Lead pollution

Poison. Neurotoxin. Credited with the Fall of Rome. Need we say more? Yes, we do.

EPA lists the most common effects of long-term exposure to lead as:

• Damage to the brain and nervous system
• Behavior and learning problems, such as hyperactivity
• Slowed growth
• Hearing problems
• Headaches
• Reproductive problems (in both men and women)
• High blood pressure and hypertension
• Nerve disorders
• Memory and concentration problems
• Muscle and joint pain

According to the US government standards, lead is about 180000 times as harmful as carbon dioxide (How we know that?).
