The principal factors influencing corrosion in the tower were most likely oxygen ,
hydrogen sulphide , carbon dioxide , algae and bacteria . Chlorine was injected
to control algae and slime but traces of hypochlorous and hydrochloric acids ...

Similarly , changes in oxygen concentrations occur on the metal surface due to a
change in the type of soil and surface conditions . Corrosion occurring by
difference in oxygen concentration is accelerated in areas where the oxygen is ...
