1996-7-1  The element is also significant in the long-term leaching of coal waste products, including mine overburden, washery refuse and fly ash in land reclamation sites (Howard et al., 1988). The average phosphorus content of coal on a world-wide basis is estimated by Bertine and Goldberg (1971) at 0.05% or 500 ppm.
