Sources of lead in soil include which of the following?

Explanation:
Lead in soil mainly comes from deteriorating lead-based paint and past emissions from leaded gasoline. When paint on buildings flakes or dust from sanding and scraping settles, it contaminates nearby soil. Likewise, burning leaded gasoline left tiny lead particles in the air that settled onto soils, especially along roads and in urban areas. Old pipes are more commonly a source of lead in drinking water rather than soil, fertilizers can contribute only trace amounts in some cases, and sea spray generally contains very little lead. So the combination of chipped paint and gasoline emissions best describes the primary soil lead sources.
