Study results showed the highest detectable concentrations of heavy metals were lead, barium and chromium. All samples except for lead had less than or the same levels expected for an urban area.The median levels of lead detected in seven samples from play areas (400 mg/kg) and three samples from residential areas (1200 mg/kg) were four times the levels for Texas overall. And these likely were underestimated because they did not account for lead-based paint or automotive fuel.
