Solong was carrying 15 containers of the chemical at the time of the incident, according to maritime data provider Lloyd’s List Intelligence.
Sodium cyanide is used in metal processing, dye production, and photography. The UK Health Security Agency (UKHSA) describes it as a white, crystal-like solid with a faint almond odour.
Exposure to cyanide salts can cause symptoms such as headaches, dizziness, confusion, and, in severe cases, respiratory or cardiac failure.
Dr. Mark Hartl, associate professor of marine biology at Heriot-Watt University, stated that sodium cyanide is highly soluble in water and toxic to aquatic life. If heated, it can also generate a harmful gas. However, it remains unclear whether any of the chemical has entered the water or been burned in the aftermath of the collision. He noted that marine organisms such as fish tend to avoid contaminated areas.
The Humber Coastguard issued a distress call following the collision, requesting assistance from vessels with firefighting or search and rescue capabilities. Crew evacuations took place shortly after.
Authorities are monitoring the situation for any environmental impact.
