Effects of relative humidity and free water on the phytotoxicity of hydrogen fluoride and cryolite

Effects of relative humidity and free water on the phytotoxicity of hydrogen fluoride and cryolite. McCune, D. C.; Silberman, D. H.; Weinstein, L. H. (Boyce Thompson Inst. Plant Res., Yonkers, N. Y., USA). Proc. Int. Clean Air Congr., 4th, 116-19. Edited by: Kasuga, Susumu; Suzuki, Noboru; Yamada, T. Jap. Union Air Pollut. Prev. Assoc.: Tokyo, Japan. (English) 1977. CODEN: 37PQAB. DOCUMENT TYPE: Conference CA Section: 4 (Toxicology) Mandarin orange (Citrus reticulata) exposed to ￡900 mg F (as cryolite [15096-52-3])/m3 h at 75% relative humidity showed no increase in foliar fluoride. Exposure to 7800 mgF/m3h at 85% relative humidity increased foliar fluoride 3 times while a mist increased foliar fluoride levels 5-fold over an equiv. dose at 85% relative humidity. Neither increasing relative humidity from 75 to 85% nor using a mist affected foliar fluoride after exposure to HF. Spinach accumulated fluoride similarly to mandarin oranges while rice behaved similarly in the presence of cryolite, and a mist increased foliar fluoride by 31% at a dose of 960 mg F/m3h (as HF) in rice. HF caused more injury in all species than cryolite, and relative humidity and mist affected the toxicity.
