Biomonitoring of Metal Exposure During Additive Manufacturing (3D Printing).

Background: Additive manufacturing (AM) is a rapidly expanding new technology involving challenges to occupational health. Here, metal exposure in an AM facility with large-scale metallic component production was investigated during two consecutive years with preventive actions in between.

Methods: Gravimetric analyzes measured airborne particle concentrations, and filters were analyzed for metal content.

High levels of isocyanic acid in smoke generated during hot iron cauterization.

Pyrolysis of nitrogen containing biofuels generates isocyanic acid (ICA) and we here studied if ICA also is present in cauterization smoke. Air sampling was performed when animal technicians that had developed airway symptoms worked with dehorning. Tissue heated in a laboratory model was used to mimic cauterization.

Risk factors for neck pain among forklift truck operators: a retrospective cohort study.

Background: No previous research has been performed into neck pain among forklift operators. This is a common complaint among these workers, who number around 150,000 in Sweden and six million in Europe. The aim of the study was to examine long-term exposure to unnatural neck positions among forklift operators as a risk factor for neck pain.
