Thirty years ago, on 13 June 1991, a major international meeting convened to address how to eliminate the poisoning of waterbirds with toxic lead gunshot.  Shot is deposited on the ground whenever it is used and subsequently kills when it is consumed by waterbirds.  The conference was organised by the International Waterbirds and Wetlands Research Bureau (now Wetlands International) and its aim was to review the extent of the problems of lead poisoning throughout the world and identify possible solutions.
