Fluoride damage to woody vegetation in New Jersey in 1974

OSTI ID:6331262
In the course of a 2-year survey to assess the impact of air pollution on trees in New Jersey, two incidents of severe damage to woody plants by fluorides emitted from specific industrial sources were documented. Classic fluoride toxicity symptoms were observed on plant species that are generally regarded as sensitive, and also on several species of oak. The symptom on pine was unusual in that a dark band delimiting the necrotic area on the needle appeared 3-4 weeks after the initial injury occurred. Douglas-fir and peach trees that were defoliated by the pollutant put out a second flush of growth. Among the species exhibiting extreme resistance to fluoride damage were American holly, white birch, London plane, flowering dogwood, magnolia, mulberry, apple, and Norway maple.
