Air and Atmosphere

effects of acid rain:

• acidification of lakes cause loss of marine organisms

• acid rain destroys roots and causes nurtients to leach out of soil. leads to deforestation

• reacts with marble and limestone buildings: corrodes building

reducing effect of acid rain:

• fix vehicle exhaust with catalytic converter

• flue gas desulfurisation reduce emission of SO2 into atmosphere

• liming soil and water bodies (temporary effects only)

how catalytic converters work:

platinum and rhodium catalysts

when exhaust gas pass over catalysts, harmful pollutants are converted to harmless substances

CO→ CO2

NO2 → N2 + 2O2

H2 → H2O
