  Using the semiclassical WKB approximation and Hamilton-Jacobi method, we
solve an equation of motion for the Glashow-Weinberg-Salam model, which is
important for understanding the unified gauge-theory of weak and
electromagnetic interactions. We calculate the tunneling rate of the massive
charged W-bosons in a background of electromagnetic field to investigate the
Hawking temperature of black holes surrounded by perfect fluid in Rastall
theory. Then, we study the quantum gravity effects on the generalized Proca
equation with generalized uncertainty principle (GUP) on this background. We
show that quantum gravity effects leave the remnants on the Hawking temperature
and the Hawking radiation becomes nonthermal.
