According to Sabina Hoppe, head of the environmental protection unit at the County Administrative Board, further sampling is pending before the board, the supervisory authority for the operation, decides how to act, P4 Norrbotten reports.
Approximately 25 workers, both blue-collar and white-collar, at SSAB's Luleå site have fallen ill with symptoms such as nausea, nosebleeds and headaches in connection with earthworks during the construction of the new steel mill.
The soil consists of dredged material from the sea and slag, which is a residual product of steelmaking.
On April 3, SSAB paused work, and the union has also imposed a safety stop on operations.
