Does perlite play a role in fluoride toxicity of floricultural crops?

Symptoms of fluoride toxicity include chlorosis of leaf tips and margins which eventually become necrotic. Perlite has been proposed as a source of fluoride. The soluble fluoride contents of 5 samples of perlite (1 from Greece, 2 from New Mexico, 1 from California and 1 of unknown origin) were determined to be in the range 0.05-0.83 ppm.Fluoride is ubiquitously present throughout the world. It is released from minerals, magmatic gas, and industrial processing, and travels in the atmosphere and water. Exposure to low concentrations of fluoride increases overall oral health. Consequently, many countries add fluoride to their public water supply at 0.7–1.5 ppm. Exposure to Principles of fluoride toxicity and the cellular response: a review

Aluminium alleviates fluoride toxicity in tea (Camellia sinensis

Background and aims Tea is a strong accumulator of both aluminium (Al) and fluoride (F). We tested the hypothesis that Al helps detoxify F in tea plants by forming Al-F complexes. Methods Tea plants were grown hydroponically with a range of Al and F concentrations and in a soil pot experiment with amendments of NaF and acids. Growth For many gardeners, perlite plays a key role in improving soil drainage and aeration. Made from transformed volcanic glass, perlite is the small, white balls often found in potting soil and seed-starting mixes. While perlite is a great soil additive, it can cause fluoride burn. On houseplants, this usually appears as brown tips.Perlite Soil What is Perlite and Why Use It? Gardens Alive
