In December, Reuters published a map on childhood lead poisoning across the nation. The story and accompanying map, “Off the Charts: The thousands of U.S. locales where lead poisoning is worse than Flint,” looked at where children were tested for lead and how many had high levels of the metal in their blood. Severe lead poisoning can lead to seizures, coma and death, according to the Centers for Disease Control. For children, there is no such thing as a safe exposure to lead, which causes permanent neurological damage and behavioral disorders. Even though lead paint and lead additive in gasoline were banned decades ago, the ongoing Flint, Michigan emergency highlighted that lead poisoning is still a problem in the United States.
