Metol is certainly under suspect here. OTOH as early as 1939 Agfa wrote in their lab-manual ("Das große Agfa Laborhandbuch") that dermatitis caused by Metol was due to a byproduct of the process. That process had been changed around that time and they claimed that recent (in 1939) Agfa-Metol should be completely safe.
