	Plant Preparations - Material prepared from plants for medicinal purposes.
	Radioactive Pollutants - Radioactive substances which act as pollutants. They include chemicals whose radiation is released via radioactive waste, nuclear accidents, fallout from nuclear explosions, and the like.
	Soil - The loose surface material of the earth in which plants grow. (Webster, 3d ed)
	Tars - Viscous materials composed of complex, high-molecular-weight compounds derived from the distillation of petroleum or the destructive distillation of wood or coal. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
