How does chlorine affect material over a long period of time? How does chlorine affect peoples’ health?
Answer 1:

Chlorine is toxic. People exposed to low concentrations of the gas will experience irritation of the eyes and respiratory system. Higher concentrations (about 1 part per thousand) are fatal.


Answer 2:

Chlorine is poisonous. This is why the presence of chlorine cleans things: it kills bacteria and algae that would otherwise soil them. Fortunately for us, our bodies are so large relative to bacteria that the small amounts of chlorine that we are exposed to isn't enough to do us any permanent harm. However, if the only water you had available for you to drink were, say, swimming pool water, you would eventually poison yourself to death.

Chlorine is corrosive to most materials, usually by being acid. However, some things, like glass, are pretty much immune to the corrosive effects of chlorine.
