This would happen due to the substances in the salamander's skin, because of the sulfur they would be able to survive.
Acid rain is a phenomenon that occurs when sulfur and nitrogen oxides released into the atmosphere by pollution react with rainwater and generate acids.
Atmospheric air is formed by various chemical elements, including gases such as oxygen (O2), nitrogen (N2), carbonic (CO2), Xenon (Xe) and Radon (Rn), in addition to other variable components. Smoke is one of the harmful components that is produced by some industries and released by automobiles.
There are industries that do not have filters in their chimneys. In this way, black smoke with soot is released into the air, composed of lead (Pb), zinc (Zn) and cadmium (Cd), which depending on the quantity can be harmful to living beings.
Cars also emit smoke that contains sulfur oxides (SO2 and SO3), carbon monoxide (CO), nitrogen dioxide (NO2) and hydrocarbons.
All these pollutants, present in the smoke, when reacting with water vapor in the atmosphere, form sulfuric acid (H2SO4) and nitric acid (HNO3), thus characterizing acid rain.
