Other claims from this paper (6)

Association Mean needle longevity decreased 15–40% toward pollution sources.
Method / resource The first half of gradual shedding was a valid indicator of changes in needle age structure.
Association Needle age structure varied most markedly in slightly polluted areas.
Observation Slightly polluted areas continued to pose a risk of acute pollution injuries.
Method / resource Branch-sample needle age structure was feasible as an objective and reliable Scots pine vitality indicator.
