EVR 1001 Lecture Notes - Lecture 30: Bromine, Fluidized Bed Reactor, Smog
Document Summary
Air pollution: chemicals, particulate matter, or microorganisms in the atmosphere at concentrations high enough to cause harm. Air pollutants are found throughout the entire global system: california has pollution problems from china, for example. Major air pollutants: sulfur dioxide (acid rain), nitrogen oxide (fossil fuel combustion), carbon oxides (global warming), particulate matter, volatile organic compounds (vocs), ozone (o3), lead (affects brain function), mercury (kills aquatic organisms) Primary pollutants: pollution compounds coming directly out of smoke stacks, exhaust pipes, or natural emission source (co, co2, no2, etc. ) Secondary pollutants: pollutants transformed in the presence of sunlight, water, oxygen, or other compounds (so3, o3, no3, etc. ) Particulate matter in lungs can cause black lung disease or other health problems, and can cause haze in the air. Some would argue that a city has to have a stronger economy to reduce air pollution effectively.
