Chapter 9 Air Pollution P 58 divers(prenominal) pollutants hv diametric quotations Find out the sources of different pollutants!!! P61 There ar ozone amass and depletion~ P71 Normal: pH 7 (neutral), normal come brush up pH: 5-6, a bit tartic Sources of stingingic raining: SO2, NOX(X=123), from industrial activities H2SO4 and HNO3 be strong acidic-> acid rain gas-> +O2 (air is highly oxidized, lot 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, in that respect 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 ? tocopherol of US, the pH is in truth low, ev en 4.2( P76), its very acidic, unmated distribution ?West -> normal raining (coz 5.
6) ?Overall, most regions gather in acid rain** P77in all countries, not provided the industrialized countries, hv the acid rain problem Acid rain-> effect timber-> mark function acidic-> so, acidic stain is not suitable for forest produce Lake (fresh water system): more sensitive to pH change, dont have regulation in pH, so, if protons is added to lake-> pH in lake bless be lower (primary pollutants) Acid deposition in the soil will bring a lot of chemical reactions - exploitation inputs of ions into the lake system, eg, Ca, Mg (secondary pollutants) -Increase! the trace metals to the lake (toxic to lake) (secondary pollutants) -Introduce another source of pollutants into the lake system ? maritime system (eg, ocean) can regulate the change in pH P78 Leach heavy metals: secondary pollutants Clear, blue lake-> not healthy, gravel acidic, less organisms in the lake P79 in China, many buildings are acidified~ disgrace by acid rain P80 OCEAN!
