Eastern white pine (Pinus strobus l.) forests were severely damaged by atmospheric sulfur dioxide up to distances of 25 miles northeast of large smelters located in the Sudbury Mining District of Ontario. Damage to white pine was measured in terms of foliage, bark, and biological injuries, radial and volume growth decrement, and tree mortality. The foliar symptoms of sulfur dioxide injury on white pine trees sometimes resembles those caused by a physiogenic disease, semimature-tissue needle blight (abbreviated to SNB). Studies on the nature and etiology of SNB were conducted in white pine forests in the Upper Ottawa Valley, which are remote from smelter operations which might pollute the atmosphere. These studies include the determination of the role that naturally-occurring atmospheric ozone plays in the occurrence of SNB. Differences between the symptoms of sulfur dioxide injury, SNB, and ozone damage are outlined.
