  One might expect far away from physical black holes that quantum field
quantisation performed in Minkowski space is a good approximation. Indeed, all
experimental tests in particle colliders reveal no deviations so far.
Nevertheless, the black holes should leave certain imprints of their presence
in quantum processes. In this paper, we shall discuss several local imprints of
small, primordial evaporating black holes in quantum electrodynamics in the
weak gravity regime. Physically this can be interpreted as being macroscopic
manifestations of vacuum fluctuations.
