[Malonyl dialdehyde concentration in red blood cells of workers engaged in the production of iron-manganese alloys].

The increased concentration of malonyl dialdehyde (MDA) in peripheral blood red cells of workers engaged in the production of iron-manganese alloyes was found. That provide evidence that increased peroxidation of red blood cell lipids induced by the production of free radicals is due to factors present in the occupational environment.
