Clair Patterson was a geochemist focused on determining the age of the Earth. Herbert Needleman was a pediatrician treating inner-city children. But in the chemistry lab and the hospital ward, they met a common enemy: lead. It was literally everywhere. Though few people worried about it at the time, lead was also toxic. In Toxic Truth, journalist Lydia Denworth tells the little-known stories of these two men who were among the first to question the wisdom of filling the world with such a harmful metal.
