Estimated the transport of toxic metals from water to soil and sediment; stressing what renders metals to be toxic is not its total content but speciation forms whether in soil or water. Due to our calcareous soils, these toxic metals will be incorporated in soils and/or sediments and in water speciation as carbonate complexes lowering the toxic metal effects. To render less metal toxicity in Lebanese water bodies’ acid drainage or waste should be banned. Also the risk assessment of phthalate contaminates in children’s toys were estimated. Proposing the banning of manufactured clays to children and substituting it by moulding food products, to avoid heath risk factors.
