Analyse the information that indicates changes in the atmospheric ozone concentrations.

Uses of CFCs during the mid 1900 (40-80s) CCl3(g) + uv.light -> Cl.(g) + CCl2F(g) Cl.(g) + O3(g)-> ClO(g) + O2(g) – (1) ClO(g) + O.(g) -> O2(g) + Cl.(g) – (2) In comparing (1) and (2)m the Cl. Free

radical is used but reproduced; thus acting like a catalyst.

Therefore Cl. Breaks down O3 (ozone) into 2O2 (oxygen gas) and is reproducedl thus being able to continue reacting with O3.

Analyse the information that indicates changes in the atmospheric ozone concentrations.

Components: Ozone and CFCs. Relationship: CFCs decomposes in uv

light and reacts with O3. Uses: O3 -> block UV-B and C.

› UV-B + UV-C are BAD! › UV-B – skin cancer, eye cataracts,

decreased immune response, damages plants.

› UV-C – even worse

Analyse the information that indicates changes in the atmospheric ozone concentrations.

Analysis on evidence: › Increased in UV-B and UV-C impheatuens. › Decrease in Ozone concentration › Increase in CFC use
