Specific problems with inorganic pollution

Traditionally, inorganic chemistry has been a great contributor to our environmental problems. Historically problems of this type arose long before the current environmental crisis. Most often inorganic pollution results from the presence and concentration of a specific element rather than from the particular molecule in which the element is foimd in nature. Mercury poisoning and itai itai disease lead and its multiple toxic effects, or any of the problems associated with high concentrations of certain transition metals all relate to the specific element.
