ST. LOUIS, Mo. – A Washington University study shows that St. Louis residents in poor, segregated neighborhoods are at a greater risk of cancer from air contaminants. Christine Ekenga, an assistant professor at the school and the study’s lead author, told the St. Louis Post-Dispatch the pollutants that conferred the greatest dangers were traffic-related. The findings support the university’s other recent research that details how St. Louis is plagued by inequalities. The city’s stark racial divide makes it one of the most segregated in the U.S. and contributes to differing outcomes that include asthma rates, exposure to lead and inadequate access to healthy food.
