"Environmental chemistry focuses on understanding the planet's most common pollutants. Some of them, such as lead, uranium, and methane, occur naturally. Others, such as DDT, are manufactured by humans. How do they pollute? How do they get into our food, water, and air -and then into our bodies? What are the consequences to human, plant, and animal health? Through an in-depth, accessible, and intriguing look at metals, pesticides, fuels, and nuclear energy, you'll understand the chemistry of modern environmental challenges."--Inside dust jacket.
