The effects of chemical time bombs are typically discontinuous and non‐linear. Once a certain threshold has been passed, The system starts to behave differently from before (Stigliani, 1991). a typical example is the consumption of a certain buffer capacity in a system, and the subsequent breakthrough of parameters such as pH values and metal concentrations. the mobilization of metals from different types of waste materials, after the depletion of typical barriers (mechanical or chemical) or after an increase of accelerating factors such as the lowering of pH values, was studied. the release of metals from sediments, leaks of pollutants from sludges and wastes, and some remedial approaches are discussed.
