| AIR POLLUTION | CONDITION IN WHICH THE AIR CONTAINS SUBSTANCES HARMFUL TO LIVING THINGS. |
| CARBON MONOXIDE | AN ODORLESS,COLORLESS,POISONOUS GAS PRODUCED BY THE INCOMPLETE BURNING OF FOSSIL FUELS. |
| NITROGEN OXIDE | WHEN COMBUSTION TEMPERATURES EXCEED 538 DEGREES C. NITROGEN AND OXYGEN PARTICLES IN THE AIR COMBINE TO FORM NITROGEN OXIDES. |
| SULFUR DIOXIDE | PRODUCED BY CHEMICAL INSTRUCTIONS BETWEEN SULFUR AND OXYGEN. |
| VOLATILE ORGANIC COMPOUNDS | CHEMICAL COMPOUNDS THAT FORM TOXIC FUMES. |
| PARTICULATES | VERY SMALL, SEPERATE PARTICLES, AS IN SOOT AND ASH. |
| PRIMARY POLLUTANT | POLLUTANT PUT DIRECTLY INTO AIR BY HUMAN ACTIVITY, SUCH AS SOOT FROM SMOKE. |
| SECONDARY POLLUTANT | POLLUTANT THAT FORMS WHEN A PRIMARY OR NATURALLY OCCURRING SUBSTANCE COMES INTO CONTACT WITH OTHER PRIMARY POLLUTANTS TO FORM A CHEMICAL REACTION. |
| THERMAL INVERSION | ATOMOSPHERE CONDITION IN WHICH THE AIR ABOVE IS WARMER THAN THE AIR BELOW, SOMETIMES TRAPPING POLLUTANTS NEAR THE EARTH'S SURFACE. |
| SMOG | AIR POLLUTION OVER URBAN AREAS, THAT REDUCES VISIBILITY. |
| SICK BUILDING SYNDROME | CONDITION OF BUILDINGS WITH PARTICULARY POOR AIR QUALITY FREQUENTLY CAUSED BY SEALED WINDOWS AND POOR AIR CIRCULATION. |
| ACID PRECIPITATION | HIGHLY ACIDIC RAIN, SLEET, OR SNOW THAT RESULTS FROM THE REALEASE OF OXIDES OF SULFUR AND NITROGEN INTO THE AIR FROM BURNING FOSSIL FUELS. |
| ACID SHOCK | SUDDEN INFLUX OF ACIDIC WATER CAUSED BY MELTING ACIDIC SNOWS THAT RUSH INTO LAKES AND STREAMS KILLING LARGE NUMBERS OF FISH AND AMPHIBIANS AND EFFECTING THE OFFSPRING OF OTHERS. |
| OZONE | FORM OF OXYGEN WITH MOLECULES MADE OF 3 OXYGEN ATOMS. |
| OZONE LAYER | LAYER OF UPPER ATMOSPHERE WHERE MOST ATMOSPHERIC OZONE IS CONCENTRATED, SERVING TO ABSORB MUCH SOLAR ULTRA VIOLET RADIATION. |
| RADON GAS | GAS PRODUCED NATURALLY IN THE EARTH BY THE DECAY OF URANIUM. |
| ASBETOS | MINERAL THAT SEPERATES INTO LONG, THREAD LIKE FIBERS, USED FOR INSULATION. |
| ASTHMA | AN ALLERGIC RESPIRATORY DISORDER CHARACTERIZED BY WHEEZING AND DIFFICULTY IN BREATHING. |
| EMPHYSEMA | A CHRONIC LUNG DISEASE CHARACTERIZED BY ABNORMAL ENLARGEMENTS AND LOSS OF ELACTICITY OF THE AIR SPACES. |
| CHRONIC BRONCHITIS | LONG LASTING INFLAMATION OF THE MEMBRANE LINING OF THE BRONCHIAL TUBES. |
| WATER CYCLE | THE CONTINUAL PROCESS IN WHICH WATER CIRCULATES BETWEEN THE ATMOSPHERE AND THE EARTH. |
| WEATHER | CONDITIONS IN THE ATMOSPHERE AT A PARTICULAR PLACE AND TIME. |
| ULTRA VIOLET | HARMFUL LIGHT FROM SUN. |
| CFC'S | CLUROFLUROCARBONS: HAMN MADE CHEMICAL COMPOUNDS RESTRICTED IN USE BECAUSE OF OZONE DESTRUCTION. |
| HYDROCARBON | ANY OF A CLASS OF COMPOUNDS CONTAINING ONLY HYDROGEN AND CARBON, AS METHANE. |
