"Cell Phones are Among the Fastest Growing Types of Trash - The average North American gets a new cell phone every 18 to 24 months, making old phones—many that contain hazardous materials like lead, mercury, cadmium, brominated flame retardants and arsenic—the fastest growing type of manufactured garbage in the nation. According to the U.S. Environmental Protection Agency (EPA), Americans discard 125 million phones each year, creating 65,000 tons of waste." (Quoted from article)
