In 2006, Austin, Texas, became the first city in the country to ban a commonly used pavement sealant over concerns that it was a major source of cancer-causing compounds in the environment. Eight years later, the city's action seems to have made a big dent in the targeted compounds' levels -- researchers now report that the concentrations have dropped significantly.
