John Hunt, 28, of Armidale worked as a carpenter and was frequently exposed to the OC pesticides aldrin and heptachlor which were routinely used on building sites. He also cleaned out barley silos for four months over a two year period. The stored cereal was fumigated with pesticides and residues remained after treatment. John now suffers from giddiness, restlessness, fatigue, muscle twitching, sweating, breathing difficulties, hypoglycemia and allergies. These symptoms first became apparent when he was 21 and still persist eight years later. p43 Quick Poison Slow Poison. Pesticide Risk in the Lucky Country. Kate Short 1994
