我諗有d 部份係咪搞錯左
O3 .... 即係ozone ..... 3 個oxygen atom link 埋的 molecule .... very
unstable ..... can fine in natural environment ..... produce by some plant
O3 is readily to transform to O2 and single O molecules. Single O is a
potent oxidizing agent ---> Kill bactaria or other micro organism readily
Generally not classify as pollutant in daily life coz it is readily to split
into O2 and single O, Under normal situation, not harmful to human or plant
coz there is prime enzymatic action to remove single O
High conc. O3 may damage epithilia cell of all organism, consider the case
of H2O2 ---> H2O + O
Cl2 = 氯氣
