Bromine, 35, Eastview Secondary School, Barrie ON

Bromine: It seemed appropriate that I should paint this tile in water colours, as bromine is a liquid at room temperature. The halo represents the halogen group. The skull and crossbones are symbolic of bromine’s toxic and poisonous effects. The pills represent medicinal uses of bromine, such as in antiepileptic and sedatives. The insects represent bromine’s association with pesticides and insecticides. The snail and seaweed are organisms which produce organobromides. The green colour represents simple life forms such as algae that produce organobromides. The sand represents the sea floor. The background is reddish brown because that is the colour of elemental bromine.
