Public attention has turned to Thallium Sulphate following claims involving Nuhu Ribadu and Nasir el-Rufai.

Thallium Sulphate is a highly toxic, colourless and odourless inorganic salt once used as a rodenticide and insecticide.

It was banned in many countries due to its extreme danger to humans and animals.

The chemical acts as a cumulative poison, damaging the nervous system and disrupting normal body functions over time.

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.
