What is the fatal dose range of barium that may harm the nervous system and heart?

• A. 150 to 250 mg
• B. 400 to 475 mg
• C. 550 to 600 mg
• D. 800 to 1000 mg

Answer: (C)

The fatal dose range of barium that can adversely affect the nervous system and heart generally falls within the range of 550 to 600 mg. Barium is a heavy metal that, when ingested in significant quantities, can lead to serious health complications, including muscle paralysis and cardiac abnormalities. The symptoms of barium poisoning can be severe, as it interferes with potassium levels and disrupts normal cellular processes, particularly in muscle and nerve tissue. Understanding this fatal dose range is critical for environmental health specialists as it underscores the importance of monitoring and controlling barium levels in drinking water, industrial discharges, and other environmental sources to protect public health. Knowing the toxicity levels also assists in establishing safety guidelines and appropriate interventions in cases of exposure.
