Environmental Chemistry

Carbon cycle Photosynthesis stores C in terrestrial and ocean biosphere Respiration releases CO2 back to atmosphere In order to allow build up of free O2, must not allow organic C to decay

Oxygen produced in photosynthesis is consumed by reactions with reduced Fe and S from lithosphere: 2 FeS2 + 15/2 O2 + 4 H2O  Fe2O3 + 4 H2SO4

CO2 is increasing due to fossil fuel combustion CH2O + O2  CO2 + H2O

Atmospheric O2 trend If CO2 is increasing, O2 should be decreasing
