Fluorine content of citrus leaves in the major citrus areas of California

; ; ; ;
A survey of the major citrus areas of California was undertaken to establish the extent to which citrus foliage is contaminated by fluoride as a result of air pollution. Leaf samples collected from non-industrial areas served as a basis for comparison. Approximately 130 different orange groves were sampled for fluoride analyses during the summers of 1952 and 1953. In addition, 12 groves were sampled throughout the year to determine the build-up of fluoride over a nine-month period. Data show that there were two general areas having considerably elevated levels, Los Angeles and Fontana. In the neighborhood of Fontana, where a steel plant is located, a maximum of 211 ppm F was observed in one grove and the average content of a dozen groves in the vicinity was 95 ppm F. Data also show an increase in levels over time with greater increases during the July-to-October interval than during the January-to-March interval. The 1 to 2 ppm F in citrus removed from atmospheric pollution categorizes citrus as a poor accumulator when an atmospheric source of fluoride is absent. 4 tables.
