Chapter 9 Air Pollution P 58 divers(prenominal) pollutants hv assorted quotations Find out the sources of different pollutants!!! P61 There ar ozone pile up and depletion~ P71 Normal: pH 7 (neutral), normal come see pH: 5-6, a bit tartic Sources of tartic raining: SO2, NOX(X=123), from industrial activities H2SO4 and HNO3 be strong acidic-> acid rain gas-> +O2 (air is highly oxidized, dozens of radicals)-> acid-> proton-> moisture deposition-> fault/land-> CYCLE (environmental behavior) P72 Apart from natural sources, on that point are artificial process producing SO2, NOX P73 Sea water-> alkaline-> no too more variation, nearly constant WHY serious?? OCEAN ACIDIFICATION?? Rain water-> acidic-> john change a lot->in lake, there are variations P74 Acid raining: the pH of rain in lower than 5.5 (acid precipitation) ?Serious in China (about 90% of cities in China save acid rain problem ? eastbound of US, the pH is in truth low, even 4.2( P76), it s very acidic, mismatched distribution ?West -> normal raining (coz 5.

6) ?Overall, most regions mystify acid rain** P77in all countries, not provided the industrialized countries, hv the acid rain problem Acid rain-> effect timber-> mark proceed acidic-> so, acidic demesne is not suitable for forest emersion Lake (fresh water system): more sensitive to pH change, dont have regulation in pH, so, if protons is added to lake-> pH in lake ordain be lower (primary pollutants) Acid deposition in the soil will bring a lot of chemical reactions - emergence inputs of ions into the lake system, eg, Ca, Mg (secondary pol lutants) -Increase the trace metals to the ! lake (toxic to lake) (secondary pollutants) -Introduce another source of pollutants into the lake system ? leatherneck system (eg, ocean) can regulate the change in pH P78 Leach heavy metals: secondary pollutants Clear, blue lake-> not healthy, elbow grease acidic, less organisms in the lake P79 in China, many buildings are acidified~ disgrace by acid rain P80 OCEAN!
