Lead poisoning has been a hazard for centuries. Some scholars believe that the decline of the Roman Empire can be traced, in part, to high levels of lead in water from containers and pipes, and from wine that was stored in leadglazed containers. If we presume that the typical Roman water supply was saturated with lead carbonate, PbCO₃ (K_sp = 7.4 × 10^-14), how much lead will a Roman ingest in a year if he or she drinks 1 L/day from the container?
