State health officials say they have not discovered a single cause for high lead levels found in some children in Saline County.

The Kansas Department of Health and Environment has been investigating since routine physical exams found 32 children in and around Saline County with elevated levels of lead in their blood.

The health department has notified some Salina families that the lead poisoning was caused by conditions inside their homes.

Department spokeswoman Cassie Sparks says the agency’s findings will be officially released in September but the letters are going out to the families so they can begin addressing lead-causing issues in their homes, such as old lead paint.

She says inspectors found no common link between all the cases.
