During the 19th and 20th centuries, the United States was the largest lead-producer in the world. Lead was manufactured for industrial and commercial purposes. As a paint additive, lead decreased dry time, enhanced durability and resisted moisture. In combustion engines, tetraethyllead functioned as an anti-knocking agent, improving the fuel’s octane rating The former technology localized lead around homes and buildings, the latter spread lead pollution along roads and highways. Today, the cities where lead was manufactured and used struggle to address the ubiquity of lead toxicity through the development of new technologies.
