| 686575253 | Acute Effect | the effect caused by a short exposure to a high level of toxin | |
| 686575254 | Catalytic Converter | a platinum-coated device that oxidizes most of the VOCs and some of the CO that would otherwise be emitted in exhaust, converting them to CO2 | |
| 686575255 | Closed Loop Recycling | when materials, such as plastic or aluminum, are used to rebuild the same product. Example would be the use of the aluminum from aluminum cans to produce more cans | |
| 686575256 | Chronic Effect | an effect that results from long term exposure to low levels of toxin | |
| 686575257 | Deep Well Injection | drilling a hole in the ground that's below the water table to hold waste | |
| 686575258 | Dose Response Analysis | a process in which an organism is exposed to a toxin at different concentrations, and the dosage that causes the death of the organism is recorded | |
| 686575259 | Dose Response Curve | the result of graphing a dose-response analysis | |
| 686575260 | ED 50 | the point at which 50 percent of the test organisms show a negative effect from a toxin | |
| 686575261 | Gray Smog (Industrial Smog) | smog resulting from emissions from industry and other sources of gases produced by the burning of fossil fuels | |
| 686575262 | Heat Islands | urban areas that heat up more quickly and retain heat bettern than nonurban areas | |
| 686575263 | LD 50 | the point at which 50 percent of the test organisms die from the toxin | |
| 686575264 | Leachate | the liquid that percolates to the bottom of a landfill | |
| 686575265 | Non Point Source Pollution | pollution that does not have a specific point of release | |
| 686575266 | Open Loop Recycling | when materials are reused to form new products | |
| 686575267 | Photochemical Smog | usually formed on hot sunny days when nitrogen compounds, VOCs, and ozone combine to form smog | |
| 686575268 | Point Source Pollution | specific location from which pollution is released; an example of a point source location is a factory | |
| 686575269 | Primary Pollutants | pollutants that are released directly into the lower atmosphere | |
| 686575270 | Primary Treatment | when physically treated sewage water is passed into a settling tank, where suspended solids settle out as sludge; chemically treated polymers may be added to help the suspended solids separate and settle out | |
| 686575271 | Risk Assessment | calculating risk, or the degree of likelihood that a person will become ill upon exposure to a toxin or pathogen | |
| 686575272 | Risk Management | using strategies to reduce the amount of risk | |
| 686575273 | Secondary Pollutants | Pollutants that are formed by the combination of primary pollutants in the atmosphere | |
| 686575274 | Secondary Treatment | the biological treatment of wastewater in order to continue to remove biodegradable waste | |
| 686575275 | Sludge | solids that remain after the secondary treatment of sewage | |
| 686575276 | Sludge Processor | a tank filled with aerobic bacteria that's used to treat sewage | |
| 686575277 | Stationary Sources | non-moving sources of pollution, such as factories | |
| 686575278 | Superfund Program | a program funded by the federal government and a trust that's funded by taxes on chemicals; identifies pollutants and cleans up hazardous waste sites | |
| 686575279 | Threshold Dose | the dosage level of a toxin at which a negative effect occurs | |
| 686575280 | Vector | the carrier organism through which pathogens can attack, such as a tick | |
| 686575281 | Wastewater | any water that has been used by humans. This includes human sewage, water drained from showers, tubs, sinks, dishwashers, washing machines, water from industry, and storm water runoff | |
| 686575282 | Waste to Energy Program | when energy released from incinerators is used to generate electricity | |
| 686575283 | Green Tax | fiscal policy that lowers tax on income, including wages and profit, and raises taxes on consumption, particularly the unsustainable consumption of non renewable resources | |
| 686575284 | Market Permits | when companies are allowed to buy permits that allow them a certain amount of discharge of substances into certain environmental outlets. if they can reduce their amount of discharge, they are allowed to sell the remaining portion of their permit to another company |
