Chlordane is a man made chemical and popular pesticide that was offered in the United States from 1948-1988.

Barium is a natural, silvery-white earth metal. Highly reactive with air, barium is not found naturally in pure forms but as a component of ores.

Barium exposure, however, can cause serious health concerns. (more…)
