might occur in the future, but where the exposure is not expected to cause any harmful health effects.
- No public health hazard:
- A category used in ATSDR's public health assessment documents for sites where people have never and will never come into contact with harmful amounts of site-related substances.
- Compounds composed of carbon, including materials such as solvents, oils, and pesticides that are not easily dissolved in water.
- Route of exposure:
- The way people come into contact with a hazardous substance. Three routes of exposure are breathing [inhalation], eating or drinking [ingestion], or contact with the skin [dermal contact].
- Surface Water:
- Water on the surface of the earth, such as in lakes, rivers, streams, ponds, and springs [compare with groundwater].
- Volatile organic compound (VOC):
- Organic compounds that evaporate readily into the air. VOCs include substances such as benzene, toluene, methylene chloride, and methyl chloroform.
