Gypsum is a relatively common mineral that is widely available in agricultural areas and has a number of specialized agronomic uses, principally as a Ca source on legumes and as a soil conditioner on sodic soils. Gypsum is formed when, due to evaporation, sulfur present in water bonds with oxygen to form a sulfate. The chemical formula of Gypsum is CaSO4 ∙ 2H2O (Calcium Sulfate Dihydrate). During particle-size analysis of soils containing gypsum the soil suspension usually flocculates partially or totally after a period of time, because of the calcium ions released from the gypsum. The industry adheres to very strict quality controls for the manufacture or disposal of UK plasterboard. From a chemical point of view it is Calcium Sulphate Dihydrate ( CaSO 4.2H 2O) deposited in sedimentary layers on the sea bed.

Since the concentration levels of the analites are different Cd, Th and U concentration are presented in Figure 2. Type X Gypsum Board – a gypsum board with special core additives to increase the natural fire resistance of regular gypsum board. Al Ahli micronized gypsum is produced with special size distribution and physical –chemical properties, according to international standards. Scanning electron microscopy (SEM) analysis in combination with an energy dispersive X-ray analyzer (EDXRA) has been used to study microfabrics of soils with gypsum, after gold-metallization, as well for chemical analysis (Herrero, 1987; Poch, 1992). For example, gypsum may contain trace amounts of naturally occurring metals, and other silicates.
