Toxic gaseous element (8)

Ross

I believe the answer is:

chlorine

(Other definitions for chlorine that I've seen before include "It's used to purify a swimming pool" , "Pale green gas" , "It's used to purify water" , "Halogen gas, Cl" , "Gas used in STERILISING water and in industry (8)" .)

I've seen this clue in The Times.
