    Presentation Transcript
    1. Lead

    2. Causes and Indicators • The main causes of lead pollution are from oil, gasoline, and many lost fishing weights • Any spilled oil or gasoline releases lead which is part of its chemical structure • Many fishing weights are lost due to snags on the bottom or fish breaking the line from being to big or the fisherman having the drag too tight

    3. Human Effects • Lead effects all of the human organs and causes a great amount of damage such as hearing loss and tooth decay • The kidneys are damaged at high levels and gout builds up • In the heart it causes high blood pressure, and increases your chances of heart disease • Most of the problems though are related to the nervous system and the brain

    4. Environmental Effects • Lead affects all living things • Any lead in our oceans is absorbed by the wildlife and when we eat that wildlife we then absorb it • Lead gets into the ocean mostly from all the boats
