Lead PoisoningHEALTH EFFECTSIn 2017, 829 children screened were found to haveelevated blood lead levels (BLLs) above the CDC referencevalue of 5 μg/dL.Lead is traditionally found in paint, but children can beexposed through non-traditional sources such as toys,candies, jewelry, cosmetics, and more.Lead poisoning can lead to severe adverse health effects,with most behavioral and learning impairmentsmanifesting at BLLs 5 μg/dL.4

Air Pollution SourcesMETAL RECYCLERIES, CONCRETE BATCH PLANTS, CONCRETE CRUSHERS8
Neighborhood Pollution SitesCMC METAL RECYCLERYData collected from risk assessmentsconducted at CMC Metal Recycler Northand South has shown an increase incarcinogenic risk for adult residents frominhalation of metals: Arsenic, Cadmium, Cobalt, and Nickel9
Neighborhood Pollution SitesUNION PACIFIC RAILROAD FACILITYRailroad ties were dipped in creosote,a preservative that is listed by the EPAas a cancer-causing chemical.Creosote emits harmful fumes andleaches into the surrounding soil.There have been concerns regardingcancer deaths in the nearby areas.The railroad site is in close proximityto Dogan Elementary School, leadingMap of affected residencesto concerns of children beingaffected.10
Concrete Batch PlantsThere are a total of 88 concrete batch plants in the city limits of various operational statuses.Since 2016 the Bureau of Pollution Control and Prevention has conducted over 40investigations of concrete batch plants within the City’s limits and found more than 40violations of TCEQ Standard Air Permit and City Ordinances.Violations included insufficient dust controls, nuisance conditions, inadequate bufferdistances (i.e., for locating of stockpiles) among others.11
