Common symptoms include severe stomach pain, numbness, hair loss and long-term neurological complications.
Because it has no taste or smell, Thallium Sulphate earned the nickname “the perfect poison.”
It was previously used in pesticides and limited medical treatments but is now heavily restricted worldwide.
In the United States, its use is strictly controlled by Occupational Safety and Health Administration.
It is also regulated by the Environmental Protection Agency due to its public health risks.
Exposure can be fatal if not treated early, making its handling subject to international safety standards.
Questions have emerged about why such a dangerous substance would be imported into Nigeria.
Concern remains over its relevance to national security and the purpose of its intended use.
Citizens are calling for transparency on the circumstances surrounding the reported importation.
