residue: A remnant or materials that’s left behind after one thing has been eliminated. As an illustration, residues of paint could stay behind after somebody makes an attempt to sand a chunk of wooden; or sticky residues of adhesive tape could stay on the pores and skin after a bandage is eliminated; or residues of chemical compounds could stay within the blood after publicity to a pollutant.

danger: The possibility or mathematical probability that some dangerous factor may occur. As an illustration, publicity to radiation poses a danger of most cancers. Or the hazard — or peril — itself. (As an illustration: Amongst most cancers dangers that the individuals confronted have been radiation and ingesting water tainted with arsenic.)
