| carbon monoxide and nitrogen oxide are produced by the car engine. it converts harmful nitrogen gaese to CO2 and H20 which become the only emissions |
|
|
Term
|
Definition
| when somehting at a factory burns the emmision will contain nitrogen oxides, carbon oxides, and sulfur oxides. Scrubbers spray a liquid sorbent and when they combine with the oxides the chemical reaction will result in a solid the emissions then have no nitrogyn or sulfur oxides |

| what does algae growth cause |
|
Definition
| makes the water cloudy and reduces oxygen content |
|
|
Term
|
Definition
| Lots of nitrates in the water shows that there is decomposition happening. Algae growth skyrockets. This is often because of excess phosphates and nitrates (from sewage and agricultural run-off). Eventually, the algae dies, and decomposition of the algae leads to low oxygen levels. This may lead to death or injury to aquatic animals. The excess algae also cause the water to warm up because when the sun hits the algae it traps the heat causing lower oxygen levels. |
