Activity 3.3.1 Air Pollution Core Activity
Air Pollution Basics We are exposed to air pollution every day from various sources ( Freedman, Pg.366). Things such as CO2 emissions cars or pollution from overall industrialization. This all began with the industrial revolution around 1750 when coal became the one of the major fuel sources (Freedman, Pg 366). This led to an increase in sulfur dioxide emissions. Air pollution is strongest in atmospheres that are almost stagnant (Freedman, 366). This happens when two separate layers of air, a cool layer is trapped by an underlying hot layer of air (Freedman, Pg. 366). This prevents the two layers from mixing. Keeping polluted air closer to the surface. This is what we think of when we think of smog filled cities from olden times. Especially when considering periods in history such as the industrial revolution. This would cause various respiratory illnesses and even death. In the scientific community this stirred up a...
