(American Chemical Society) A truck kicking up dust as it speeds down a dirt road is a typical image in country music videos. But this dust from unpaved roads is also an environmental and health hazard. To prevent dust clouds, some states treat dirt motorways with oil and gas wastewater. Now one group reports in Environmental Science & Technology that this wastewater contains harmful pollutants that have the potential to do more harm than good.
