chemical element for quarry dust

  • Mobilization and redistribution of elements in soils

     · ing element mobilization and redistribution during chemical weathering. In addition laterites the prod-ucts of extreme weathering account for over 85 of the present world soil cover (Nahon 2003). They are readily eroded from profiles and transported into oceans and their chemical compositions may be im-printed into sediments.

    Evaluating the impact of a limestone quarry on suspended

     · Research highlights This study evaluated pollution of dust from a limestone quarry during dry season. Trace element analysis in TSP showed enrichment in elements from industrial sources. Downwind site is enriched in the major component of the quarried rock calcite. Backward trajectory analysis helped determine non-local events influencing TSP.
