Acute lead poisoning in an indoor firing range

Abstract

The presented case demonstrates that acute lead poisoning may occur due to just short-term exposure to a mixture of lead-con-taining dust and ammunition. Such exposure may result in high blood lead levels persisting for years in the absence of any symptoms. A middle-aged male with a history of an approximately 7-day cleanup of an old recreational firing range with large ammunition and dust deposits presented to an emergency department with abdominal pain, dyspnea, fatigue and impaired cog-nitive function. Given his occupational history, specific tests were performed that showed high lead concentrations in both blood and urine. The patient was diagnosed with acute lead poisoning. He was started on chelation therapy that improved both clin-ical and laboratory parameters. Over a subsequent nearly 3-year follow-up, the patient’s blood lead levels fluctuated and con-tinued to be increased. Given the absence of other sources of lead exposure, these were likely due to the formation of bone deposits.
