Metals are natural constituents of rocks, soils, sediments, and water. However, great changes have occurred regarding the global assessment of critical chemical substances after the Industrial Revolution, approximately 200 years ago, challenged those regulating systems that took millions of years to evolve. A clear example is the Gulf of Mexico, where the presence of metals in its coastal ecosystems answers to the introduction of pollutants by river inputs, among which two of the greatest deltaic systems of the world, i.e., the Mississippi River in the United States and the Grijalva Usumacinta Basin in Mexico, are prominent. Additionally, industrial and commercial activities that have developed in the giant harbor complexes of Brownsville, Corpus Christi, Houston, Galveston, and New Orleans in the U.S. and those of Tampico-Madero, Altamira, Veracruz, Coatzacoalcos-Minatitlan, Dos Bocas, and Ciudad del Carmen in Mexico have greatly contributed to the large volume of toxic wastes dumped into the waters of the Gulf, including a large variety of metals.
