    Notes: [Auszug] Two series of spectrographic analyses have, therefore, been made on the solutions from the usual processing sequence on nuclear plates coated with 200 (JL thickness of emulsion and loaded with natural lithium sulphate and boric acid respectively. It was found that pre-soaking for one hour in ...

    Fluorine and boron effects on vegetation in the vicinity of a fiberglass plant (1978)
    Springer
    Water, air & soil pollution 10 (1978), S. 163-174

    Notes: Abstract Fluorine and B concentrations in foliage and foliar injury symptoms produced by these contaminants closely followed the changing pattern of atmospheric emissions from a fiberglass plant. Typical F injury symptoms on foliage were replaced by B injury symptoms as F emissions were reduced. Foliar concentrations of B in excess of 300 ppm accumulated by plants exposed to atmospheric B emissions produced injury symptoms on sensitive species similar to those produced by toxic concentrations of B absorbed through roots. Water-soluble F and B concentrations in soil decreased with increasing distance from the fiberglass plant. Soluble B concentrations in soil within 150 m of the plant were above levels known to be injurious to many plant species. Water-soluble F in soil in the same area increased the F content of some native plants above 50 ppm by the end of the growing season. Silver maples (Acer saccharinum) growing near the fiberglass plant had delayed growth of new shoots in the spring and had increasingly higher contents of F and B in trunk sap with proximity to the fiberglass plant. Control of F and then B emissions by the company resulted in reduced concentrations of these elements in foliage and a reduction in the degree and extent of vegetation injury around the plant.
